In view of Shallow and Thin-Bedded Heavy Oil Reservoirs, it belongs to the forbidden zone which can not be developed by the internationally recognized. To reduce the cost of well drilling and well completion, Φ139.7 mm casing is adopted in well completion. In the early Pilot test, there were many problems in steam injection with blank tubing, low thermal efficiency of steam injection, casing and cement mantle damaged seriously, and even as worse as well abandonment. To solve the problems, the Insulated and Injection-Production integration tubing string was designed by the Y341-115 insulation packer and other supporting tools, which can solve wellbore heat insulation and reverse circulation well cleanup in production. It carried out the function that multicycle steam injection and production can be integrated in one-trip. The large scale application showed that the effect of heat insulation was remarkable, which reduced the production cost, made the shallow and thin-bedded heavy oil reservoirs develop economically and effectively.
