沁水盆地煤层气田地面集输系统优化

Surface gathering technology used in the CBM field of Qinshui Basin

为进一步研究沁水盆地煤层气田地面集输优化技术,实现"十三五"期间的高效开发,基于统计分析理论,利用煤层气田采集气管网运行大数据分析平台,挖掘技术难点,思考研究方向,着力解决和处理系统建设、运行过程中出现的"三难"(征地难、建站难、布管难),"三高"(投资高、闲置高、能耗高),采出水"三差异"(水质差异、标准差异、产水差异)等问题及矛盾。研究表明:改变地面建设模式,更新设计理念,实现地下与地上一体化建设、满足需求的可拓可控式集输工艺设计,是解决当前集输系统问题和矛盾的关键。该研究成果对沁水盆地煤层气田的新区块开发建设具有十分重要的工程指导意义。

To study further the surface gathering optimization and simplification technologies suitable for the coalbed methane(CBM) field in the Qinshui Basin and realize its efficient development in the period of 13 th Five-Year Plan, a series of analysis was conducted based on the statistical analysis theory in the big data analysis platform of CBM production and gathering pipe network operation. Technical difficulties were mined, the research direction was analyzed, and efforts were put forth to solve and deal with the problems and contradictions that occurred in the process of system construction and operation, e.g. "three difficulties"(land requisition difficulty, station construction difficulty, and pipeline arrangement difficulty), "three highs"(high investment, high idle rate, high energy consumption), and "three differences" of produced water(water quality difference, standard difference, water production difference). It is indicated that the key to solve the problems and contradiction of current gathering systems is to change the ground construction mode and update the design concept so as to realize the integrated ground-underground construction and conduct the flexible, expandable and controllable gathering process design. The research results are of important instruction significance to the development and construction of new blocks in the CBM field of Qinshui Basin.
