Embodiment Construction

[0044] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but 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 shall fall within the protection scope of the present invention.

[0045] A single sand body is a relatively independent oil storage unit of a reservoir. Because of the different structures, thicknesses and types of sedimentary microfacies among different single sand bodies, the oil storage volume, oil storage location and production difficulty in different single sand bodies are different. In ...

Abstract

The invention discloses a reservoir production method and device. The method includes the steps of selecting a plurality of exploitable single sand bodies from a to-be-produced reservoir, dividing deposition ages of all the exploitable single sand bodies to obtain first division results, dividing the exploitable single sand bodies into a plurality of geological data bodies belonging to the same formation period and located in the same river channel according to the first division results to obtain second division results, deploying producing wells in the middle of the to-be-produced reservoir according to the second division results, thereby producing later-period residual oil of the reservoir and achieving the aims of improving the reservoir reserve employing degree and improving the block recovery efficiency.

Description

technical field [0001] The invention relates to the field of oil exploration, in particular to an oil reservoir exploitation method and a device thereof. Background technique [0002] The sandstone reservoirs of channel subfacies and subaqueous distributary channel microfacies are extremely important types of oil reservoirs, and the oil reserves of this type of reservoirs have accounted for about half of the produced reserves of currently developed oilfields. With the deepening of exploration work in such reservoir oilfields, many oilfields have entered the stage of ultra-high water-cut production, the distribution of remaining oil in the reservoir has become extremely complicated, and the difficulty of oil recovery has become more and more difficult. [0003] For how to effectively increase the oil recovery of such reservoirs, no effective solution has been proposed so far. Contents of the invention [0004] In view of the above problems, the object of the present invent...
