Top drive
drilling equipment is a new-style drilling system,With the use of top
drive drilling equipment,the system allows drilling with triple stands
and reduces make-up and break-out time.It stands for the most advanced
manufacturing technology of petroleum drilling machinery and special
mechanic-electronic-hydraulic petroleum machinery. It is one of the
important measures to speed up petroleum and natural gas exploration,
increase recovery ratio and reduce drilling cost.
Innovative top-driving technology of Beijing Petroleum Machinery
Factory:
It adopts the advanced and mature
AC frequency-variable driving technology and has such advantages as
accurate torque and speed control. The driving mode of the electric
system is flexible and, on the drilling platform, the driller can
directly select the electromechanical running mode (without the
necessity to modify the user program or system parameter). This control
mode is convenient and flexible and it is firstly innovated by Beijing
Petroleum Machinery
Factory.

| Technical
characteristics |
It can drill 28m long once,When
touching resistance and touching sticking,it may connect the drilling
pipe immediately,rotating and circulating.
It can implement
back redressing and snubbing redressing.
The drilling tool can work
in a wide range and it is helpful to reduce drill sticking accidents;
Since
it has remotely-controlled internal blowout control mechanism, the well
control is safe;
It can work continuously in a locked running mode
at rated
torque;
The single and double-motor running modes can be changed over to
each other easily;
The technical parameters are set reasonable and
its automation degree is high and the programs run reliable. |
