The Influence And Countermeasures Of Steam Channeling Between Oil Wells Of Ultra Heavy Oil Steam Soak In Du 229 Block

In this paper, the steam channeling mechanism of ultra heavy oil was expatiated briefly. By means of the tracking of Du 229 Block's 7 years exploitation course, the steam channeling orderliness of petroleum deposit were given primarily, the variety hurt of steam channeling were cited. The anti-steam channeling method was given associate with the production situation, and the result that the measure carries out on location was given too. During the exploitation procedure, it was found that when the oil wells enter into the middling and altitude times of rotation phase, the effect that was come into being by steam channeling is not all bad, some oil well's output were increased in different degree. Aim at this phenomenon, the"one-well injection and multi-well production"technique were adopted, and the relevant mechanism were put in practice according to the theory of steam channeling between oil wells, the better result were obtained using the measure. That exceeded the step of the quest, converted the development method for the Du 229 Block of ultra heavy oil.
