Including the drill bit body, set up the water hole on the drill bit body, extend from the drill bit body or fix a plurality of wing on the drill bit body, be provided with fixed cutting element on the wing, its characterized in that: the drill bit also comprises at least one nozzle, the nozzle comprises a mixed fluid, and a mixed fluid cavity, an exit port, a central hole communicated with the mixed fluid cavity and at least one cut-in groove communicated with the mixed fluid cavity are formed in the mixed fluid; the central hole is used for forming liquid direct current in the mixed flow cavity, and the cut-in groove is used for forming liquid rotational flow in the mixed flow cavity; the exit port is used for forming a channel for ejecting liquid in the mixing cavity. The invention aims to provide a diamond drill bit suitable for comprehensive drilling, which effectively solves the problems of short service life and reduced drilling capability of the existing drill bit caused by unreasonable hydraulic structure in the rock breaking process.

摘要：【中文】本发明公开了一种切入式直旋混合射流自进式喷嘴，属于油田采油工程技术领域。包括混流体，混流体上形成混流腔、与混流腔相通的中心孔、至少两个与混流腔相通的切入槽；中心孔用于在混流腔中形成液体直流，切入槽用于在混流腔中形成液体旋流，两股射流在混流腔内形成直旋混合射流。本发明的目的在于提出一种切入式直旋混合射流自进式喷嘴，能够以可靠的结构、直旋混合的射流方式破岩，在延长喷嘴工作寿命的同时，提高破岩效率。 【EN】The invention discloses a cut-in type direct-rotation mixed jet flow self-advancing nozzle, and belongs to the technical field of oil field oil extraction engineering. The mixing device comprises a mixing fluid, wherein a mixing cavity, a central hole communicated with the mixing cavity and at least two cut-in grooves communicated with the mixing cavity are formed in the mixing fluid; the central hole is used for forming liquid direct current in the mixed flow cavity, the cut-in groove is used for forming liquid rotational flow in the mixed flow cavity, and the two jet flows form direct-rotation mixed jet flow in the mixed flow cavity. The invention aims to provide a cut-in type direct-rotation mixed jet flow self-advancing nozzle which can break rock in a reliable structure and a direct-rotation mixed jet flow mode, and improve the rock breaking efficiency while prolonging the service life of the nozzle.
