Abstract

The invention discloses a near bit supporting device. The near bit supporting device comprises triangular brackets and a connecting mechanism; each triangular bracket comprises a supporting rod, and supporting legs fixed on the supporting leg; a supporting platform for supporting a near bit is arranged at the upper end of each supporting rod, and while the lower end of each supporting rod is connected with the connecting mechanism; the plurality of triangular brackets are connected and fixed through the same connecting mechanism. According to the near bit supporting device, the connecting mechanism is arranged between two supporting bodies, so that the supporting device can be avoided moving left and right; end plates are arranged on the supporting bodies to prop the near bit to avoid slipping during mounting; arc-shaped concave parts are arranged on the upper surfaces of the end plates, and therefore, the mounting stability is further improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a support device near a drill bit. Background technique [0002] In the directional drilling construction of oil, natural gas and coalbed methane, etc., the drilling trajectory is required to be drilled exactly according to the designed trajectory. Therefore, how to obtain accurate directional measurement data near the drill bit is the key factor for the success of directional well construction. With the development of current drilling technologies such as horizontal wells and branch wells, drilling operations need to obtain real-time information on formations and drilling tool positions in a timely manner, which has led to the rapid development of near-bit support and measurement, which can determine in real time Wellbore silicon base and formation lithology, so that the target hit situation can be determined in real time. [0003] The near-bit tool measures resistivity and natural gamm...
