<p>Recollection of crude oil is carried out efficiently by a simple device using a winze which is left unattended as an exhausted oil field or an existing winze the volume of production of which is deteriorated. The oil field regeneration method for recollecting crude oil by utilizing an existing winze, characterized by comprising a step for hanging a flame jet burner down into a winze by means of a pair of suspension ropes and one pushing material, a step for forming a lateral hole by firing the flame jet burner after it has reached a target depth and then propelling the flame jet burner while changing the direction circumferential sideways by adjusting the suspension rope and the pushing material while jetting a high-temperature, high-speed flame jet, and a step for forming a layer of crude oil when crude oil, separated from the sand and bedrock by the heat produced when the lateral hole is formed by the high-temperature, high-speed flame jet to be made high in fluidity, flows into the lateral hole.</p> |
