The utility model discloses an emergency shut-off protection device for wellhead remote control adjustment, which is designed for the purpose of realizing the digital management of gas well switch operations in gas fields, improving labor efficiency and reducing operating costs. The wellhead adjustable emergency cut-off valve is arranged on the gas well pipeline Between the upper flow meter and the upstream oil pressure, connect the downstream oil pressure at the same time. The upstream oil pressure, downstream oil pressure, flow meter and adjustable emergency cut-off valve at the wellhead are all connected to the intelligent switch well controller, and the intelligent switch well controller is connected to the computer platform relying on the wireless transmission device. When the oil pressure behind the protection device exceeds or falls below the set pressure, the protection device can be automatically closed to realize automatic protective shut-in. Regardless of how high the upstream oil pressure is, the protection device can implement remote control and automatically adjust the opening of the well. The protection device can perform real-time and rapid remote control of automatic well opening and closing, and the remote control and manual control can be switched to each other, greatly improving labor efficiency, reducing labor intensity, reducing operating costs, and realizing digital management of gas well opening and closing in gas fields.
Description
Technical field
The utility model relates to a kind of well head and far controls adjusting emergency cut-off protective device, belongs to gas field gas well switch well operations technical field.
Background technology
Along with the exploitation of Soviet Union's Sulige gas field, the switch well operations of gas well is increasing, and particularly intermittently the increase of gas well makes the switch well operations of gas well very frequent, and workload is very large.At present, the well remote control switch technology of gas field field by using is without regulatory function, and the operation that can not drive a well still needs manually-operated, and workload is large and operation is untimely, and efficient is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of well head far to control and regulates the emergency cut-off protective device, and it can realize the digital management of gas field gas well switching operations, raises labour efficiency, and reduces running cost.
Concrete technical scheme of the present utility model is as follows:
Well head can be regulated urgent block valve and be located on the gas well pipeline between the flow meter and upstream oil pressure, and simultaneously, well head can be regulated urgent block valve and connect the downstream oil pressure.Upstream oil pressure, downstream oil pressure, flow are taken into account well head and can be regulated urgent block valve and all connect intelligent switch well controller, and intelligent switch well controller relies on radio transmitting device to connect computer platform.
When oil pressure behind this protective device surpasses or is lower than setting pressure, protective device energy autoshutdown, protection downstream line system realizes automatic protectiveness closing well.No matter how high the upstream oil pressure is, and this protective device all can be implemented automatic adjusting of Long-distance Control and drive a well.This protective device can carry out real-time Long-distance Control automatic switch well, and Long-distance Control and manual control can be switched mutually, significantly increase work efficiency, and reduce labour intensity, reduce running cost, realize the digital management of gas field gas well switch.
Description of drawings
Fig. 1 is that well head is far controlled the connection schematic diagram of adjusting emergency cut-off protective device on the gas well pipeline.
The specific embodiment
With reference to Fig. 1 embodiment of the present utility model is further specified:
Embodiment:
Well head can be regulated urgent block valve 1 and be located on the gas well pipeline between the flow meter 7 and upstream oil pressure 5, and simultaneously, well head can be regulated urgent block valve 1 and connect downstream oil pressure 6.Upstream oil pressure 5, downstream oil pressure 6, flow meter 7 and well head can be regulated urgent block valve 1 and all connect intelligent switch well controller 2, and intelligent switch well controller 2 relies on radio transmitting device 3 to connect computer platform 4.
When Long-distance Control drives a well, computer platform 4 relies on radio transmitting device 3, urgent block valve 1 forward and backward upstream oil pressure 5 and downstream oil pressure 6 be can regulate by 2 pairs of well heads of intelligent switch well controller and information gathering and intelligent comparison judgement carried out, and then control and regulate well head and can regulate urgent block valve 1 opening, when treating that upstream pressure is down to setting value, drive valve and open fully, realize that Long-distance Control drives a well.
During the Long-distance Control closing well, computer platform 4 relies on radio transmitting device 3, can regulate urgent block valve 1 by intelligent switch well controller 2 driving well heads and close, and realizes the Long-distance Control closing well.
During the self-shield closing well, downstream oil pressure after well head can be regulated urgent block valve 16 surpasses or when being lower than setting pressure, the valve autoshutdown, and protection downstream line system realizes the ultra under-pressure defencive function.
