多煤层区煤层气开发优选评价体系分析
发布时间：2018-10-15 14:07
【摘要】：多煤层区有利区优选包括平面区段优选和垂向层段优选2个方面,针对现有煤层气评价体系难以适应多煤层区多层合采开发模式的不足,基于前期研究成果及目标区客观实际,提出了针对多煤层区的"基于地质模型的分层分区"平面优选方法和基于叠置含气系统理论的"主地质参数权重优选+数值模拟产能最优化"垂向优选方法。研究表明,地质建模和叠置含气系统理论是区别于单一煤层区煤层气开发优选评价的2个重要理论基础。同时,多煤层区煤层气开发优选研究重点应集中在煤储层参数反演技术及精细化描述、优选体系影响因素及主控因素研究、优选体系评价方法差异性分析及地质建模与数值模拟软件的应用4个方面。
[Abstract]:The optimal selection of favorable areas in multi-coal seam area includes two aspects: plane section optimization and vertical seam section optimization. In view of the shortcomings of the existing coal-bed methane evaluation system, it is difficult to adapt to the development model of multi-seam zone and multi-layer combined mining, based on the previous research results and the objective reality of the target area. Based on the theory of superimposed gas-bearing system, the method of "stratified zoning based on geological model" and "optimization of productivity of numerical simulation of main geological parameter weight" are proposed for multi-coal seam area. The study shows that geological modeling and superimposed gas system theory are two important theoretical bases for optimal selection and evaluation of coalbed methane development in a single coal seam area. At the same time, the research emphasis of coalbed methane development and optimization in multi-coal seam area should be focused on the inversion technology and fine description of coal reservoir parameters, the influence factors and the main control factors of the optimal separation system. The difference analysis of the evaluation method and the application of geological modeling and numerical simulation software are discussed.
