The Way of Solving Drilling Bit Blocked by Mud

If the mud pump is delivering 464 liters per minute and we know that our annular has 70 liters per meter then we can calculate the speed or velocity that the mud is travelling up the hole. So now you have an idea of the speed at which the mud is travelling up the hole. If you are unsure of what capacity your mud pump is giving then measure the flow coming out of the bore hole by timing how long it takes to fill a container with a known volume in liters.

We are always drilling with mud pumps that are too small for the diameter that we want to drill. For example a very common size of mud pump used is the 5” x 6” portable rock crusher water well drilling rig price, which has a 5” diameter piston and a 6” stroke. This pump will deliver 580 liters per minute at maximum rpm. So for practical purposes you are looking at about 80% of this figure which will be around 464 liters per minute. To calculate your annular volume per meter you need to deduct the volume of the drill rods from the volume of the hole. To calculate the cylindrical volumes in liters use the formula in centimeters.

You must ever block your bit off when drilling with mud and when you pull out you find that the bit and the first one or two drill rods above the bit are full of sand. To avoid these set of circumstances you should consider the following:
