Abstract

The invention provides a three-dimensional flow unit model establishment method, device and equipment, and the method comprises the steps: obtaining the logging information of a target well; dividinga target horizon into a plurality of layers according to the logging information, and obtaining layered data; calculating a flow band index of each layer in the plurality of layers according to the porosity data and the permeability data of each layer in the plurality of layers; establishing a three-dimensional construction model; establishing a three-dimensional sedimentary facies model based onthe three-dimensional construction model; And based on the three-dimensional sedimentary facies model, performing phase control attribute modeling by taking the flow band index of each layer in the plurality of layers as an attribute, and establishing a three-dimensional flow unit model. In the embodiment of the invention, phase control modeling is carried out by taking the flow zone index as an attribute, so that the distribution condition of flow units in each layer can be directly embodied in the three-dimensional flow unit model, thereby more effectively carrying out injection-production well group selection and well pattern well distance adjustment, and further effectively improving the oil field production efficiency and yield.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploitation, in particular to a method, device and equipment for establishing a three-dimensional flow unit model. Background technique [0002] Geological modeling mainly adopts phase-controlled modeling, which provides a reservoir framework for physical parameter modeling, and with the deepening of oil and gas exploration and development, reservoir research turns to the establishment of a three-dimensional reservoir geological model. , the establishment of a three-dimensional facies control model plays an important role in oil and gas exploration and development. A flow unit is a rock mass with similar geological and physical characteristics that has certain continuity in the vertical and lateral directions and affects the flow of reservoir fluid. By dividing the flow units of the reservoir, a 3D facies-controlled model that can accurately reflect the heterogeneity of the reservoir and con...
