Piston Oil Drilling Rig Mud Pump

Drilling Rig Mud Pump Description:

The BW-250 grouting pump is a horizontal three-cylinder reciprocating single-acting piston pump. The pump has two bore and four speeds. Large bore (φ80mm) can be used as a supporting equipment for 1000m large-diameter drilling rigs. Small bore (φ65mm) can be used as a supporting equipment for 1500m small-aperture drilling rigs. Both bores have four displacements, which can be used for different aperture depths. The number of flow stops is limited, and the three-way flow adjustment mechanism must still be retained). In this way, the amount of flush water in the borehole can be reduced, thereby reducing the wear and power consumption of the flushing fluid to the tee. Because it adopts the structure of four-speed shifting in the pump body, it has small size and weight and good decomposability. It is easy to carry in mountain, not only can discharge clean water, but also can discharge quite thick mud, so it is suitable for geological exploration.

Drilling Rig Mud Pump Technology

The mud weight ν is calculated according to the requirement of balanced formation pressure. That is, ν H = PC or ν H = P0. PC and P0 are the formation lateral pressure or formation pore fluid pressure at well depth h. see Section 3 of this chapter for their determination methods. So, whether it is calculated by PC or by P0 depends on which kind of pressure is more important to balance. If both of them need to be balanced, the two results should be calculated separately and a value between them should be balanced. Generally, the weight of drilling mud is between 1.02 and 1.40. 2. Considering the requirements of suspended drilling slag and wall protection to determine the rheological property of mud. The main indexes of rheological property are viscosity ε and shear force η. The adjustment range of ε and η is very wide. Generally, the range of ε is from 10cp to 100CP, and the range of η is from to, which should be determined according to different drilling conditions. In addition, in some cases, shear dilution and thixotropy of the slurry should be considered. The reference range of other design indexes of mud is as follows: the water loss shall not be greater than 15ml / 30min, the sand content shall not be greater than 8%, and the colloid rate shall not be less than 90%. The pH value varies from 6 to 11 depending on different muds, and the lubricity shall be controlled within when necessary.

With the increase of the pressure and displacement of the mud pump for geological exploration, the wear resistance requirements of the cylinder liner which is easy to wear are also increasing. In order to improve the wear resistance of mud pump liner, this paper uses the modern computer technology, based on the finite element analysis software ANSYS, carries on the finite element analysis to the mud pump liner, and finds the method to improve the wear resistance of the liner.
