摘　　要：针对裂缝性稠油油藏蒸汽驱过程中波及段和未波及段流体性质差别,在稠油油藏双孔两区基础上提出裂缝性稠油油藏复合三区试井模型,求出Laplace空间解,利用数值反演得出试井样板曲线,对该曲线做了敏感性分析。该研究为裂缝性稠油油藏的研究提供了依据。Aiming at the fluid property difference between the steam sweeping and up-swept regions during steam driving in heavy oil fissured reservoirs,this paper proposes a new well test model which consists of three regions.This new model is based on steam simulation of double porosity media in heavy oil reservoir.A solution in Laplace space under the condition of infinite formation is obtained,and the method of numerical inversion is used to obtain the corresponding type curves for which a sensibility analysis has been conducted.This paper provides a reliable basis for fissured heavy oil recovery.
