| Abstract: | Due to the low initial productivity and the easy gas-channeling and water-coning during vertical-well development of oil reservoirs with gas cap,it has been proposed that horizontal wells can be used to develop reservoirs with big gas cap and narrow oil rim,and the numerical simulation researches have been conducted on several key aspects,such as length,orientation and vertical depth of the horizontal holes and oil production rate and development style of the horizontal wells.The practice of horizontal-well... |
