中国石油网消息：5月26日，从冀东油田获悉，该油田多方协同开展技术攻关，在佳45-5C2井首次试验应用低压气藏射压投一体化工艺，有效解决了小井眼低压储层改造难题，为该油田西部探区小井眼低压储层高效开发开辟了新路径。

China Oil News: On May 26th, the Jidong Oilfield announced that through multi-party collaboration and technological research, they successfully conducted the first trial application of the integrated technology for pressure injection and pressure release in low-pressure gas reservoirs in Well Jia 45-5C2. This effectively solved the problem of small-borehole low-pressure reservoir modification, opening up a new path for the efficient development of small-borehole low-pressure reservoirs in the western exploration area of the oilfield.

佳45-5C2井所在的佳县区块，储层物性敏感、压力系数低，且多为四寸半小井眼，传统作业易伤害储层，影响增产效果。冀东油田采油院按照地质工程一体化思路，联合西部项目部靶向攻关，创新整合射孔、环空加砂、压裂改造、快速投产等多道工序，构建了适配西部小井眼低压储层的低压气藏射压投一体化工艺。

The Jia County block where Well Jia 45-5C2 is located has sensitive reservoir properties, a low pressure coefficient, and mostly uses four-inch-and-a-half small wellbores. Traditional operations are prone to damaging the reservoir and affecting the production enhancement effect. The Oil Production Institute of Jidong Oilfield, following the integrated approach of geology and engineering, jointly targeted the western project department to conduct in-depth research. They innovatively integrated multiple processes such as perforation, annular sand addition, fracturing modification, and rapid production, and constructed an integrated low-pressure gas reservoir pressure injection and production technology suitable for small wellbores and low-pressure reservoirs in the western region.

针对西部四寸半小井眼特点，技术团队突破油田东部老区五寸半井眼成熟工艺限制，专项优化改进井下工具，精准匹配小井眼施工工况。

Taking into account the characteristics of the 4.5/8-inch small wellbores in the western area, the technical team broke through the limitations of the mature process in the eastern old oilfield area of 5.5/8-inch wellbores, specifically optimized and improved the downhole tools, and precisely matched them with the working conditions of small wellbores construction.

在试验过程中，低压气藏射压投一体化工艺实现单趟管柱连续施工、不动管柱直接投产，相较常规打桥塞、多轮次起下管柱等作业，具备短周期、低成本、低伤害核心优势。

During the test process, the integrated pressure injection and well completion technology for low-pressure gas reservoirs enables continuous construction with a single pipe string and direct production without moving the pipe string. Compared with conventional operations such as installing bridge plugs and multiple rounds of pipe string lifting and lowering, this technology has the core advantages of short cycle, low cost and low damage.

同时，大幅减少井筒扰动与入井液接触，从源头规避了储层污染与储层伤害，最大程度保留了储层的原始渗流能力。

At the same time, significantly reducing the disturbance of the wellbore and the contact with the well fluid has effectively avoided reservoir contamination and damage at the source, and maximally preserved the original permeability capacity of the reservoir.
