摘要
Abstract
The different forms of fracturing fractures have a significant impact on the post pressing production capacity of coal seam gas.In order to clarify the impact of different fracture parameters on post pressing production capacity,based on the principle of water and electricity similarity,the experiment uses electrical methods to simulate the effects of fracture half length,modified volume,fracture angle,and fracture position on production capacity.The results show that the pressure drop of the reservoir increases with the increase of the half length of the fracture,and the corresponding usable range gradually increases,resulting in an increase in the steady-state production capacity of the horizontal well;the larger the comprehensive transformation factor of the reservoir,the higher the initial production;the production increases with the increase of fracture angle,and when the fracturing transformation area is perpendicular to the horizontal wellbore,the production of the volume fracturing horizontal well is the highest;the fracturing transformation zones at both ends contribute the most to the production of volume fracturing horizontal wells.关键词
