The Baer Depression Tuffaceous Sandstone Reservoir Characteristics and Logging Response Research Status, Problems

Abstract:

In logging field, saturation evaluation in tuffaceous sandstone reservoirs has been a difficult issue to be solved urgently. It is mainly due to the effect of complex pore structures in tuffaceous sandstone reservoirs. Compared with the normal sandstones, the tuffaceous sands have the properties of diversity origination, complex mineral components, easily transformed mineral, complex digenesis and porosity evolution .The comprehensive analyses of cores, thin slices, SEM, mercury-injection data and former research outcome of Beier oilfield on the porous structure and reservoir physical property of sandstones. The tuffaceous alteration is different under different burial phase and diagenetic environment and has different effects on the porosity of coarse grain have a constructive affection to the secondary porosity.
