摘　　要：煤层气井采用的排采设备基于常规油气井的开采设备,在现场应用中存在诸多问题,影响了煤层气的开采效果。为了实现较高的开采效率,通过对煤层气井各排采方式的分析,结合模糊数学的理论知识,利用模糊综合评判法建立了煤层气排采方式评价模型,从技术因素和经济因素两方面对现场煤层气井的排采方式进行模糊评价并选出了最优的排采方式,结果表明所选方式符合现场所用设备,为煤层气排采工艺的优选提供了理论依据和技术方法。For coalbed gas wells,the water-drainage and gas-production facilities are very similar to those for conventional oil and gas wells.There are many problems,further affecting production effect of coalbed gas.In this study,every water-drainage and gas-production pattern is analyzed at first;and then,integrating with theory of fuzzy mathematics,a model to evaluate these patterns is established through fuzzy evaluation method;thirdly,fuzzy evaluation on in-situ patterns is carried out technologically and economically;finally,the optimum pattern is selected.Results show that the selected one is available.
