气藏动态储量计算与评价是气藏开发调整的前提和依据。基于常用计算气藏动态储量的单井集合法受到资料和生产时间等因素的限制,在实际应用中没有充分考虑井间干扰对计算结果的影响。针对各井投产时间不同造成的井间干扰并结合川东沙坪场石炭系气藏的实际情况,在物质平衡法的应用中进行改进。与传统物质平衡法单井集合比较,该方法消除了井间干扰造成的储量叠加问题,能够更准确地计算动态储量。
The calculation and evaluation of dynamic reserves of gas reservoirs are prerequisites and basis for the development and adjustment of gas reservoirs. The common well collection method based on the commonly used dynamic reserves of gas reservoirs is limited by the factors such as data and production time. In practice, the influence of crosswell interference on the calculation results is not fully considered. In view of the inter-well interference caused by the different production time of wells and the actual situation of Carboniferous gas reservoirs in Shapingchang area, the improvement is made in the application of the material balance method. Compared with traditional wellbore single well set, this method eliminates the problem of superposition of reserves caused by interwell crosstalk and can calculate dynamic reserves more accurately.
