| Abstract: |
| In view of the reservoir damage problems encountered in the development and production of shale gas, the authors described in detail the characteristics of shale gas reservoirs in Qinshui Basin from aspects of structural features, pore structure, temperature and pressure, formation water composition, Layer, the TOC, Ro, SEM, slice identification, whole rock analysis and gas content analysis of the rock samples, the potential water sensitivity, speed sensitivity and acid sensitivity of the reservoir are obtained. Considering the shale Reservoir permeability is low, and the development of microfractures is rich, the reservoirs will also have certain solid damage and stress sensitivity characteristics. During drilling and completion, attention should be paid to prevent these damages. |
