摘要
为了解决全油基钻井液在钻井循环过程中发生的重晶石动态沉降问题,通过测量抗高温全油基钻井液流变性和动态沉降密度差,对钻井液动态沉降密度差与单独流变参数之间关系进行研究,确定钻井液动态沉降密度差与塑性粘度关系不密切,而与影响钻井液结构特性的流变参数R6读数,动切力,终切力关系密切.采用统计软件R建立了钻井液动态沉降密度差与钻井液R6,YP和终切力关系模型,为现场钻井液工程师调控钻井液动态沉降密度差提供途径.
In order to solve the problems of the dynamic sag of all oil-base drilling fluids in drilling cycle, in this paper, by measuring the rheological properties and the dynamic sag of high temperature all oil-base drilling fluid , we have discussed the relationship between the dynamic sag and all rheological properties.and have the effect that the dynamic sag of aii oil-base drilling fluids is not correlated with the plastic viscosity, but is related to R6, YP, Gel10min, The statistical software R was adopted to construct the relation model between dynamic sag of all oil-base drilling fluid and R6, YP and gel, for the drilling engineers control drilling fluid density difference with dynamic subsidence.
