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。
The microseismic wave produced by the rupture of the low permeability reservoir in the South Carboniferous volcanic reservoir in the 9th district of Karamay Oilfield was monitored in real time. The database was established based on the geophysics, rock mechanics, reservoir alteration and microseismic signals. The artificial fracture monitoring system program After a series of interpretation and processing of the database, combined with the block structure, reservoir physical properties and fracturing parameters, the monitoring results are comprehensively analyzed to finally find out the location, length, height, occurrence and underground maximum level of artificial fractures in the fractured zone The main stress direction and other information, so as to optimize the hydraulic fracturing parameters for such reservoirs and formulate the next step in the development and adjustment program.
