Abstract
Due to the oil field has been mined production for a long period of time, strata for direct production of crude oil quantity is less and less, and the remaining oil exploitation is the key to improve recovery factor. Study on the method of inter well remaining oil detection theory and technology has become the hot spot. Residual oil mostly existed between casing, whole space model is established, the two radius of 0.1 m and wall thickness of 0.01 m casing place in medium of the whole space, using the casing’s high conductivity characteristics, through calculation and analysis on steady-state solver, get the current density distribution curve of casing in cross section. Research results show that the analysis of inter well reservoir and cross-hole no reservoir at the time of the current density distribution, as well as the current density values, theory and method for inter well remaining oil research to provide certain theoretical support.
