METHODS AND SYSTEMS FOR CHARACTERIZING LCM PARTICLE PLUGGING AND RHEOLOGY IN REAL TIME

摘要

Methods and systems for characterizing drilling fluids laden with LCM (Lost Circulation Material) are disclosed. A test cell (106) for analyzing a fluid is provided with a conical inner portion (306) and an axial positioning device (304) positioned along an axis of the test cell. A conical plug (302) is coupled to the axial positioning device and is movable in and out of the conical inner portion along the axis of the test cell. A fluid inlet is positioned at a first location on the test cell and a fluid outlet at a second location.
