Abstract

Abstract: The depletionmethod is themost reasonable method to exploit fracture-vug type carbonate reservoirs. In the case of developmentby depletion, it is especially important to determine a reasonable oil recovery rate when stablishing reasonable development plan. In this paper, according to successful development cases ofother similar fields, many affecting factors are taken into account and multiple-stepwise-regression analysismethod is used to derive a reasonable oil recovery ratemodel of fracturevug type carbonate reservoir in the early development period.Thismodel includes fluid properties and reservoirparameters and is consistentwith physical concept that indicates inherent geological conditions'effect on oil recovery rate. It can bewidely used and draw a primary conclusion on reasonable oil recovery rate of fracture-vug type carbonate reservoir in the early depletion developmentperiod. Numerical simulationmethod is used to prove that thismodel is applicable to field practice.

Key words: recovery rate, fracture, vug, carbonate rock, multiple regression, stepwise regression
