Abstract: The reservoir heterogeneity of Triassic Baikouquan Formation in northern Mahu Sag of Junggar Basin is strong,and multi factor comprehensive analysis has become an important means of fine reservoir research in recent years. Through core description,casting thin section,logging curve and grain size analysis,the studies on petrophysical facies including reservoir sedimentary microfacies,diagenetic facies and fracture facies were carried out,and cluster analysis on the divided petrophysical facies was carry out to predict favorable reservoirs in the study area. The results show that:(1)Fan delta sedimentary microfacies are mainly composed of distributary channel, braided branch channel,underwater distributary channel and underwater distributary bay.(2)Diagenetic facies include three kinds of tight diagenetic facies(compacted tight diagenetic facies,illite/smectite filling diagenetic facies and siliceous cementation diagenetic facies)and two kinds of dilatancy diagenetic facies(chlorite lining weak dissolution diagenetic facies and unstable component dissolution diagenetic facies).(3)Under the background of gentle slope,the fracture density is less than 1/m due to the local development of horizontal fractures, which has little impact on reservoir physical properties.(4)According to the superposition principle of "sedimentary microfacies + diagenetic facies + fracture facies",the classification of petrophysical facies was determined, and 10 kinds of petrophysical facies were divided,such as underwater distributary channel-chlorite lining weak dissolution diagenesis facies and so on.(5)PF1 corresponds to type Ⅰ reservoir,with the best reservoir physical properties,mainly developed in Bai 2 member,and the development scale of the Bai 3 member is relatively small. PF2 corresponds to type Ⅱ reservoir with medium physical properties and relatively developed in Baikouquan Formation. PF3 corresponds to type Ⅲ reservoir,with relatively poor physical properties and relatively developed in Bai 3 member. The research method of petrophysical facies in northern Mahu Sag can provide guidance for oil and gas exploration of Baikouquan Formation.
