Investigation on Percolation Theory and Optimization Method in Low Permeability Reservoir Injection-Production Pattern on the Condition of Fracturing

SONG Wenling, ZHAO Chunsen, XIE Zhiwui

Abstract


This passage investigates the productivity formulas in low permeability reservoir with vertical wells combined with fracturing well of the five spot rectangular pattern, seven spot pattern and nine spot pattern as well as the productivity of inverted nine-spot rhombus fractured vertical well mixed pattern. Further, the five-point rectangular patterns and the rectangular fracturing well patterns are optimized. The results reveal that widening well spacing, narrowing row spacing and changing the shape factor well network within a certain range can improve the development effectiveness, while length of the crack and area of well pattern are given, we could determine the length and width of rectangular pattern.
Key words: Low permeability; Well pattern; Productivity formula; Optimization


Keywords
