摘要:
针对山西某区块传统压裂测试效率低、资源配置不合理问题，在常规测试工艺基础上，结合该区块致密砂岩气的开发方式，设计出适合于本区块的压裂测试排液一体化管柱,形成了致密砂岩气井压裂测试排液一体化工艺技术。管柱采用RTTS封隔器进行油套管封隔；压裂时通过油管注入压裂液；压裂放喷后不动管柱直接连续气举生产。在本区块共应用9井次，井口最高施工压力57 MPa，未出现管柱串漏现象，施工成功率100%。该工艺操作简便、安全性高，为致密砂岩气井的增产挖潜提供了技术支撑。
Abstract:
In view of the problems of low efficiency of traditional fracturing test and unreasonable resource allocation in a block in Shanxi Province, combining with the development method for tight sandstone gas of this block, an integrated fracturing test and drainage pipe string suitable for this block was designed on the basis of conventional testing technology, and the integrated technology of fracturing test and drainage was formed for tight sandstone gas well. The pipe string is sealed with RTTS packer. Fracturing fluid is injected through tubing during fracturing. The well produces with gas lift directly and continuously after fracturing and discharge. In this block, this string was applied in 9 wells with the highest wellhead operating pressure of 57 MPa. There is no pipe string leakage, and the operating success rate of 100%. This technology is userfriendly and safe, which provides a technical support for stimulation and exploration of tight sandstone gas wells.
