The invention provides an adjusting and controlling design method for a water-drive oil reservoir planar flow field. The adjusting and controlling design method comprises the steps that 1, oil-water boundary flow field analyzing is conducted, and distributing of a pressure field and a velocity field of single-phase flow under the conditions that a well network is fixed and the amount of injectionproduction is stable is calculated; 2, an oil-water boundary and a production well near well flow boundary are discretized, and the ideal velocity vector and the actual velocity vector for obtaining the discrete position are calculated; 3, an evaluation coefficient is obtained, and the differences between the ideal velocities of a boundary flow field and a single well flow and the actual velocities are calculated correspondingly; 4, whether the adjusted evaluation coefficient meets the expected value or not is judged, and when the evaluation coefficient meets the expected value, the procedureenters into the step 5; and 5, the optimal well network and injection production adjusting and controlling design scheme is obtained according to the result of the evaluation coefficient. According tothe adjusting and controlling design method for the water-drive oil reservoir planar flow field, whether a current flow field meets needs of distributing of an oil reservoir or single-well oil and water or not can be evaluated quickly and quantificationally, and a basis is provided for formulating a reasonable flow field adjusting and controlling strategy.
