Research on Influencing Factors of Fracture Propagation in Basement Rock Fractured Reservoir

The paleo-central uplift zone in the northern Songliao Basin is the key area of risk exploration because of the wide realm and bright prospects for the exploration of gas and oil. The reservoir has the characteristics of complex lithology and compact matrix structure which make the poor result of well stimulating using conventional fracturing and low exploration level. We shall, therefor, explore targeted fracturing measures to improve the reservoir connectivity. We analyzed and compared the influence of different geological and engineering parameters in hydraulic fracturing, in order to maximize the effect of fracture reconstruction in basement rock fractured reservoir. In this paper, the large-scale true triacial hydraulic fracturing simulation system is carried out to analysis the influencing factors of fracture propagation in basement rock fractured reservoir and provide an important reference for optimization design of fracturing construction.
