Background technology
In the coiled tubing operation, it is the important means that industrial gas oil down-hole band is pressed well workover and completion practice that coiled tubing bores the mill operation technique, 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 obstruction 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 material, 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, it does not have corresponding connector to realize being connected of strainer and quick demounting tool just can not realizing the fast quick-detach to the cartridge filter assembly yet.
Summary of the invention
For solving above-mentioned existing in prior technology technical problem, the utility model proposes a kind of coiled tubing drilling cuttings capturing device connector, the utility model principle is clear, be skillfully constructed, easy to operate, safe and reliable, can satisfy the requirement that the shutoff of coiled tubing drilling cuttings capturing device cartridge filter is connected with cartridge filter Fast Installation demounting tool.
The utility model is realized by adopting following technical proposals:
A kind of coiled tubing drilling cuttings capturing device connector, it is characterized in that: comprise the hammer ram terminal pad, cartridge filter plug and standpipe terminal pad, the side of hammer ram terminal pad is by being threaded onto an end inside of cartridge filter plug, cartridge filter plug hollow, the other end of cartridge filter plug is provided with the male joint that is connected for the cartridge filter box, cartridge filter plug body near the male joint end is provided with the packing groove, the cartridge filter plug is tightly connected by packing and standpipe, and the standpipe terminal pad is worn near an end of hammer ram terminal pad from the cartridge filter plug and is hung on the described cartridge filter plug.
Be disposed with a square packing groove and an O shape packing groove near on the cartridge filter plug body of male joint end, square packing groove is near the male joint direction.
Hammer ram terminal pad card center is provided with the box joint that links to each other with the quick demounting tool pin thread of cartridge filter.
One end of described standpipe terminal pad is provided with the box joint, links to each other with the male joint of standpipe.
Have two Fast Installation dismounting via holes that the core with the hammer ram terminal pad is centrosymmetric in the card of hammer ram terminal pad.
Be provided with two Fast Installation dismounting via holes in the side of standpipe terminal pad.
Compared with prior art, the beneficial effects of the utility model show:
1, in the utility model, coiled tubing drilling cuttings capturing device connector by hammer ram terminal pad, cartridge filter plug and the formation of standpipe terminal pad, principle is clear, be skillfully constructed, easy to operate, safe and reliable, can satisfy the requirement that the shutoff of coiled tubing drilling cuttings capturing device cartridge filter is connected with cartridge filter Fast Installation demounting tool.
2, in the utility model, be disposed with a square packing groove and an O shape packing groove near on the cartridge filter plug body of male joint end, square packing groove is near the male joint direction, and such form of structure makes the sealing performance between cartridge filter plug and the standpipe better.
