Study On Adjusting Countermeasure Of High Water Cut Sage In Bottom Water Reservoir

The Sructure of the gas-bottomed water reservoir is complex,the law of remaining oil di Sribution and tapping is difficult.At present,there are gas tops in the reservoirs,and the relatively high oil and gas characteri Sics make the development effect hard,but it Sill have the potential to tap.It is particularly important to Sudy how to develop such reservoirs efficiently.Based on the Sudy of the geological and dynamic characteri Sics of the specific fault block,this paper puts forward the comprehensive adju Sment measures of the oil field by adju Sing the development mode and the well spacing adju Sment,to improve the oilfield development effect completely.This paper Sudies the geological characteri Sics,Sructural features,reservoir characteri Sics and reserves of the block,analyzes the development Sage of the block,analyzes and evaluates the development Satus and development effect of the block,and applies the reservoir engineering method and digital mold technology,fitted the reservoir pressure,yield and comprehensive water content,and the remaining oil rules were summarized.This paper summarizes the problems in the development of a block in Tarim Oilfield: the low utilization rate of reserves;some development units are currently no production,the remaining oil can not be used;some oil wells development technology policy unreasonable water fa S rise;the oilfield rate of decline is high.Combined with the remaining oil di Sribution characteri Sics to adju S the well spacing,to determine the reasonable formation pressure to maintain the level of production pressure,oil recovery rate,perforation position.On the basis of the Sudy of the development of technical boundaries,three sets of adju Sment schemes are designed,and the scheme is directly compared.In this paper,through reservoir numerical simulation,reservoir dynamic analysis andother technical means to re-under Sand the reservoir,anatomical reservoir,Sudy on evaluation and adju Sment of reservoir development effect,to achieve yield,Sable production,improve the development effect,improve the level of development purposes.
