It is the mining characteristics of any single a mining method doesn’t have. In the process of the development of InSitu Combustion technology, the traditional InSitu Combustion technology because its producing method, make recovery limited to rise further. Meanwhile, traditional InSitu Combustion technology production methods of instability to InSitu Combustion well pletion technology research brings about many problems. With vertical wellshorizontal wells and horizontal wellshorizontal wells of horizontal bination gravity discharge of auxiliary principle of new technology proposed overe traditional InSitu Combustion technology has many problems, further improve the recovery. Because of this new technology can be stable production, the InSitu Combustion well pletion 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, bined with the modern InSitu Combustion technology development trend, obtain corresponding pletion needs, again according to the needs of the well pletion technology is analyzed and the optimization study, so as to find the most suitable well pletion technology to improve the fire flooding development efficiency. For the implementation of the InSitu Combustion technology to provide the reference.
