Research on the Development Law of Carbonate Reservoir Cracks in Niuxintuo West Oilfield

摘要

For the geological characteristics of carbonate reservoirs in West Niuxintuo Oilfield, using core description, well logging fracture identification, 3DMOVE fracture prediction and other new technology, the inside story of carbonate reservoir is found out under the guidance of geology, well logging, petrology and geological mechanics and other disciplines theory. On the whole, reservoir composed mainly by structural fractures has roughly three development directions that are NNW. The crack on plane mainly developed in four regions, heterogeneity of crack development in the longitudinal direction is strong. The dolomite reservoir is more developed. Research on the law of cracks provides the basis for block development and deployment of the next step adjustment.
