Performance Rule Prediction in Gas Production by Water Withdrawal for Water Drive Gas Reservoir

本文介绍了应用物质平衡法进行水驱气藏排水采气动态规律预测的方法。通过对中坝须二气藏在不同开采速度、不同排水方式、不同排水规模下三方面10个开发指标的预测,揭示了水驱气藏排水采气的动态规律,为排水采气方案的确定提供了理论依据和研究方法。

This paper introduces the performance rule prediction for water withdrawal in gas production in water drive gas reservoir, using the material balance method. Through the prediction of ten development indexes in three aspects including various recovery rates, various water withdrawal ways and various water withdrawal scales for Xu-2 gas reservoir of Zhongba gas field, the performance rules of water withdrawal in gas production in water drive gas reservoirs are revealed, providing the theory basis and investigation method for determining the plan of water withdrawal in gas production.
