低渗油藏人工裂缝监测技术在现河地区的应用

摘要

针对高压低渗透油藏渗透率低、孔隙度小的特点,在压裂改造时进行裂缝监测,根据监测出的裂缝方位(方向)、裂缝长度、裂缝的高度(范围)和产状以及地下主应力的方向,为下步布井和井网调整提供了依据.2008年以来,现河地区已成功实施裂缝监测79井次,为低渗透油藏的高效开发提供了有力支持.%Aiming at the characteristics of low permeability and small porosity of high pressure low permeable reservoir, fracturing mapping was employed during transformation. Information of fracture azimuths (direction) , length, height (range) , occurrence and directions of underground principle stress provides basis for oncoming well placement and well network optimization. Since 2008, 79 fracturing mapping have been performed successfully in Xianhe region, which offers great support for the increasing development of low permeable reservoir.
