Distributing Of Remaining Oil And The Method Of Developing In The Second Type Oil Layers Reservoirs

At the present time,with the rapid development of study on the remaining oil distribution ,we have scored great successes. The second type reservoir dominated by delta plainand and delta front,the scale of channel sandbody is small, the number of layer is more , the thickness of sandstone is thin, permeability is low and heterogeneity is severe. Developing remaining oil still has lots of extremely difficult in the second type reservoir. The exploitation of second type reservoir formed relevant technologies in the North of Saertu Development Area for the last two years. Comprehensive adjustment will be developed integrated. This study we describe accurately the remaining oil distribution and the origin types and features in the second type reservoir according to particularly analyze the material of static and dynamic state. And find the major affection factors to remaining oil distribution. Against different kinds of remaining oil distribution study auxiliary technology. The results are significan and it has a good prospect to be widely used in Daqing Oil Field.
