| 摘 要： | 大型溶洞是塔里木油田缝洞型储层的重要储集空间,其成因复杂,结构相对简单,分布极不规律,是构成复杂缝洞型油藏的一个基础.目前该类油藏的开采方式主要依靠弹性能量开采.为了研究溶洞弹性开采自喷期阶段的井底压力和产量的变化规律,本文对其进行了简单的理论分析,又进行了模拟油和高黏度原油的物理模拟实验,理论分析结果和模拟实验结果能够很好吻合.结果表明,井底压力随开采时间星指数递减趋势,递减指数与井口产量控制和溶洞内油水体积比、压缩系数有关,油井产量随开采时间也呈指数递减趋势;累积产量与累积压降曲线呈直线关系,其斜率的物理意义是单位生产压差下的累计产液量,大小只与溶洞内油水体积比和压缩系数有关,由此可估算溶洞体积范围.

| Abstract: | The large caves are important storage space in fractured reservoirs in Tarim oilfield.The formation mechanism of the caves is very complex,but their structure is relatively simple.The large caves are the foundations of a complex vuggy reservoir.Currently the main method of exploitation of such reservoirs is based on mining.In order to study the variation of the bottom hole pressure and the production rate under the elastic mining conditions,a simple theoretical analysis and some physical simulation experime... |
