In water injection well in oil fields drifting technical field of tools.
Background technique
In oil exploitation production, in order to addedly descend reservoir energy, oil recovery factor is improved, water filling work is generallyd use
Skill.Due to containing a variety of chemical ions, impurity and microorganism in water filling, water injection well is after the long period of being on active service, the easy shape of shaft in wall
At scale, stick object, reduce caliber, water flooding well pipe damage is caused to increase, injection rate is reduced, and energy consumption increases.Timing is surveyed, hair is easy
The problems such as raw measurement and adjustment instrument device and tool string are hampered by card during going into the well.Going on smoothly for work is adjusted to guarantee to survey, is adjusted surveying
Before work is carried out, need to carry out scale removal drifting operation, to guarantee that wellbore environment is good.
Traditional descalling technique has chemical cleaning, high-pressure hydraulic scale removal, sound wave scale removal and mechanical descaling etc., and wherein chemistry removes
Dirt pipeline easy to damage in the construction process, pollutes environment and the time is long, at high cost；The installed capacity that high-pressure hydraulic scale removal needs
Greatly, the problems such as water consumption is more, and there are water process；And sound wave scale removal is only applicable to dirt loosely, to fine and close hard dirt
It does not prove effective.Therefore most commonly used is that drifting snaking operation is realized using mechanical gauguste cutter.
Mechanical gauguste cutter, in oily intraductal operation, relies primarily on own wt by wirerope connection weighted lever, gauguste cutter etc.
And snaking drifting operation is realized in percussion, cooperation steel wire operation frequent progress put-on and delegated.Fuel-displaced tubing string has not been needed, it is right
Although the dirt dirt inside oil pipe can play certain scavenging effect, scaling effect is poor, low efficiency.Due to be by counterweight and
The downward impact force of gauguste cutter realizes snaking operation, has much relations with tip shapes, weighted lever weight, any one link
Final scaling effect will be influenced, and the flow channels being easy to cause in oil pipe under percussion are blocked completely, because
This traditional mechanical gauguste cutter has been unable to meet the actual demand of water injection well.
Utility model content
