Mud gun is the agitation or mixing device. Usually we operate them together with mud agitator.

Mud guns general information

Both high-pressure and low-pressure mud guns agitate mud by means of rapid fluid movement through a nozzle. Pressure and flow are delivered via either high-pressure main mud pumps or, most often, centrifugal pumps. There are two points of view as to where pumps for mud gun should draw suction from: (1) the compartment that they stir or (2) a compartment downstream, ideally immediately after the last solids control device.

Different option effect for mud gun

Consider option 1 (drawing suction from the compartment to be stirred): When mud guns are placed in compartments that are designated for solids-removal equipment (e.g., hydrocyclones, centrifuges), the Suspension, Agitation, and Mixing of Drilling Fluids possibility of pumping solids-laden fluid exists.

Continuous circulation of solids-laden fluid (especially sand) will result in faster wear on pump parts and mud gun nozzles. Manufacturers provide nozzle inserts made of wear-resistant plastics to increase life and reduce replacement costs If parts are not replaced when needed, agitation efficiency decreases Another argument against pumping into the same compartment from which suction is drawn is the possibility for particle size degradation which will also reduce solids-removal efficiency and force use of more costly solids-control mechanisms or dilution. Option 1 is feasible if used in compartments downstream of the last solids-control device, provided the upstream solids-control system is properly designed and operated.

Option 2 (drawing suction from a compartment downstream of the solids-control system) is more desirable for two reasons. First, it prevents continuous circulation of fluid that may be laden with drilled solids assuming efficient upstream solids removal. This maintains mud gun efficiency and reduces wear to fluid-end pump parts. Secondly, it places cleaned fluid into the compartment to be stirred. This is especially effective when solids concentration is high or fluctuates (e.g., high penetration rates and/or sweep returns to the surface). However, option 2 necessitates more process capacity from the solids-control equipment (including the degasser and hydrocyclone compartments). Rig circulating rate and flow through mud guns must be added and then accounted for.

Mud gun design

There are many different design of mud guns. The high pressure, low pressure, the mud gun with one nozzle or 3 nozzle. The nozzle size is 2" or 3", meanwhile, we can find the mud gun with handle or hand wheel operator. No matter which design or dimension as well as the surface color please tell us your demand. We'll provide the ideal option for you.
