conglomerate oil reservoir in block 530 of Karamay oilfield namely; seismic phase

well testing phase as well as data collected from analysis of the rock cores etc. are used in setting up a succession indicator simulating reservoir sedimentary model and the semi-Markov simulating space distribution of reservoir property parameter either in consideration of sedimentary history or in consideration of sedimentary mechanism to simulate respectively sediments in the study area and characteristic parameters of reservoir physical property. It can be obviously observed from the static model of reservoir sedimentary facies established by setting up a succession indicator simulating reservoir sedimentary model that ancient waterflow entering sedimentary area from upper left part

and where subfacies of middle part of the fan and edge of the fan in the downdip block of the fracture deposit and subfaices of the fan top is absent

but saturation of oil content is on the contrary. It is believed by simulating predication that parameters of the reservoir physical property near the west section of Ke-Wu fracture zone is better than that of other sections
