For incomplete wells, because steam breakthrough is a comprehensive reflection of various influencing factors, so the high value of certain factor may not definitely indicate a serious breakthrough.
As above description, X4303, X44021 and X4404 are complete breakthrough wells and the other four wells belong to incomplete breakthrough well.
So the CIP values of these wells might be lower than 0.5 and they can be regarded as incomplete breakthrough wells; for wells with low water cut and high temperature, the degree of breakthrough may also be low and the CIP value is lower than 0.5, so these wells are also regarded as incomplete breakthrough wells; for wells with low water cut and low temperature, no breakthrough happens.
In summary, the precise relation between the calculated breakthrough volume and the numerical simulation results for complete breakthrough wells and incomplete breakthrough wells needs further study.
Based on the tapering distribution of the steam breakthrough channel, blocking parameters considering oil drainage radius around the injector, temperature distribution between the injector and the producer and the demand of blocking effect and field reality are obtained to calculate the blocking volume for complete breakthrough wells and incomplete breakthrough wells.
For the incomplete breakthrough well, the breakthrough radius is smaller than the well spacing, and this may lead to the calculated breakthrough area being smaller than the real steam and condensate water area.
Photography is an easily manipulated medium, and a very incomplete — as well as a very wonderful — way of examining the world.
Nevertheless, scientists do accept lawlike statements on the basis of only incomplete, as well as indirect, verification which is what "confirmation" amounts to.
Was it wise to go to war? Was it the right thing to do?"For those with an appetite, the paper-trail assembled by the NSA, though necessarily incomplete, is well worth looking at.
Remaining oil caused by incomplete waterflood well pattern cannot be swept effectively.
