Embodiment Construction

[0041] In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0042] At present, most oil reservoirs in my country are in the middle and late stages of development, such as layered sandstone reservoirs. Near the pinch-out position of the sand body in the reservoir (also called pinch-out position between sand bodies), it is difficult to control the development well pattern used for production (that is, the development well pattern is difficult to be effectively controlled), and The injection-production relationship at the pinch-ou...

Abstract

The embodiment of the invention provides a method and device for determining a pinch out position of a sand body and a storage medium, and belongs to the field of oil exploitation. According to the method, the second thickness of the sand body at other positions, except the position where an oil well is located, in the distribution area of the sand body is determined based on the first thickness of the sand body in each oil well; and then the pinch out position of the sand body is further determined based on the first thickness and the second thickness, that is, the sand body thickness is fully considered in the determination method, and therefore the method is higher in precision of the final determined pinch out position.

Description

technical field [0001] The present application relates to the field of oil exploitation, in particular to a method, device and storage medium for determining pinch-out positions of sand bodies. Background technique [0002] The sand body refers to the sand layer with a certain distribution range, and the pinch-out position of the sand body refers to the position where the sand layer disappears. Accurate identification of the pinch-out location of sand bodies is the basis and key to exploiting oil near this location. [0003] In the related art, the pinch-out position of the sand body is directly determined as the position of one-half or two-thirds of the distance between the well with the sand body of the sandstone reservoir and the pinch-out well of the sand body. [0004] However, the accuracy of the pinch-out position of the sand body determined by the position determination method of the related art is low. Contents of the invention [0005] Embodiments of the presen...
