| 摘 要： | 水力压裂技术是有效开发低渗透油气藏必不可少的主要技术措施，但经过水力压裂的油气井，在生产过程中由于种种原因可能导致水力裂缝失效。为此，文章较系统地研究讨论了重复压裂裂缝延伸方式及判断方法，分析了原有裂缝失效的可能原因，提出了重复压裂的系统评估技术正确评价裂缝当前状况，阐述了重复压裂的选井选层原则与方法和重复压裂裂缝延伸模拟方法。

| Abstract: | Repetitive fracturing is a very important measure for the oil and gas reservoirs which can′ t put into production until fracturing to improve the recovery rate. Attention is paid to the measure very much at home and abroad. The article discusses the fracture expanding way and identifying method for repetitive fracturing, analyzes the probable reasons why the precious fractures fail, proposes the systemic evaluation technology to estimate the resent status of the fractures for repetitive fracturing, and describes the principle and method to select wells and formations, and the way to stimulate the fracture expanding for repetitive fracturing. These points of view has major significance to guide and conduct repetitive fracturing. |
