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。
Studying accurate and reasonable coalbed gas annual allocation method is very important to guide the production and follow-up development of oil and gas development enterprises. In this paper, five kinds of allocation methods for CBM are studied. Five allocation methods are analyzed in detail from the aspects of research methods, applicable conditions, main characteristics and advantages and disadvantages. In different conditions, the block should be selected to adapt to a major allocation method, for the same block, should also use a variety of allocation method to calculate the forecast, compared with each other to confirm the feasibility of production operation indicators. Through the practical application, the prediction results are verified with less error.
