A kind of conveying roller compaction device for drilling

Abstract

The invention discloses a conveying and rolling device for drilling, which includes a fixed casing, a planetary gear set, an inner shaft, a drill bit connecting cylinder, an impeller, a grinding disc and a rolling wheel mechanism, wherein the planetary gear set includes a ring gear, a center Sun gear, planetary carrier and multiple planetary gears; the inner shaft is driven to rotate by the central sun gear; the drill bit connecting cylinder is located below the planetary carrier and vertically arranged, and the rolling wheel mechanism is fixedly connected to On the planet carrier, the drill bit connecting cylinder is fixedly connected to the rolling wheel mechanism; the impeller is located below the grinding disc, which can transport materials upward when rotating; the grinding disc is provided with an annular grinding groove And material ascending chute; said rolling wheel mechanism includes grinding wheel and material ascending channel. The invention can realize that the material gradually rises from the hollow cylinder and is conveyed out after rolling and crushing, with reliable operation and low energy consumption.

Description

technical field [0001] The invention belongs to the field of drilling equipment, and more specifically relates to a conveying and rolling device for drilling. Background technique [0002] With the economic development, the number of oil and gas drilling is increasing rapidly, which also drives the need to change the drilling method. Traditional drilling equipment includes drilling rigs, derricks, hoisting systems and turntables, which require a huge system, and the drilling efficiency is low, and the holes drilled during the drilling process are relatively large, resulting in waste of energy. In addition, it needs to use the water circulation of the water circulation to discharge the drill cuttings for chip removal. [0003] The current ultra-slim hole drilling method using the rig-free drilling technology does not require a drilling rig, a derrick, a lifting system and a rotary table, and the drilled hole is an ultra-slim hole, which greatly improves drilling efficiency a...

AI Technical Summary

Problems solved by technology

Since there is no drilling rig and derrick in the rig-free drilling technology at this stage, the traditional way of water circulation to discharge cuttings is inseparable from the drilling rig and derrick, and whether it is transporting dry cuttings or water-containing cuttings, it is necessary to inject a large amount of water into the bottom of the well and then drain the water. It is pumped out together with the mixture of cuttings, which will cause a great waste of energy
