The Central East To Polymer Flooding Oil Well Group Different Injection Parameters

The central east development zone in the implementation of old oil fields in the second development project,the central western as the first implementation of secondary development project capacity building blocks,according to the ground,underground "the overall research,unified deployment,synchronized advancement,comprehensive,balanced and" the second development policy,formulate the development countermeasures.Deployed to tertiary oil recovery,oil,Portugal,the Portuguese "two series" three kinds of reservoir,high counter three sets of the adjustment of reservoir development pattern,and compiled three sets of well pattern of reservoir engineering plan.Among them,the central west Portugal to tertiary oil reservoir engineering design of oil Wells.A group of Portuguese central east main reservoir after polymer flooding,the oil company "12th Five-Year" during the three production of two categories in the implementation of all polymer flooding requirements,complete the central eastern two reservoirs in three oil reservoir engineering plan prepared in May 2011,according to reservoir engineering design in central eastern section is divided into three sections combined development.The first mining segment II ~ III 10.SA 10 SA block area of 7.28km2 oil,oil and water wells 422,206 note 216,from 125 * 133 m.shot 18.0m injection wells sandstone thickness,effective thickness is 10.3M,the average effective permeability of 0.5 72 m2.,according to planning arrangements,blocks drilling in November 2011,infrastructure,in June2012,put into operation,into the blank water flooding,is expected to implement two types of oil reservoir polymer flooding in October 2013.
