Description
Technical field
The utility model relates to a kind of pair of quadruple board platform construction A type drilling derrick, belongs to drilling derrick technical field.Relate to and increase quadruple board platform quantity, increase operating space, the A type drilling derrick that can operate the how single column connecting into.
Background technology
Drilling derrick is a kind of metal truss structure with certain altitude and span, it is the important component part of rig, mainly by derrick main body, crown's nest, quadruple board platform, man-like shelf and derrick annex etc., formed, in drilling process for laying overhead traveling crane, hang traveling system, hang drilling tool and remove the operations such as drilling rod, setting of casing, processing down-hole accident, bearing various operating loads.
A type drilling derrick is a kind of of derrick, and current A type drilling derrick only has a quadruple board platform, and for depositing column, bearing column weight, the space that derrick provides can only operate 3 single columns that are linked to be at most.And the assistance platforms such as standpipe operating desk are the platforms that standpipe etc. is operated, and do not have the function that quadruple board platform is deposited column, born operating load.
Adopt single quadruple board platform A type drilling derrick to carry out constructing operation, it is few that the column of derrick license single safety operation connects single quantity, and column is short, the column number of times of unloading just many, efficiency is low, is unfavorable for that wellbore construction carries the needs of effect.Two quadruple board platform construction A type drilling derricks can operate 4 single columns that are linked to be, and the column that single connects is long, can reduce the column number of times of unloading, and saves drilling time, improves drilling efficiency.
Certain document is mentioned the special derrick scheme of special construction rig, in order to meet the needs of different operating modes, can different quadruple board platforms be set for different operating modes, two quadruple board platform roles of double-jointing pipe quadruple board platform in its scheme and single drilling rod quadruple board platform are identical, function overlaps each other, corresponding construction column connects single quantity to be reduced, in two quadruple board platforms, each participation work only has a quadruple board platform, say in essence two installation sites that have been still single quadruple board platform structure choice, be still in fact single quadruple board platform construction, constructing with two quadruple board platforms is diverse concept.The quadruple board platform of the in-service rig of reality is all a quadruple board platform, and three installation position selection, adjust position during use.Utilize two quadruple board platforms to play a role simultaneously, jointly complete the imagination not yet discovery at present of a construction manipulation process, current applicable cases is: have multipoint quadruple board platform, the two quadruple board platform constructing structures that simultaneously do not work.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of pair of quadruple board platform construction A type drilling derrick.
A quadruple board platform construction open front churn derrick, mutually assembles connection by crown's nest, derrick main body, high-order quadruple board platform, derrick annex, low level quadruple board platform, man-like shelf and forms.Crown's nest connecting well frame body, main body connects high-order quadruple board platform, derrick annex, low level quadruple board platform and man-like shelf, and man-like shelf connects drilling floor surface; L1 is low level quadruple board platform to vertical distance, the L2 of drilling floor surface, be high-order quadruple board platform is that crown's nest is to the vertical distance of drilling floor surface to vertical distance, the L3 of drilling floor surface.
Overhead traveling crane is installed on crown's nest, and derrick main body and man-like shelf are arranged on base, and drilling floor surface is the work plane of base;
Man-like shelf plays the effect of stressed fulcrum and buffering when derrick telescoping and base, after hoist completion frame and base, play the effect of supporting righting, overhead traveling crane is mainly the effect that assembly pulley is installed, derrick and base are main stressed members, quadruple board platform plays a supportive role, and is the playground of high-altitude application personnel constructing operation simultaneously;
Extend drilling derrick principal length size, crown's nest strengthens to the vertical distance L3 of drilling floor surface, increases derrick operating space, thereby the stroke space of assurance derrick can be realized 4 single columns that are linked to be are operated; Increase a quadruple board platform; form high-order and two quadruple board platforms of low level; like this; when 4 single columns that are 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 for the storage support of column, guarantee 4 single safe storage that are linked to be column; Remove and deposit and can guarantee safety, just realized drilling derrick to 4 single safety operations that are linked to be column;
High-order quadruple board platform and two quadruple board platforms of low level quadruple board platform need to play a role simultaneously and just can make 4 single upright column job practicess be achieved; Two quadruple board platforms work, and its corresponding construction manipulation process has marked change, and the construction of two quadruple board platforms coordinates and plays a role with supporting new construction technology.
The beneficial effects of the utility model are: 1, utilize to increase two quadruple board platform structures after a quadruple board platform all for the depositing and carrying of column, realization is to 4 single safety operations that are linked to be column.2, for deep-well, ultradeep well drilling well, can reduce the column number of times of unloading, improve the speed that makes a trip, improve drilling efficiency, shorten drilling period.3, can make full use of other ancillary facility of rig, reliable, economize on the use of funds.
