傾斜層狀油藏水驅(qū)效率預(yù)測模型
[Abstract]:Inclined bedded sandstone reservoirs are characterized by large dip angle, strong longitudinal heterogeneity and large thickness, and accurate prediction of water drive efficiency of layered reservoirs can provide an important basis for rational development of oil fields. The stratiform model studied at present neglects the influence of reservoir inclination and gravity. In view of the large dip angle of stratified reservoir and the influence of gravity factors, the reservoir dip angle, interlayer channeling flow and gravity differential displacement conditions are taken into account at the same time. By introducing pseudo-relative permeability curve and weighted average physical properties according to thickness and combining with water flooding theory, a water drive efficiency model for inclined bedded sandstone reservoirs is established. The calculation results show that the new model is in good agreement with the actual production data, which proves the reliability and applicability of the new model. The sensitivity analysis shows that when the dip angle of the reservoir increases, the gravity makes the water flow along the reservoir with lower permeability, which delays the water breakthrough time of the upper permeability reservoir and increases the displacement efficiency. The smaller mobility ratio and permeability coefficient of variation, the greater the displacement efficiency.
