在地应力场理论的指导下,通过对文23 气田构造格局的分析研究,将文23 气田划分为3 个不同地应力场特点的区域,并结合文23 气田1995～1997 年间14 口井的压裂裂缝监测资料,弄清了压裂裂缝的发育程度与地应力场之间的内在关系,为下步气井压裂设计提供了科学依据,并为类似气田的压裂改造提供了宝贵的借鉴经验。

With the theory of insitu stress field ,the structural framework of Wen 23 Gas Field is studied and is divided into three different insitu stress fieldes regions. Combining with the monitoring data of facturing fissures in 14 wells of Wen23 Gas Field during 1995～1997 , the relations between growth strength of fracturing fissure and in-situ stress field is realized , offering scientific evidence of designing gas well facturing program.
