| 摘 要： | 从水力破裂缝形成机理和条件入手，分析水力破裂缝形成的潜在原因。以某异常高压油田为例，通过对构造演化史进行研究，确定了该油田具有水力破裂缝形成的条件。对岩心照片观察结果表明，该油田存在水力破裂缝，其形成方式主要分为: 重新开启缝、后期延伸缝及新形成缝; 这三类裂缝主要分布在渗透率较低的隔夹层，形成的水力破裂缝可大大改善储层渗流能力，形成高产储层。

| Abstract: | The paper analyzed the potential formation reasons of hydraulic fractures based on the formation mechanism and conditions of fractures.Taken an abnormal high pressure reservoir as example,the formation condition of hydraulic fractures are confirmed through theoretical research and analysis to tectonic evolution history.The core photos showed there are existed fractures in this oil field which could be classified into three types: re-open fracture,extend fracture and new fracture.All those fractures could gr... |
