Description
Technical field
The utility model relates to industrial gas oil down-hole technical field of construction, exactly relates to coiled tubing and bores the quick extracting tool that the mill construction operation is used coiled tubing drilling cuttings capturing device.
Background technology
Coiled tubing bores the important means that the mill operation technique is the band pressure well workover of industrial gas oil down-hole and completion practice in the coiled tubing operation, is the new technology that integrates coiled tubing equipment, positive displacement motor helicoid hydraulic motor, milling tool, ground infusion and return the discharge opeing filtering technique.It utilizes coiled tubing to transmit positive displacement motor and milling tool, utilize coiled tubing equipment real time data monitoring system to obtain crucial construction datas such as infusion pressure, infusion discharge capacity, well head pressure, the pressure of the drill, brill mill drilling depth, implement realtime construction project setting, construction commander and optimization operation, utilize the ground pumping-in equipment to implement to bore the mill operation by coiled tubing and positive displacement motor helicoid hydraulic motor for milling tool provides power, utilize the ground filter to filter the brill mill and return discharge opeing, capture drilling cuttings.Because coiled tubing bores mill by boring composite plastic, rubber, down-hole composite tool and fish such as compound bridging plug that cast iron constitutes, and down-hole tamper such as mud sediment, greatly a large amount of and super large drilling cuttings can return and drain into well head obstruction four-way junction of casing and choke manifold, cause brill mill working solution and down-hole liquid timely and effectively not to discharge, cause the leakage fluid dram lifting rate to reduce and even stop, well head, coiled tubing and positive displacement motor operating pressure raise, and then make coiled tubing bore the termination of mill construction operation, the well control security risk strengthens, therefore bore mill working solution and down-hole liquid return drain into four-way junction of casing after, entering must be through the ground filter before the choke manifold.Existing ground filter---desander, be primarily aimed at granule solid phase rule profile substance trapping designs such as reservoir sand, fracturing sand, only be suitable for capturing the granule drilling cuttings, because drilling cuttings sizes such as composite, mud sediment are big and out-of-shape, under high pressure, high flow rate effect, the drilling cuttings compacting is tight, and cleaning is difficulty quite.In addition, because the desander volume is little, the capture of incompatible a large amount of drilling cuttings, and desander complex structure, big, the Heavy Weight of volume, cost height, mobile difficulty, desander can not satisfy the construction operation needs in the mill operation so coiled tubing bores, and must use special coiled tubing drilling cuttings capturing device to filter the brill mill and return discharge opeing, captures drilling cuttings.
And the cartridge filter of existing coiled tubing drilling cuttings capturing device, its not corresponding extracting tool is fast finished the fast quick-detach to cartridge filter.
Summary of the invention
For solving above-mentioned existing in prior technology technical problem, the utility model proposes the quick extracting tool of a kind of coiled tubing drilling cuttings capturing device, the utility model principle is clear, be skillfully constructed, safe and convenient, time saving and energy saving, efficient is high, can satisfy the requirement of the fast quick-detach of coiled tubing drilling cuttings capturing device cartridge filter.Can be widely used in device under all kinds and the condition and the fast quick-detach of assembly.
The utility model is realized by adopting following technical proposals:
The quick extracting tool of a kind of coiled tubing drilling cuttings capturing device, it is characterized in that: comprise handle, center connecting rod and impact hammer, described handle is fixed on an end of center connecting rod, the other end of center connecting rod is pin thread, described impact hammer is provided with the through hole that runs through, the center connecting rod is socketed on the described through hole, and the external diameter of described handle is greater than the external diameter of described center connecting rod, and the external diameter of described impact hammer is greater than the external diameter of described handle.
Described handle and center connecting rod are integrally formed.
The dumbbell shape that is shaped as hollow of described impact hammer.
Be provided with the friction screw thread at the middle part of described impact hammer.
Compared with prior art, the beneficial effects of the utility model show:
1, in the utility model, the extracting tool that the mode of employing handle, center connecting rod and impact hammer forms, pin thread is connected with the connector of coiled tubing drilling cuttings capturing device, by the front and back bump of impact hammer to connector and handle, just can realize the purpose of fast quick-detach coiled tubing drilling cuttings capturing device cartridge filter, principle is clear, be skillfully constructed, safe and convenient, time saving and energy saving, efficient is high, can satisfy the requirement of the fast quick-detach of coiled tubing drilling cuttings capturing device cartridge filter.Can be widely used in device under all kinds and the condition and the fast quick-detach of assembly.
2, in the utility model, handle and center connecting rod are integrally formed, like this, even prolonged use also is difficult for making handle bad by center connecting rod bump, have prolonged service life.
3, in the utility model, the dumbbell shape that is shaped as hollow of impact hammer, such version has increased impact area and the processing safety of impact hammer to handle and connector, and mid portion is convenient to hold, and implements bump and move operation.
4, in the utility model, be provided with the friction screw thread at the middle part of impact hammer, when clashing into holds, can increase the frictional force of holding impact hammer.
Description of drawings
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments, wherein:
