Study On Optimization Of Different Reservoir's Enhanced Lliquid Parameters Of Qu 9 Ng3

Qu 9 Ng3 located in the southeast of Nasal structural belt of Qu.The Reservoir is controlled by fault formation of narrow Horst type reverse roof fault block.In 2012,the Reservoir has been injection and production adjustment.Now the injection-production pattern is perfect.But the production decline obviously increasing and the development effect is poor.In order to compensate the production reduce and maintain stable production,Considered that the liquid extraction measures are taken to improve the oil recovery rate.Paper apply reservoir engineering theories,evaluate the reservoir's development effects.Base on the actual condition of Qu 9 Ng3's geological and production,use the numerical simulation software and build up a large number of conceptual models.And use the ideology of orthogonal to determine the reasonable technical policy limits.In the last,based on the optimal combination of the optimal extraction technology policy limits,establishment of injection production parameter optimization model and optimization of injection and production parameters for the reservoir.Use the method of non uniform extract liquid of injection and production parameters optimization theory and methods are applied to Qu 9 the third section in Guantao Formation and compared the optimization development index,non-uniform extract liquid scheme beatty solution cumulative incremental oil 4.86×10~4m~3.Compared with the original enhanced liquid scheme,the optimization scheme's cumulative oil procuction improved 2.51%,and the water cut decreased,further il ustrates the drive for more balanced,and the effect of exploitation is improved...
