摘　　要：针对松滋油田复Ⅰ断块沙市组物性差,埋藏深,注采井网不完善,储层水敏性强,采用天然能量开发产量递减快,采出程度低等问题,开展了水、N2、CO_2等不同驱替介质的开发可行性评价,结果表明注CO_2效果最好。以油藏数值模拟为技术手段,优化和确定了CO_2吞吐和CO_2非混相驱的最佳条件和最佳注入参数,优选CO_2吞吐与CO_2间歇气驱两种方案,供生产单位根据实际情况选用。Aiming at such problems in Shashi formation as poor physical property, deep burial, imperfect injection-- production pattern, strong water sensitivity of reservoir, fast production decline with natural energy and lower recovery percentage, this paper evaluates development feasibility of various displacing medium including water, N2 and CO2, showing that CO2 has the best result. On the basis of numerical reservoir simulation, this paper ensures the best condition and injection parameter for CO2 huff and puff and CO2 immiscible displacement and optimizes two projects（CO2 huff and puff and interval CO2 gas drive） for the production unit to choose according to its actual situation.
