| 摘 要： | 在调研注空气技术原理及其油藏适宜度的基础上,针对国内某低渗透砂岩油藏X区块地质特点,对区块进行注空气适应性评价,初步明确油藏开发方式为注空气开发。然后,开展室内油水和油气相渗透实验,应用油水及油气渗流理论和油藏工程及气藏工程方法,在分析采油指数与吸气指数、油层破裂压力和注气能力的基础上,确定了低渗透油藏M区块的合理注气压力和注气量。最后采用数值模拟技术对5种开发方案进行预测对比,得出注气比注水开发效果好,进一步对M区块注空气开发进行验证,并筛选出最优开发方案。笔者从注空气技术对油藏的筛选标准、注气能力分析、数值模拟验证等一系列方法对X油藏M区块进行注空气适应性分析,为类似油藏注空气开发提供了有效的方法。
