Description
Technical field
The utility model belongs to oil/gas well underground work technical field, in particular to a kind of horizontal well coiled tubing is pressurized certainly
Cyclone sand washing device.
Background technique
As oil-gas field development enters the middle and later periods, the cementing tissue of sandstone is destroyed, and formation sand production is serious.Due to level
The particularity of well casing programme, horizontal segment is longer, the variation of pit shaft axis is irregular, and reservoir sand is easier to flow into pit shaft, and settles
It is formed by curing sand setting bed, seriously affects the normal production of oil/gas well, hydraulic sand washing operation need to be generally used, sand setting is carried to ground
Face.
Traditional sand washing technology uses 2-7/8 " oil pipe, and end installs sand-washing pen point and forms sand-flushing pipe column.The technology is easily led
The fluid only import but no export for entering pit shaft is caused, the normal circulatory system is not established, can not be successfully the sand washing operation for carrying out oil well.And
And the sand washing mode uses high flow rate operation, a large amount of sand cleaning fluid can be leak into stratum together with sand grains, causes hole stifled
Plug, oil reservoir contamination from water encroachment.Furthermore it carries out needing termination of pumping connected pipes when sand washing, it cannot be guaranteed that the continuity of work progress, if
It deals with the redeposition that can aggravate sand grains instead improperly, sand-flushing pipe column sand card accident can occur when serious, oil well is caused to turn overhaul very
It is scrapped to oil well.
Coiled tubing sand washing operation forms compound sand-flushing pipe column using coiled tubing tail band rotation sand flushing tool, by sand washing
Direct projection flow nozzle injection sand cleaning fluid on tool impacts casting bed.Compared with traditional sand washing technology, coiled tubing construction process
In without connecting tubing string, easy to operate, operating efficiency is higher.Also, it is not necessarily to termination of pumping during sand washing operation, can guarantee sand washing
Liquid constant impingement casting bed and taking in the wellbore returns on sand, prevents sand grains from falling after rise, avoids sand card tubing string.However, by coiled tubing
The limitation of itself, inner flow passage latus rectum is smaller, so that flow resistance is larger in sand cleaning fluid flow process, causes cyclic pressure dissipation larger,
The nozzle hydraulic energy obtained rotated on sand flushing tool is smaller, and sand cleaning fluid jet stream is in the cured sand setting bed of impact-level well
Effect is poor.If increasing the hydraulic energy of nozzle by the mode for increasing pump pressure, then it will lead to surface line and valve thorn leakage,
Bring security risk.Also, sand flushing tool is rotated in well when high pressure, the high environment high speed rotation containing sand, to the close of tool
Sealing property proposes larger challenge, and seal member is easy to cause to wear and seal failure, influences the progress of construction, reduces sand washing
Success rate.
