| 摘 要： | 我国具有丰富的低渗透油气资源,压裂酸化改造是提高低渗透油气藏开采效果的重要手段,而地层破裂是储层压裂酸化改造成功的关键。在低渗透储层的改造过程中,由于储层段埋藏深、构造应力异常、泥质含量高等原因,某些井地层破裂压力异常高,导致了施工失败。本文以碳酸盐岩储层为研究对象,通过对碳酸盐岩岩石力学强度的本质分析,综述了岩石的矿物组成、结构特征、构造、水或者化学溶液作用以及缺陷对碳酸盐岩岩石力学性质的影响。为酸处理降低岩石力学强度,从而降低地层破裂压力提供了重要理论依据。 |

| Abstract: | Our country has aboundance low permeability oil and gas resources, fracture acidizing plays a great role in enhancing production of oil and gas reservoir, the formation break is the key of it. Due to deep burial and abnormal tectonics stress,high shale content and particularly high breakdown pressure, the reformation failed. The paper analyzed essentially the carbonate rock mechanical strength, summarized the impact of mineral production,structural feature, constitute, water or chemical fluid action and fault on the carbonate rock mechanics. Supplied the significant foundation for acidizing lowering rock mechanical strength to lower the breakdown pressure. |
| Keywords: | acid treatment survey low permeability fracture acidizing high breakdown pressure |
