| 摘 要： | 通过建立流入动态关系体系的合理性边界条件,提出了溶解气驱在井新的流入动态方程,新方程涵盖了Vogel方程和retkovich方程,对溶解气驱油藏具有普遍适用性;流入动态影响因素敏感性分析表明,原油饱和压力是影响流入动态非线性程度的主要因素,同时得到了方程指数与饱和压力的变化关系;通过研究不同污染程度下的产能变化,得到了污染因子对流入动态的校正方程。

| Abstract: | Based on reasonable boundary conditions for inflow performance relationships (IPR), a new IPR equatlon for solution gas drive vertical well is presented. It overlaps Vogel's equation and Fetkovich's equation, and can be used extensively in solution gas drive reservoirs. Influential factors' sensitivity analysis of inflow per formance showed that saturated pressure of crude oil was the major factor to affect IPR curvature, meanwhile, a functional relation between equation exponent and saturation pressure was obtained. Through the study of productivity variatlon under dlfferent damage degrees, a calibration equation for inflow performance influenced by damage factors was obtained. |
