克拉玛依油田八区下乌尔禾组油藏裂缝识别方法

裂缝的识别与评价一直是油田开发储集层性质研究的难点, 以克拉玛依油田八区下乌尔禾组油藏为例, 采用岩心资料和EMI 成像资料的裂缝分析为基础, 描述了研究区各种类型的裂缝的基本特征; 进行了大量的常规测井资料的裂缝分析与标定, 建立了应用常规测井资料进行裂缝识别的模式; 通过研究区内实际井的处理和解释, 确定了单井裂缝类型、发育程度, 揭示了下乌尔禾组油藏中裂缝的空间分布。

Fracture Identification Method for Lower Wuerhe Reservoir of District No.8 in Karamay Oil Field

Fracture identification and evaluation are difficult to run in the research of reservoir quality in oilfield development. Based on the core data and EMI fracture analysis of Lower Wuerhe reservoir in District No.8 in Karamay oil field, the basic characteristics of various fractures in this area are described, numerous conventional well log data are analyzed and calibrated in terms of natural fractures, thus developing model for identification of the fractures by means of conventional well log data. By processing and interpretation of wells in this area, the types and developed extent of the fractures in single well are confirmed, the space distribution of the fractures in Lower Wuerhe reservoir is revealed.
