摘要: 板桥油气田内已发现的凝析油气藏共28个,大部分面积和储量较小,而且分布零散。其中已有27个凝析气藏采用消耗压力的方式开采,截止到1990年12月底,已先后有15个凝析气藏无生产能力。对己开发凝析油气藏开发全过程的分析研究,初步掌握了它们的开发特点,并从中找出了影响油气采收率的因素。通过数值模拟对开发方式的研究,以及现场排液采气的工艺试验和推广,初步摸索出一套提高油气采收率的方法和途径。

Abstract: A total of 28 condensate oil and gas reservoifs have been found in Bangqiao oil and gasfield.The area and reserves of these reservoirs are small. Among them, 27 condensate gasreservoirs have already been recovered by depletion. Up to Dec. 1990, 15 gas reservoirs havelost their productivity. Through analyzing and studying the whole process of the oil and gasreservoir development, all the characteristics have been understood,thus,the factors whichaffect oil and gas recovery efficiency have also been studied.Numerical simulation and technology of unloading gas well are used to give preliminary ways to improve the oil and gas recovery efficiency.
