In this paper, the authors have developed a new device and method for measuring the efficiency of spontaneous imbibition and displacement in a low permeability reservoir. The innovative design of the new experimental device effectively combines the traditional volumetric method and the weighing method. The improved reliability of experimental results is provided by the mutual verification of data of the two conventional techniques. The performance and effectiveness of the new method and the device have been verified by experimental tests on a low-permeability core. The results can be useful for understanding the self-priming oil displacement efficiency in a low permeability reservoir.
