Pressurization Time of Individual Well in Daniudi He3 Gas Reservoir

Daniudi He3 gas reservoir is a closed gas reservoir, which belongs to a low pressure and low permeability reservoirs. In this reservoir, the gas production rate of individual well is low and the reservoir pressure drops rapidly. That leads to increasing difficulty in stable. Aiming to the current problems in development, it makes decline analysis of wellhead pressure of constant production, and forecasts the stable production years. The result shows that stable production years are different, but most of them can achieve 5 years. The time of the stable production years is called pressurization time of individual well. For the well that the stable yields can not achieve 5 years, it shall use the method of increasing liners pressure to get a stable production and enhance gas recovery.
