摘要

摘要: 目前国内外煤岩气层损害评价尚缺少统一的评价标准与指标。基于煤岩气层特点，分析了煤岩气层损害类型与机理，归纳了国内外分别从煤岩气层解吸性能、扩散性能和渗流性能进行评价的单一环节损害评价方法，分析各评价方法的优缺点及其适用条件。应力敏感、固相侵入与堵塞、聚合物吸附滞留、碱敏、煤粉运移堵塞是煤岩气层主要损害类型；煤岩气层损害既影响煤层排水，也影响煤层气产出，而煤层排水能力也影响煤层气产出；煤层气单一传质过程储层损害评价不全面，亟待建立单一传质过程结合多尺度传质过程的煤岩储层损害评价方法，但渗透能力评价仍然是关键，同时要考虑具有吸附气条件下水相渗流能力的损害评价。

Abstract: Coalbed methane (CBM) has great reserves in the world, and thus has great development potential. Unlike the production of conventional oil and gas, there still have no methods and performance parameters for evaluating damages caused to CBM-bearing formations. In this paper, based on the characteristics of coalbed gas formations, the types and mechanisms of formation damages are analyzed, and single-parameter evaluation methods presently used worldwide are summarized. These methods have been used to evaluate the damages caused to coalbeds with a single parameter, such as the desorptivity, diffusivity and filtration performance, respectively. The advantages and disadvantages, and the applicability of each method are also analyzed. The main damages to coalbed include stress-induced damage, solids invasion into and block of fractures in coalbed, retention of adsorbed polymer molecules, alkalinity-induced damage, and damage caused by migration and block of coal powders etc. Formation damage to coalbed not only affects water drainage, it also affects gas production, and the water draining ability of coalbed also affects gas production. Coalbed damage evaluation with measuring of single-process mass transfer is not an all-round method, and a method combining single-process mass transfer and the multiple-process mass transfer is urgently needed. Nonetheless, the evaluation of the coalbed permeability is the key to a method. Damage to the flow of water in coalbed with gas adsorption is another factor that should be considered in designing the evaluation method.
