API DRILLING JAR FOR OILFIELD
QJ—K type drilling jar while drilling is a fully mechanical jar
with integrated upper and lower strikes. It has the advantages of
simple structure, short length, convenient maintenance and
QJ-A type drilling jar while drilling is also a kind of
all-mechanical jar. Its structural features are that the release
force can be adjusted on-site, the setting is accurate, and it is
easy to disassemble and assemble, which is suitable for drilling
while working under various circumstances.
QY—A type drilling jar while drilling is a fully hydraulic type
drilling jar while drilling with upper and lower strikes. It has
many advantages such as simple operation, large shock force,
convenient adjustment, high connection strength, stable
performance, safety and reliability, and easy maintenance. This
product does not cause false shocks when drilling, drilling,
receiving a single or touching the bottom of the well, and its
hydraulic delay allows the operator to dynamically adjust the size
of the upper and lower strike force. Fully sealed oil bath
lubrication helps reduce wear and increase service life. In
addition. Its position in the drill string assembly is relatively
free, and it can be placed in various positions such as tension,
neutral point, and compression. It can meet the needs of drilling
operations under various operating conditions such as land and sea.
YJ-A type drilling jar while drilling is also a kind of jar with up
and down. It uses the principle of hydromechanics, which overcomes
the shortcomings of pure hydraulic jars or mechanical jars. The
advantages of both are absorbed. The position in the drill string
is relatively free, and it can be placed in various positions such
as tension, neutral point and compression, and the operation is
simple. Easy to use. The mechanical locking and hydraulic delay
work together during the upward stroke. The mechanical locking
device can prevent tool wear and false vibration during drilling
operations. The locking force can be adjusted at the wellhead. The
hydraulic delay action allows the operator to adjust the magnitude
of the upward strike force; the downward strike process has only a
mechanical effect. Its release force can also be adjusted at the
wellhead. In addition. This product has a compact structure and
high connection strength. Reliable sealing. Fully sealed oil bath
lubrication is beneficial to reduce wear and improve service life.
Is an advanced new underground accident handling tool.
The split type drilling jar while drilling includes SS type upper
drill while drilling (hydraulic) and SX type lower drill while
drilling (mechanical). They can be used together. It can also be
used separately in accordance with the needs of downhole operation.
It is one of the indispensable tools for drilling operations such
as directional wells and complex wells.
CS type super striker is an advanced hydraulic salvage tool. It is
compared with the up-drilling device. It has the advantages of
simple structure and stable performance. It can be used together
with the shock accelerator to obtain a more significant shock
effect. It is a new type of upward shock tool in drilling
engineering such as petroleum and geological exploration.
DX-A ground striker is a new type of groun
