3.4.1. Mining Measures for Different Gas Reservoirs

There are different types of offshore gas reservoirs, and we should take appropriate measures for production according to the characteristics of different types of gas reservoirs.
1. Mining measures for an anhydrous gas reservoir
    Anhydrous gas reservoirs are also called gas reservoirs without edge/bottom water. We do not have to worry about flooding and water channeling in this case, so production measures with anappropriate large differential pressure can be used. The advantages are that we can:
a. Increase the pressure difference between the large seam holes and a slight gap, so that the gas in the small gap can be easily discharged, thereby ...
