【摘要】 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。本文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。更多还原

【Abstract】 Microseism fracture monitoring engineering series modern times acoustic emission midplane at discretion triangular array of source Localization method ,combination computer data Micro seism fracture monitoring technology uses the source location method of plane random triangular array in modern acoustic emission,combining with computer data processing and correlative geologic parameters of the oilfield.The shape and azimuth of man-made fracture in several kilometres deep formation can be showed on screen in real time.This high and new technology method can be used to guide oilfield development and achieve the goals of improving work efficiency and increasing crude production.The fractured well monitoring result of Huoshaoshan oilfield and waterfloof injection well monitoring result of Cainan oilfield are used to evaluate the water breakthrough direction of water injection wells and shape,direction and length of fractured wells,which plays important role in directing flood pattern adjustment in anaphase oilfield evelopment.更多还原
