Test equipment integrated protection device.
Background technique
The various types of downhole tool minimum diameters in oil field are Φ 46mm, and test instrument maximum outside diameter Φ 44mm,
Downhole tool is influenced fouling condition easily occur by water injection time and injection water quality etc..Downhole tool internal diameter fouling 1mm will lead to
Its annular minimum diameter is reduced to Φ 44mm, easily causes test equipment underground is stuck and vibration damage instrument situation.Above-mentioned feelings
Condition, gently then causes test equipment damage of internal device, cable, the concussion of steel wire Tensile and reduce service life, it is heavy then cause
The trouble of lost tool in hole accident such as block, fall test equipment, cable, steel wire, operation need to be taken to handle when serious, and then influences full well water filling effect
Fruit seriously affects water filling qualification rate.
Previous processing mode be by well-flushing, under all kinds of drifting devices processing, devote considerable time, financial resources, manpower, efficiency
Low, longevity of service, large labor intensity, and effect is not unobvious.Therefore, invent a kind of technology more it is mature it is perfect, safe and reliable,
Can effectively anti-sticking, unfreezing and damping device, be more advantageous to the popularization and application in oil field in this way, reduce economic loss, further mention
High testing efficiency.
Summary of the invention
Stuck in underground in order to solve to be easy existing for existing test equipment, unfreezing success rate is low, and meet card vibration and
Damage test equipment the problems such as, the invention proposes one kind be convenient to fieldwide flood well test work, prevent card resistance shake and
Caused test equipment damage and test equipment are stuck in pit shaft, can effectively ensure that smooth unfreezing, it is raw to reduce enterprise
The working hour of cost and consuming, the protective device of reliable performance are produced, specific technical solution is as follows:
Downhole testing instrument integrated protection device, including the jointing being connect with test equipment bottom, the jointing with
Antiseize device main body connects, and the side on the upper part of antiseize device main body is provided with the limit opening of upper end, antiseize device main body
Lower section is provided with the limit opening of lower end, the limit opening of the upper end and lower end at the upper other side opposite with the limit opening of upper end
Limit opening at be equipped with steel ball, the antiseize device body interior is equipped with stop screw at the other side opposite with steel ball,
Each limit opening of antiseize device body interior is constituted between respective stop screw respectively shrinks channel, shrinks built in channel
There is spring, the spring one end is contacted with stop screw, and the other end is by the corresponding each limit opening of steel ball overhead, and the one of steel ball
Part is exposed through limit opening, and rest part is limited opening limit fastener and is shrinking in channel；Similarly, antiseize device main body
Lower part on level set that there are two vertical other two in channel that shrink with upper part to shrink channel, this other two shrink
Also limit opening, stop screw, steel ball and spring are respectively equipped in channel；The lower end of the antiseize device main body is provided with internal screw thread
Groove, the internal screw thread groove are connect with shock-absorbing connection threaded one end, and shock-absorbing connection is socketed in inside shock absorption outer cylinder, and damping connects
