Associated gas recovery and treatment device and method

Abstract

The invention belongs to the technical field of associated gas recovery and treatment, and relates to an associated gas recovery and treatment device and method. A main structure of the device comprises a gas collection pipeline, a gas tank, a gas pretreatment vehicle, a pretreatment tank truck, a waste liquid tank truck, a gas booster pump truck, a natural gas hydration absorption vehicle, a water tank truck, a hydrate granulation vehicle, a hydrate storage tank truck and a central control vehicle, the technological process of the method comprises six steps of collection, pretreatment, pressurization, hydration, granulation and collection, and on the basis of the advantages of safe storage and transportation and mild conditions of hydrate in natural gas storage and transportation, oil well associated gas is recovered and treated; and the device is simple in structure and convenient to disassemble and assemble, a large amount of pipeline laying work can be avoided through a movable framework, the construction cost is saved, the defects that the pipeline is low in utilization rate and even abandoned are overcome, the oil well associated gas can be conveniently and rapidly convertedinto hydrate type energy to be stored and transported, and the realization of energy conservation, emission reduction and environmental protection is facilitated.

Description

Technical field: [0001] The invention belongs to the technical field of associated gas recovery and treatment, and in particular relates to an associated gas recovery and treatment device and method, which can conveniently and quickly convert oil well associated gas into energy in the form of hydrates for storage and transportation. Background technique: [0002] The rapid development of society means that more energy is needed to provide the driving force for development. Economic development is often accompanied by serious pollution, which is contrary to the development concept of environmental protection. In order to balance economic development and environmental protection at the same time, it is necessary to seek more high-quality and clean energy. Due to its full combustion and environmental friendliness, the proportion of natural gas in the energy consumption structure is increasing year by year. However, with the development of the national economy, energy consumpti...

Problems solved by technology

However, because oil wells are often located in remote areas, and the associated gas production of a single oil well is not enough to meet the economic requirements of pipeline gathering and transportation, many oil wells choose to directly ignite associated gas for emptying, which not only causes a waste of energy resources, also produces large amounts of greenhouse gases
