Abstract

The invention discloses a discrete optimization method for water flooding oil field development planning. The method comprises the following steps that S10, the oil production amount and the workloadof water flooding oil field development are discretized; S20, a water flooding oilfield development yield prediction model is established; S30, a water flooding oil field development planning objective function is determined; S40, a water flooding oil field development planning constraint condition model is established; and S50, the objective function is solved by using MATLAB software according to the function established in the four steps. The invention provides a discrete optimization method for a water flooding oil field development plan, which is used for the water flooding oil field development plan, provides an optimal development mode for the water flooding oil field development, provides a basis for an oil field development plan manager to select a development plan scheme, avoidsthe waste of development resources, and saves the development cost. Therefore, a new discrete optimization method for the development planning of the water flooding oil field is formed, and objectivity, accuracy and practicability are achieved.

Description

technical field [0001] The invention relates to the technical field of oil and gas field development, in particular to a discrete optimization method for water flooding oil field development planning. Background technique [0002] Oil is an important conventional resource, and the development of water drive oilfield is a complex system. The development of water drive oilfield involves multiple development blocks, old wells in old areas, new wells in old areas and new wells in new areas. The ultimate goal of water drive oilfield development is to achieve the maximum overall benefit and total net present value of the water drive oilfield. Factors affecting the benefits of waterflood development oilfields include depreciation of fixed assets, operating costs of stock, management costs per unit of oil, sales costs, operating costs of natural oil, investment that should be borne by new well production, measure costs for production allocation of measures, unit Some of these facto...
