Research Progress of Working Fluids for natural Gas Exploitation
Unconventional natural gas is difficult to be exploited due to problems such as more prone to wellbore collapse and damage to oil and gas layers.Liquid,as the blood of the oil and gas exploitation industry,can solve the problem of difficult exploitation of unconventional natural gas to a certain extent.This paper reviews the research progress of working fluids for natural gas exploitation and specifically proposes future research directions.The conclusion is that the continuous development of low-toxicity,multi-functional and intelligent working fluids is crucial for promoting the green and low-carbon development of the natural gas industry.
