Abstract

Beizhong sub-sag is a secondary fault subsidence of the Bear Lake Depression in Hailarer Basin. Horizontally the sag distributes about 800km2, and thickness of its sedimentary formation is up to 4600m. The main target formation in the Beizhong sub-sag is the Nantun formation, and the Nantun formation is classified into the low and top zones (zone 1 and zone 2), which the zone 1 is the primarily oil reservoir in the Beizhong sub-sag. This paper presents a methodology to establish the relationship charts of the lithomechanics parameters based on the log data. It will provide the theoretical guide for drilling, reservoir fracturing and reservoir reformation in the Nantun formation.
