The Method for Determination of Abandonment Pressure in Water-Bearing Gas Pool

Abstract

Abstract: The abandonment pressure of water-bearing gas pool is the key parameter to ascertain the recovery factor, directly influencing the recovery size. This paper takes account of the change of parameters that have big impact on water-bearing gas well productivity equation and derives a binomial coefficient equation for it under different damage degrees and harm radius at any moment. Under a definite collar production working, such an abandonment pressure can be ascertained using minimum liquid-carrying velocity at minimal bottomhole flowing pressure as constraint condition.

Key words: gas pool, binomial, coefficient, abandonment pressure
