摘要
大庆油田杏北开发区萨、葡、高储层属河流三角洲沉积体系的砂泥岩薄互层 ,单井钻穿油层数目多 ,单层厚度与渗透率的层间和平面差异达上百倍 ,经过多年的注水开发 ,各类油层的动用状况存在很大差异。“八五”以来结合层系、井网加密调整 ,应用大量的测井资料 ,深入地开展储层精细描述和剩余油分布研究 ,逐步探索出一套高含水期多井储层精细描述技术 ,并将精细地质研究成果应用到油田开发调整挖潜上 ,取得了显著的效果。
Sa、Pu、Gao formations of Xingbei area in Daqing Oil Field feature thin alternating beds of sand and clay in an onshore river and river delta complex. Each well in this area encountered a lot of layers. Not only the thickness and permeability between and in layers differ hundreds of times,there are also large differences in the development of various layers. Combined with the adjustment of pay zone and infill of well pattern,using plenty of logging data,detailed description of reservoir and thorough study of residual oil have been carried out since“The Eighth Five Plan”.A series of techniques of detail description on multi well reservoir of high water cut period have been gradually developed. The application of these new techniques of adjustment oil field development achieved remarkable results
