Movable well logging sand washing device

Abstract

The invention discloses a movable well logging sand washing device and relates to the technical field of oil field well logging equipment. The movable well logging sand washing device comprises a movable base, a sand cleaning pond located on the movable base, and a sand containing barrel located in the sand cleaning pond; the sand cleaning pond is provided with a cover plate which is provided with a water inlet in an excavating manner; the water inlet is communicated with an annular water spraying pipe located in the sand cleaning pond, and the inner diameter of the annular water spraying pipe is larger than the outer diameter of the sand containing barrel; the lower end of the pond wall of the sand cleaning pond is provided with a water outlet; the cover plate is provided with a rotating driving assembly and a lifting driving assembly driving the rotating driving assembly to move up and down; and the output end of the rotating driving assembly penetrates the cover plate, extends into the sand cleaning pond, and penetrates the top of the sand containing barrel to be fixedly connected with the top and the bottom of the sand containing barrel. According to the movable well logging sand washing device, the two driving assemblies are used for driving the sand containing barrel to rotate up and down in the sand cleaning pond containing clean water, rock debris and a mud mixture in the sand containing barrel are made to be separated to achieve the sand washing purpose, and the sand washing effect is ideal.

Description

technical field [0001] The invention relates to the technical field of oilfield mud logging equipment, and more specifically relates to a movable mud logging and sand washing device. 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 ...

Problems solved by technology

[0005] The object of the present invention is: in order to solve the problem that the sand washing effect of the existing mud logging and sand washing device is not ideal and cannot accurately reflect the stratification of cuttings, the present invention provides a movable mud logging and sand washing device, which is driven by two groups The component drives the sand tank to rotate up and down in the sand cleaning tank filled with clear water, so that the debris in the sand tank is separated from the mud mixture to achieve the purpose of sand washing, and the sand washing effect is ideal.
