宝浪油田宝北区块低渗透油藏层系优化研究

Optimized Layer Division of Low Permeability Reservoirs in Baobei Block in Baolang Oilfield

针对宝浪油田宝北区块低孔低渗油藏地质特征以及油层层数多、分布井段长、部分零散层动用难度大等问题 ,研究了宝北区有效厚度、油层层数、单井产能及单井控制地质储量等层系划分与组合的技术经济界限 ,并在此基础上进行了宝北区层系划分与组合优化论证 。

In view of the geological features of reservoirs with low porosity and low permeability in Baobei block in Baolang oilfield and production complexities such as the large number of oil layers, long oil layer distribution interval and scattered oil layers, we studied the technical and economical limits of layer series division and combination in Baobei block including effective thickness, number of oil layers, single well productivity and single well controlled geologic reserves. Optimization of layer series division and combination was performed and optimal development layer series were selected.
