The Function of Drilling Mud
Essentially all tricones for sale these days assume use of drilling mud for lubrication, but past that drilling mud has several other crucial purposes. Removing the cuttings from the well is the most important aspect quality. Like a stream can carry flotsam downstream, drilling mud carries cuttings and debris away from the tricone or other drill bits in use. Additionally drilling mud acts to maintain a controlled of pressure in a borehole. As tricone go deeper through formations the levels of pressure may increase, which requires increased mud density. This has the added effect of improving wellbore stability, allowing a borehole of consistent size and shape. Drilling mud also has the important task of suspending debris if the tricone comes to a stop or drilling has to be halted for any reason. Although most modern tricones for sale today rarely jam or need replacement when used correctly, you may still need to halt drilling several times over the course of an extensive project.
The Properties of Drilling Mud
The makeup of drilling mud can be altered to meet the various functions outlined above, as well as catering to the different drill bits or tricones for sale on the open market. The viscosity of the fluid can be tailored to match the size and density of cuttings expected. Related to this, the thixotropy of a drilling mud is crucial. On a technical level, thixotropy refers to a property of gel or fluid to become more or less viscous depending on the amount of energy being transferred to that fluid via sheer stress. Essentially, the kinds of tricones for sale today can rotate with enough force that sufficiently thixotropic mud becomes liquid and is able to flow and move more easily, when the force stops (when drilling is halted) the mud becomes more solid and is able to suspend cuttings and debris. Modern tricones for sale to drilling companies tend to employ some level of bearing protection which dramatically reduces the potential damage from debris in this situation, but any potential slowdown in a large scale project is a risk that ought to be avoided.
Finding the Best Drilling Mud for Your Project
As with many questions in well drilling, there is no easy. In fact, firms responsible for drilling employ mud engineers specifically because of the complexity of creating the perfect mud that balances viscosity, density, thixotropy, and pressure of the mud. Drilling mud can be expensive in its own right, and can have a large impact on the rate of drilling and therefore the overall cost of the project. Selecting the right mud available is almost as important as selecting the bit from among all the tricones for sale. Do not cut corners when it comes to drilling mud.
