Study On The Development Geology Of Oil Field In Sudeerte Buried Hill

Beier depression is located in central and southern area of Hailaer Basin, between the Cuogang uplift and Bayanshan uplift. Sudeerte structural belt is between the Baertaolegai and Aonaohai depression which is located in the middle of Beier depression, it spreads in the direction of the North East.As the time finding reservoir in this area is later, the information available is limited, the geological understanding of the buried hill reservoir, such as the distribution of oil and water, the type of reservoir, formation mechanism, development and distribution law of the reservoir hole - hole - the crack etc are not entirely clear.Therefore, this study utilizes sufficiently existing seismic, logging, drilling and test data to study the development and distribution of faults in Sudeerte hill reservoir, to evaluate vertical and lateral sealing of the 21 typical faults within the reservoir; to study development characteristics and influencing factors of cracks within the reservion, to study the plane and profile distribution of cracks, and uses existing wells data to verify the studying results.By the former work , the location of the oil-water interface is determined; on the development and distribution of oil reservoir have been studied; distribution law of oil-water and influencing factors were studied; the type of oil reservoir and its distribution were studied.
