Novel shale natural gas treatment process

Abstract

The invention discloses a novel shale natural gas treatment process. The novel shale natural gas treatment process includes a sand removal device, a natural gas heating device, a gas-liquid separationdevice, a metering device, a natural gas transmission device, a natural gas emptying ignition device, and connecting pipes and valves between the devices. In the novel shale natural gas treatment process, the sand removal device can remove impurities such as sediment and particulate matter in the natural gas to prevent the sediment in the natural gas from blocking the pipes and the instruments, and reduce washout to the inner wall of the pipes; the natural gas heating device can ensure that the natural gas is at a certain temperature, and can prevent condensation in the moisture in the natural gas to prevent appearance of liquid water in the natural gas after the temperature of the natural gas is reduced; and the metering device can measure the natural gas production and water output of each well. The novel shale natural gas treatment process has good economic benefit and social benefit, and is suitable for popularization and usage.

Description

technical field [0001] The invention relates to a natural gas treatment process, in particular to a shale natural gas treatment process, and belongs to the technical field of energy. Background technique [0002] Shale gas is a kind of unconventional natural gas. Shale gas is natural gas that exists in shale and mudstone formations and their interlayers in the form of adsorption and dissociation. my country is rich in shale gas resources. With the advancement of mining technology, domestic shale gas has developed rapidly. At present, many shale gas fields have been built in China. However, each gas field has its own geographical location and environment. The differences in geological conditions, gas reservoir conditions, and recoverable reserves lead to different shale natural gas treatment processes in each gas field, which has a negative impact on the rapid development of shale natural gas. [0003] At present, the shale gas natural gas treatment process commonly used in v...

my country is rich in shale gas resources. With the advancement of mining technology, domestic shale gas has developed rapidly. At present, many shale gas fields have been built in China. However, each gas field has its own geographical location and environment. Different geological conditions, gas reservoir conditions, and recoverable reserves lead to different shale natural gas treatment processes in each gas field, which has a negative impact on the rapid development of shale natural gas

[0003] At present, the shale gas treatment process commonly used in various shale gas fields in China has the disadvantages of easy condensation during natural gas transportation, easy blockage of pipeline instruments and equipment, and unstable production process.
