FIELD: oil and gas production.
SUBSTANCE: invention refers to oil production, notably, to process of boring wells and is designed for automatic regulation of bottom-hole pressure of drilling agent and to maintaining it at level of reservoir pressure. The installation is equipped with a boring pump with a regulating drive, with a bottom-hole pressure sensor, with a communication channel, with a receiver, with a control block and with a master of forecast bottom-hole pressure. Additionally the installation is equipped with a correcting link and an integrating block; also the control block is connected to the input of the integrating block, the output of the integrating block is connected with the input of the correcting link, while an output signal from the correcting link is fed to the input of the regulating drive of the boring pump.
EFFECT: upgraded accuracy and reduced time of regulation of bottom-hole pressure of drilling agent.
