摘要
对惠民凹陷商河基山砂岩体低渗透储层的评价认识和开采工艺进行了探讨 ,结合储层特征开展了基山砂岩体测试曲线特征的研究 ,阐述各类曲线的特征表现及含油潜力。针对不同的曲线类型 ,提出了相应的压裂选井选层原则。现场实践表明 ,该套技术针对性强、效果显著 ,压裂有效率为 77.8%。
The paper discusses the evaluation and delivery technique for low permeability formation of sand body in Shanghe base mountain of Huimin sag.Combined with formation feature to study the testing curve of it,the properties of every type of curves and their bearing oil potential are also illustrated and according to different curves types,the principle for selecting well or zone to fracture is suggested.Field application reveals that this set of technology has a high pertinence and reaches a good result,and fracture effectiveness is 77.8%.
