摘要

Horizontal well is an effective technique for developing the shallow layer and super heavy oil reservoir, and the development technology policy plays a vital role in the success or failure of the horizontal well deployment and development. According to the shallow buried depth, thin thickness, strong heterogeneity, high oil viscosity, large differences in viscosity of N_(7+8) block reservoir, according to the distribution characteristics of different viscosity, the N_(7+8) block is divided into 4 different regions of the different viscosity, the horizontal well steam development rules in the different viscosity region were researched by using numerical simulation method, the sensitivity of geological parameters, development design parameters and steam injection parameters influence the steam soak effect of horizontal well were analyzed and optimized, technical limits of key factors and reasonable design parameters, steam injection parameters were determined, which provide the decision basis for enhancing oil recovery, further infilling horizontal well and effectively transforming the development mode.
