Sedimentary microfacies determination method and device, electronic equipment and storage medium

Abstract

The invention relates to a sedimentary microfacies determination method and a device, electronic equipment and a storage medium, and relates to the technical field of oil and gas field development reservoirs, and the sedimentary microfacies determination method comprises the following steps: obtaining a planar grid distribution diagram of a research area; determining a to-be-updated sedimentary microfacies type of each grid in the planar grid distribution diagram according to the planar grid distribution diagram; determining a plurality of contact relationships of adjacent grids according to the sedimentary microfacies type of each grid; and updating the to-be-updated sedimentary microfacies type according to the plurality of contact relationships, and determining the updated sedimentary microfacies type of each grid. According to the embodiment of the invention, the problem of inaccurate sedimentary microfacies at present can be solved. The requirements of high efficiency, accuracy and quickness of reservoir fine description cannot be met; the method conforms to the drawing characteristics of the contact relation of the sedimentary microfacies, and the sedimentary microfacies canbe accurately determined.

Description

technical field

[0001] The disclosure relates to the technical field of oil and gas field development reservoirs, in particular to a method and device for determining sedimentary microfacies, electronic equipment and storage media. Background technique

[0002] After more than 50 years of development, Daqing Changyuan Oilfield has entered a period of ultra-high water cut, and the remaining oil is highly scattered. The production status is still poor, the remaining oil is relatively rich, and there is great potential for fine development and adjustment. In order to improve the development effect of thin and poor oil layers, accelerate the research on enhanced oil recovery technology of thin and poor oil layers, and explore new ways to improve the development effect of thin and poor oil layers, it is imminent to finely describe the dense well pattern of thin and poor oil layers.
