Abstract

Abstract: The gas pools exploited in Shengli oilfield mainly belong to lithologic traps controlled by fractures and lithology, with closed and size-restricted water. Their performances in process of development are characterized by low water production and low water/gas ratio. This paper presents the dynamic evaluation method for calculation of water energy, based on the performances and material balance theory. The case study indicates that the calculated result by this method is reliable and practicable.

Key words: gas pool, closed reservoir, edge water, bottom water, evaluation
