Below by embodiment, technical scheme of the present invention is described in further detail.
The specific embodiment
A kind of method that deep well high pressure aeration reactor inner core and internals are installed simultaneously of the present invention may further comprise the steps:
The first step, preparation of construction, on the promptly mounted reactor steel drum of the well head of institute's installation, set up earlier wellhead platform empty in the band, adopt conventional method that institute's installation well location is carried out azimuthal measurement again and locate and on described wellhead platform, mark, the through hole that described interior sky supplies described inner core cylindrical shell to pass when being installation.That is to say, in preparation of construction, mainly carry out azimuthal measurement location and wellhead platform and set up two preparations.
In this specific embodiment, the diameter of its deep well high pressure aeration reactor steel drum be 3200mm, wall thickness be 20mm, deeply for 92m; And the diameter of inner core cylindrical shell is 1600mm (internal diameter), and wall thickness is 12mm, and long is 77.555m; Herein, the inner core of indication comprises inner core cylindrical shell and attached thereon 1 secondary aspiration tube, and the internals of indication just are mounted in 9 pipelines of inner core inner barrel.
(1) azimuthal measurement location.
Central point with 2#, 1# well is a benchmark, the center line of two mouthfuls of wells is communicated with and prolongs as North and South direction, the factory north of also promptly designing the AB coordinate system to, go out the east-west direction of the well location of constructing again with transit survey, with 45 ° of rotation of coordinate, paint mark again at mounted reactor steel drum bung.
(2) wellhead platform is set up.
For saving cost, the wellhead platform of installation is still used the i iron platform when steel drum is installed, and just changes interior sky into 168 * 168cm, and welds the peripheral frame of an annulus as this wellhead platform with thickness for the 12mm steel plate.During installation, wellhead platform should be held on fully on the steel drum and with the steel drum welding and link.Simultaneously, for ease of operation, mat formation with steel plate or plank in the surface of described wellhead platform, and the external diameter of the described wellhead platform in back of mating formation is 4m.
In addition, because the interior sky of this wellhead platform is 168cm * 168cm, and the gas-vapor mix controller of deep well high pressure aeration reactor is installed in the bottom of the inner core of being installed, and being provided with for described internals in this gas-vapor mix controller is the installing hole of many piping erection, and the reservation eyelet of the described internals of being reserved in described installing hole and the inner core of installation is corresponding.Thereby when setting up wellhead platform, elder generation lifts the gas-vapor mix controller in the mounted steel drum of institute and carries out temporary fixed.That is to say, be provided with the installing hole of installing for described internals in the described gas-vapor mix controller, accordingly, after described inner core being docked on this gas-vapor mix controller, in described inner core, reserve the preformed hole that internals are installed.After the reinforcing ring of steel drum bung installed, then suspension bracket was in place, earlier hung in the gas-vapor mix controller in the steel drum and carried out temporary fixedly with steel plate and inner walls of steel drums, set up wellhead platform again above the steel drum bung afterwards.
Be noted that, before the gas-vapor mix controller is packed in lifting into, should make up the aqueous vapor mixture control earlier.Gas-vapor mix controller in this specific embodiment is provided by Canada, and it divides two-layer up and down, and every layer is divided into two semicircles again, needs on-the-spot combination.Before the combination, set up a combined platform at the scene earlier, establish interim bracing frame on the platform and be used to support semicircle controller, this interim bracing frame is also fixed with concrete and ground with the level gauge levelling.At first, the semicircle of getting two identical numberings winches on the work in combination platform, and during combination, need using up and down at the bottom of two support rings and two support rings distance on earth is 2210 ± 3mm.In two round groups up and down of gas-vapor mix controller to after good, height is 5042mm, each inter-module connects with junction plate, and it is elliptical aperture that upper and lower side carries out fixedly connected and corresponding bolt hole with bolt, and its lower end bolt is tightened, and upper end bolt hand-tight make-up gets final product, like this, two parts are adjusted two-part distance up and down automatically by the elliptical aperture surplus about allowing under the deadweight effect, fixed between bolt two ends and nut with the electrical pads solid welding, to prevent nut loosening in the operation process.Be noted that: will guarantee 3 principles during combination: 1. make up used support ring and want level, error is less than 2mm; 2. the external diameter that makes up used support ring can not be greater than design load; 3. the combination back guarantees that bucket internal diameter is not less than the design internal diameter in it.
Simultaneously, after wellhead platform is set up, should with in the azimuthal measurement location fixed each orientation with foreign punch mark on this wellhead platform.
Second step, with the aeration reactor inner core of required installation and internals from bottom to up correspondence be divided into a plurality of groups of sections, when sinking to installing, adopt conventional lifting and connect high method inner core and internals are divided into groups, and inner core and internals of each group section are installed simultaneously, the whole inner core outside also is provided with the multiple tracks reinforcing ring.In the present embodiment, inner core top nozzle is provided with 3 road reinforcing rings.
At first, will form each group section that described internals promptly are installed in many pipelines in the described inner core earlier, by coupling assembling and by standard component of the fixing composition of the status requirement corresponding flat that installs and fixes.In the present embodiment, tube length is 9m in the standard combination of described inner core, weighs 4.3 tons, and heavily about altogether 43 tons of the whole inner core that a plurality of groups of sections are formed (having deducted buoyancy weight) adopts 130 tons of mobile cranes to winch to well location and connects height piecemeal during lifting.Described internals have 5 aspiration tube and 4 gutters, and 9 pipeline enclosures of its each group section are dividing plate, junction plate etc. by coupling assembling, and form a standard component by the status requirement corresponding flat fixation binding that installs and fixes.
In the present embodiment, described internals comprise 5 aspiration tube and 4 gutters, and wherein, 4 one-level aspiration tube and 4 gutters all join with the air sparger of gas-vapor mix controller, adopt the manual arc welding fixing.43 inches one-level aspiration tube and 4 gutters are combined into many group segment standard parts by the installation dimension requirement that designs on ground, each group section upper end is provided with grid spacer, the lower end is provided with interim support bar and location-plate, connects when high, cuts off interim support bar and docks with mounted pipeline.In addition, also having 1 diameter is that 2 inches secondary aspiration tube and gutter is welded together, simultaneously this root secondary aspiration tube is also corresponding is made up of a plurality of groups of sections, and this root secondary aspiration tube uses the steel plate of 100 * 150 * 12mm to be connected with gutter respectively every 10m or its each group section.In the present embodiment, secondary air-blowing pipe range is that 75m and each group length are 6.2-7.2m, divides 11 joints to connect to form whole pipeline up and down successively.
Secondly, divide into groups from bottom to up described aeration reactor inner core and internals are hocketed to sink to installing simultaneously, during sinking, described inner core and internals lift and will guarantee the verticality of sinking respectively.In the sinking process, internals directly are shelved on the inner core.
(1) one or more groups of sections of lifting sinking earlier and temporary fixed inner core bottom, again one of correspondence or the internals that connect a plurality of groups of high sections are sunk to packing in the reservation eyelet of mounted inner core and carry out centering, leveling, the height of each group section of described inner core is big more, the group section of this disposable installation inner core is few more, and the assurance internals can be packed in the described reservation eyelet accurately, easily.
Because the original construction technology of employing is very difficult with the preformed hole that internals are inserted in the inner core, then in the present embodiment original mounting process is improved further.Earlier by two group sections of designing requirement lifting sinking inner core bottom, at first the inner core of two group sections and internals are connect height and connect and guarantee whole verticality when high, lift again afterwards; During lifting, adopting conventional hanging device is that mobile crane also lifts with conventional hanging method, before the lifting, on the outer wall of two group section inner cores and apart from the position of upper port 1m 4 hangers is installed symmetrically earlier, the bracket of this hanger double as support simultaneously usefulness.In the present embodiment, the hanger of being installed on its inner core is of a size of: high 30cm, and long 20cm, thick 25mm, shear strength is 30 * 2 * 0.8T=48T/, the lift heavy that 4 hangers can bear is bigger than the weight that need lift the inner core of two group sections and internals.And lifting hole(eyelet) place shearing resistance height is greater than 10cm, and the shear strength at lifting hole(eyelet) place is 2.5 * 10 * 2 * 0.8T=40.0T/, and the lift heavy that 4 hangers can bear lifts more than the big 76T of weight of the inner core of two group sections and internals than need; Lift with 4 diameter 28mm wire rope.The suspension centre place is provided with 300 * 300 * 20mm blind plate and does local the reinforcement, prevents inner core local distortion.Simultaneously, with a high cross lifting of the Type B i iron processing shoulder pole of 36cm, guarantee that suspension centre is vertically stressed.
The lifting back that sinks to putting in place is carried out temporary fixedly at the construction well head, specifically be the well cabinet frame that becomes empty 168cm * 168cm in 1 with 2 * 4 No. 36 i iron assembly weldings, and the well cabinet frame is held on an institute mounted steel drum center suitable for reading, and fix with the steel drum welding.Four angle of cut places of well cabinet frame are with the channel-section steel circle that to be welded into 1 diameter be 1680cm, and guiding is used with locating rack when sinking as inner core.After sinking to putting in place, the hanger of the inner core bracket of holding concurrently is held on the well head i iron well cabinet frame, in order to temporary fixed inner core.After two group sections of lifting sinking earlier and temporary fixed inner core bottom, two groups of internals of corresponding again installation, and internals are inserted in the preformed hole of inner core and carried out centering, leveling, so both guaranteed the smooth installation of internals, guaranteed again that internals can not influence the planeness that internals are installed because of welding slag falls on the support ring of gas-vapor mix controller.
An other diameter is 2 inches, length invests on the inner core for the secondary aspiration tube of 75m, this root secondary aspiration tube is being installed from the position of steel drum upper support top surface of ring 3.175m and is being installed on the inner core, and this root secondary aspiration tube to sink together with inner core be that itself and inner core are installed simultaneously.To the east of fixing 0 degree outer tube of this root aspiration tube on the position of steel drum center radian 250mm, each group section one of weldering bracing frame in the middle of 5m and inner core, the verticality requirement is the same with inner core; And manual electric arc welding is taked in the welding of this root aspiration tube, single face welding, two-sides forming.
The high mode that connects of adjacent two group section inner cores and internals is welding, before the welding, rivet earlier, after the riveted joint, with 2 transit observations, guarantee that inner core, internals connect the verticality when high, simultaneously with the absolute altitude place of gas-vapor mix controller orientation (four direction) vertical extent until inner core top 409.33m.The high riveted joint of interior socket joint, welding procedure is: with the 25T mobile crane one group of high inner core group section of connect is winched to the steel drum bung and vertically locatees riveted joint earlier, it connects high verticality and is controlled at 1/1000 by designing requirement, measure the verticality of the high inner core group section that connects with 2 transit four directions, surpass 2mm as perpendicularity deviation, then carrying out jacking aspect the inclination with jack, adjust, or high this group section one side cut with oxyacetylene metal-cutting, the limit is adjusted, the limit is measured, until its perpendicularity deviation of transit survey less than 2mm, relocate riveted joint afterwards, unfitness of butt joint is controlled in the 2mm; After the riveted joint of location, it is fixing to adopt the manual arc double welding to tap into the row welding again.
(2) inner core and the internals of a plurality of groups of sections of residue sink are installed in lifting successively: whenever connect the inner core of a high group section, correspondingly again connect highly to internals that should the section of group, afterwards whole inner core and internals behind the connecing height are sunk simultaneously.The lifting of its inner core and internals, connect high mode and lifting, connect in the high process specific requirement all with step (1) in identical, successively connect certain high group section inner core of connect and internals high and fixedly connected good after, again whole inner core behind the connecing height and internals are lifted sinking simultaneously, step during its lifting is sunk and points for attention all with step (1) in identical.It is noted that, before lifting is sunk, should be earlier connect hanger and bracket be installed on that high group inner core group section, this Lifting Lug Structure, effect and installation site all with step (1) in identical; And when lifting is sunk, also need to reject earlier hanger and the bracket that is supported on this moment on the well head well cabinet frame.Along with the continuous increase of inner core weight, the weight capacity of bracket is also progressively strengthened.In the actual use, hanger also can double as supports the bracket of usefulness.To sum up, inner core sinks to taking the fixing method of wellhead platform, and the central point that will control inner core does not depart from.
In the present embodiment, the whole internals that will connect behind the height with the 130T mobile crane lift sinking with inner core, require equally suspension centre and the circumference length that is fixed on inner core or internals symmetrically and evenly, highly consistent.Strict with steel ruler, level gauge measurement setting-out, prevent that inner core from departing from the center of circle and inclination, sinks internals with inner core after suspender is in place.
Because the inwall of already installed steel drum bottom is provided with two support rings up and down, and the internal diameter of upper support ring is less than the internal diameter of lower support ring; And correspondence is provided with two flange up and down on the controller of interior tube bottom, and the diameter of upper flange plate is greater than the diameter of lower flange.After finally installing, two support rings up and down of steel drum bottom are two flange up and down on the corresponding support and control device respectively.Thereby when the upper support ring on the approaching described steel drum of the lower flange on controller bottom inner core sinks down into it, interim suspention is internals fixedly, successively inner core and internals are lifted sinking respectively, and in the sinking process, the internals bottom does not directly contact with interior tube bottom; After the lower flange on the controller is by described upper support ring, internals directly are held on the inner core, simultaneously lift sinking with inner core and internals this moment; At last with all group section inner cores, internals are in place and inner core, internals position proofreaied and correct after, remove described wellhead platform again.
In the present embodiment, when inner core sinks down into lower flange on the controller apart from the upper support ring 0.5-1.0m position on the steel drum, utilize the well head hoisting bracket that the interim suspention of internals is fixing, and slowly descend with the 130T mobile crane inner core of slinging, the Chain block of well head suspension bracket suspention internals follows inner core slowly to descend again, with internals weight do not drop down onto on the inner core, vertical distance is that 30-60cm is a principle between inner core and internals, to reduce the off normal influence of internals to inner core, reduce the weight of internals, prevent that controller is out of shape because of load-bearing is excessive inner core.And after the lower flange on the controller is by the upper support ring 1-100cm on the steel drum, internals directly can be held on the inner core, inner core, internals lift sinking simultaneously.After inner core sinks to putting in place the most at last, require correction position, remove wellhead platform again.
After the whole sinking of inner core puts in place, inner core is temporarily fixed on the inner walls of steel drums earlier.Afterwards, support the lamina tecti of inner core by 4 bearing ribs of even laying, one end of its bearing rib and inner core welding are fixing, the other end fix by pre-buried channel-section steel column and channel-section steel column and bearing rib between with how linking with 2 blocks of angle steel, and centre, its underpart is weldingly fixed on the steel drum end face.In addition, bearing rib also can be installed after internals and external pipe install again.
In addition, it should be noted that before removing wellhead platform 4 water service pipes also need be installed.Installation for equally distributed 4 water service pipes is then very simple, and described water service pipe below is held on the upper support ring, and the top links with lifting pumping plant water inlet pipe.Take single segmentation to connect the job practices that high lifting is sunk, lift with the 25T mobile crane, the manual electric arc welding single-sided welding, double-faced forming, a supporting frame of being made up of the 16cm channel-section steel is set on wellhead platform during lifting, the bracket of 2 20 * 15 * 2cm of balanced welding on the water service pipe that is lifted, bracket are put on the channel-section steel supporting frame in order to temporary fixed.In addition, the position of 4 feedwater supports and the position consistency of water service pipe, the welding of an end of described feedwater support and inner core, the other end is held on the end face of steel drum and can be free to slide.
The above; it only is preferred embodiment of the present invention; be not that the present invention is imposed any restrictions, everyly any simple modification that above embodiment did, change and equivalent structure changed, all still belong in the protection domain of technical solution of the present invention according to the technology of the present invention essence.
