复杂裂缝压裂优化研究及应用

Research and Application of Optimum Fracturing Measures for Complicated Ruptures

压裂过程中能产生复杂裂缝是近年来对压裂技术的新认识,对于易产生复杂裂缝的地层,必须充分利用复杂裂缝来扩大泄油面积,增大改造体积。本文探索了复杂裂缝的形成条件,并针对易产生复杂裂缝的油藏进行了工艺优化,现场试验表明该工艺技术是可行的,压后效果表明该技术能够提高油井的产能。

The fracturing technology has been understood in a new way recently, that is, complicated ruptures can be produced during the fracturing process. So, the drainage area and the reconstruction volume must be expanded and enlarged on the stratums vulnerable to generate complicated ruptures by fully using the complicated ruptures. The paper has probed into the forming conditions of such ruptures and technically optimized the oil reservoirs likely to cause these ruptures. The field test shows that this technology is feasible and the fracturing effect indicates that it is capable of enhancing oil well productivity.
