Intelligent rock debris filtering-washing machine

Abstract

The invention relates to the technical field of geological logging in petroleum drilling, and particularly relates to an intelligent rock debris filtering-washing machine. The machine comprises a water tank, wherein the water tank is connected with an acquisition device, a transmission device and a collection device; the acquisition device comprises a sand receiving device with a water inlet and a water outlet, and the water outlet is connected with a conduit which is oblique; the transmission device comprises a driving motor, a drive shaft of the driving motor is connected with a swing arm, and the end of the swing arm is provided with a sand filtering device opposite to the outlet of the conduit; the water tank also comprises an acquisition bin; the acquisition device is arranged in the acquisition bin and comprises a sand receiving funnel for receiving the sand filtered out of the sand filtering device; a rotating plate is arranged below the sand receiving funnel, and a plurality of first filter cartridges are arranged on the rotating plate. With mechanical processing instead of manual work, the intelligent rock debris filtering-washing machine has strong adaptability; besides, the accuracy of mechanical processing is high and acquisition errors are avoided.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling geological logging, in particular to an intelligent cuttings washing machine. Background technique [0002] During the oil drilling process, the high-speed flowing mud in the drilling tool carries the drilling cuttings downhole to the surface, and then the cuttings are filtered out through the mud shaker. For a long time, rock cuttings have been collected manually at the construction site, and then the rock cuttings with drilling mud adhered to the surface are washed with water and brought back to the geological room for geological analysis. [0003] Since the drilling operation needs to be carried out for dozens of days or even several months, and in geological logging, it is required to take a cuttings sample every 1 to 2 meters, and the minimum sampling interval is 1 to 2 minutes. At about 500 grams, no matter day or night, windy or rainy, or severe cold or hot summer, sampling must...

Problems solved by technology

[0003] Since the drilling operation needs to be carried out for dozens of days or even several months, and in geological logging, it is required to take a cuttings sample every 1 to 2 meters, and the minimum sampling interval is 1 to 2 minutes. At about 500 grams, no matter day or night, windy or rainy, or severe cold or hot summer, sampling must be carried out strictly according to the construction progress. The workload is heavy and the working environment is very harsh. Moreover, it is easy to make mistakes when collecting rocks manually. The analysis of cuttings causes confusion, which directly affects the geological interpretation and the effect of oil exploration and development
