Aimed at the problem of spontaneous imbibition physical simulation test using volume method and weighing method，In this paper，a set of device and method for measuring the efficiency of spontaneous imbibition and displacement in low permeability reservoir was developed. Through the innovative design of experimental method and device，the traditional volume method and weighing method were effectively combined to realize the mutual verification of the two data and improve the reliability of the experimental results. A low-permeability core was used to verify the operability of the device and method. The study of self-priming oil displacement efficiency in low permeability reservoir plays a positive role.
