To analyze the effect of various flow units in a channel sand body on remnant oil, we established a connection between various flow unit types and the remnant oil distribution.
Using stratigraphic correlation and the characterization of sedimentary microfacies, we describe a single sand body, point bar, and narrow channel located at the injection-production well pattern of well B2-60-FB271 in the Eastern transition zone of the Daqing Placanticline.
Architecture models of the point bar and narrow channel are also established using a series of parameters from different measurement methods.
Four types of flow units (strong-current limiting, medium-current limiting, weak-current limiting, and none-current limiting) in the point bar sand body were identified, whereas one type, unshielded unit, was identified in the narrow channel.
Geological parameters, such as porosity, permeability, and pore-throat radius (r50), were optimized to quantitatively characterize these various flow units.
Samples were obtained from well B2-60-FB271 and analyzed by the freeze-fluorescence thin section technique.
According to the displacement degree, the microscopic remnant oil was divided into three types: (1) free-state remnant oil, (2) semi-free-state remnant oil, and (3) bound-state remnant oil.
We found that the strong-current limiting flow unit in the point bar is the enrichment area of free-state microscopic remnant oil and that the medium-current limiting and weak-current limiting flow units also have relatively high free microscopic remnant oil.
These constitute the remaining oil enrichment areas in the study area.
