Shale cluster well gas collection platform technological process and method

Abstract

The invention relates to a cluster well gas collection platform technological process and method. The cluster well gas collection platform technological process and method meet the standard design requirement and specifically comprise the processes of wellhead throttling, sand removing and filtering, heating throttling, gas-liquid separation and alternate metering, pipe cleaning and ball serving,pre-pressurization and the like, namely, devices such as a cyclone desander, a filtering desander, an electric throttling valve, a water jacket heating furnace, a gas-liquid two-phase horizontal separator, a conical orifice plate flowmeter, a mass flowmeter, a pipe cleaner and ball serving barrel and a reciprocating piston compressor are included, skid-mounted integration and splicing mounting areadopted, carrying and dismounting are easy, and the cyclone desander and a production separator are structurally optimized. The technological processes and devices adopted in different production periods are different, in the liquid discharging production period, the two-stage sand removing, two-stage throttling and separation process with the large processing capacity is adopted, in the high-yield period and the stable-yield period, skid-mounted equipment with the surplus load can be dismounted and then carried to other newly-built platforms to be used, the platform construction and equipment mounting period is short, and the investment cost is low.

Description

technical field [0001] The invention belongs to the production technical field of a cluster well gas gathering platform for shale gas exploitation, and in particular relates to a process flow and method for testing and processing a cluster well gas gathering platform. Background technique [0002] Shale gas refers to an unconventional natural gas resource that is mainly accumulated in organic-rich dark mud shale and its interlayers, mainly in the form of adsorption or free. As a clean and efficient energy source, shale gas can be used for industrial fuel, chemical power generation and civil use, etc. It can fully alleviate the shortage of oil and gas resources at the present stage, increase the proportion of natural gas in the energy structure, solve the problem of energy shortage, and ensure my country's energy security , promote the development of green energy, and improve the ecological environment. According to relevant data, the geological resources of shale gas in my c...
