> Exploration for many years has pursued goal,
because time well drilling can produce greatly crowds the pressure and
the abrasion, restricts has hardly met the hairstyle real-time drill
rod remote biography method the application. I n t e l l e S e
the r v company develops the drill rod high speed data remote
biography system has solved the drill rod coupling problem, truly has
realized along the drill rod real-time mine shaft data transmission.
The new remote biography system core is the special design
drilling rod coupling inserts the type non- contact type coupler,
caused this system the before hard wire type data transmission method
more reliable, the structure to be more reliable than, moreover the
data output rate far was higher than the mud pulse remote biography
system which at present uses.
In the past 50 years, the technical development enabled in the
well drilling process real-time to provide the formation evaluation
material and 井眼 the guidance data, thus enormously has saved the
drilling machine time and the well drilling operation cost.
Along with drills the oil well logging and along with drills the
measurement system use mud pulse remote biography the mine shaft
survey data transfer ground, has met the real time data transmission
needs in the certain degree. But because the mud pulse remote
biography transmission speed only has 6 ~ 10 bytes/seconds, has
limited the mine shaft survey data transmissibility in the very great
degree, caused the mine shaft transmission the survey data resolution
to be low, has limited certain data crowded measuring techniques, like
earthquake and formation evaluation measuring technique application.
The excessively low mud pulse remote biography data rate reduces
the well drilling progress, the increase cost of operation.
Regarding use froth/pneumatic drill 井液 owes the balanced
well drilling method, then cannot use the mud pulse remote biography
method transmission mine shaft survey data, therefore the oil gas
continuously unceasingly is seeking the alternative means, realizes in
the true significance to be high speed real-time along with drills the
data transmission.
Because the mine shaft drills the column to have many junctions,
if uses the hard segment way transmission signal, then unavoidably can
appear the breakdown, therefore, I n t e l l e S e the r v company
develops the new generation of drill rod high speed data remote
biography system by the non- contact induction way took between the
drilling rod coupling transmits the data method, the data transmission
speed reaches as high as for 2 megabytes/seconds. The drill rod
data transmission use induction way is the most basic electromagnetic
induction.
I n t e l l e S e the r v system has installed the armor wire
along each drill rod endophragm. In the drilling rod coupling
beginnings and ends, wire "sinks to the" drill rod thread 连接?
Buries the drilling rod coupling the coil wire terminal the male
thread 台肩 企口 in. Two neighboring drilling rod couplings
coil connection is extremely close. In the inductance
transmission mode, two contain inserts the type toroidal coil the
neighboring drilling rod coupling 阳螺纹端 and 阴螺?the end
separately includes the transmitting coil and the receive coil.
In order to prevent the transmission signal attenuation unwanted
signal, I n t e l l S e the r v high speed real-time drill rod data
remote biography system uses many mine shafts signal enhancement
processing electric circuit I n t e l l i L i n k according to the
actual situation, guarantees the successful transmission data.
滑环 has installed a induction coil installment in the ground,
withdraws transmits from the mine shaft to the ground useful signal,
then transforms the signal the conventional high speed data
transmission. The well head 滑环 transmits the mine shaft
survey data through the satellite or the network any need place.
New generation of drill rod remote biography system I n t e l l
i S e r v is the signalling speed which at present develops is
quickest along with drills the high speed real-time data remote
biography system, estimated will realize 商业?the application in
2004. The new drill rod transmission technology will have the
significant influence to the oil gas exploration, after will use the
new remote biography technology, will enhance the well drilling speed,
will reduce the operation cost. Intelligent drill rod system
itself has formed a mine shaft network system, can realize in the well
drilling process with each kind of mine shaft tool and in the survey
sensor true significance real-time bidirectional communication, thus
achieved the economy effectively appraises the oil gas pool and the
real-time precise guidance well drilling path goal.
