Abstract
In view of the high viscosity of drilling fluid, difficult pipe tripping and hard control of drilling fluid rheology in a highly deviated well of a block in Liaodong Bay, a new technical method is put forward that starting from cuttings bed re-moving, on the basis of the improvement of mud cake quality to ensure a smooth borehole, stable borehole wall and effective cuttings carrying, the rheology of drilling fluid is controlled to be turbulence at the drill collar so as to the cuttings uniformly dispersing in the drilling fluid to reduce the formation of cuttings bed.In this block of Liaodong Bay, this technology is used in 8 wells with the horizontal distance and vertical distance ratio of less than 2, the ideal effects are obtained.关键词
