中国石油网消息：记者4月9日获悉，由新疆油田采油工艺研究院（监理公司）、勘探事业部、工程技术部联合攻关的“天山气田超深超高压气井机械分压合采一体化”技术，在天山气田HT1-002井成功应用。投产后，该井油压、无阻流量较邻井平均分别提升37兆帕和2.6倍，刷新区块开发纪录，填补了新疆油田在该领域的技术空白。

China Oil News: On April 9th, a reporter learned that the "Mechanical Pressure-Depression Combined Production Integration Technology for Ultra-Deep and Ultra-High Pressure Gas Wells in the Tian Shan Gas Field" jointly developed by the Oil Production Technology Research Institute (Supervision Company), Exploration Department, and Engineering Technology Department of Xinjiang Oilfield has been successfully applied in the HT1-002 well of the Tian Shan Gas Field. After production, the oil pressure and unobstructed flow rate of this well have increased by 37 megapascals and 2.6 times respectively compared to adjacent wells, setting a new record for the development of the block and filling the technical gap in this field for Xinjiang Oilfield.

天山气田位于准噶尔盆地南缘，气藏埋深超7000米，地层压力系数在2.0以上，地质构造复杂、储层致密，开发无成熟经验。

The Tianshan gas field is located at the southern edge of the Junggar Basin. The gas reservoirs have a burial depth of over 7,000 meters, and the formation pressure coefficient is above 2.0. The geological structure is complex and the reservoirs are dense. There is no mature development experience for this field.

新疆油田攻关团队坚持问题导向、多年持续攻坚，首创由大通径组合油管、双级永久式封隔器、直连油管、压裂滑套等核心工具构成的“天山气田超深超高压气井机械分压合采一体化”技术。

The research team of Xinjiang Oilfield has adhered to a problem-oriented approach and has been continuously working on it for many years. They have pioneered a "mechanical pressure-sharing and joint production integration technology for ultra-deep and ultra-high-pressure gas wells in the Tianshan Gas Field", which is composed of core tools such as large-diameter combined tubing, double-stage permanent packers, direct-connected tubing, and fracturing sliding sleeves.

该技术创新应用超长直连油管，使压裂排量从每分钟2.3立方米提升至3.7立方米，增幅超60%。在压裂工艺上，科研团队创新形成分层设计方法，配套全程加重、变交联变排量、缝内控压安全压裂技术，首次在超深小井筒条件下成功实现两层机械分压与大规模加砂，压后获高产工业气流。监测显示上下层产量贡献分别为57%、43%，有效改善了层间动用不均的状况。

This technological innovation adopts ultra-long direct connection tubing, which increases the fracturing flow rate from 2.3 cubic meters per minute to 3.7 cubic meters per minute, an increase of over 60%. In the fracturing process, the research team innovatively developed a layered design method, along with a complete set of technologies such as full-weighting, variable cross-linking and variable flow rate, and internal pressure control for safety fracturing. For the first time, this technology successfully achieved mechanical pressure division between two layers and large-scale sand addition under ultra-deep small wellbore conditions, resulting in high-yield industrial gas flow after fracturing. Monitoring showed that the production contributions of the upper and lower layers were 57% and 43% respectively, effectively improving the uneven utilization of the layers.
