煤层气井煤粉运移的控制,能够确保煤层气井的产量得以提升,对于合理安排排采作业有着重要的影响。煤层气井煤粉运移及控制问题,要注重对煤岩通道的动力学和运动学的把握,结合煤粉流体运移的情况,把握运移规律,以满足排采作业的实际需要。文章在对相关问题研究过程中,注重对煤粉的运营情况进行把握,借助于煤粉运移力学模型,把握煤粉运移临界速度,从而为煤层气井煤粉的控制问题予以有效把握。
The control of CBM migration in coalbed methane wells can enhance the production of CBM wells and has an important impact on the rational arrangement of extraction operations. In coalbed methane well, the problem of pulverized coal transportation and control should pay attention to grasping the dynamics and kinematics of coal and rock channel. Combining with the movement of pulverized coal, the law of migration is grasped to meet the actual needs of the operation. In the process of research on related issues, the paper focuses on the operation of pulverized coal, grasps the critical velocity of pulverized coal transportation by means of coal transport mechanics model, and thus effectively controls the pulverized coal in coalbed methane well.
