Working principle and performance of drilling fluid shale shakerThe drilling fluid shale shaker is the primary solid control equipment in the drilling mud solid-state control system, which handles 74% of the mud returned from drilling μ M to ensure the treatment effect and service life of the following equipment with large drilling cuttings in the mud. There are many shapes and specifications of drilling fluid shale shaker, including linear screen, arc screen, flat screen, single layer, double layer and three layers, as well as single screen, double screen and triple screen. Drilling fluid shale shaker generates linear motion, circular motion or translational elliptical motion track through excitation beam under the action of eccentric block force. The two exciting motors rotate in opposite directions, and the exciting forces generated by their mutual operation. The exciting forces of the two motors are superimposed on each other, so as to drive the reciprocating movement of the whole up, down, left and right directions. At the same time, the mud on the screen surface moves along the track direction, and then it has moved forward when it falls freely. In this way, it is constantly thrown up and down to make the mud move forward, The mud leaks into the mud tank through the screen, and 74% of the mud is in the mud μ M is screened out with larger drilling cuttings and solid particles, which plays the role of mud liquid-solid-liquid separation and purification. The drilling fluid shale shaker is mainly composed of base, screen box, screen, logging tank, excitation motor, damping spring, control switch, regulating device, etc. Drilling fluid shale shaker is one of the indispensable equipment in oil drilling solid control system. It has the characteristics of compact structure, high work efficiency and convenient maintenance. The second and third level solid control equipment mainly include drilling fluid cleaner, drilling fluid desilter, drilling fluid desander, drilling fluid vacuum degasser, drilling fluid centrifuge and other equipment.
