| 摘 要： | 迪那2气田古近系苏维依组及库姆格列木群油气层属于低孔—低渗裂缝性砂岩储层,有效评价储层中裂缝的发育特征对认识开发中存在的层间矛盾及优化井网部署具有重要意义。为预测迪那2气田古近系苏维依组及库姆格列木群储层裂缝分布情况,采用岩心、测井裂缝解释成果等资料,确定裂缝成因类型及影响因素。选择构造主曲率、屈曲薄板法及构造滤波法分别对迪那2气田构造裂缝分布进行评价预测,在此基础上通过对3种方法的综合分析,构建裂缝综合评价因子法。前3种方法的评价结果与成像测井资料解释成果的吻合率在44%～56%之间,而综合评价因子法达到78%,明显提高裂缝分布评价的精度,说明这种综合评价因子法是进行裂缝分布预测的有效手段。分析认为研究区裂缝主要发育在靠近断裂带、构造轴线以及局部高点变形较大的部位。

| Abstract: | E2-3s Formation reservoir is characterized as low porosity and low permeability in the Dina2 gas field.The effective evaluation of fracture-growing situation is significant for knowing the interlamination inconsistence and optimizing well network.In order to predict fracture distribution of reservoir in E2-3s formation and E1-2km group in the Dina2 gas field,we use the core and fracture image logging interpretation data to understand the genetic type of fracture and controlling factors.We use the tectonic p... |
