Dynamic regulation of steam drive technology and its application in Qi 40 block wells group

In the implementation process of the first industrial steam drive of 65 wells group in Qi 40 block,in order to a-chieve the efficient and healthy development,fully considering test area experience,this paper studied its temperature and vapor chaber and carried on dynamic regulation from four aspects as the temperature field,well network,vertical steam and steam suction respectively,which has achieved good development results and provided reference experiencefor later drive switch 74 wells group of the block.
