针对海上凝析气藏存在井数少、合采井多、稳产难度大、亟待寻找新的储量等问题，以东海X气田为例，进行了地质气藏一体化研究。采用地震地质、动静一体研究方法，依托建模数模技术，开展A储层精细刻画，落实储层平面和纵向空间分布特征，有效解决地质认识和生产动态间的矛盾，定量表征各储层动用情况和剩余气潜力，并得到新钻井的验证。该研究可以较好解决海上少井、复杂地质条件下的剩余气定量表征难题，对同类气藏的挖潜具有借鉴意义。

In view of the problems of offshore condensate gas reservoirs, such as fewer wells, more combined production wells, difficulty in stabilizing production, and urgent need to find new reserves, taking X gas field in East China Sea as an example, the integration research of geology and gas engineering was carried out. The fine characterization of reservoir A was carried out by using the method of seismic geology, dynamic and static integration, and relying on the modeling digital model technology. The horizontal and vertical spatial distribution characteristics of reservoir were implemented, which effectively solved the contradiction between geological cognition and production dynamics, quantitatively characterized the production situation and residual gas potential of each reservoir, and verified by new drilling.This study can better solve the quantitative characterization problem of remaining gas under complex geological conditions with few wells on the sea, and has reference significance for tapping the potential of similar gas reservoirs.
