目前喇嘛甸油田一类油层后续水驱采出程度达55%以上,但剩余油仍具有潜力,如何开发一类油层聚驱后的剩余储量,进一步提高主力油层采收率,是目前油田亟待解决的问题,也是保持油田可持续发展的重要环节,而选择哪种措施进一步提高采收率,又决定于聚驱后剩余油分布情况。因此选择已经进入后续水驱阶段的喇北西块一类油层作为研究对象,探索主力油层聚驱后剩余油分布规律,为挖潜这部分剩余潜力提供依据。
At present, the oil recovery of the first type reservoirs in Lamadian Oilfield is more than 55%, but the residual oil still has potential. How to develop the residual reserves after the first flooding in the oil reservoir and further enhance the recovery rate of the main oil reservoirs is the urgent need to be solved Of the problem, but also to maintain the sustainable development of the oil field an important part of the choice of what measures to further enhance oil recovery, but also determined by the remaining oil distribution after flooding. Therefore, the oil reservoirs of Lhasi West Block, which have entered the subsequent water flooding stage, are selected as research objects. The distribution of remaining oil after the flooding of the main oil reservoirs is explored to provide the basis for tapping the remaining potential of this part.
