贵州省煤层气地质资源量十分丰富，二叠系上统龙潭组及长兴组为织金地区主要含煤层地层。近几年随着勘探开发的逐步推进，文家坝区块煤层气产气量取得较大成果。本文以文家坝区块高产煤层气井储层改造工艺技术为研究，建立适用于区块的压裂改造工艺体系；基于该区块煤储层特征研究，明确岩石力学特征、孔渗条件以及煤储层含气性，优化压裂地质选层，针对煤层多而薄、埋藏较浅的特点，形成适合多煤层“分段压裂、多层动用”压裂工艺技术，大规模压裂改造，增大SRV，保障产气效果，力争区块煤层气实现增储上产。

The geological resources of coalbed methane in Guizhou Province are very abundant. The Upper Permian Longtan Formation and Changxing Formation are the main coal-bearing strata in Zhijin area. In recent years, with the gradual advancement of exploration and development, coalbed methane production in Wenjiaba block achieved great results. In this paper, the reservoir reconstruction technology of high-yield coalbed methane wells in Wenjiaba block was studied, and the fracturing reconstruction process system suitable for the block was established. Based on the study of coal reservoir characteristics in this block, the rock mechanics characteristics, porosity and permeability conditions and gas content of coal reservoir were clarified, and the fracturing geological layer selection was optimized. In view of the characteristics of many and thin coal seams and shallow burial, a fracturing technology suitable for multi-seam ' staged fracturing and multi-layer production ' was formed, large-scale fracturing transformation was carried out to increase the SRV, ensure the gas production effect, and strive to increase the storage and production of coalbed methane in the block.
