A Research Into Steam Channeling Mechanism And Prevention And Control Measures Of Jin 91 Block

In the steam flooding exploitation phase,with time extension and strata pressure pressure drop, the steam channeling phenomena has become serious. The steam channeling currently has become an important factor affecting on stable production of Jin 91 piece. To enhance thick oil recoveries, on the basis of its simulation experiments, Jin 91 block away from rational exploitation wells to 100m, with the oil deposit from wells comprehensive adjustment measures implemented from 1997 to date for the implementation of net wells during encryption, The encryption 118m to 183m, Chouyou steam prices in the exploitation phase, with the extension of mining, Surface pressure drop in gas escape from the growing phenomenon seriously affected blocks the effects of mining, How to prevent steam escape, Ensuring effective exploitation wells and improve the recoveries started oil deposit into production oilfields important topic. Authors from production reality in analyzing fuel stocks in essence, The use of the current technology status, And integration with the main suspects to take the same note with a chemical letters away and the closure of steam carrying wells, And other technology transfer activities conducted letters everywhere, paved Note steam-run, One more note a regional Note Company, stratified Note Company, Intermittent Note Company, And other means of Kam-91 started implementing comprehensive management,Started to improve the effectiveness of development played a certain role to see significant economic impact, The governance steam away from the conclusions of Chouyou oil deposit exploitation and steam away with experience.
