Abstract

The invention discloses a remote control cement head, comprising a hydraulic control cement head, a remote control system and a power source, the power source is connected with the remote control system; the remote control system is connected with the hydraulic control cement head; the hydraulic control cement head is composed of a cement head main body, a hydraulic plug valve, a hydraulic stop pin, an indicator mechanism, and a circulating manifold, wherein the cement head main body and the circulating manifold are vertically arranged in parallel; one end of the hydraulic plug valve is connected with the circulating manifold; the other end of the hydraulic plug valve is connected with the cement head main body, the hydraulic stop pin is connected with the cement head main body and arranged on the opposite face of the hydraulic plug valve, the indicator mechanism is arranged on the cement head main body, and the indicator mechanism, the hydraulic stop pin and the hydraulic plug valve are not repeatedly arranged on the side face of the cement head body. The remote control cement head has the advantages that through remote operation of well cementation cement operation, safety of personnel is guaranteed, and operation risks are reduced.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploitation equipment, in particular to a remote control cement head. Background technique [0002] With the development of drilling technology from shallow wells and medium-deep wells to deep wells and ultra-deep wells, the cementing operation environment has become more and more complex, the length of the cementing string has become longer and longer, the working pressure of the cement head has gradually increased, and the operation is difficult. Also increase correspondingly, the danger of construction personnel is also increasing during cementing operation. [0003] For this reason, there is an urgent need for a cement head that can be remotely controlled to realize cementing operations, ensure the quality of cementing, and improve production efficiency. Contents of the invention [0004] The purpose of the present invention overcomes the shortcomings of the prior art, and provides a r...
