Definitions

  • the present invention relates to solids control generally, and more specifically, to shakers used to separate drilling fluid from drill cuttings.
  • the present invention relates to a shaker apparatus comprising at least one inertial gas-liquid separation device.
  • Solids control is used in oil and gas drilling operations, as well as in mining and other industries, to separate solids from the drilling fluids, or 'mud' used in the drilling process.
  • These drilling fluids can have several functions, including lubrication and cooling of the drill bit, as well as to convey drilled cuttings away from a bore hole.
  • the fluids are typically a mixture of various chemicals in a water or oil based solution, and can be very costly. To reduce these costs, and lessen the impact of these potentially toxic chemicals on the environment, it is desirable to recover drilling fluids from the drilled cuttings before they are disposed of.
  • Shale shakers have been used for decades in solids control processes to recover drilling fluid. They typically comprise a number of rectangular screens arranged in a basket, or 'bed', having one open discharge end and a solid walled feed end.
  • the basket is arranged to receive recovered drilling mud at the feed end, and a skip or ditch is provided beneath the open discharge end of the basket to receive solids in which fluid has been mostly removed from the drill cuttings.
  • a specialized motor, or vibrator applies a vibratory force to the shaker bed and causes the basket and screens fixed thereto to shake. Solids laden mud is introduced at the feed end of the basket on to the screens.
  • the shaking motion imparted by the motor to the basket induces the solids to move along the screens towards the open discharge end, while drilling fluid passes through the screens and is received into a receptor for further processing.
  • the present invention is directed to improvements in shale shaker technology which improves the separation process through the provision of an inertial gas/liquid separator, which functions to remove or reduce the content of certain gases that may be present in the drilling fluid.

  • the vacuum pump may in certain embodiments be adjustable to control the vacuum pressure.
  • the shaker may include a frame which holds the at least one shaker screen in position, and at least one vibrator motor operatively connected to the frame to vibrate the at least one shaker screen during operation.
