Adjustment Research Of Water Flooding Regime And Well Pattern On Gtz Oil Layer In Eastern Part Of B1 And B2 Of Sz Areas

In view of the actual of oil field is in high water cut later stage and ascending velocity quickly of water cut,development research on enhanced oil recovery of Water looding Regime and Well Pattern on GTZ Oil layer in Eastern Part of B1 and B2. be based on subdivided precipitation facie, applying the technique of fine description of reservoir and three-dimensional geologic model building,get a clear understanding of the situation to GTZ oil layer,dividing the employing and oil remaining of all oil layer group.research the rule and method of the Water Flooding Regime and Well Pattern on GTZ Oil layer in Eastern Part of B1 and B2,being six categories of Chinese characters,WSO,reperf and drilling at the same time adjustment Water looding Regime and Well Pattern,in order to improving the water flooding regime.Draw support form numerical analogue and dynamic analysis,optimising the case ofadjustment Water looding Regime and Well Pattern. researching the method of adjustment plane pressure field and rasing the reservoir pressure.Researching the optimize case of proration and injection allocation plan after adjustment Water looding Regime,include the water intake per unit thickness,the nature of flooding interval,the rule of water well subdivided and etc.Applying the findings of the numerical analogue,adjustment Water looding Regime,at the same time,WSO,reperf,fracture,trading pump,heavy repair,regulation parameter and etc.decreasing the STPR and adjusting the liquid producing composition.By means of adjustment Water looding Regime and Well Pattern on GTZ Oil layer in Eastern Part of B1 and B2,improving the water flooding regime,adjusting o/w well number ratio,adjustment plane pressure field,rasing the reservoir pressure,palliation the BLK natural decline and controling the acclivity speed of the water cut,expand the swept volume of the flood water utmostly,adding recoverable reserves,improving the effect of the oil field development,in order to raising the final recovery efficiency.
