哈拉哈塘油田走滑断裂控藏研究——以RP8断裂为例

Study on the Reservoir Control of the Strike-slip Fault in Halahatang Oilfield and Its Application——By Taking RP8 Fault for Example

以RP8断裂为例,在走滑断裂斜列分段模式指导下,基于三维地震资料和断溶体研究思路对哈拉哈塘油田油藏进行了重新认识。对RP8断裂进行梳理,从南到北可以分为线性段、斜列段和马尾段3段样式,控制发育了3种类型油藏——线性断溶体油藏、斜列状断溶体油藏、半花状断溶体油藏,并对不同类型油藏在井位部署时的优选原则进行了研究。研究成果在哈拉哈塘油田进行了推广,取得了较好的应用效果,多口井获得了高产工业油气流,对实际生产具有重要指导意义。

In this paper,under the guidance of the segmentation mode of the strike-slip fault,based on the study of fractured reservoir control,the reservoir is re-recognized in Halahatang Oilfield.After the sorting out of RP8 Fault,it can be divided into three sections (linearity,diagonal and horsetail segments) from the south to the north.Three types of reservoirs,such as linear fault-solution reservoir,oblique fault-solution reservoir and half-flowered shape fault-solution reservoir,are controlled by the three sections.The optimized principles for well location deploying for different types of reservoirs are studied.The research results are popularized in Halahatang Oilfield and good application results are achieved.High-yield industrial oil and gas flow is obtained in many oil wells.It is of great significance for actual production.
