8月的陇东黄土塬，千沟万壑间井架林立、钻机轰鸣，油气开发热潮涌动。300公里外，长庆油田地球物理部办公室里，技术人员紧盯屏幕上的三维地震剖面，一条条地震波曲线层层展开，如同为地层做“巨型CT”，精准呈现地下构造、断裂走向与储层分布全貌。

In August, on the loess plateaus of Longdong, thousands of ravines and valleys are dotted with oil and gas drilling rigs and drilling machines, and the wave of oil and gas development is surging. 300 kilometers away, in the office of the Geophysical Department of Changqing Oilfield, technicians are closely monitoring the three-dimensional seismic profiles on the screen. One after another, the seismic wave curves unfold, like conducting a "mega CT" for the strata, precisely presenting the entire picture of underground structures, fault directions and reservoir distribution.

今年3月，长庆油田陇东油区石油开发物探技术示范区（简称物探技术示范区）正式成立，将物探技术服务的触角从研究室延伸到井场，打通了物探技术落地应用的“最后一公里”。5个月以来，21口完钻井平均油层钻遇率达92.6%，较地震一体化支撑技术落地前提升近10个百分点。

In March this year, the Petroleum Geophysical Survey Technology Demonstration Zone in Longdong Oil Area of Changqing Oilfield (referred to as the Geophysical Survey Technology Demonstration Zone) was officially established. This move extended the reach of geophysical survey services from the research department to the well site, thus breaking through the "last mile" for the application of geophysical technology. Over the past five months, the average oil layer encounter rate of 21 completed wells has reached 92.6%, an increase of nearly 10 percentage points compared to the level before the implementation of the seismic integration support technology.

从“参考图”到“导航仪”，精细解释提升开发精度

From "Reference Diagram" to "Navigator", detailed explanations enhance development accuracy

走进物探技术示范区办公室，墙上挂满了地震剖面图和生产动态图。技术人员正在对7个采油厂产建区2200平方千米的地震资料进行目标精细解释。截至目前，已交付基础研究图件97幅。

Entering the office of the Geophysical Survey Technology Demonstration Zone, one can see that the walls are covered with seismic profiles and production dynamics charts. The technicians are conducting detailed target interpretation of the seismic data covering 2,200 square kilometers in the production and construction areas of 7 oil production plants. Up to now, 97 basic research maps have been delivered.

“物探技术能不能真正发挥作用，关键看能不能和采油厂的生产实际接上轨。”物探技术示范区组长雷宇说。

Whether the geophysical exploration technology can truly be put into practice depends largely on whether it can be closely integrated with the actual production of the oil extraction plant, said Lei Yu, the leader of the geophysical exploration technology demonstration area.

过去，地震资料解释成果多以研究报告的形式交付，存在对地质信息理解深浅不一、应用效果参差不齐等问题。如今，物探技术示范区将地震基础研究、井位部署、随钻支撑、工程一体化、开发方案编制等5项技术服务全部嵌入生产一线，技术人员直接参与采油厂的井位论证和方案设计，让地震成果从“参考图”变成了“导航仪”。

In the past, the results of seismic data interpretation were mostly delivered in the form of research reports, which led to varying levels of understanding of geological information and inconsistent application effects. Nowadays, the geophysical exploration technology demonstration zone has integrated five technical services - seismic basic research, well location deployment, in-situ support, engineering integration, and development plan formulation - into the production front line. Technicians directly participate in the well location argumentation and scheme design of the oil production plant, transforming seismic results from "reference maps" into "navigation instruments".

在物探技术示范区，微断裂刻画、小幅度构造预测、薄储层描述等3项技术应用齐头并进，将开发区域目标的解释精度提升10%以上，井震构造误差全部控制在千分之二以内，优于行业标准。同时，技术人员依托人工智能断裂高清刻画、3D分级约束高精度反演等新技术，精准锁定浅层构造圈闭、厘清致密油砂体分布，为油田规模增储、高效建产筑牢了技术底座。

In the geophysical exploration technology demonstration area, three technologies - micro-fracture characterization, small-scale structure prediction, and thin reservoir description - are all advancing simultaneously. This has increased the interpretation accuracy of the development area targets by more than 10%, and all well-quake structural errors have been controlled within two thousandths, exceeding industry standards. At the same time, based on new technologies such as high-definition depiction of artificial fractures and 3D hierarchical constraint for high-precision inversion, the technicians have precisely identified shallow structural traps and clarified the distribution of tight oil sand bodies, laying a solid technical foundation for large-scale reserve increase and efficient production in the oilfield.

从“地质参谋”到“工程护航”，一体化防控破解钻井难题

From "Geological Advisor" to "Engineering Escort", Integrated Prevention and Control Solves Drilling Challenges

物探技术示范区的一项突破性进展，是首次将服务触角延伸至钻井和压裂工程领域，实现了物探技术从“地质参谋”到“工程护航”的跨越。

A breakthrough achievement in the geophysical exploration technology demonstration area is that it has for the first time extended its service reach to the drilling and fracturing engineering fields, achieving a leap from being a "geological advisor" to an "engineering escort" for geophysical exploration technology.

在彭阳地区，洛河组地层断裂发育，钻井过程中存在极高的井漏风险。技术人员借助三维地震敏感多信息融合断裂预测技术，精准刻画洛河组断裂发育强度与空间展布特征，形成“地震预警、轨迹优化、工程应对”一体化井漏防控流程。

In the Pengyang area, the Luhe Formation has developed fractures, and during the drilling process, there is an extremely high risk of well leakage. The technicians utilized the three-dimensional seismic sensitive multi-information fusion fracture prediction technology to precisely depict the development intensity and spatial distribution characteristics of the fractures in the Luhe Formation, and formed an integrated well leakage prevention and control process of "seismic early warning, trajectory optimization, and engineering response".

物探技术示范区技术负责人宋旭阳说：“有了地震断裂属性图，哪个区域断裂发育、哪个区域相对完整，一目了然。钻井轨迹可以提前绕开高风险区，实在绕不开的，也能提前做好堵漏预案。”

Song Xuyang, the technical director of the Geophysical Survey Technology Demonstration Zone, said: "With the seismic fracture attribute map, it's clear at a glance which areas have developed fractures and which areas are relatively intact. The drilling trajectory can be planned to avoid high-risk areas in advance. If it's really impossible to avoid, leakage prevention plans can also be prepared in advance."

目前，这套一体化防控流程已成功指导5口井精准规避漏失风险，钻井周期从30天压缩至12天，累计节约钻井成本与工时费用400万元。

At present, this integrated prevention and control process has successfully guided 5 wells to precisely avoid the risk of leakage. The drilling cycle has been shortened from 30 days to 12 days, and a total of 4 million yuan in drilling costs and labor expenses have been saved.

在吴起地区，技术人员通过精细刻画井轨迹与储层空间的位置关系，针对非甜点段定向优化射孔方案，推行差异化、精细化压裂改造模式，为36口水平井提供地震压裂方案优化建议，有效提升了地下储量动用效率。

In Wuqi area, technicians precisely delineated the positional relationship between well trajectories and reservoir spaces, and optimized the perforation plans for non-ideal sections. They implemented a differentiated and refined fracturing renovation model, providing seismic fracturing scheme optimization suggestions for 36 horizontal wells, effectively enhancing the utilization efficiency of underground reserves.

从“经验预判”到“实时迭代”，全程前置激活开发潜能

From "experience-based prediction" to "real-time iteration", continuously activate the development potential throughout the process.

随钻支撑是物探技术前移后最直观的成效之一。在钻井过程中，地层倾角、目标层深度等随时可能发生变化，邻井对比、现场经验预判的传统方式，在复杂构造区域极易出现轨迹偏差等问题，影响钻井质量。

Drilling while stabilizing is one of the most obvious benefits of advancing geophysical exploration technology. During the drilling process, the inclination angle of the strata and the depth of the target layer may change at any time. The traditional methods of comparing adjacent wells and making predictions based on on-site experience are prone to trajectory deviations in complex structural areas, which can affect the quality of drilling.

如今，物探技术示范区依托实时钻井数据，实现地震模型同步迭代、分秒级更新导向建议，让钻头全程有精准数据指引。长庆油田地球物理部开发项目管理科科长李鹏飞表示，实时更新的地震模型可提前预判前方地层变化，让钻井轨迹调整更精准、更及时，彻底解决了复杂地层钻井“跑偏”难题。

Nowadays, the geophysical exploration technology demonstration area utilizes real-time drilling data to achieve synchronous iteration of seismic models and update directional suggestions in fractions of a second. This enables the drill bit to be guided by precise data throughout the process. Li Pengfei, the director of the Development Project Management Department of the Geophysical Department of Changqing Oilfield, stated that the real-time updated seismic models can predict changes in the adjacent strata in advance, making the adjustment of the drilling trajectory more accurate and timely, and completely solving the problem of "deviation" in drilling through complex strata.

截至目前，技术团队累计支撑优化各类井型部署设计205口井，涵盖直井、定向井、长短水平井等，钻井精准度大幅提升。

As of now, the technical team has cumulatively supported and optimized the deployment designs of various well types for 205 wells, including vertical wells, directional wells, and long-short horizontal wells, etc. The drilling accuracy has significantly improved.

更深层次的变革体现在开发方案编制环节。以往油田编制开发方案以传统地质认识为核心，物探资料仅作为辅助参考，精准度不足。目前，物探技术已深度前置至4个主力油藏的2027年开发方案编制工作中，将断裂刻画、裂缝预测、构造精细解释和储层预测成果直接融入井位部署方案中，精准划分油气富集区与风险区，大幅提升了方案设计的针对性与科学性。

The deeper-level transformation is reflected in the development plan formulation process. In the past, when oil fields formulated development plans, the traditional geological understanding was the core, and geophysical data was only used as an auxiliary reference, resulting in insufficient accuracy. Currently, geophysical technology has been deeply advanced to the 2027 development plan formulation work of the four main oil reservoirs. The results of fault delineation, fracture prediction, detailed structural interpretation and reservoir prediction are directly integrated into the well location deployment plan, accurately dividing the oil and gas enrichment areas and risk areas, significantly enhancing the targetedness and scientificity of the plan design.

从后方研究到一线赋能，从辅助参考到核心支撑，长庆油田物探技术的全方位前移，打通了技术落地、成果转化、效能提升的全链条通道，为陇东油区高效勘探、精准开发、规模增产注入了强劲的技术动力。

From conducting research from the rear to providing frontline support, from offering auxiliary references to serving as the core support, the comprehensive advancement of geophysical exploration technology in Changqing Oilfield has opened up a complete chain of channels for technology implementation, transformation of achievements, and improvement of efficiency. This has injected strong technical impetus into the efficient exploration, precise development, and scale increase production in the Longdong Oilfield area.
