Abstract

The invention provides a rock debris conveying device. The rock debris conveying device comprises a body with an axial cavity, a rotary part which is arranged in the axial cavity in a penetrating modeand is capable of rotating in the axial cavity, wherein the inner wall of the axial cavity is provided with a spiral groove; a spiral protrusion which can be embedded in the spiral groove is arrangedon the outer wall of the rotary part; the upper end face of the spiral protrusion is a plane; the lower end face of the spiral protrusion is a cambered face in smooth transition, and thus the lower end face of the spiral protrusion is attached to the inner wall of the spiral groove; and a gap allowing rock debris to pass through is formed between the upper end face of the spiral protrusion and the inner wall of the spiral groove. The rock debris conveying device can well convey rock debris out of a borehole.

Description

technical field [0001] The present application relates to the field of cuttings conveying, in particular to a cuttings conveying device. Background technique [0002] The descriptions in this section merely provide background information related to the disclosure in this application and may not constitute prior art. [0003] When drilling for oil, drilling mud is usually used to carry cuttings out of the wellbore. When there is no circulating mud and the water content of cuttings is uncertain, the effective transportation of cuttings becomes very difficult. The cuttings will enter the gap between the screw rod and the shell when the traditional screw is used to convey the cuttings, causing the screw rod to be stuck. [0004] It should be noted that the above introduction to the technical background is only for the convenience of a clear and complete description of the technical solution of the present application, and for the convenience of understanding by those skilled i...
