Description

Technical Field

[0001] This utility model relates to the field of oil and gas production and transportation, and in particular to a metering skid for multiple well locations. Background Technology

[0002] In the oil and gas industry, gas well extraction faces the problem of high production and operation costs. The typical process route for gas well surface gathering and transportation is as follows: oil and gas resources are throttled from the wellhead through a cage-type throttle valve, heated by a water jacket heater, separated by a separator, metered by a metering unit, and finally transported to the downstream pipeline network.

[0003] However, in current gathering and transportation processes, metering and separation systems are often set up separately. For situations where there are multiple gas wells in the same area, this means that metering and separation devices need to be installed separately for each gas well. This is especially true for large-scale gas fields, where the integration of metering and separation devices is low. The separate configuration of metering and separation devices will lead to the installation of a large number of gathering and transportation equipment pipelines. The installation of metering and separation devices at gas production sites is cumbersome, greatly increasing the investment costs of equipment and land use, and also bringing many inconveniences in management. Utility Model Content
