SIMULATION EXPERIMENTS OF KARSTIC WATER IN RENQIU OILFIELD
-
摘要: 根据任丘油田的地质条件和化学动力学原理,作者利用DF—05型高压釜对油田热水喀斯特的机理进行了模拟实验。通过实验作者认为,在CO2—油田水—碳酸盐岩的多相复杂体系中,岩石的溶蚀程度受岩石化学成分、油田水化学组合、温度、二氧化碳的分压、搅拌速度和反应时间等诸因素控制;在油田环境中,白云岩受油田热水的强烈溶蚀可形成良好的油气储集空间。Abstract: Based ont he geological condition and principle of chemical dynamics, the author simulated the karstification of thermal water in the oilfield, by using DF-05 Type autoclave. The author thinks that 1) there are several factors that control the corrosional degree of a rock: the chemical composition, chemical combination of oil field water, temperature, differential pressure of carbondioxide in the rock itself, and the agitating speed and reaction time etc; 2) in oil field environment, the dolomites subjected to strong corrosion of oil field water may form good hydrocarbon reservoirs.
