For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of automatic grouting circulating apparatus, comprise the tool joint, lengthening joint, mandrel, flexible pipe, mud valve and the guide cone that connect successively from top to bottom, on lengthening joint, be fixed with mooring staple, on mooring staple, be connected with theft-resistant link chain, the junction of mandrel and flexible pipe is arranged with jointing, and the mandrel outer wall that is positioned at jointing top is arranged with seal assembly.
Further, above-mentioned seal assembly comprises the sealing retaining ring, packing unit and the guide ring that are set in successively from top to bottom mandrel outer wall, and guide ring is provided with mud introducing port, and the material of packing unit is polyurethane.
Further, above-mentioned mud valve comprises valve seat, little spring, spool, piston and main spring, and main spring touches mutually with piston, and spool is movably fixed on valve seat, between valve seat and spool, is provided with little spring, is also equipped with multiple apertures on valve seat.
Further, the material of above-mentioned guide cone is copper, and its bottom surface is the conical surface.
Further, the outer cover of above-mentioned guide cone is provided with vulcanized rubber.
The utility model has the advantages that: this apparatus structure is reasonable, easy to operate, can in oil, Natural Gas Drilling Operation process, realize automatic grouting and cycle operation, simultaneously, mud valve can effectively avoid mud to be leaked to the situation of raised platform around a well face, and the employing of mooring staple and theft-resistant link chain makes the use of whole device more safe and reliable.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure for amplifying schematic diagram of a-quadrant in Fig. 1;
Fig. 3 is the structural representation of mud valve in the utility model.
Wherein, 1, tool joint, 2, lengthening joint, 3, theft-resistant link chain, 4, mooring staple, 5, mandrel, 6, seal assembly, 601, sealing retaining ring, 602, packing unit, 603, guide ring, 613, mud introducing port, 7, flexible pipe, 701, connect connector, 8, mud valve, 801, valve seat, 802, little spring, 803, spool, 804, piston, 805, main spring, 9, guide cone.
Detailed description of the invention:
As shown in Figure 1 to Figure 2, a kind of automatic grouting circulating apparatus, comprise the tool joint 1 connecting successively from top to bottom, lengthening joint 2, mandrel 5, flexible pipe 7, mud valve 8 and copper guide cone 9, on lengthening joint 2, be fixed with mooring staple 4, on mooring staple 4, be connected with theft-resistant link chain 3, mandrel 5 is arranged with jointing 701 with the junction of flexible pipe 7, mandrel 5 outer walls that are positioned at jointing 701 tops are arranged with seal assembly 6, seal assembly 6 is followed successively by sealing retaining ring 601 from top to bottom, packing unit 602 and guide ring 603, guide ring 603 is provided with mud introducing port 613, mud valve 8 comprises valve seat 801, little spring 802, spool 803, piston 804 and main spring 805, main spring 805 touches mutually with piston 804, spool 803 is movably fixed on valve seat 801, between valve seat 801 and spool 803, be provided with little spring 802, on valve seat 801, be also equipped with multiple apertures, the bottom surface of guide cone 9 is the conical surface.
When use, tool joint 1 is connected with the central tube of top-drive device, realizes the movement of this device by moving up and down of top-drive device, and guide cone 9 inserts in sleeve pipe and is in the milk.Wherein, one end of theft-resistant link chain 3 is connected with mooring staple 4, and its other end is connected with suspension ring, even in the time that tool joint 1 screw thread unclamps, this device also can not be fallen in well, makes the use of this device safer, and lengthening joint 2 has guaranteed that operator adopts the operation readiness in longer suspension ring situation; Sealing retaining ring 601 can prevent the axial float of packing unit 602 in device grouting operation process, packing unit 602 is polyurethane material, there is certain elasticity, the mud introducing port 613 that mud is passed through on guide ring 603 imports behind the inside of packing unit 602, packing unit 602 can be subject to compression swelling, its surrounding is close on the inwall of sleeve pipe to the sealing while having improved grouting operation; Flexible pipe 7 is a kind of high pressure resistant pipes, has both prevented any rigid collision between this device and sleeve pipe, again sleeve pipe is moved and carries out suitable bit shift compensation; The mud passing in mud valve 8, to piston 804 and spool 803 build-ups of pressure, makes the downward stretching little spring 802 of spool 803, and meanwhile, piston 804, to lower compression main spring 805, is realized grouting effect; Stop after grouting, piston 804 and spool 803 set back respectively under the effect of main spring 805 and little spring 802, the design of little spring 802 makes mud valve 8 can comparatively fast stop grouting, has more effectively avoided mud to be leaked to the generation of the situation of raised platform around a well face, has also improved grouting efficiency; The outside of guide cone 9 is also sheathed vulcanized rubber, protective casing is the injury to it in the time of this device play.
