Abstract
Steam assisted gravity drainage (SAGD) has a better effect on heavy oil development than other thermal recovery methods. However, during the SAGD production practice, the problem of uneven temperature distribution of long horizontal well sections has appeared. In response to this problem, the reservoir numerical simulation software CMG is used to simulate different steam injection methods for SAGD horizontal well sections. The results show that the conventional steam injection steam cavity only develops at the heel end, the development length is 1/3 of the length of the horizontal section, and the steam suction profile is uneven. The double-pipe steam injection steam cavity develops at the heel and toe ends, and the steam suction profile is uniform. Improved, multi-point steam injection steam chambers are developed along horizontal wells, and the steam suction profile is the most uniform.
