Abstract

The embodiments of the invention provide a prediction method, device and equipment for dynamic reserves of an oil well and a storage medium. The method comprises the steps that a water replacement rate corresponding to oil well data in a prediction time period is determined according to historical oil well data; based on a first function relationship and the water replacement rate corresponding tothe oil well data in the prediction time period, a second cumulative mixed oil yield produced by the oil well after water injection in the prediction time period is determined; and the dynamic reserves of the oil well in the prediction time period is determined according to the second cumulative mixed oil production. According to the method, the problems that in the prior art, prediction analysisof the oil well dynamic reserves cannot be accurately and effectively carried out in real time, and meanwhile time and resources are wasted can be solved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of oil production engineering, and in particular to a method, device, equipment and storage medium for predicting oil well dynamic reserves. Background technique [0002] With the gradual acceleration of the development of carbonate oil wells, a large amount of remaining oil is buried at the bottom of the well due to the rapid advancement of bottom water. We must find effective technical means to excavate these remaining oil and improve the recovery rate. In the dynamic analysis of reservoirs and the exploration of remaining oil potential, the estimation of dynamic reserves of oil wells is the focus of research, it is a crucial issue in the middle and later stages of oilfield development, it is an important prerequisite for the formulation and adjustment of oilfield development plans, and it is directly related to the economic benefits of oilfields . [0003] At present, the pred...
