The invention relates to an oil well layered yield splitting method based on dynamic and static coupling, which can solve the technical problems of poor adaptability and large calculated amount of thetraditional splitting method. The method comprises the following steps: S100, determining a static splitting coefficient; resetting single well perforation data according to a layering result, and generating a static splitting coefficient according to a single well logging interpretation result and the perforation thickness; S200, determining a single well profile splitting coefficient; generating a profile splitting coefficient after the liquid production profile data is reset layer by layer; and S300, determining a dynamic splitting coefficient according to the static splitting coefficientand the profile splitting coefficient. The oil well layered yield splitting method based on dynamic and static coupling has the following beneficial effects that (1) coupling splitting of a single well production and suction profile is achieved, the method is reasonable and effective, and the precision requirement of residual oil research can be met; (2) the method is simple, easy to operate andhigh in generalization performance; and (3), compared with a numerical simulation research method, the working time can be effectively saved, and the working efficiency is greatly improved.
