摘要
对研究区泾河油田17井区长8油藏致密砂岩储层的水平井天然裂缝进行研究,利用录井井漏等资料对裂缝段进行标定,并通过生产动态资料进行验证;依据水平井裂缝的常规测井异常响应特征,提取裂缝的响应信息,建立了水平井天然裂缝综合判别模型。实例应用表明,该判别模型对裂缝段的识别率达到80.77%,满足了研究区内水平井裂缝段的解释要求,具有较好的应用效果。
The study on natural fracture response characteristics of horizontal wells in Chang-8 sandstone reservoir in well block-17 of Jinghe oilfield has been carried out.By using the well logging,leakage data,etc,the calibration on fracture member has been done and it has been verified through production dynamic data.According to abnormal response characteristics of the conventional logging in horizontal wells,the fracture response characteristics have been obtained and then the comprehensive discrimination model has been established.The application results indicate the recognition rate of this model can be up to 80.77%,which can meet the interpretation requirements of fracture member in horizontal wells in the study area and has a better application prospect.
