Embodiment Construction

[0011] In the figure, two agitators 5 are arranged on the left and right sides of the mud pool 1; chemical additives are added to the mud pool 1, and two dispersion shafts 4 are arranged in the middle of the mud pool 1, and an impeller 2 is respectively arranged at the lower end of each dispersion shaft 4, and an impeller 2 is arranged at the upper end respectively. A drive wheel 9 is set; and a dispersing motor 8 is set above the middle part of the mud pool, and the dispersing motor 8 cooperates with the transmission of the two drive wheels 9 through the drive belt 7; The launch end 3 of 6 goes deep into the mud pool 1 bottom.

[0012] The transmitting end 3 of the ultrasonic generator and the two dispersing shafts 4 are arranged in a triangle; the two impellers 2 are arranged one above the other in a staggered manner.

[0013] When the equipment is working, two agitators 5 stir the mud, and the two dispersion shafts 4 and two impellers 2 rotate under the drive of the dispers...

Abstract

The invention relates to mud-modifying equipment with a physical method, which is matched with petroleum drilling for use. Two stirrers are arranged in the left and the right of a mud pit, and a chemical auxiliary is added into mud. Two dispersing shafts are arranged in the middle part of the mud pit, the lower end of each dispersing shaft is provided with an impeller, and the upper end of each dispersing shaft is provided with a driving wheel. A dispersing motor is arranged on the middle part of the mud pit and is in driving fit with the two driving wheels through driving belts. Meanwhile, an ultrasonic generator is arranged on the middle part of the mud pit, and the transmitting terminal of the ultrasonic generator penetrates into the bottom of the mud pit. When the equipment works, through ultrasonic waves and the rotary impellers on the two dispersing shafts, mud is subjected to cavitation vibration in solid phase and liquid phase interfaces, so that the mud liquid is dissolved and emulsified further, and the purpose that the mud performance is improved is achieved.

Description

Technical field [0001] The invention relates to a mud modification equipment used in conjunction with oil drilling, in particular to a physical method mud modification equipment using ultrasonic waves and a disperser. Background technique [0002] At present, the mud modification equipment used in oil drilling mainly improves the technical indicators such as the water loss rate of the mud by adding chemical additives to the mud, which has the defects of large chemical pollution, high cost and poor effect. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a physical mud modification equipment. The technical scheme that this invention solves its technical problem is: [0004] 1. A kind of physical method mud modification equipment. Two agitators are arranged on the left and right sides of the mud pool; chemical additives are added to the mud pool, and the characteristics are: two dispersion shafts are set in th...
