目前我国在低渗透油田开采过程中,传统以注水开发形式为主。由于注水开采技术成本高,并且经济效益矛盾突出,提高油气的开采率是油田开发企业最终目标。为此,探索更加经济型的开发方式,如何提升低渗透油田开采的技术水平是本文探究的新课题。笔者从低渗透油储层田的特征入手,阐述了一系列提高低渗透油田开采率的技术方法,如注气技术、微生物开采技术、化学驱技术等,从而适应低渗透油田未来的发展要求。
At present, China’s exploitation of low-permeability oil fields, the traditional form of water-based development. Due to the high cost of water injection technology and the obvious contradiction between economic benefits, it is the ultimate goal of oilfield development enterprises to increase the oil and gas recovery rate. Therefore, to explore a more economical mode of development and how to improve the technological level of low-permeability oilfield exploration is a new topic explored in this article. Starting with the characteristics of low-permeability oilfields, the author describes a series of technical methods to improve the exploitation rate of low-permeability oilfields, such as gas injection technology, microbial exploitation technology and chemical flooding technology to meet the future development requirements of low-permeability oilfields.
