Document Type and Number:
WIPO Patent Application WO/2018/161577
Kind Code:
A1
Abstract:
A monitoring and control method utilized in coal reservoir fracking at a mining well, a device, and a monitoring and control apparatus. The method comprises: receiving a configuration of control parameters used to perform hydraulic fracturing on a coal reservoir (1), wherein the control parameters comprise a fluid pressure range, a fluid discharge range, and a sand ratio range; determining whether a value of a first pressure signal of a fluid in a pipe obtained by a pressure sensor (6) is within the fluid pressure range; and if so, adjusting the fluid discharge range and the sand ratio range in the control parameters to adjust a pressure of the fluid in the pipe, until completion of the fracking process. Also provided are a monitoring and control device and monitoring and control apparatus utilized in coal reservoir fracking at a mining well.
