Example Embodiment

[0016] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0017] Reference figure 1 The structure of the remote control system for the rotary cement head of the present invention is composed of three parts: an electric control mechanism 3, a wireless remote control 4, and an air control mechanism 5. The electric control mechanism 3 and the air control mechanism 5 are arranged on the cement head body 2 of the cement head 1. On the outer surface, the wireless remote control 4 is set at the operating position of the rear personnel. The wireless remote control 4 communicates with the electric control mechanism 3 through radio waves. The electric control mechanism 3 communicates with the air control mechanism 5 through cables. The air control mechanism 5 completes the cement head All functions;

[0018] The structure of the electronic control mechanism 3 is to include a separate power supply 18 and a transceiver module 19. ...

Abstract

The invention discloses a remote control system for a swivel cementing head. The remote control system for the swivel cementing head comprises an electric mechanism, a wireless remote controller and a pneumatic mechanism; the electric mechanisms and the pneumatic mechanism are arranged on the outer surface of a swivel cementing head body; the wireless remote controller is arranged at an operation position of a rear person and communicates with the electric mechanism through radio wave; the electric mechanism communicates with the pneumatic mechanism through a cable. According to the remote control system for the swivel cementing head, the pneumatic mechanism can be connected and the electric mechanism can be started when operating the swivel cementing head, then a worker can operate through the wireless remote controller according to the requirement, and a wireless transceiver can transmit an instruction to the electric mechanism and the pneumatic mechanism, so as to achieve the corresponding operation; the remote control system works through radio wave achieve the unmanned operation of an explosion proof region, and therefore, the labor cost is saved, and moreover, the working safety is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of cementing, well completion and workover operation tools for oil and gas fields, and is applicable to the development and operation of oil and natural gas and unconventional energy fields, in particular to a remote control system for a rotary cement head. Background technique [0002] The cement head is a high-pressure wellhead device with built-in rubber plugs in cementing operations, and has the functions of plugging, alternate manifolds, and valve connections. The conventional cement head has a simple structure, and the operator rotates the valve to complete the cementing operation. There are two types of existing conventional cement heads: [0003] One of them can only realize fixed operations such as plug injection and cement injection, and cannot add pre-fluid before the plug or change the operation sequence according to actual working conditions; although the other can realize the above-mentioned o...
