The Numerical Simulation Study And Test Tracking On Fire Flooding Of Zhong18

The burning oil layer is divided into the direct well fire flooding and the horizontal well fire flooding(CGD).The CGD technology is the combination of gravity drainage and combustion oil layer technology,through vertically injecting steam into the well and light a fire,combustion oil layer,the use of gravity drainage by horizontal wells produced a development method,Mainly used for heavy oil,super heavy oil reservoir.But conventional straight well fire flooding has some limitations.Compared with the direct well fire flooding,the CGD technology has the advantages of high thermal efficiency,the stability of the gravity to the combustion front,and the short distance of the oil heat transfer.However,due to the mechanism of fire flooding and the complexity of strata,it is difficult to accurately judge and understand the combustion state and fire line advancement in the process of fire drive.Therefore,it is difficult to control the dynamic control.According to the geological model and indoor physical simulation experiment,the corresponding numerical model is established by using CMG-STARS module.The numerical simulation is used to simulate the fire Parameters,fire line propulsion form,and the line of fire to promote the stability of the control measures such as analysis,for heavy 18 wells CGD technology research to provide new ideas.
