面对油气资源的日益匮乏,以及经济发展对油气能源的需求。油气资源的供求矛盾日益突出,如何有效的提高油气采收率的问题受到越来越多学者的关注。传统的压裂、表面活性剂驱、注气驱、聚合物驱等方式虽在一定程度上提高了原油的采收率,但储层的非均质性导致仍有大量油气资源滞留在孔隙喉道中。为有效的对这一部分油气资源进行开发,本文对时移地震技术进行了研究。结果表明,在满足一定储层条件、开采条件的基础上,时移地震技术可以对储层孔隙喉道中的流体进行有效的监测,为调整油气藏开发方案提供有利的依据,进而提高原油采收率[1]。
Faced with the growing shortage of oil and gas resources, as well as the economic development of oil and gas energy needs. The contradiction between supply and demand of oil and gas resources has become increasingly prominent. How to effectively improve oil and gas recovery has drawn more and more attention from scholars. Traditional methods such as fracturing, surfactant flooding, gas-flooding and polymer flooding improve the oil recovery to a certain degree, but the reservoir heterogeneity still causes a large amount of oil and gas resources to remain in the pore throat Road. In order to effectively develop this part of the oil and gas resources, this paper studies the time-shifted seismic technology. The results show that on the basis of meeting certain reservoir conditions and mining conditions, the time-lapse seismic technique can effectively monitor the fluid in the pore throat of the reservoir and provide a favorable basis for adjusting the reservoir development plan, thereby enhancing the recovery of crude oil Rate [1].
