边水凝析气藏型储气库多周期注采水侵量计算模型
Multi-cycle water influx calculation model of reconstructing gas storage in condensate gas reservoirs with edge water
摘要
Abstract
At present, there is difficulty for calculating the water influx caused by the complicated phase changes in recon-structing gas storage in condensate gas reservoirs with edge water. In view of the differences between the injection gas and the producing gas, considering the mixture of dry gas and condensate gas, retrograde condensation, edge water influx, the com-pressibility of rock and bound water and so on, the material balance formula was deduced based on the principle of mass con-servation. Subsequently, the calculation model of water influx and the calculation method of parameters were established. Combining with the production data of underground gas storage in China, the water influx was calculated and its influence factors and characteristics were analyzed. The results show that the calculation results of water influx accord with the variation of formation pressure in the period of injection and production conditions, and the cumulative water influx decreases with the amount of inventory increasing. With the injection of dry gas and the extraction of condensate gas by dry gas,the impact of retrograde condensation on the water influx of gas storage is minimized. The water influx obtained by the new model is in good agreement with the numerical simulation results.关键词
