难动用石油储量经济有效动用的边界条件研究

Study on critical conditions of economic development of difficult-to-recover reserves

在目前高油价形势下，将难动用储量变为经济可动用储量，对确保石油产量的稳定和增长，缓解国内石油资源的供需矛盾．具有重要意义。结合难动用储量的形成原因和特征分析，研究了江苏油田不同油价、不同油藏深度和不同递减率下的单井初始日产油界限和单位经营成本界限的变化规律，并绘制出了相应的边界条件图版，可以为实用的开发技术与经营管理技术的选择提供直观指导，从而不断提高单井产量和降低生产经营成本，实现难动用储量的经济有效动用。

On advantage conditions of high oil price, it is highly significant to turn difficult-to-recover reserves to profitable recoverable-reserves, which will ensure the oil production stabilizing or increasing, and will help to reduce the conflict between petroleum market supply and demand in our country. With the study of forming reason and character analysis of difficult-to-recover reserves, it analyses the critical conditions of individual-well initial production and critical operating cost under the conditions of different oil prices, different well depths and different initial individual-well production declining rate, which will guide the economic development of difficult-to-recover reserves.
