凝析气藏是介于油藏和纯气藏之间的复杂类型的特殊油气藏,具有相态、流态复杂的特点。特别是陆相沉积储层具有储层低孔、低渗、非均质性强、地层易发生反凝析、易液锁等现象,开采难度大。该文以宝浪油田宝中区块凝析气藏的开发方案为实例,采用数值模拟方法并结合气藏工程方法对该区块的井型进行了筛选;同时,对不同开发方式(衰竭、循环注气)进行指标预测,对比出最优的开发方案,并提出开发建议。 Condensate gas reservoirs are complex types of special oil and gas reservoirs between reservoirs and pure gas reservoirs. They have the characteristics of phase state and fluid regime. In particular, continental sedimentary reservoirs have the characteristics of low porosity, low permeability, high heterogeneity, prone to retrograde condensation and easy liquid-lock in the strata, which makes it difficult to mine. This paper takes Baozhong oilfield Baozhong block condensate gas reservoir development program as an example, using numerical simulation method combined with gas reservoir engineering methods to screen the block well pattern; at the same time, different development methods (failure, Cycle gas injection) index prediction, comparison of the best development programs, and put forward the development proposal.
