Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] figure 1 , figure 2 It shows a mud tank for drilling, the main body of the tank body is in the shape of a cuboid tank, including tank side plates and a tank bottom plate 11, a bottom plate support structure is arranged below the tank body bottom plate 11, and the bottom plate support structure It is composed of a bottom transverse rib plate 8 and a bottom longitudinal rib plate 9. The tank side plate is divided into an upper tank side plate 1 and a lower tank side plate 2. The upper tank side plate 1 is vertical Side plate, the short side of the lower tank body side plate 2 is a vertical side plate, and the long side is a quarter arc plate bent inward; the tank at the upper opening of the tank body The outer periphery of the body side plate is fixedly provided with a rib plate 4 on the side plate, and the rib plate 5 in the side plate is fixed...

Abstract

The invention discloses a mud tank for well drilling. A main body is of a cuboid tank shape and comprises a tank body side plate and a tank body bottom plate, a bottom plate supporting structure is arranged below the tank body bottom plate, the tank body side plate is divided into an upper tank body side plate portion and a lower tank body side plate portion, each short side of the lower tank body side plate portion is a vertical side plate, and each long side of the lower tank body side plate portion is a one-quarter arc plate bent inwards. An upper side plate reinforcing rib plate is fixedly arranged on the periphery of the position, at an upper opening of the tank body, of the tank body side plate, and a middle side plate reinforcing rib plate is fixedly arranged on the periphery of the position, at the joint of the upper tank body side plate portion and the lower tank body side plate portion, of the tank body side plate. The mud tank for well drilling is superior and more reasonable in structure, can meet strength requirements, can also be used for completing mud stirring more uniformly and thoroughly, and reduces the production and use cost.

Description

technical field [0001] The invention relates to a drilling equipment, in particular to a drilling mud system equipment. Background technique [0002] The mud system is a key part of the oil drilling process, and the mud tank is an important equipment in the mud system. Its main purpose is to hold mud. Slurry is characterized by a high specific gravity (1.4 to 2.5, compared to 1.0 for water), high viscosity, and complex chemical composition. [0003] In traditional mud tanks, corrugated plates are often used as the side walls of the tank to increase the rigidity of the tank against the lateral hydrostatic pressure of the liquid. In terms of structural strength, traditional mud tanks first need a strong enough stress-bearing frame, and then the side walls and bottom of the tank are used as plate structures to withstand the bending moment generated by the hydrostatic pressure of the liquid on the surface. Since the plate structure is not good at bearing bending, if the bendi...
