Problems solved by technology

[0003] Since the drilling construction requires dozens of days or even several months of drilling operations, and geological logging requires cuttings samples to be taken every 1 to 2 meters, the shortest sampling interval is 1 to 2 minutes, and the weight of cuttings each time At about 500 grams, no matter day or night, windy or rainy or severe cold or hot summer, sampling must be strictly carried out 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, which will cause confusion to the analysis of geological cuttings and directly affect the results of geological interpretation and oil exploration and development.

Abstract

The invention relates to the technical field of geological logging for petroleum drilling, in particular to an automatic debris collection and washing machine, which comprises a collection groove. A first water inlet and a first outlet are formed in the collection groove respectively. The first water outlet is connected with a storage barrel. A storage barrel cover is arranged at the top of the storage barrel. An air hole is formed in the storage barrel cover, and is connected with a vacuum power device through an air pipe. A vaccumizing device for vacuumizing the storage barrel to generate a pressure difference with the outside is arranged in the vacuum power device. A second water outlet is connected with the first water inlet. A purification device is arranged between the second water outlet and the first water inlet. The automatic debris collection and washing machine is used for continuously collecting debris without manual debris collection, and is controlled by a computer, so that a collection period is accurately mastered, manual collection errors can be avoided, and the machine is conveniently and rapidly used.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling geological logging, in particular to an automatic cutting and washing machine for cuttings. 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 shale 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 summe...
