Abstract

The invention disclose a shale gas high-pressure discharge and mining integrated skid-mounted device as well as a discharge and mining technology and a mounting method thereof, and belongs to shale gas discharge and mining devices. The shale gas high-pressure discharge and mining integrated skid-mounted device comprises a sand removing skid, a heating furnace skid and a separate metering skid, wherein a gas-liquid separator is arranged in the separate metering skid, and flow meters are respectively arranged on a liquid outlet pipeline and a gas outlet pipeline of the gas-liquid separator; an air inlet of the sand removing skid is an air source air inlet, an air outlet of the sand removing skid is respectively communicated to an air inlet pipeline of the heating furnace skid and an air inlet pipeline of the gas-liquid separator, and valves are respectively arranged on the air inlet pipelines of the heating furnace skid and the gas-liquid separator; an air outlet of the heating furnace skid is communicated to the air inlet pipeline of the gas-liquid separator. By adopting the device, the integration of skid-mounting is realized, the device is convenient to move, and the mining efficiency of natural gas is improved.

Description

technical field [0001] The invention relates to a shale gas extraction device, in particular to a skid-mounted device for high-pressure extraction of shale gas and its extraction process and installation method. Background technique [0002] As a very important unconventional natural gas resource, shale gas is different from conventional gas fields. It has the characteristics of high pressure and high output in the early stage of exploitation, and low output and rapid decline in pressure in the later stage. It cannot follow the development ideas of conventional gas fields step by step. How to find out the law of gas-liquid changes in shale gas while meeting the production needs, and provide accurate data for the formulation of later production management systems and gas field water treatment, this requires the production of shale gas clusters in normal production. Real-time continuous detection and measurement of natural gas and gas field water. At the same time, in order to...
