孝泉气田CX108井侏罗系储层压裂施工失败原因分析

孝泉气田我系蓬莱镇组气藏属致密砂岩气藏，储层压裂改造技术一直没有突破，障碍了对该区块地勘探开发步代，本文重点以ＣＸ１０８井裂度验为例，从地质因素和压裂施工参数入手，对造成该井压旗子工失败的多种原因作出详细分析，据此提出一系裂建议，以期为孝泉为气田压裂改造技术的突破作出有益的探索。

ANALYSIS ON THE FAILURE CAUSE OF WATER FRACTURINGIN JURASSIC RESERVIOR OF CHUANXIAO WELL 108 IN XIAOQUAN GAS FIELD

The Penglaizhen Formation of Jurassic reservoir of Xiaoquan gas field belongs to the compact sandstone reservoir,which hampered the exploration and exploitation of gas and was difficult in the breakthrough of water fracturing technique.Taking CX 108 well as an example and on the basis of geological factors and working parameters of water fracturing,the various causes leading to the failure of water fracturing were analysed thoroughly.Suggestion was made for the reform of water fracturing technique.
