1results about How to "Simple and reliable measurement method" patented technology

The application provides a device and method for hydraulic pressure measurement while drilling, and belongs to the technical field of drilling water gushing pressure measurement. The device comprises an inlet and outlet port allowing fluid to enter and exit, a flow test chamber connected with the inlet and outlet port, a sealing measurement unit for sealing the inlet and outlet port and measuring the drilling water gushing pressure, a packer for closing the drilling, a hydraulic control unit for controlling the packer to close or open the drilling, a piston and a pushing ring. The application can measure the drilling water gushing pressure and fluid flow at different positions in real time by controlling the closing or opening of the drilling in real time, and the redundant actions of pulling out the drill and replacing the drill collar are omitted, so that the work efficiency is greatly improved.
