TL;DR: In this paper, the authors proposed a utility model for spontaneous imbibition of a rock core device, which includes: the shell, its inside has the chamber that holds that is used for holding rock core and imbibitions liquid, oil quantity measurement spare, it is connected in the shell top to with hold chamber intercommunication, peel off the piece, be the annular and fix and holding the intracavity, peel out an inboard accommodation space that supplies to place the rock core that forms, ejection spare, portability ground and shell sealing connection.

TL;DR: In this article, a method and a device for determining a water-flood sweep efficiency of multi-layer reservoirs is presented, which comprises the steps of acquiring physical property parameters of each reservoir stratum in a work area, acquiring a waterflood front saturation of each stratum according to the physical property parameter of each basin stratum, determining a separate injection quantity of each binar stratum; determining water-front motion speed, breakthrough time, and sweep efficiency.

TL;DR: The utility model provided an imbibition experimental apparatus of simulation hollow billet power and buoyancy as discussed by the authors, which includes an at least one imbibion liquid bottle for holding liquid, glass board device including two vertical placing and the glass board that links together of make-up, pore system that was used for holding crude oil between two glass boards, and at least catheter.

TL;DR: In this article, a method, device and system for determining the water-flood response state of an oil well is described, which comprises steps of: acquiring the production data of the oil well and calculating an water-FLOW response characteristic index based on production data.
