Development and current situation of production increasing technology by liquefied petroleum gas
Liquefied petroleum gas(LPG)stimulation technology can effectively increase the drainage area of oil and gas,improve flowback performance,and get a lower reservoir damage also water resource consumption.However,it has yet to be rolled out globally due to many factors such as equipment,safety,cost and crude oil price.This paper will provide a brief review of its technical principles,and focus on its development history,trend and application cases.
