摘    要:大型水力压裂技术是页岩气开发的核心技术之一,该技术使页岩储层形成复杂的网状裂缝,达到改造体积的目的。从我国页岩储层特征出发,在对国内页岩气压裂井施工技术等方面进行调研的基础上,结合现场施工实践经验,提出页岩气压裂施工中需要解决的关键难点。从断裂动力学角度对页岩气压裂缝网形成机理进行分析,并在此基础上,提出解决压裂施工过程中问题的方法,即适合于我国页岩气压裂施工设计的一般性原则。根据国内某口页岩气压裂井相关资料,结合研究内容,设计合理施工泵序,并利用专业页岩气压裂设计软件进行验证。

关 键 词:页岩  体积改造  优化设计  施工泵序

Abstract:Massive hydraulic fracturingShas become one of the key technology inSthe development of shale gas, which can form complexSfracture net and achieveSthe purpose of Stimulated Reservoir Volume (SRV)Sin theSshaleSreservoir. Proceed from the geologic characteristics of shaleSgas reservoir the key issue of fracturing operation on the operational design and procedure were raised in this paper, based on the research andSfieldSpractice of fracturing operation. The mechanism ofSfractureSnetSwas analyzed from theSangle ofSfractureSdynamics, and the generalSprinciples and related theory were established in this paper to solve the difficulties in the fracturing operation, which appropriate to the domestic terrestrial shaleSgas reservoir. Through the study of this paper, reasonableSprocedure of shale reservoir fracturing was designed and verified by numericalSsimulation software in this paper, according to the relevantSinformation of a domestic shaleSgas fracturingSwell.
Keywords:shale  stimulated reservoir volume  optimizing design  operation procedure
