a stator and a rotor for transferring introduced liquid, a rod and a pin for eccentrically driving the rotor, a driving shaft and bearings, and an end piece. 1.2 Operation Principle The operating part of the displacement-screw type Pump is, as shown in Fig.1, a simple combination of a stator (001) with a double-thread screw and a rotor(101)
When it comes to horizontal directional drilling (HDD), the mud system weight plays a crucial role in the success of the operation. The unit weight of the drilling mud used in HDD projects needs to be carefully monitored and maintained within a specific range to ensure optimal performance. On Feb 5, 2018, it was emphasized that the unit weight needs to be within a range between 9 and 10 pounds per gallon. This is essential for various reasons, including preventing the flow of formation fluids into the hole and ensuring the stability of the borehole.

Drilling Mud in HDD
Drilling mud, also known as drilling fluid, serves multiple purposes in HDD operations. One of its primary functions is to provide hydraulic support to the borehole walls, preventing collapses and maintaining stability during the drilling process. In addition to this, drilling mud also helps to cool and lubricate the drill bit, carry cuttings to the surface, and seal off permeable formations to prevent fluid loss.
Achieving the right unit weight of the drilling mud is critical for the success of the HDD project. The ideal range of 9 to 10 pounds per gallon strikes a balance between providing sufficient hydraulic support and preventing excessive pressure on the formation. Water, with a unit weight of 8.34 pounds per gallon, serves as a benchmark for comparing the density of the drilling mud.
Mixing the Mud in HDD
Mixing the drilling mud to achieve the desired unit weight requires precision and careful attention to detail. Various components, such as bentonite, polymers, and weighting agents, are added to the base fluid to adjust the density of the mud. The mixing process must be carried out systematically to ensure uniform distribution of the additives and consistent properties throughout the mud system.
Properly mixed drilling mud not only helps to maintain the desired unit weight but also enhances the overall performance of the HDD operation. A well-designed mud system can improve drilling efficiency, reduce downtime, and minimize the risk of borehole instability. Regular monitoring and testing of the mud properties are essential to ensure that the unit weight remains within the specified range.

A twin screw pump is a type of positive displacement pump that consists of two intermeshing screws within a chamber. As the screws rotate, they move the fluid through the pump and create a vacuum at the inlet and pressure at the outlet.
