低渗透油田压力控制的方法及效果

METHODS AND EFFECTIVENESS OF CONTROLLING THE PRESSURE IN LOW PER-MEABLE RESERVOIRS

根据低渗透油田储层物性较差、压力传导慢的特征,本文从注采系统整体性出发,研究压力系统的控制机理、控制方法和控制范围。结合大庆外围油由的实例,通过压力控制,达到了注采系统的平衡协调,延长了采油系统的稳产过程,提高了低渗透油田的开发效益。

<ABSTRACT> Since the physical property of low permeable reservoirs is poor and conductivi- ty of pressure is slow. this paper studies the controlling mechanism, controlling method and controlling range of pressure system in consideration of the injection-production sys- tem. Taking an oilfield outside of Daqing oilfield as an example, by pressure controlling, the injection withdrawal balance is achieved.
