Problems solved by technology

At present, the on-site construction of the surface construction project of the Sulige gas field is limited by the climate and equipment. The construction period is long, the organization and coordination are difficult, and the area is large. During the daily production and operation of the gas well, the remote opening operation needs to be operated at the wellhead of each gas well. , t

Embodiment 1

[0016] Such as figure 1 Shown is a movable skid-mounted cluster well site integrated device, which includes skid-mounted equipment interface 1, switch well control valve 2, emergency shut-off valve 3, two-phase flowmeter 4, single well shut-off valve 5. Flow control valve 6. Differential pressure sealed power generation device 7. General shut-off valve 8. Skid-mounted equipment to downstream pipeline interface 9. Natural gas manifold 10. Gas from the gas tree first enters through the natural gas inlet skid-mounted equipment interface 1 The skid-mounted device in the cluster well site, the natural gas inlet skid-mounted equipment interface 1 can be connected to the gas from 1 to 9 gas production trees at the same time; the cluster gas wells are respectively connected to the switch well control valve 2, emergency The shut-off valve 3, the two-phase flowmeter 4, and the single-well shut-off valve 5 are connected in series with the natural gas manifold 10 to form a natural gas pip...

Embodiment 2

[0018] On the basis of Embodiment 1, the on-off regulating valve 2 is a 24V DC electric regulating valve, which has remote switch and valve opening monitoring and control functions. Make adjustments to finally realize the function of remote intelligent switch well. There are two situations for remote well shut-in. One is that when the pressure is abnormal, the gas source is automatically shut off by switching the regulating valve (high pressure) and the emergency shut-off valve (medium pressure). First close the switch regulating valve, and then close the emergency shut-off valve to ensure that the operating pressure of the surface gathering and transportation pipeline system does not exceed the pipeline design pressure, and improve the safety production factor of the gas well. Remote well opening, that is, considering the process of throttling and pressure reduction of high-pressure gas wells and the impact of high-speed gas flow, first open the emergency shut-off valve, adju...

Abstract

The invention provides a movable skid-mounted cluster type well field integrated device. Cluster type gas wells are sequentially connected with switch well adjusting valves, emergency block valves, two-phase flow meters and single-well shut-off valves in series through pipelines via skid-mounted device interfaces respectively and then are connected with a natural gas manifold to form a natural gas pipeline. The natural gas pipeline collects natural gas pipelines of the cluster type gas wells and divides the natural gas pipelines into two ways, one way is sequentially connected with a differential pressure airtight power generation device and a downstream interface in series through a pipeline, and the other way is sequentially connected with a flow control valve, a main turn-off valve and the downstream interface in series through a pipeline. According to the movable skid-mounted cluster type well field integrated device, the gas wells can be remotely switched on and off, power generation can be conducted through the pressure of natural gas, and simple two-phase metering is achieved. The movable skid-mounted cluster type well field integrated device has the advantages of being easy to install, short in construction period and convenient to maintain and can improve the fast building and managing efficiency of a well field.

Description

technical field [0001] The invention relates to a skid-mounted natural gas gathering and transportation device integrated with remote switch well, simple two-phase metering, self-power supply system, and overvoltage and undervoltage protection for cluster well sites, specifically a movable Skid-mounted cluster well site integrated device. Background technique [0002] As the number of gas wells in the Sulige gas field increases year by year, but "increasing production without increasing personnel", it is necessary to continuously improve the rapid production construction and "intelligent" management level of the well site. At present, the on-site construction of the Sulige gas field well site construction project is limited by the climate and equipment, the construction period is long, the organization and coordination are difficult, and the area is large; during the daily production and operation of the gas well, the remote opening operation needs to be operated at the well...
