Abstract:
The study area is low porosity,extra-low permeability,thick-massive conglomerate reservoir with fracture.By using numerical simulation method,the author carried on the research on the well pattern and formal water injection occasion,and determined the development mode suitable for the studied area with the application of orthogonal design and and economical evaluation.That is reverse nine-sport turn-ing to fivesport water flooding pattern with 135M well space,30 m3/d daily water injection and 85% water content in formal water injection.
