在国内油气供需缺口日趋加大、石油进口依赖程度越来越高的今天,加大我国石油自给率具有非常重要的战略意义。而在我国石油储量中约有1/4为难动用储量,因而开发这类难动用储量将成为解决国家石油安全问题的重要砝码。 At a time when the gap between domestic oil and gas supply and demand is increasingly widening and the dependence on oil imports is getting higher and higher, increasing the self-sufficiency rate of petroleum in our country is of great strategic significance. About a quarter of the oil reserves in our country are difficult to use reserves, therefore, developing such difficult-to-use reserves will become an important weight for solving the national petroleum safety issue.
