Description
Technical field
The utility model relates to petroleum geology exploration, lithologic analysis, geological prospecting aid, coring tool applied technical field, the automatic corer of especially a kind of totally-enclosed stealthy pawl.
Background technology
Before enforcement Oil/gas Well creeps into, develops reservoir, in order to meet target spot acquisition parameter to drill bit, first to understand the rock properties such as the anisotropy of this block formation drillability and rock; In order to understand the distribution of down-hole formation petroleum resources, reserves situation, better design oil and gas development scheme, needs to drill through construction to the rock core of different layers position, underground equally.Visible, rational geological prospecting scheme and accurately down-hole rock sample nature parameters are to the importance of oil-gas mining.
In order to obtain down-hole geologic information accurately, custom-designed coring tool is essential.At present, China's geological drilling coring tool structure is simple, and practicality is poor, is difficult to meet that soft or hard replaces stratum gets core requirement.
Prior art shortcoming
There is obvious generation-difference in the existing coring tool used for geological prospecting of China and international advanced technology, is mainly manifested in:
1. ground adaptability is poor, is difficult to meet soft or hard and replaces stratum and get core requirement.Be described as follows: the existing geological prospecting coring tool of China, different by getting core pawl structure, be mainly divided into two kinds, be respectively core gripper with slip-collar corer and formula core grabber corer of tackling all problems at once.Core gripper with slip-collar is adapted to hard formation and gets core, when rock core not Cheng Zhu, become post loose and intensity is not high or rock core attenuates time cannot capture down-hole rock core.The formula core grabber of tackling all problems at once is applicable to soft formation and gets core, and when when chance hard formation, rock core intensity is high, one-tenth rod structure is fine and close, core grabber can not draw in, cannot complete equally and get core task.
2. existing tool construction is single, and inner tube does not have radial restriction to rock core, easily causes rock core landing, and coring was lost efficacy.
3. outer tube structure design is unreasonable, gets in core process, easily carries out length travel with core grabber, cause core grabber work structuring to lose efficacy.
Utility model content
Prior art is difficult to the productive life needs meeting people, and in order to solve deficiency of the prior art, the utility model is intended to the automatic corer of a kind of totally-enclosed stealthy pawl of design.
For realizing this technical purpose, the technical solution adopted in the utility model is: the automatic corer of a kind of totally-enclosed stealthy pawl, comprise core bit, core bit bushing pipe, interior rock core casing shoe, clam box shell, core spring pawl, totally enclosed type flapper valve, clam box snap ring, cam ring, Compress Spring, interior pipe clamp ring, inner tube joint, interior rock core sleeve pipe, slotted countersunk flat head screw, O-ring seals, slips sliding block, interior pipe clamp watt sliding bar, galianconism bar, pipe clamp watt in self adaptation, long-armed bar, slips top shoe, interior pipe clamp watt pushes away spring, outer tube joint, rock core and automatic corer Assembly rail again, described core bit bushing pipe is at core bit, between interior rock core casing shoe and clam box shell, described clam box shell one end is inserted between core bit bushing pipe and interior rock core casing shoe, and another end is inserted between inner tube joint and outer tube joint, described core spring pawl is arranged on interior rock core sleeve pipe, and described core spring pawl is between core bit bushing pipe and clam box shell protruding part, described totally enclosed type flapper valve is between clam box shell and cam ring, Compress Spring is provided with between described cam ring and interior pipe clamp ring, described inner tube joint connects with interior rock core sleeve pipe with cam ring, described interior pipe clamp ring is connected by slotted countersunk flat head screw with inner tube joint, described slips sliding block is arranged on interior rock core sleeve pipe internal recessing side, described rock core is arranged in the middle of device.
Further, described interior pipe clamp watt sliding bar is inserted in interior rock core sleeve pipe through slips sliding block; Described interior pipe clamp watt sliding bar is provided with slips top shoe, is provided with interior pipe clamp watt and pushes away spring between described slips top shoe and interior rock core sleeve pipe, interior pipe clamp watt pushes away spring and is set on interior pipe clamp watt sliding bar; Described long-armed bar connects pipe clamp watt in slips top shoe and self adaptation; Described galianconism bar connects pipe clamp watt in slips sliding block and self adaptation.
Further, O-ring seals is provided with between described inner tube joint and interior rock core sleeve pipe.
Compared with prior art, the utility model has following beneficial effect: the automatic corer of this totally-enclosed stealthy pawl, and totally-enclosed clam case assembly is being got in core process, automatically closes clam box, namely by forcing totally-enclosed flapper valve inwardly to overturn centered by fulcrum, and completely closed in AnchorPoint.Create a closed storehouse with this, avoid the coring failure conditions caused because rock sample is loose.
Shell limit assembly, by the core spring pawl of wedging bottom rock core, limits the length travel of interior rock core casing shoe; Then by the length travel of clam box snap ring restriction outer tube assembly.Its meaning is, inner tube extracts in core process, and the length travel carried out followed by the irrelevant assembly of restriction.
