Embodiment 1

[0023] Such as figure 1 with figure 2 As shown, the present embodiment provides a vertical sand washing device for mud logging, including a base 5, a sand washing tank 4 arranged on the base 5, and a sand washing box 7 located in the sand washing tank 4. The opening of the sand tank 4 is detachably connected with a high-foot mounting plate 2, and the high-foot mounting plate 2 is provided with a lifting drive assembly 1. The output end of the lifting drive assembly 1 passes through the high-foot mounting plate 2 and extends to the sand washing tank 4. It is fixedly connected with the sand washing box 7. In this embodiment, the lifting drive assembly 1 drives the sand washing box 7 to reciprocate and vibrate up and down in the sand washing tank 4 filled with clean water, so that the clean water can wash away the rock debris and mud mixture in the sand washing box 7, In this way, the rock cuttings and the mud mixture are separated to achieve the purpose of sand washing, and th...

Embodiment 2

[0025] This embodiment is further optimized on the basis of Embodiment 1, specifically: the high foot mounting plate 2 includes two pairs of support foot assemblies 2-2 symmetrically arranged at the opening of the sand washing tank 4 and two pairs of support foot assemblies connected The mounting plate 2-1 of 2-2, the supporting foot assembly 2-2 includes the outer supporting foot 2-2.2 and the inner supporting foot 2-2.1 symmetrically arranged on the wall of the sand washing tank 4, and the outer supporting foot 2-2.2 and the inner supporting foot Between 2-2.1, an accommodation chamber matching the wall of the sand washing tank 4 is formed, and the outer leg 2-2.2 and the inner leg 2-2.1 are connected to the outer side wall and the inner side wall of the sand washing tank 4 through bolts respectively. Fixedly connected, the opening of the sand washing tank 4 is provided with a water inlet pipe 3 and a water outlet extending into the drain pipe 9 at the bottom of the sand wash...

Embodiment 3

[0027] This embodiment is further optimized on the basis of Embodiment 2, specifically: the upper end of the sand washing box 7 is open, and the opening is provided with an internal thread 7-1.1, the lifting drive assembly 1 is a cylinder, and the cylinder piston rod is connected There is a cover plate 8, the bottom of the cover plate 8 is fixedly provided with a connecting cover 8-1, and the inner wall of the connecting cover 8-1 is provided with an external thread 8-1.1 that cooperates with the internal thread 7-1.1, which can facilitate the work through threaded connection Personnel feed and take out materials, which improves work efficiency.

[0028] Based on the above embodiments, the part of the mounting plate 2-1 in contact with the cylinder piston rod is provided with a lubricating ring 10, which can reduce the sliding friction between the mounting plate 2-1 and the cylinder piston rod, ensuring that the cylinder piston normal operation of the rod.

[0029] Based on t...

Abstract

The invention discloses a vertical sand-washing device for logging and relates to the technical field of oilfield logging equipment. The vertical sand-washing device for logging comprises a base, a sand-washing pool arranged on the base and a sand-washing tank located in the sand-washing pool; a high mounting plate is detachably connected to an opening of the sand-washing pool and provided with alifting drive assembly; and the output end of the lifting drive assembly penetrates through the high mounting plate to extend into the sand-washing pool and is fixedly connected with the sand-washingtank. The sand-washing tank is driven by the lifting drive assembly to vibrate up and down in the sand-washing pool with clean water in a reciprocating mode, then rock debriss and a slurry mixture inthe sand-washing tank are separated so that the purpose of sand washing can be achieved, and the sand washing effect is ideal.

Description

technical field [0001] The invention relates to the technical field of oilfield mud logging equipment, in particular to a vertical sand washing device for mud logging. Background technique [0002] With the continuous development of the social economy and the continuous improvement of industrial production levels, the demand for oil in all walks of life is increasing. However, when obtaining oil, it is necessary to carry out drilling operations on the oil field. The high-speed flowing mud carries the drilling cuttings downhole to the surface, and then the cuttings are filtered out through the vibrating screen, and certain problems often arise in this operation. [0003] Usually, each drilling rig is equipped with two vibrating screens, and there is a certain distance between the vibrating screens, which are often used alternately in practical applications. However, for a long time, rock cuttings have been collected manually at the construction site, and then the rock cuttin...
