Low permeability and extra low permeability oil field in our country is a large proportionof. Because of the rapid development of economy, more and more high demand for energy, sothe energy shortage problem has become increasingly prominent, high grade reservoir dwindle,large-scale mining rich reserves of low permeability, ultra-low permeability reservoir has beencrunch time, be imperative. Very good solution to this problem, can make an effort andcontribution to alleviate the shortage of domestic petroleum resources. The current in thewater under the condition of low permeability oilfield produced the highest degree of not morethan25%, mostly below9%without water. Use what kind of method and means to theexploitation of low permeability oil field, enhanced oil recovery, is a challenge of PetroleumTechnology workers. Early often uses the experience way to determine the development blockpatterns, this method uses similar block matching to establish its development mode, becausethe property a few blocks, reservoir forming mechanism can not completely consistent, so latein the development mode adjustment is relatively more; then put forward numerical simulationto study the dynamic production and block reasonable development mode. The numericalsimulation with the more software ECLIPSE, the software SimBest II, VIP, CMG, Eclipsesoftware is recognized at home and abroad using the most comprehensive function, theinternational first-class software. The use of many Eclipse software function, can effectivelysolve many problems emerge in reservoir research, the operation results of the3D displayfunction allows reservoir engineers can intuitively understand the various physical parametersof reservoir structure and reservoir in morphology, But in three-dimensional space; and thechange of oil formation, in the production process of water cone the middle of the watersaturation and pressure field, very good to improve the understanding of the end of oilproduction of remaining oil reservoirs in the oilfield, greatly promote the developmentpotential of the work has been put into operation.
