Abstract

The invention discloses an oil layer ignition method, device, storage medium and processor. Wherein, the method includes: obtaining the oil layer parameters of the oil layer to be ignited, wherein the oil layer parameters at least include: the oil saturation of the oil layer, the ignition heat required for the stable combustion of the oil layer to be ignited, the fuel deposition ratio corresponding to the ignition heat, and the The first corresponding relationship between the oil saturation of the oil layer and the fuel deposition ratio; obtain the second corresponding relationship between the fuel deposition ratio and the heating rate of the oil layer; according to the first corresponding relationship and the second corresponding relationship, determine the The third correspondence between the oil saturation of the oil layer and the temperature rise rate of the oil layer; according to the third correspondence, the temperature rise rate of the oil layer corresponding to the oil saturation of the oil layer is determined as the ignition temperature rise rate. The invention solves the technical problem that the ignition of the oil layer with low oil saturation is not easy to be successfully ignited in the technology of burning the oil layer.

Description

technical field [0001] The invention relates to the field of oil recovery in heavy oil fields, in particular to an oil layer ignition method, device, storage medium and processor. Background technique [0002] In recent years, the combustion oil layer technology has gradually shifted from laboratory research to field tests and industrial applications. Among them, the vertical well fire flooding technology can be applied to heavy oil mature areas that have reached a high degree of recovery in the late stage of steam injection development. [0003] Table 1 shows the economic limit air-oil ratio and the lower limit of the average remaining oil saturation under different oil prices. The demonstration shows that when the oil price changes from 30 US dollars / barrel to 100 US dollars / barrel, the lower limit of the average remaining oil saturation of the area well pattern is 61.6%-26.9%; the lower limit of the average remaining oil saturation of the linear well pattern is 75.3%-25.5...
