It is the mining characteristics of any single a mining method doesn’t have. In the process of the development of In-Situ Combustion technology, the traditional In-Situ Combustion technology because its producing method, make recovery limited to rise further. Meanwhile, traditional In-Situ Combustion technology production methods of instability to In-Situ Combustion well completion technology research brings about many problems. With vertical wells-horizontal wells and horizontal wells-horizontal wells of horizontal combination gravity discharge of auxiliary principle of new technology proposed overcome traditional In-Situ Combustion technology has many problems, further improve the recovery. Because of this new technology can be stable production, the In-Situ Combustion well completion technology research brought convenient. This paper focus on the gravity of the principle of discharge of oil reservoir technology, through the research of ignition, temperature, corrosion, and sanding factors, combined with the modern In-Situ
