低渗透油气藏压裂返排液处理技术研究

Study of the Processing Technology for Low-permeability Oil and Gas Reservoir Fracturing Flowback Fluid

在低渗透油藏以及非常规油气藏的开发过程中,压裂技术可以对油气层的渗透能力起到改善作用。在一些老区油井挖潜以及新井试油的过程中,压裂都是十分普遍的一种技术手段。此外,在对非常规油气开发的过程中,对页岩气开发的过程中,都能采用这一技术,因此压裂技术的应用是十分广泛的。压裂返排液中的成分相对复杂,其中还含有一些污染物,如果不能对其进行有效的处理,那么对区域环境造成的污染将十分严重。针对这一情况,本文主要介绍了压裂返排液的处理技术,希望能够对今后的发展带来一定的帮助,更好的实现对油气田的污水处理。

In development process of low permeability reservoirs and the unconventional oil and gas reservoirs, the fracturing technology can improve the penetration ability of oil and gas layer. In the process of oil wells potentialities exploitation and new well oil testing in some old areas, fracturing is one popular technical means. In addition, in the process of unconventional oil and gas development and shale gas development,this technology is adopt ed, so the application of the fracturing technology is very extensive. The composition of fracturing flowback fluid is relatively complex, and it also contains some contaminants, if no effective processing is taken on it, then the pollution to the regional environmental will be very serious. In order to solve this situation, this article mainly introduces the processing technology of fracturing flowback fluid hoping to bring certain help to the future development and better realize the sewage treatment for oil and gas field.
