	<span style=\"line-height:1.5;\">可改造性是指油气储层能够被有效改造的性质，是非常规油气开采中的重要参数。对于煤系“三气”合采储层来说，目前常用到的方法是将不同储层单独评价，然后通过叠加得到“三气”合采储层可改造性优选区，这种方法缺少储层组合观念。为此，我们将多种可采储层划分为不同的产层组，并通过一定的方法将各储层参数转化为产层组参数。根据前期研究确定脆性指数、石英含量、孔隙度、TOC、渗透率、含气量、水平应力差、断裂韧性、黏土矿物含量、含水饱和度为影响产层组可改造性的因素，采用层次分析法建立层次结构，利用判断矩阵得到各参数权重，建立了产层组可改造性评价模型并应用于鄂尔多斯盆地东缘临兴区块。采用该模型得到临兴区块西北部是A型产层组可改造性最好的地区，其次是区块南部和东南部，而在区块东北部和西部的A型产层组可改造性较差。<br />
Reconstruction refers to the nature of oil and gas reservoirs that can be effectively modified, and is an important parameter in unconventional oil and gas production. For coal-bearing “three gases” combined production reservoirs, the currently commonly used method is to evaluate different reservoirs separately, and then obtain the optimal reformability area of the “three gases” combined production reservoirs by superposition. This method lacks storage Layer combination concept. To this end, we divide a variety of recoverable reservoirs into different production groups, and transform each reservoir parameter into a production group parameter by a certain method. According to the previous research, the brittleness index, quartz content, porosity, TOC, permea-bility, gas content, horizontal stress difference, fracture toughness, clay mineral content, water saturation are determined as factors that affect the reformability of the formation group. Hierar-chical structure, using the judgment matrix to get the weights of each parameter, and establish the evaluation model of the productivity of the formation group and apply it to the Linxing block on the eastern edge of the Ordos Basin. Using this model, the northwestern part of the Linxing block is the area where the A-type formation can be transformed most, followed by the south and southeast of the block. In the northeast and west of the block, the type A formation strata is poorly remodelable.</span><span style=\"line-height:1.5;\"></span>
