微地震裂缝监测技术在油水井压裂和注水评价中的应用

微地震裂缝监测技术使用现代声发射技术中平面任意三角形阵列的源定位方法,结合计算机数据处理技术和相关的油田地质参数,可在屏幕上实时显示数千米深岩层人工裂缝的变化形态和方位状况,开创性地应用高新技术手段指导油田开采,达到了提高工作效率、增加原油产量的目的。文章以微地震裂缝监测技术对火烧山油田压裂井监测及彩南油田注水井组监测结果,评价了注水井组的水窜方向和压裂井裂缝的形态、方向及长度,对油田压裂效果评价和油田后期注采井网调整起到了重要的指导作用。

Application of Micro Seismic Monitoring Technique in Fracturing of Water&Oil wells and Evaluting of Water Injecting

Using acoustic location method in plane random triangular array applied in modern acoustic emission technique,combined computer data processing technology and associated oilfield geology data,the micro seismic monitor technique makes it possible to display on screen in real time the shape changing and location status of artificial fractures which occurring at several kilometers deep rock layer.This Innovating application of high and new technology method can be used as the guidance for oil field’s development,thus the objective of raising working efficiency and increasing oil well production can be achieved.The paper based on the results of micro seismic fracture monitoring technology applied in monitoring the fractured wells at HuoShaoshan oil field and water injection wells at CaiNan oil field,by evaluting the water breakthrough direction and fractures’ shape,direction and length in fractured wells,which can be a guideline for evaluting the reservoir fracturing results and the well pattern adjustment at later production stage.
