Embodiment Construction

[0027] The intelligent debris cleaning device is composed of a sleeve 1, an upper joint 2, a lower joint 3, a flow diversion assembly and a scraper 4. An upper joint 2 is installed on the internal thread of one end port of the sleeve 1, and the upper joint 2 is used to connect the upper pipe string , in order to transmit the rotational force of the drilling tool, the drilling fluid of the upper pipe string enters the cleaning device through the inner hole of the upper joint 2, and the inner thread of the other end port of the sleeve 1 is equipped with a lower joint 3, which is used to connect the lower joint. Downhole tool, in order to continue to transmit the rotating force downward, the drilling fluid in the cleaning device enters the downhole tool at the lower part through the inner hole of the lower joint 3; the inner holes of the sleeve 1, the upper joint 2 and the lower joint 3 are variable diameter holes, Wherein, the inner hole of the lower joint 3 is a trumpet hole wit...

Abstract

The invention relates to a removing device, in particular to an intelligent rock debris removing device. The intelligent rock debris removing device is composed of a sleeve, an upper connector, a lower connector, a flow distribution assembly and scraper blades; a port of one end of the sleeve is internally provided with the upper connector through a thread, and a port of the other end of the sleeve is internally provided with the lower connector through a thread; the position, between the lower connector and the upper connector, of the sleeve is movably sleeved with the flow distribution assembly through a thrust bearing; an installation flange is arranged in the sleeve and internally provided with installation cavities in a radial shape, and the installation cavities communicate with theflow distribution assembly; and the scraper blades are installed in the installation cavities, springs are arranged between the scraper blades and the sleeve, and the ends of the scraper blades extendto the outside of the sleeve. The intelligent rock debris removing device has the characteristics of being capable of removing only the bottom rock debris bed and good in removing effect, the problems that an existing removing device is unthorough in removing and poor in removing effect are solved, and the requirements of drilling engineering are met.

Description

technical field [0001] The invention relates to a cleaning device, in particular to an intelligent debris cleaning device. Background technique [0002] In the process of exploiting oil and gas resources, in order to adapt to the complex terrain structure and working conditions, people have developed a variety of drilling tools to realize the drilling function. If the cuttings are not cleaned in time, they will accumulate into a cuttings bed over time; the cuttings bed has a great safety hazard, which can easily hinder the movement of drilling tools, reduce the speed of drilling tools, and cause poor pumps, poor drills and stuck drills. Therefore, a cleaning device is required to remove bottomhole cuttings. [0003] Due to structural reasons, the traditional cleaning device can only scrape and clean the well wall at 360 degrees. Although it can clean the cuttings bed on the bottom well wall, the device scrapes the rock debris on the top well wall at the same time during the...
