稠油具有高粘度、密度大、高凝固点、高含蜡、流动性差等特性,中国在50年代就有发现,60年代进行过小型热采试验,因为稠油的特性,常规的技术难以经济有效的开发。本文主要介绍目前国内的稠油开采技术及现状,并提出未来稠油油藏热采的发展方向。
Heavy oil has the characteristics of high viscosity, high density, high freezing point, high wax content and poor fluidity. China discovered it in the 1950s and conducted small-scale thermal recovery tests in the 1960s. Because of the characteristics of heavy oil, conventional technologies are not economically effective Development. This paper mainly introduces the current heavy oil recovery technology and its status quo in China, and proposes the future development of heavy oil reservoir thermal recovery.
