The Research And Application Of Composite Sealing Plane On Ultra Heavy Oil Reservoir

Since the super heavy oil to invest in developing well between steam channeling onrestricting oil field development, the principal contradiction with the expansion of the scale ofdevelopment, an oil throughput of rounds increase, as well as edge and difficult to use toblock production wells, steam channelingmore prominent contradiction between theincreasingly serious impact on production, steam channeling energy spillover of steaminjection wells, the lower utilization of steam heat. The steam channeling will cause thereservoir heating seriously uneven, cause steam to spread small size, low thermal efficiency,throughput is poor; the formation of steam channeling channel further exacerbated by the useof uneven contradiction; minor by effective channeling wells production rate, affecting theyield. Steam channeling caused by the channeling well fluid production increasedsignificantly, the sharp fluctuations in oil production, the production is not running smoothly.Severely affected by the channeling Well the bad sets, resulting in well scrapped. Serioussteam breakthrough may lead to disturbed well blowout pollution accident, the damage ismore and more serious. Even more serious is that the steam channeling will lead tochanneling wells set a bad shut-in.Shu a super heavy oil block reservoir characteristics, oil properties, and production fromthe start, steam channeling law studies and impact analysis of the factors to determine the nextstep measures the direction of ultimately optimize the scope and technical parameters of theselected wellpurposes, in order to guide the field application, to improve the effectiveness ofmeasures.The success of the study, scientific and reliable first-hand information and technicalsupport for the ultra-heavy oil blocks in the dawn of the oil field development, thedevelopment of extra heavy oil from other oil fields at home and abroad also has somereference.
