Prediction Of Carbonate Reservoir Under Salt Bed In The Thrust Belt

Carbonate formation,as a traditional high quality reservoir,is famous for its high yield.But in the carbonate formation with little corrosion action,how to correctly identify the other favorable factors is the key to the prediction of carbonate reservoir.The carbonate rocks of the reverse thrust belt have such characteristics,that is,the dissolution of carbonate strata is less,the reservoir type is mainly the fractured reservoir,and there are a small range of reef.This makes it even more difficult to predict the reservoir in the carbonate formation under the salt of the thrust belt.If we want to predict this kind of reservoir by geophysical means,we need to start with the main control factors of reservoir,and predict the favorable aspects of reservoir.In this paper,firstly,study on the sedimentary characteristics and tectonic deformation characteristics of the area.To define the development pattern of organic reefs and fractures in this area.And then select a more typical study area.In this area,on one hand,distinguish fracture in the well from imaging logging and conventional logging data.On the other hand,identification of reef flat body distribution by seismic attribute data.And then,draw them through impedance body in 3D area.Expect to use mixed advantage of reservoir in 3D area.More accurately portray the thrust belt of carbonate reservoir.And finally,form a suit of methods and processes to predict the reservoir at the thrust belt of carbonate rock.
