a dust collector

Abstract

The invention provides a dust collecting barrel which comprises a filter barrel arranged in a shell. The shell is a circular pipe with one end provided with an annular bottom plate, and a connecting pipe penetrates through the annular bottom plate. According to the dust collecting barrel, the dust collecting barrel is connected with a liquid outlet pipe through a standard union, so that an abrasive dust filtering and collecting device is standardized, the defect that an existing abrasive dust filtering and collecting device is disposable and can not be repeatedly used is overcome, the service life of the abrasive dust filtering and collecting device is prolonged, and popularization is worthy.

Description

technical field [0001] The invention relates to the technical field of oil and gas field reservoir reformation, in particular to a chip collecting drum, which is one of the important ground auxiliary tools in drilling and grinding operations of oil, gas and water wells. Background technique [0002] During drilling and grinding operations, it is necessary to collect and identify the returned grinding debris in real time, so as to control the drilling and grinding process according to the material, size and shape of the grinding debris. Sometimes it is even necessary to clean, dry and weigh the collected grinding debris in order to The drilling and grinding effect and chip-carrying efficiency are evaluated according to the total weight of the returned chips. Therefore, a filtering and collecting device is needed to collect the sieved grinding chips, and discharge the leached drilling and grinding working fluid and small-size impurities into the sewage pool or waste liquid rec...

Problems solved by technology

[0003] The wear debris collection device is one of the important ground auxiliary tools in the drilling and grinding operation of oil, gas and water wells. At present, most of the grinding debris collection devices used in the drilling and grinding operations of oil, gas and water wells are made by hand. The number of construction wells for abrasive composite bridge plugs is limited. In order to reduce costs, the construction party often uses iron screens to process them into a "fence" shape, and holds the handle to stand near the liquid outlet to pick up abrasive debris, or make it into a "fence". It is in the shape of a sieve, which is hung on the end of the liquid pipeline to filter and collect wear debris. There is no uniform style and size, which is contrary to the principle of "standardization" on the construction site, and has a limited service life. They are all disposable products and cannot be reused.
