【摘要】 微地震监测技术的现场应用是通过监测注水过程中产生的微震波,来确定出水驱前缘位置、优势注水方向、注水波及面积等资料,进而确定出裂缝分布的规律。在简要介绍无源微地震监测技术基本原理的基础上,结合地质动、静态资料,对微地震法在水驱前缘测试大庆西部外围低渗透油田的应用效果进行了分析。现场应用效果证明,微地震监测技术在低渗透油田裂缝研究领域具有良好的应用前景,对提高低渗透裂缝型油田开发效果具有十分重要的意义。更多还原

【Abstract】 Microseismic monitoring is capable of determining locations of waterflood front drive,optimal waterflood direction,waterflood wave,water spread area and etc.,and then interpolates fracture patterns,based on microseismic wave occurred from waterflooding.After brief description of principles of passive microseismic monitoring,this paper analyzes results of application of microseismic monitoring on waterflood front at Daqing Oilfield western periphery,in combination of dynamic and static geological information.Field application asserts that microseismic monitoring has good prospects in fracturing studies of low permeable oilfield,and is great importance to improve recovery of low permeable oilfield.更多还原
