Description
Technical Field
The invention relates to the technical field of natural gas exploitation, in particular to a protection device for natural gas exploitation.
Background
Natural gas mining also has its own features. First, natural gas, like crude oil, is often a reservoir system, as is bottom water or side water. Along with the exploitation process of natural gas, the elastic energy of the water body drives water to flow into the gas reservoir along the high-permeability zone. In this case, the intrusion of water is not an effective displacement of gas due to the hydrophilic nature of the rock itself and capillary pressure, but rather closes the gas that is not vented from the crevice holes or voids, forming a dead gas zone. The amount of the high-pressure gas trapped in the water invasion zone can be as high as 30-50% of the pore volume of the rock, so that the ultimate recovery rate of the gas reservoir is greatly reduced. Secondly, after the gas well produces water, the seepage resistance of gas flowing into the bottom of the well is increased, and the total energy consumption of gas-liquid two-phase flow along the upward pipe of the oil well is obviously increased. With the increasing influence of water invasion, the gas production speed of a gas reservoir is reduced, the self-blowing capacity of a gas well is weakened, the yield of a single well is rapidly decreased, and the production is stopped until the bottom of the well is heavily accumulated with water. The natural gas pipeline refers to a pipeline for conveying natural gas (including associated gas produced by an oil field) from a mining place or a processing plant to a city gas distribution center or an industrial enterprise user, and is also called a gas transmission pipeline. The natural gas pipeline is used for conveying natural gas, and is a way for conveying a large amount of natural gas on land.
