Research On Physical Properties Change Of Later Stage Of High Water Cut Reservoir

With the deepening of oilfield development, great changes have taken place in thephysical properties of the reservoir, practice shows that the adjustment well drilling,cementing quality changes of physical properties of the reservoir layer of new drilling causedgreat impact. At present, oilfield has entered the high water cut stage changes of reservoir,and this change impacts on drilling cementing larger. In recent years, in view of theseproblems the corresponding research work, but for the influence of physical property ofreservoir understanding of cementing quality in the qualitative stage, lack of quantitativeresearch. Study on the variation of reservoir properties and corresponding cementingtechnology program will be there search direction to improve the cementing quality in the latestage of oilfield development.The Daqing reservoir of Changyuan first oil company, second company, third company,sixth company are analyzed, the physical property north, on the basis of the research on theinfluence factors of cementing quality in late stage of high water cut reservoir physicalproperties change and new injection of factors on the cementing quality medium, carry out aseries of indoor and outdoor experiments, analysis of a large amount of data, the influence ofvarious parameters to determine factors cement bond index, completed a preliminary modelinto the mechanism of effect of medium on cementing quality...
