Variation of Water Content in Plugged Layers and Pre-diction Methods
-
Abstract
More and more intervals in producers are plugged and the time is also becomes longer as oilfields enter into high water cut stage of development, resulting in change of water pressure gradient and redistribution of the remaining oil in the plugged layers. Grey theory is used to predict variation of water content in the plugged intervals in wells with high water cut, and calculate production through unplugging.
