The invention discloses an injection-production inter-well three-dimensional wave and
volume determination method considering interlayer longitudinal seepage. The method comprises the following steps: S1, acquiring basic
data information; s2, determining the quasi-tracer concentration and the three-dimensional swept volume of the water
injection well considering interlayer longitudinal seepage, including: 1) determining the three-dimensional swept range of the water
injection well; (2) based on the three-dimensional wave and range of the water
injection well, the grid simulated tracer agent concentration in the three-dimensional wave and range considering interlayer longitudinal seepage is determined; 3) determining the three-dimensional swept volume of the water injection well based on the three-dimensional swept range of the water injection well; s3, the simulated tracer agent concentration and the three-dimensional oil
drainage volume of the oil producing well considering interlayer longitudinal seepage are determined; and S4, setting a simulated tracer concentration threshold value, and determining the three-dimensional wave and volume between the injection and production wells considering the interlayer longitudinal seepage. According to the method, rapid calculation of the quasi-tracer concentration is achieved, and then rapid and quantitative evaluation of the three-dimensional swept volume of the water injection well, the three-dimensional oil
drainage volume of the
oil production well and the three-dimensional swept volume between the injection well and the production well is achieved.
