The Perferrde Of Injection Well Profile Control In High Temperature Reservoir Of Renqiu Oil Field

As the limitations of regular tune-drive technology for high-temperature reservoir inNorth China Renqiu use. In this paper, through a large number of data research, found thatthere was not a particularly suitable for high temperature Sandstone Reservoir FloodingTechnologyT due to high temperature (120degrees C)，the reservoir flooding technology isalways a difficult problem to be solved. Through field investigation, found that the currentNorth Renqiu oilfield lfooding technology focused on crack closure, which ignores theflooding agent in the matrix on the oil displacement cffcct? leading to profile control, oildisplacement effect is not ideal，which largely affects the oil recovery degree. Thereofre? inNorth China Renqiu oilfield reservoir characteristics and development trends, this paperoptimized the corresponding compound flooding t the proifle control technology withchemical flooding technology cffcctivcly combined t thereby improving oil recovery of a newtechnology, this technology rfamework’ according to the characteristics of the reservoir,proifle control flooding system adaptive analysis’ select the most suitable compound floodingsystem, at the same time, through the current flooding problems in the process of analysisand study, on the flooding measures to optimize the process parameters? the selection of aset of suitable for high temperature sandstone reservoir flooding, this study for either noproifle treatment of oilifeld is more effective to improve the recovery rate of，’ or for theprofile control atfer a further increase oil recovery has important realistic significance.In this paper, atfer completion of the indoor study stage work， in the north of Renqiu oilfield factory Xiliu block10chose4injection well conducted a field pilot test, the measures andefleets of screening, can see a multifunctional composite oil-displacing system good heatresistance， and can keep a long time stability at the same time， the optimized processparameters can make the flooding effect is more obvious.
