我国蕴藏着丰富的石油资源,其中高粘度、高比重原油性质的油田,分布很广,储量很大,据克拉玛依油田已开发区的统计,粘度(20℃时)大于一千厘泊,比重大于0.88的原油,占储量的三分之一。这种原油的经济价值高,利用一般开采方法不易开采出来。为了解决高粘度原油的开采问题,提高油田的采收率和采油速度,我局于五八年大跃进时期,开始了火烧油层这项新技术的试验。火烧油层是利用热力的作用,提高油层温度,降低原油粘度,增加其流动性,从而
Our country is rich in petroleum resources. Among them, the fields with high viscosity and high proportion of crude oil are widely distributed and have large reserves. According to the statistics of developed areas in Karamay, the viscosity (at 20 ℃) is more than 1000 centipoises, the proportion is greater than 0.88 of crude oil, accounting for one third of the reserves. The high economic value of this crude oil, using the general mining method is not easy to mined out. In order to solve the problem of high-viscosity crude oil recovery and increase oil recovery and recovery rate, our bureau started the experiment of burning the new oil layer during the Great Leap Forward period of five to eight years. Burning the oil layer is the use of the role of heat to increase the temperature of the oil layer to reduce the viscosity of crude oil to increase its liquidity and thus
