微地震波监测技术在水驱前缘与裂缝研究中的应用——以乾安油田为例
Application of microearthquake wave monitoring technology to the research of the waterflood front and fissure-taking Qian’an Oilfield as an example
【摘要】 应用潜入式水驱前缘和裂缝监测系统,通过微地震信息的现场监测和解释,结合生产动态及其他监测资料综合分析,描述了乾安油田注水开发状态下水井井周裂缝发育特征,确定了水驱前缘位置,研究了地下油水运动规律,结果表明,乾安油田水驱前缘"指状"突出现象普遍,油井排100m附近剩余油较多。
【Abstract】 Using submersible waterflood front and fissure monitoring system,the fissure character around water wells under waterflood development in Qian’an Oilfield is described based on field monitoring and interpretation on microearthquake information together with comprehensive analysis of production performance and other monitoring data.The position of waterflood front is determined,and the regularity of oil-water motion underground is studied.It provides reliable evidence for the research of remaining oil distribution and the adaptive modification of well pattern.
