The steam drive area of the Qingshuihe Formation in the Hong003 well area belongs to a super heavy oil to ultra heavy oil reservoir. Since 2008, the development method of first soaking and then steam drive has been adopted, and has been gradually put into development, forming 53 steam drive well groups. By the end of 2021, the cumulative production of crude oil is 95.6% × 104 t, recovery rate 35.5% (throughput 28.0% + steam drive 7.5%), cumulative oil vapor ratio 0.182, comprehensive water content 85.6% (steam drive comprehensive water content 91.7%), and the reservoir has entered a high water content development stage. At present, the contradiction of steam channeling is prominent, the utilization rate of steam heat is decreasing, and the development effect of steam drive is gradually deteriorating. In order to further improve the recovery factor in the middle and later stages of steam drive, the “injection production linkage plugging and drainage combination” enhanced recovery scheme is formulated to plug the steam channeling channels of Injection well and medium and high temperature steam channeling production wells, and then implement viscosity reduction assisted steam drive to improve the low temperature fluidity of crude oil, taking Well Cluster 9 in the steam drive pilot test area of Well Hong003 as the target, based on the research on the characteristics of steam channeling and the distribution of remaining oil, and based on the results of laboratory theoretical research and numerical simulation research, And on-site tests were conducted. The test results show that after the measures taken by the pilot 9 well group, the daily liquid production is relatively stable, and the daily oil production has increased to a maximum of about 30 t, with an average daily oil increase of 10–20 t, and the effect is significant. The strategy of “injection production linkage blockage and drainage combination” can effectively solve the contradiction of hot water channeling in strong heterogeneous reservoirs in the Hong003 well area, and meet the needs of improving quality and efficiency development.
