Research and Application of Technology of Mobile Electric Ignition Technology for Fire Flood in Vertical Hole

Abstract:

In-Situ combustion is an important transformation mode for heavy oil development, and the key to its success is ignition in the reservoir, On the basis of investigation and research into some related techniques both at home and abroad, this paper presents the development of mobile electric igniter, technical string, down-hole monitoring system, putting-in and putting-out device; the integral outside diameter of the igniter is φ25.4mm; this paper forms the technique of mobile electric ignition for fire flood in vertical hole and introduces the technical principle. The field test results show that the maximum outlet air temperature of the igniter is 527°C when the steam injection rate is 6500Nm³/d; And that realizes high temperature igniting of mobile electric igniter for the first time. This technique will effectively reduce the operation cost of fire flood, and provides technical reserve for separate zone ignition in thick mass oil pool of Liaohe Oilfield.
