Water-saving type petroleum geology logging and sand-washing device

Abstract

The invention discloses a water-saving type petroleum geology logging and sand-washing device, which comprises a base, a water tank, a sieve plate, a conveyor belt, a first cleaning tank, a second cleaning tank and a support. A feed hopper is arranged on the upper end of the support; the sieve plate is arranged on the lower end of the feed hopper; the water tank is arranged on the inner side of the support; a water holding tank is arranged on the upper end of the water tank; the conveyor belt is arranged on the right side of the sieve plate; the first cleaning tank is arranged on the right side of the conveyor belt; a rolling wheel is arranged in the first cleaning tank; the second cleaning tank is arranged on the right side of the first cleaning tank; a sliding rail is arranged on the bottom part of the second cleaning tank; a sliding block is slidably connected into the sliding rail; and the upper end of the sliding block is fixedly connected with a cleaning barrel. Through setting amulti-stage sand-washing process, a favorable sand washing effect is achieved, an automation degree is high, the manpower is reduced, meanwhile, the problem that real cuttings run away due to an improper manual sand-washing method is solved, a water resource is recycled so as to be saved, and the practicability is high.

Description

technical field [0001] The invention relates to a sand washing device, in particular to a water-saving sand washing device for petroleum geological mud logging. Background technique [0002] Sand washing equipment is equipment for washing ore, sand and gravel and other materials. 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 shale shaker. For a long time, rock cuttings have been collected manually at the construction site, and then the cuttings stained with drilling mud are washed with water, taken back to the geological room for drying, and then geological analysis. In order to ensure the accuracy of sampling, each geologic...

Problems solved by technology

For a long time, rock cuttings have been collected manually at the construction site, and then the cuttings stained with drilling mud are washed with water, taken back to the geological room for drying, and then geological analysis. In order to ensure the accuracy of sampling, each geological logging team A certain number of workers must be specially assigned to carry out sand sampling. The traditional method of repeatedly agitating and elutriating sand samples will cause the loss of real cuttings, which is not conducive to the development of on-site cuttings layering work. Some sand washing devices have poor sand washing effect. It also affects the development of cuttings layering work, and the process of washing with water in the sand washing process wastes a lot of water resources
