Abstract
The invention relates to a rope rotating type hydrate boring sampler, which comprises a catch head, a locking mechanism, a pull rod, a piston and a sample protecting cylinder which are connected through threads. The pull rod is fixed with a heat-insulation pressure-maintenance cylinder through a lockpin; a control system and a pressure compensation device are arranged in the heat-insulation pressure-maintenance cylinder; a hanger bearing, the heat-insulation pressure-maintenance cylinder, a ball valve body and a temperature pressure recorder are connected together; a core cutting mechanism is arranged in the sample protecting cylinder; the sample protecting cylinder and the piston are arranged in the heat-insulation pressure-maintenance cylinder; and a sampling drill bit and a shell are connected through threads. The whole device is arranged on the shell of the device through the locking mechanism; the shell is connected with a drilling tool to transmit torque and support weight of internal devices. When the device carries out sample boring operation, fluid fed by a pump on the ground flushes a borehole, and cleans the sampling drill bit; the shell rotates along with a drilling tool, while the heat-insulation pressure-maintenance cylinder and a sample protecting pipe do not rotate; the heat-insulation pressure-maintenance cylinder is retracted by a rope, so that time of the rock sample to the ground is shortened, thereby facilitating heat insulation and pressure maintenance of the rock sample.
Description
Technical field
The invention belongs to the special device of hydrate probe boring sampling, mainly be useful in the seafari technical field.
Background technology
The deep earth sampling device of present domestic utilization all is non-probing formula, and sampling depth only has 10 meters, mainly is the sediment sampling to sea-bottom shallow, the seabed hard formation is implemented boring with sampling also do not conduct a research; External some that use is the probing type, but complex structures all, the sampling effect is undesirable, and majority does not have the heat-insulation pressure keeping function, even there is the heat-insulation pressure keeping function not have the pressure and temp pen recorder, can not satisfy the needs of the sampling of deep sea hydrate exploration from now on yet.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of cable rotary type hydrate probe boring sampling apparatus, when carrying out deep-sea drilling, utilize this cable rotary type hydrate probe boring sampling apparatus can realization to obtain hydrate sample in the hard formation, be not subjected to the influence of the rock stratum depth, as long as need just to utilize drilling ship to take a sample,, utilize rope to trip out sampler when sampling finishes, do not need to trip out drilling tool, make rock sample reach ground from the shaft bottom fast and enter the laboratory.Purpose of the present invention just provides a kind of cable rotary type hydrate probe boring sampling apparatus.
For addressing the above problem, cable rotary type hydrate probe boring sampling apparatus of the present invention comprises dozen fishing head, locking mechanism, control system, pressure compensator, heat-insulation pressure keeping tube, temperature, pressure registering instrument, piston, pull bar, overcoat, chisel bit, ball valve body, cuts concentric mechanism, protects sample pipe and drop-hanger bearing.It is characterized in that fishing head, locking mechanism, pull bar, piston, guarantor's sample pipe are by being threaded, pull bar is fixed by lock pin and heat-insulation pressure keeping tube, control system, pressure compensator are arranged in the heat-insulation pressure keeping tube, drop-hanger bearing, heat-insulation pressure keeping tube, ball valve body, temperature, pressure registering instrument connect, cutting concentric mechanism is arranged in guarantor's sample pipe, protect the sample pipe, piston is arranged in the heat-insulation pressure keeping tube, chisel bit and overcoat are by being threaded.
When taking a sample operation, with in sampler input (or wire rope is sent into) the large scale drilling rod, sampler is sitting in outer putting from well head, and liquid and rotation drilling tool by the ground pumping make the chisel bit drive sampling.When sampling finishes, be lowered to the rope salvaging system from well head and dock, the pulling fishing head with fishing head, the locking mechanism automatic unlocking, pull bar pulling piston and guarantor's sample pipe are up, and pull bar and heat-insulation pressure keeping tube are thrown off, and protect the sample pipe in company with upstroke, when piston arrives heat-insulation pressure keeping tube upper end, protect the sample pipe and enter in the heat-insulation pressure keeping tube, be installed in the control system work in the heat-insulation pressure keeping tube, start ball valve body ball valve is closed, guarantor's sample pipe is in the sealed chamber, plays the effect of heat-insulation pressure keeping.The employing cable rotary type hydrate probe boring sampling apparatus can be implemented in the serial sampling in the hard formation, is not subjected to the restriction of the rock stratum depth.Sampling finishes to utilize to extract sampling device on the rope, and speed is fast, helps shortening the time of rock sample from the shaft bottom to ground, helps the heat-insulation pressure keeping of rock sample.This sampler not only has pressure compensation mechanism, and is provided with the temperature, pressure registering instrument in pressure-maintaining and heat-preservation tube bottom, reflects the temperature, pressure situation of rock sample in the seabed truly.Because the top at the heat-insulation pressure keeping tube of this device is provided with the drop-hanger bearing structure, when drilling tool drove the chisel bit rotation, heat-insulation pressure keeping tube and protect the sample tube and do not change relatively helped the raising of rock sample yield rate.

Embodiment
Now the invention will be further described in conjunction with Figure of description.
When adopting the present invention to carry out the deep earth sampling operation, with overcoat 9 with at the bottom of large scale drilling tool 15 is connected lower going-into-well.With fishing head 1, pull bar 8, locking mechanism 2, piston 7, protect sample pipe 13 by being threaded, fixing by locking mechanism 2 with overcoat 9, pull bar 8 is fixing by lock pin and heat-insulation pressure keeping tube 5, control system 3, pressure compensator 4 are arranged in the heat-insulation pressure keeping tube 5, heat-insulation pressure keeping tube 5, ball valve body 11, temperature, pressure registering instrument 6 connect, cut concentric mechanism 12 and be arranged on and protect in the sample tube 13, protect sample pipe 13, piston 7 is arranged in the heat-insulation pressure keeping tube 5, chisel bit 10 and overcoat 9 are by being threaded.
When taking a sample operation, with in sampler input (or wire rope is sent into) the large scale drilling tool 15, sampler is sitting on the overcoat 9 from well head, and liquid and rotation drilling tool by the ground pumping make chisel bit 10 drive samplings.When sampling finishes, being lowered to the rope salvaging system from well head docks with fishing head 1, pulling fishing head 1, locking mechanism 2 automatic unlockings, pull bar 8 pulling pistons 7 and guarantor's sample pipe 13 are up, pull bar 8 is thrown off with heat-insulation pressure keeping tube 5, it is up in company with piston 7 to protect sample pipe 13, when piston 7 arrives heat-insulation pressure keeping tube 5 upper ends, protect sample pipe 13 and enter in the heat-insulation pressure keeping tube 5, be installed in control system 3 work in the heat-insulation pressure keeping tube 5, start ball valve body 11 ball valve is closed, guarantor's sample pipe 13 is in the sealed chamber, plays the effect of heat-insulation pressure keeping.
