对已有的各种驱动方式的砂岩油藏水平井稳态产能公式进行了分析,利用裂缝性地层的列宾逊函数对这些公式进行了修正,使之可用于裂缝性油藏。所给修正公式不仅考虑了裂缝性地层的岩石变形压实作用,还考虑了液体流动的惯性阻力。现场应用表明,这些公式不仅易于实际应用,而且预测结果比较准确。
The steady-state productivity formulas of horizontal wells in various driving sandstone reservoirs have been analyzed, and these formulas have been modified by using the Jacobian function of the fractured strata so that they can be used in fractured reservoirs. The correction formula given not only considers the deformation and compaction of rock in fractured formation, but also considers the inertial resistance of liquid flow. The field application shows that these formulas are not only easy to apply, but also have more accurate prediction results.
