近日,由中油测井公司承担的长庆油田陇东致密油区2口水平井顺利完成,国产化桥塞射孔联作施工完美收官。桥塞射孔联作工艺是目前国内外针对页岩气、致密油气等非常规储层进行改造的主要技术和工厂化压裂作业的核心技术。然而在国内,该工艺的核心技术——分级点火系统及易钻复合桥塞却主要依赖进口。为满足长庆油田规模开发致密油气储层和“立体射、分段压”的需求,并有效降低施工费用,中油测井公司在技术引进、集成的基础上,经过3年多努力,相继攻克了分级点火系统、易钻复合桥塞等5项关键技术,
Recently, 2 horizontal wells in the Longdong tight oil zone of Changqing Oilfield undertaken by the China Petroleum Logging Company were successfully completed and the domestically made bridge-piercing perforation joint construction was completed perfectly. Bridge plug perforation linkage technology is currently the main technology for shale gas, tight oil and other unconventional reservoirs transformation and the core technology of the factory fracturing operation. However, in China, the core technology of the process - grading ignition system and easy to drill composite plug is mainly dependent on imports. In order to meet the needs of developing tight oil and gas reservoirs and “three-dimensional shot and sub-pressure” of the scale of Changqing Oilfield and effectively reduce the construction cost, CNPC logging company, after more than three years of hard work on the basis of technology introduction and integration, Have grasped the grading ignition system, easy to drill composite plug and other five key technologies,
