void type
5.Combined with such as the seismic, well-logging data, core, FMI imaging logging data, the paper evaluates the reservoir of Ordovician in Ka 1 block, and designates tow type reservoir rock: dolomite, limestone and four type reservoir:dissolution-void reservoir, dispersive fracture reservoir, fracture-void reservoir, vertical fracture reservoir. Thereinto, dolomite of middle-lower Ordovician reveals be mostly fracture reservoir, limestone of upper Ordovician reveals be mostly dissolution reservoir.
