Description
Technical field
The A type drilling derrick the present invention relates to a kind of pair of quadruple board platform is constructed, belongs to drilling derrick technical field.It is related to increase by two
Layer number of units amount, increase working place, the A type drilling derrick that more single columns connecting into can be operated.
Background technology
Drilling derrick is a kind of metal truss structure with certain altitude and span, is the important component part of rig,
Mainly be made up of derrick main body, crown's nest, quadruple board platform, man-like shelf and derrick adnexa etc., be used for laying in drilling process overhead traveling crane,
Hang traveling system, suspension drilling tool carries out removing drilling rod, setting of casing, processes the operations such as down-hole accident, subject various operations and carry
Lotus.
A type drilling derrick is one kind of derrick, current A type drilling derrick only one of which quadruple board platform, be used for depositing column,
Bear column weight, the column that the space that derrick provides at most can only single to 3 be linked to be operates.And standpipe operating board etc.
Assistance platform, is the platform that standpipe etc. is operated, and does not have quadruple board platform and deposits column, bears the function of operating load.
Constructing operation is carried out using single quadruple board platform A type drilling derrick, it is single that derrick permits that the column of single safety operation connects
Radical amount is few, and column is short, and just many, efficiency is low for column number of times of unloading, and is unfavorable for that wellbore construction carries the needs of effect.Double quadruple board platforms
The column that construction A type drilling derrick can single to 4 be linked to be operates, and the column that single connects is long, can reduce column of unloading
Number of times, saves drilling time, improves drilling efficiency.
The special derrick scheme of special construction rig mentioned by certain document, in order to meet the needs of different operating modes, can be for not
Same operating mode setting different quadruple board platform, the double-jointing pipe quadruple board platform in its scheme and two quadruple board platform institutes of single drill pipe quadruple board platform
Work identical, function overlaps each other, corresponding construction column is coupled single quantity to be reduced, and participates in every time in two quadruple board platforms
Two installation sites that the only one of which quadruple board platform of work has been still essentially single quadruple board platform structure choice, are still substantially single
Quadruple board platform is constructed, and is diverse concept with the construction of double quadruple board platforms.The quadruple board platform of the in-service rig of reality is all a quadruple board platform,
Three installation position selection, are adjusted to position during use.Played a role using two quadruple board platforms simultaneously, jointly complete one
The imagination of construction manipulation process not yet finds at present, and current applicable cases are：There is multipoint quadruple board platform, do not act as simultaneously
Double quadruple board platform constructing structures.
Content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of pair of quadruple board platform construction A type drilling derrick.
A kind of pair of quadruple board platform construction open front churn derrick, attached by crown's nest, derrick main body, high-order quadruple board platform, derrick
Part, low level quadruple board platform, man-like shelf mutually assemble connection and form.Crown's nest connects derrick main body, and main body connects high-order quadruple board platform, well
Shelf attachment, low level quadruple board platform and man-like shelf, man-like shelf connects drilling floor surface；L1 for low level quadruple board platform to drilling floor surface vertical dimension,
L2 be high-order quadruple board platform to the vertical dimension of drilling floor surface, L3 for crown's nest to drilling floor surface vertical dimension.
Overhead traveling crane is installed on crown's nest, derrick main body and man-like shelf are arranged on base, and drilling floor surface is the work surface of base;
Man-like shelf plays fulcrum force and the effect of buffering in derrick telescoping and base, after raising completion frame and base
Play the effect supporting righting, overhead traveling crane is mainly the effect installing assembly pulley, and derrick and base are main stressed members, quadruple board platform
Play a supportive role, be the playground of high-altitude application personnel's constructing operation simultaneously；
Extend drilling derrick principal length size, vertical dimension L3 of crown's nest to drilling floor surface increases, and increases derrick operation
Space, thus ensure that the stroke space of derrick enables the column that be linked to be single to 4 and operates;Increase a quadruple board platform,
Form high-order and two quadruple board platforms of low level, so, when 4 single columns being linked to be are deposited, column lower end is placed on drilling floor surface,
Side by being placed on two quadruple board platforms, makes two quadruple board platforms can be used for the storage support of column it is ensured that 4 single are linked to be column
Safety deposit;Remove and deposit and can ensure safety, be achieved that the drilling derrick safety behaviour that is linked to be column single to 4
Make；
High-order quadruple board platform and two quadruple board platforms of low level quadruple board platform need to play a role simultaneously and could make 4 single upright column constructions
Method is achieved；Two quadruple board platforms work, and its corresponding construction manipulation process has significant changes, the construction of double quadruple board platforms with
Supporting new construction technology cooperation plays a role.
The invention has the beneficial effects as follows：1st, the double quadruple board platform structures after increasing a quadruple board platform are utilized all to be used for depositing of column
Put and carry, realize the safety operation that be linked to be column single to 4.2nd, it is used for deep-well, ultra-deep well drilling, it is possible to reduce unload vertical
Post number of times, improves the speed that makes a trip, and improves drilling efficiency, shortens drilling period.3rd, the other that can make full use of rig is supporting
Facility, reliable, saving fund.

Man-like shelf plays fulcrum force and the effect of buffering in derrick telescoping and base, after raising completion frame and base
Play the effect supporting righting, overhead traveling crane is mainly the effect installing assembly pulley, and derrick and base are main stressed members, quadruple board platform
Play a supportive role, be the playground of high-altitude application personnel's constructing operation simultaneously.
Extend drilling derrick principal length size, vertical dimension L3 that crown's nest 1 arrives drilling floor surface increases, increase derrick operation
Space, thus ensure that the stroke space of derrick enables the column that be linked to be single to 4 and operates.Increase a quadruple board platform,
Form high-order and two quadruple board platforms of low level, so, when 4 single columns being linked to be are deposited, column lower end is placed on drilling floor surface 7
On, side by being placed on two quadruple board platforms, makes two quadruple board platforms can be used for the storage support of column it is ensured that 4 single are linked to be
The safety of column is deposited.Remove and deposit and can ensure safety, be achieved that the drilling derrick safety that is linked to be column single to 4
Operation.
High-order quadruple board platform and two quadruple board platforms of low level quadruple board platform need to play a role simultaneously and could make 4 single upright column constructions
Method is achieved.Two quadruple board platforms work, and its corresponding construction manipulation process has significant changes, the construction of double quadruple board platforms with
Supporting new construction technology cooperation plays a role.
As described above, being explained to embodiments of the invention, but as long as essentially without depart from this
Bright inventive point and effect can have a lot of deformation, and this will be readily apparent to persons skilled in the art.Therefore, this
The variation of sample is also integrally incorporated within protection scope of the present invention.
