低渗油层层内爆炸研究与应用

Research and application of the In-fracture Explosive Technology in Low Permeability Reservoirs

我国低渗、特低渗油田逐年增多,过去的水力压裂技术已经不能满足当前需要。本文主要介绍了层内爆炸技术的几项重点内容及其特点,指出了利用爆炸压裂与水力压裂联作来进行油气田改造,效果显著。

In China,low-permeability and ultra low-permeability oilfields have been increasingly developed year by year;conventional hydraulic fracturing technologies can no longer meet the demand at the present.In this paper,the mechanism and characteristics of the in-fracture explosive technology were introduced.It’s pointed out that the combination of the in-fracture explosive fracturing with hydraulic fracturing to carry out the oilfield transformation can obtain significant effect.
