Experimental Study on the Flow Field Distribution Law of Ultra-Low Permeability Reservoir with Inverted Nine-Spot Equilateral well Pattern

Abstract:

Aimed at ultra-low permeability reservoir, the large natural outcrop model has been made for researching the oil reservoirs porous flow law deeply, and the inverted nine-spot equilateral well pattern also has been designed which is the commonest well patter during the oilfield exploitation. The flow fields have been measured during the experiment in different displacing period (0.3PV, 0.6PV and 1PV). The research shows that fluid flow has obvious directivity, and it strongly affected by heterogeneity of the reservoir. In addition, the regions between the edge production wells are much more difficult to be exploited.
