摘要
应用岩石声发射资料研究计算现令储层地应力及应力场分布,预测储层天然裂缝的分布和形成人工缝裂的形态,以降低裂缝性油气藏和中低渗透油气田井网部署与注水(含高压注水)开发的风险,减少储层压裂改造的盲目性,实现油田的合理开发。安棚油田的实践表明,利用该方法求得的地应力剖面资料和同一储层地应力平面分布资料较为准确、可靠,具有一定的推广应用价值。
By use of acoustic data, earth stress and stress field distribution in present reservoirs are studied and calculated, and the distribution of natural fractures and the shape of created fractures are predicted to reduce the risk in pattern layout and water injection (including high pressure water injection) and uncertain fracturing in mid - low permeability reservoirs. It has been showed by practice in Anpeng oilfield that, the earth stress profile and plane distribution of earth stress in the same reservoir derived by this method are accurate, reliable, and worthy of popularization.
