Production simulation process by pilot test in a hydrocarbon reservoir.

摘要

The invention relates to a production simulation process by pilot test in a deposit (1) of hydrocarbons contained ina reservoir (2) with the aid of injection wells (3b, 5b; 7b) and producing wells (4b, 6b, 8b) with horizontal drains, said drains forming, at least in part, a polygonal geometric shape in one plane of the reservoir. By the simulation process: a first state is triggered either by injection or by production for the drains located at the periphery of said geometric shape, a second state, opposite said first state, is triggered either by injection or by production for the drains located inside said geometric shape. the volumetric flowrates of liquid injected and produced are regulated such that the sum of the flowrates of the injection drains is substantially equal to the sum of the flowrates of the production drains.
