Xiangyang[9] studied the experimental law of rock imbibition under different conditions through laboratory experiments such as volumetric method and weighing method, and realized that the imbibition of reservoir matrix has a certain effect on reservoir production, which belongs to the early theoretical stage of fracturing oil displacement technology in China.	cache/ajst-9877.pdf	txt/ajst-9877.txt
