Abstract
The utility model relates to an accelerate the drilling mud liquid stream and invite, take the big a section of thick bamboo is salvaged in spiral components of a whole that can function independently of husky volume, including dipper, dabber and composite -joint, the composite -joint is connected with the dipper, and the dabber setting is equipped with spiral helicine mud guiding gutter in the dipper and the one end projection of dabber play dipper on the outer wall, such mud guiding gutter helps strengthening in the well velocity of flow of drilling mud liquid and takes husky volume with the reinforcing, makes the dipper sink that husky speed is faster, efficiency is higher.
Description
Technical field
The utility model relates to a kind of container for collection or deposited material in well or well, particularly relates to a kind of spiral split fishing socket.
Background technology
At present, for the treatment of the remaining fragment in down-hole, junk, as hard-metal insert, the relics such as bit bearing, adopt drags for husky instrument more, its for keeping that shaft bottom is clean, application life of improving drill bit, reduce and prevent down-hole contingency to have very important effect.But traditional drag for husky instrument and cannot bore mill, easily lock of tool drilling occurs, secondly, take in husky process at well-flushing, it is general lower that majority goes out husky well pressure coefficient, cannot set up circulation, cannot down-hole desilting be taken out of ground to such an extent as to desilting buries reservoir, cause production declining even to stop produce oil.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of spiral split fishing socket of new structure, make it have more value in industry.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind ofly to be accelerated drilling mud flow velocity, takes the large spiral split fishing socket of husky amount.
Spiral split fishing socket of the present utility model, comprise dipper, mandrel and composite-joint, described composite-joint is connected with dipper, and described mandrel is arranged in dipper and one end of mandrel stretches out dipper, and described dipper outer wall is provided with spiral helicine mud diversion trench.
Further, the external diameter of described dipper is 140-165mm, and the external diameter of described mandrel is 40-50mm.
Further, described dipper is distributed with spout hole.
Further, described spout hole is in spiral distribution on described dipper.
Further, described dipper offers mandrel locating hole.
Further, described composite-joint is connected by the first junction button with between dipper, described first junction button is set in composite-joint, and the described outer wall of the first junction button is connected with the inwall of dipper, described mandrel is connected by the second junction button with the first junction button, described second junction button is set on mandrel, and the inwall of described first junction button is connected with the outer wall of the second junction button.
By such scheme, the utility model at least has the following advantages: the utility model spiral split fishing socket drags for husky fishing socket dipper outer wall in routine has set up helical form mud diversion trench, its flow velocity contributing to strengthening drilling mud fluid in well takes husky amount to strengthen, and makes that dipper desilting speed is faster, efficiency is higher.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of manual, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model spiral split fishing socket.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See Fig. 1, a kind of spiral split fishing socket of the utility model one preferred embodiment, comprise dipper 1, mandrel 2 and composite-joint 3, composite-joint 3 is connected with dipper 1, mandrel 2 is arranged in dipper 1 and one end of mandrel 2 stretches out dipper 1, and dipper 1 outer wall is provided with spiral helicine mud diversion trench 11; Its flow velocity contributing to strengthening drilling mud fluid in well of such mud diversion trench 11 takes husky amount to strengthen, and improves and drags for husky efficiency and process, makes that dipper 1 desilting speed is faster, efficiency is higher.
The external diameter of the dipper 1 of the utility model spiral split fishing socket is 140-165mm, stack shell is long is 4000mm, the external diameter of mandrel 2 is 40-50mm, the spiral split fishing socket of above specification is compared with common fishing cup, dipper 1 external diameter is larger, dipper 1 stack shell is longer with the annular gap reduced between well, and mandrel 2 diameter at rim of a cup place is less, namely the annular gap between mandrel 2 and well is large, therefore, drilling mud fluid suddenly declines at rim of a cup place flow velocity, form whirlpool greatly to weaken to make the husky ability of taking of drilling mud fluid, thus to realize in the heavier people's cup that minces and to pull out with trip-out.
The dipper 1 of the utility model spiral split fishing socket is distributed with spout hole 12 and spout hole 12 in spiral distribution realize on dipper 1 drilling fluid flow out with quick washing landwaste, the drilling mud fluid of final formation to flow in dipper 1 with desilting by dipper 1 rim of a cup, dipper 1 is also provided with mandrel locating hole 13 be beneficial to mandrel 2 be positioned install.
The described composite-joint 3 of the utility model spiral split fishing socket is connected by the first junction button 4 with between dipper 1, described first junction button 4 is set in composite-joint 3, and the outer wall of described first junction button 4 is connected with the inwall of dipper 1, described mandrel 2 is connected by the second junction button 5 with the first junction button 4, described second junction button 5 is set on mandrel 2, and the inwall of described first junction button 4 is connected with the outer wall of the second junction button 5, such connected mode dipper 1, install between mandrel 2 and composite-joint 3 very convenient, and can independent assortment series connection use.
The utility model spiral split fishing socket be for Tarim Basin carbonate strata leakiness easily across, desilting is buried reservoir and is caused production declining even to stop produce oil, circulation cannot be set up, bottom hole falling article works actual conditions specialized designs such as dragging for, draw at the experiment effect through multiple producing well practical application: its with enter well drilling tool and be connected facility, can singly only use, also can many series connection, application risk is little, drag for husky efficiency high, reproduce and carry product successful, be applicable to straight well, inclined shaft, any well type such as horizontal well, desilting in well can better be rinsed salvages totally, recover oil well production.
Below be only preferred embodiment of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
