冷 X 区块经过2006年注水开发阶段后已大面积开发,含油总面积3.5 km2、地质储量3.19×106 t。冷 X 油藏物性差,平均渗透率在15×10-3μm2,属于典型的深层低渗透油藏,该区块注水开发效果差,开展注空气驱研究具有非常重要的意义。针对冷 X 块注气井组的地质特征,利用多组分模型软件,完成了三维地质模型的建立,生产历史拟合和动态预测等。该油藏通过注空气开采,能大幅度地提高该区块的原油采收率。

Leng X block,the development stage by inject water,has a large area of development after 2006.Area of oil has together 3.5 km2 ,geological reserves have 3.1 9 × 10 6 tons.The physical properties of reservoir are poor and the average permeability is 1 5×10 -3μm2 ,it is a typical of low permeability reservoir.The reservoir have difficulty in water injection,poor well conditions and low production.“Gas injection”is the most efficient recovery method of low permeability reservoir .In accordance with the geological features of Leng X block,by using multi-component model of software,three-dimensional geological model was established,production history was matched and performance was predicted .The oil recovery of reservoir can be improved by gas injection.
