煤层气年度配产方法研究

Research on Production Proration Methods of CBM Wells

研究准确合理的煤层气年度配方法,对于指导油气开发企业生产和后续开发有至关重要的作用。本文对目前适用煤层气的五种配产方法进行研究,从研究方法思路、适用条件、主要特点和存在优缺点等方面分别对五种配产方法进行详细剖析。不同条件下的区块应选择其适应的一种主要配产方法,对同一个区块,应该同时使用多种配产方法进行计算预测,相互对比,印证生产运行指标可行性。通过实际的应用,对预测结果进行验证,误差较小。

The research on the appropriate method of production proration for CBM wells is very important, which can provide guidance for an oilfield company＇ s production and subsequent development. The paper respectively studies and analyzes the five production proration methods which are fit for CBM currently, from the aspects of research methods and thoughts, applicability conditions, characteristics and merits and drawbacks. The main method which is fit for blocks in different situations should be chosen, and various methods should be used for calculation at the same time in the same blocks. The results could be used for comparison and to verify the data feasible. After the practical application and confirmation, the error is acceptability.
