【摘要】 对克拉玛依油田九区南石炭系火山岩油藏低渗透储集层破裂产生的微地震波进行实时监测,根据地球物理、岩石力学、储集层改造及微震波信号等建立数据库,并用人工裂缝监测系统程序对数据库进行一系列解释处理,结合区块构造、储集层物性及压裂参数对监测结果进行综合分析,最终查明压裂层段人工裂缝的方位、长度、高度、产状和地下最大水平主应力方向等信息,从而为此类储集层水力压裂改造参数优化及制定下一步开发调整方案提供依据。更多还原

【Abstract】 Real-time micro-seismic wave monitoring technology for artificial cracks in the process of hydraulic fracturing was applied to the Carboniferous volcanic reservoir with low permeability in southern District-9 in Karamay oilfield,the information such as orientation,length,height,occurrence and maximum principal stress direction of artificial fractures in fracturing intervals can be finally determined by building up database of geophysics,rock mechanics,reservoir reformation and micro-seismic wave signal,etc.,integrated with a series of interpretation and processing of the cracks and fractures,based on regional structure,reservoir property and fracturing parameters,so as to provide scientific basis for optimizing such reservoir hydraulic fracturing parameters and designing next development scheme.更多还原
