Description
Technical field
The utility model is related to petroleum drilling technology field, specifically relates to a kind of slide drilling system.
Background technology
During natural petroleum gas field, in order to exploit petroleum resources with minimum drilling hole number, or in order to reduce
The influence of ground and underground condition to natural petroleum gas field, 1930s petroleum gas worker utility model is non-
Peupendicular hole drilling technology, artificially offsets and gets into the cave in the earth formation as expected, forms directional well or horizontal well.
Realize that directional well, horizontal well are got into the cave mainly have following two clocks technology as expected in the earth formation at present：One is that rotation is led
To drilling technology, expected power or corner are produced in bit location, realization is bored by underground specific device in rotating condition
Direction is offset Jing Dong as expected.The advantage of this method is efficiency high of getting into the cave, and has the disadvantage that operating cost is higher, there is presently no in state
It is interior to use on a large scale.Two be oriented sliding drilling technology, in drilling process, keeps drill string not rotate, and is moved by underground is curved
Power drilling tool produces drill bit broken rock revolving force and drilled wellbore to the cheap power of anticipated orientation and corner.The advantage of this method is cost
Relatively low, more conventional drilling well merely add the locus after a curved mud motor and a measurement pit shaft skew
MWD, this method is current directional well, the mainstream technology of horizontal well use.The shortcoming of this method is during slide drilling, to bore
Head is not rotated with upper drill, but is slid axially along well, and drill bit relies on the power broken rock of helicoid hydraulic motor, because drill string keeps phase
To static, do not rotate, part drill string lies in pit shaft lower wall, stiction greatly, causes bit cutting formation rock
Energy can not effectively apply, while keeping mud motor in the wellbore with respect to the angle of high point（Tool-face）Stablize also more
Difficulty, shows that bit speed is slow in operation process, frequently adjustment tool-face angle wastes the plenty of time, is answered while occurring underground
Miscellaneous and accident possibility is also significantly increased.
In order to improve slide drilling speed and efficiency, industry generates underground vibrating method in recent years, by being bored in distance
A waterpower rocking equipment is installed additional at a certain distance from head, and part hydraulic energy is converted into " vibration " ability in drilling process,
A range of drill string " vibration " adjacent thereto is driven, so as to eliminate the stiction of post and pit shaft, raising is served and slides
The effect of dynamic bit speed and efficiency.This method is there is also some shortcomings simultaneously, and one is that the waterpower rocking equipment of underground has one
Fixed working life and chance of failure, can cause it is extra make a trip, add drilling time and expense, two be the work of the device
Come from hydraulic energy as energy, show as ground injection hydraulic pressure (pump pressure) increase in drilling process, often in 2-5MPa,
The well that part has been pumped very high, cannot use or only change the ground injection device of higher-capability, three be the party
Method can only drive a range of drill string " vibration " adjacent with underground vibrating device, it is impossible to eliminate the static friction of whole drill string
Power, causes effect bad, even without.
