Abstract

The invention relates to an automatic sand blasting device for an outer surface of a bushing. A sand box of the automatic sand blasting device for the outer surface of the bushing is connected with a sand blaster through a sand grain conveying pipeline; an air compressor is connected with the sand grain conveying pipeline through an air line; the sand blaster consists of a single-grain sand loading pipe, a sand grain nozzle and a sand blasting movable seat; the single-grain sand loading pipe is positioned outside the sand blasting movable seat; the sand grain nozzle is arranged in the sand blasting movable seat; the single-grain sand loading pipe is connected with the sand grain nozzle; the sand blasting movable seat is arranged on a sliding polished rod in a penetrating way; a transmission lead screw of a sand blasting feeding mechanism is in threaded connection with the sand blasting movable seat; the bushing is arranged on a rotary bracket; one end of the bushing is in threaded connection with an electric rotary disc of the rotary bracket, and the other end of the busing is arranged together with a bearing and a bearing fixing rod of the rotary bracket; and the sand blaster is arranged close to the bushing and can be used for blasting sand grains to the bushing. According to the automatic sand blasting device, automatic sand blasting of an oil field bushing is realized, the entire process is automatically realized, uniform sand blasting in an entire sand blasting process can be guaranteed, and the degree of standardization is high.

Description

1. Technical field: [0001] The invention relates to a device for enhancing the surface roughness of the casing designed to improve the bonding strength between the casing and the cement sheath in the oil and natural gas cementing process, and specifically relates to an automatic sandblasting device for the outer surface of the casing. 2. Background technology: [0002] In the technical field of oil field cementing process, for some formations, especially the layers with poor cementing effect, sticky sand casing (rubbing glue on the surface of the casing and sprinkling sand to improve the surface roughness of the casing) is often used for cementing to improve The bonding strength between the cement sheath and the casing surface improves the cementing quality of oil-water wells. At present, most of the viscose glue for oil field casing is manually operated by workers, that is, the glue is first manually brushed on the surface of the casing, and then sand particles of different...
