Abstract

Abstract: The optimization-of perforating parameters for improvingwell performance in naturally fractured reservoirs is quite differ-ent from that of conventional sandstone reservoirs. The produc-tivity evaluation of perforated oil well becomes very complicated in the presence of natural fracture in reservoirs. In this paper,the effects of perforating parameters ort well productivity for dif-
ferent fracture network configurations , including one set of trans-verse fracture , one set of vertical fracture，two sets of vertical fractures and three sets of mutual perpendicular fractures, were analyzed and discussed in detail on the basis of mathematical modeling of well productivity by the finite element method. Some useful results have been obtained, and the software.of optimal
design for perforating parameters in naturally fractured reservoirs was developed. It is very nutritious to direct the operation of per-forating completion in natural fracture reservoirs and thus en-hance the well performance.

Key words: fracture reservoir, perforation, finite element, optimization productivity ratio
