SYSTEM AND METHODOLOGY FOR EVALUATING FRACTURE NETWORKS

摘要

A technique facilitates the study of complex fracture networks. A slot manifold is constructed with a system of branched thin channels, e.g. slots, which are joined at intersections. Fluid is flowed through the system of branched thin channels and through an intersection or intersections joining the channels in a manner which enables evaluation of fluid flow. A flow distribution device is used to allow or block flow of the fluid along specific branches of the system of branched thin channels to facilitate evaluation of fluid flow as a fluid moves through various angular changes and/or flow gap width changes from one channel to another.

1. A system for studying complex fracture networks, comprising:
a slot manifold having:
a plurality of slots sections connected together at angles with respect to each other, each slot section being formed by parallel plates having a flow gap there between;a flow distribution device engaging the plurality of slots sections, the flow distribution device being selectively adjustable to allow or block fluid flow along the flow gap of selected slots sections of the plurality of slots sections; anda plurality of fluid flow inlets and outlets to enable inflow and outflow of fluid with respect to the plurality of slot sections to simulate fracture network flow between fractures oriented at a plurality of different angles with respect to each other.
