SIMULATION EXPERIMENTS OF KARSTIC WATER IN RENQIU OILFIELD

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.
