Evaluation and optimization of well patterns designed for banding faulted block reservoirs with extremely low permeability
摘要
Abstract
Flooding patterns optimization is one of the key technologies for developing faulted block oilfields with extremely low permeability effectively. Considering the geometric characteristics and the size of banding faulted block oilfields, 13 well patterns were designed. Referring to the geologic parameters and production performance in Block Hual7, all of the 13 well patterns were evaluated by applying the nonlinear flow numerical simulation software which designed for such kind of reservoir, and by comparison 3 optimal patterns were provided. The optimization results indicated that: for the banding faulted block reservoirs which could accommodate 3 rows of vertical wells, the optimal pattern was one row of injection wells between two rows of production wells; for the reservoirs which can accommodate 2 rows of vertical wells, the optimal pattern was the one with one injection well working for 3 production wells aver-agely; and for vertical-horizontal-combined patterns, the optimal location of the vertical injection well is the periphery of the horizontal production well's hoe.关键词
