With the development time extension, the development effect worse gradually of Chaoyanggou oilfield, There is some low permeability thin oil that traditional production techniques can not realized in Fuyu and Yang da cheng zi layer of Chaoyanggou oilfield. The crude oil viscosity is high; the relationship between viscosity and temperature is sensitive. The viscosity has big fluctuating along with the temperature change. According to the development experience of inspissated pool and the research results of numerical simulation by STARS, thermal recovery technique is an efficient method used to improve the development effectiveness of low permeable and high viscosity blocks.
