由于地质条件的复杂性,导致对该区地应力方向的认识、裂缝分布规律研究存在较大的难度,影响了油井的压裂设计、井网部署。本研究主要从测井新技术应用的角度出发,利用微电阻率扫描成像测井技术能够识别地层裂缝方向和地应力方向,进而利用研究区块最大主应力方向与井网部署之间的关系,利用上述方法所得到地应力方向合理部署注水开发井网,降低油层水淹程度。研究结果属于前缘、攻关的新技术,该成果对后期井网部署和开发井压裂设计将提供一定的依据。
Due to the complexity of geological conditions, it is very difficult to study the laws of geostress direction and fracture distribution in this area, affecting the well fracturing design and well pattern deployment. Based on the application of new logging technology, this study can identify the direction and direction of formation fracture using the micro-resistivity scanning imaging logging technology. Based on the study of the relationship between the direction of maximum principal stress of the block and well pattern deployment, Utilizing the direction of the stress obtained by the above method, the well pattern of water injection and development can be reasonably deployed to reduce the degree of water flooding. The research results belong to the new technology of leading edge and tackling problems, and the results will provide some evidences for well pattern deployment and well fracturing design in the later period.
