Skid-mounted multi-well automatic well-selection metering device special for coal bed gas

Abstract

The invention discloses a skid-mounted multi-well automatic well-selection metering device special for coal bed gas, and belongs to the field of coal bed gas field ground engineering. The automatic well-selection metering device at least comprises a multi-well well-selection metering system, a fuel gas metering system, an intelligent control cabinet, a base, a relevant circuit and a relevant pipeline, wherein the multi-well well-selection metering system and the fuel gas metering system are communicated through a main output pipeline of the relevant pipeline, are integrated with the intelligent control cabinet on the base in a skid-mounting way, are arranged close to the well hole area of a coal bed gas field, and are connected with a single-well incoming gas pipeline and an output production manifold to gather and transport coal bed gas. Through the combination of the automatic well-selection system, the automatic metering system and the automatic monitoring system, low-cost development and long-period unattended operation of a coal bed gas gathering and transportation metering system are realized, and the labor cost is lowered. Well selection automation is easy and reliable to control, convenience is brought to overall migration, the field construction workload is reduced, the floor area is small, and the construction period is short.

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...
