摘要
依据层序地层分析原理对涠洲A油田流一段进行精细小层划分,确定了有利储层的纵向分布;通过分粒级建立储层渗透率计算模型对流一段储层进行精细解释,确定了纵向上的有效产层;最后通过储层反演及预测技术对本区主力产油层流一段Ⅴ1小层砂体平面展布情况进行了预测。根据预测结果部署了1口开发调整井进行开发生产,取得了良好的经济效益。
By using the principles of sequence stratigraphy analysis,Member 1 of Liushagang Formation in Weizhou A oilfield was refinedly divided into subzones,and its vertical distribution of favorabale reservoirs was determined.Then the reservoirs were refinedly interpreted by building permeability calculation models at various grain sizes,and the effective pays were vertically determined.Finally,the areal distribution of subzone sandbodies were predicted in the main oil pay Ⅴ1 for Member 1 of Liushagang Foramtion through reservoir inversion and by using prediction techniques.According to the predicted results,an infill well was located,drilled and put into development and production,resulting in good economic benefits.
