海上凝析气藏储量计算及评价

Calculation and Evaluation of Reserves of Offshore Condensate Gas Reservoirs

近年来,随着勘探开发的深入,我国发现了许多边底水凝析气藏,因该类凝析气藏具有较高的开发价值,越来越受到人们的高度重视,精确的储量评价对区块的开发尤为重要。针对海上A区块边底水凝析气藏的特定条件,选择容积法计算凝析气藏地质储量,用经验公式法确定其可采储量,最终对储量进行评价,对该区块的认识及开发具有很重要的意义。

In recent years, with the deepening of exploration and development, many gas condensate reservoirs with edge and bottom water has been found in China. Because the condensate gas reservoirs have high development value, they receive more and more attention. The accurate evaluation of reserves is very important to block development. In this paper, based on specific conditions of gas condensate reservoir with edge and bottom water in an offshore block, geological reserve of the condensate gas reservoir was calculated by volumetric method, and the recoverable reserve was determined by the empirical formula method.Finally, the reserve was evaluated.
