西峰-合水地区长8油层压裂工艺技术研究

Research of Hydraulic Fracturing Technologies in Chang-8 Reservoirs of Xifeng-Heshui Area

在分析总结西峰-合水地区延长组长8油层前期勘探开发成功经验与认识的基础上，围绕提高单井产量这一中心目标。在室内评价、优化设计、现场试验、效果跟踪分析等方面开展了大量的工作，取得了较好的效果，初步形成了与该区长8储层地质特点相适应的主体改造技术及配套技术体系。

Based on analyzing and summarizing the successful experiences and understanding of exploration and production of Chang- 8 reservoirs in Xifeng-Heshui area, a lot of work has been done in hboratory evaluation, OPtimization design, in-sire testing, and result-tracing analysis, surrounding the central target of increasing the individual well production rate. Good results are obtained. The principal reservoir stimulation technology and supporting technology series are preliminarily formed, adaptable to geologic features of Chang-8 reservoirs in Xifeng-Heshui area.
