Abstract: Based on the data of logging and oil test, the vertical sealing of Paleogene faults controlling reservoir in Chaluhe fault depression of Yitong Basin was evaluated by using the method of normal pressure of fault plane. The results show that:(1) The present normal pressure of fault plane of oil and gas reservoirs can be calculated by the data of burial depth, average density of overlying strata and fault dip angle. In the Paleogene, the present normal pressure of Paleogene reservoirs in Chaluhe fault depression of Yitong Basin ranges from 13.3 MPa to 56.0 MPa, and the normal pressure during the reservoir forming period was 3.8-13.1 MPa, showing the characteristics of "ancient opening and present closing". As the greater the pressure on the fault plane, the tighter the fault, thus forming a vertical seal, otherwise open.(2) The minimum value of present normal pressure of fault plane of the reservoirs in the study area is 13.3 MPa, which is defined as the critical value of the vertical sealing of Chaluhe fault depression, and the present critical burial depth of the faults controlling reservoir is further determined to be 2 262 m.(3) The normal pressure of fault plane is positively correlated with the fault tightness index, the vertical sealing critical pressure value, critical burial depth and fault tightness index can be used to quantitatively evaluate the sealing ability of the faults controlling reservoir in the study area.(4) The fault can not only serve as the hydrocarbon migration pathway, but also provide shelter for the formation of reservoirs. The faults controlling reservoir of C43 reservoir in the northwestern margin of Chaluhe fault depression showed a vertical opening during the accumulation period, which coincided with the period of hydrocarbon generation and expulsion, with the function of connecting oil sources and migrating oil and gas. The faults controlling reservoir in well region C43-C48 are now in a vertical sealing state, which can effectively seal oil and gas.

Key words: fault sealing ability, normal pressure of fault plane, vertical sealing ability, critical pressure, critical burial depth, Paleogene, Chaluhe fault depression, Yitong Basin
