Wellhead connection skid is mainly used for the output media transportation, production dynamic monitoring and automatic control of various types of oil and gas wellhead in oil field. With the equipped temperature change, pressure change, combustible gas (or harmful gas) alarm device, electric control valve and other devices, it can effectively monitor and manage the production of oil and gas wells by collecting production data on site in real time, and also carries out all-day-around monitoring for the combustible and harmful gas within the wellhead, and send timely abnormal warning, automatically closes the emergency block valve remotely to achieve the goal of improving the intelligence and refinement of oil field production management. It will effectively improve site management and productivity, prevent the harmful and dangerous gas leakage caused by environmental pollution and the hidden dangers caused by the flammable gases with a concentration exceeding the permissible standard, as well as protecting the environment effectively.

Structural composition

The main body of the device is composed of seamless pipe, seamless pipe fitting, welding neck flange, steel gate valve, bimetal thermometer, pressure transmitter and skid mounted base, etc. The electrical part is equipped with wireless temperature change, wireless pressure change, combustible gas (or harmful gas) alarm device, electric control valve, etc.

Functional features

Real-time, all-day-around acquisition and transmission of production parameters such as temperature and pressure of wellhead production medium, and guarantee smooth operation of production.

Install combustible gas (or harmful gas) alarm, electric control valve and other automatic control devices, alarm in time and handle automatically in case of danger.

With skid mounted design, it is conducive to overall planning of ground construction scheme.

Adopt advanced Lora technology to realize wireless communication, has the advantages of strong anti-interference, good privacy, long communication distance and low power consumption.

Adopt advanced digital measuring instrument to improve management level.
