Abstract

The invention discloses a special skid-mounted multi-well automatic well selection metering device for coalbed methane, which belongs to the field of surface engineering of coalbed methane gas fields. The automatic well selection metering device at least includes: a multi-well selection metering system, a fuel gas metering system, an intelligent control cabinet, a base and related circuits, and related pipelines; the multi-well selection metering system and the fuel gas metering system Through the total output pipeline of the relevant pipelines, it is integrated with the intelligent control cabinet on the base in a skid-mounted manner, placed near the wellhead block of the coalbed methane field, and connected to multiple single well gas pipelines and external transmission Production manifolds are used for coalbed methane gathering and transportation. Through the combination of automatic well selection system, automatic metering system and automatic monitoring system, the low-cost development and long-term unattended operation of the coalbed methane gathering and transportation metering system can be realized, and labor costs can be reduced. The automatic control of well selection is simple and reliable, which is convenient for overall migration, reduces the workload of on-site construction, occupies a small area, and shortens the construction period.

Description

technical field [0001] The invention relates to the field of coalbed methane field surface engineering, in particular to a skid-mounted multi-well automatic well selection metering device for coalbed methane. Background technique [0002] Coalbed methane is also called "gas", its main component is methane, its calorific value is 2-5 times that of common coal, and its calorific value is equivalent to that of natural gas. It is a good clean energy for industry, chemical industry, power generation and residential life. [0003] The skid-mounted type refers to an integration method in which functional components are integrated on an integral base, which can be installed and moved as a whole. It can be easily moved and placed in place by using a crowbar. [0004] The surface construction of coalbed methane gas field is based on the different geological well patterns, and according to the needs, different well-type metering stations are set up to carry out multiple functions such...
