Description

DESCRIZIONE dell’invenzione industriale avente per TITOLO: DESCRIPTION of the industrial invention with TITLE:

Complesso di sistemi automatici e robotizzati innovativi gestiti tramite un software di gestione dedicato atto a automatizzare in modo completo le operazioni di un qualsiasi impianto di perforazione del sottosuolo in tutte le sue fasi (lavoro, perforazione, manovra, tubaggio ecc...) in grado anche di recuperare energia durante alcune di esse con un sistema tipo “kersh” per risparmiare carburante e consumo delle parti. Complex of innovative automatic and robotic systems managed through a dedicated management software designed to fully automate the operations of any subsurface drilling rig in all its phases (work, drilling, maneuvering, piping, etc.) capable of also to recover energy during some of them with a “kersh” type system to save fuel and consumption of parts.

I cunei automatici ACA00100 descritti in questo brevetto servono per incuneare, trattenere e centrare sull’ asse del pozzo i diametri di diversi tubolari, offrendo la possibilità di incuneare e trattenere una gamma di diametri molto più ampia rispetto a quanto ottenuto fino ad ora e, cosa molto importante, non necessitando di cambiare i porta inserti (e gli inserti) ogniqualvolta si deve cambiare il diametro da incuneare. The ACA00100 automatic wedges described in this patent are used to wedge, retain and center the diameters of different tubulars on the axis of the well, offering the possibility of wedging and retaining a much wider range of diameters than what has been obtained up to now and, what very important, as there is no need to change the insert holders (and the inserts) every time you have to change the diameter to be wedged.

L’insieme è composto da un corpo, detto vaso porta cunei fisso(13), inserito dentro un vaso conico esistente nel piano di lavoro o dentro il vaso conico di una tavola rotary dell’impianto di perforazione non indicato nel disegno. Dentro il vaso porta cunei fisso(13) sono inseriti i porta cunei secondari(7) che vengono movimentati su piani inclinati del vaso porta cunei da cilindri idraulici o pneumatici(3). Dentro i cunei secondari(7) sono inseriti i cunei primardi 0) dentro i quali sono inseriti i pettini dentati di presa (2). Tali pettini hanno la peculiarità di poter prendere diversi diametri come indicato nelle tavole A, ,B, C, D, E, F, e/o altri diametri intermedi senza dover essere cambiati (ora The whole is composed of a body, called fixed wedge holder vessel (13), inserted into a conical vessel existing in the work surface or inside the conical vessel of a rotary table of the drilling rig not indicated in the drawing. Inside the fixed wedge holder (13) are inserted the secondary wedge holders (7) which are moved on inclined planes of the wedge holder by hydraulic or pneumatic cylinders (3). Inside the secondary wedges (7) are inserted the primary wedges 0) inside which the toothed gripping combs (2) are inserted. These combs have the peculiarity of being able to take different diameters as indicated in tables A,, B, C, D, E, F, and / or other intermediate diameters without having to be changed (now

porta cunei vengono sostituiti manualmente a seconda dei diametri da prendere); perché questi inserti, con un sistema di rotazione che può essere a ingranaggi o a leva o altro vengono fatti ruotare sul loro asse presentando la faccia con i pettini(2) la cui curva è più adatta al diametro di presa del tubolare. wedge holders are replaced manually according to the diameters to be taken); because these inserts, with a rotation system which can be gear or lever or other, are made to rotate on their axis presenting the face with the combs (2) whose curve is more suitable for the gripping diameter of the tubular.

Tale sistema di scorrimento di diversi cunei uno dentro l’altro ha permesso inoltre di poter aumentare la capacità di passaggio e di presa per diametri diversi, partendo da un diametro di 1” 1⁄2 (A) arrivando fino al diametro di 26” (F) attraverso tutti i diametri intermedi B,C,D,E, e altri diametri senza cambiare i porta cunei e gli inserti di presa. This sliding system of several wedges one inside the other has also made it possible to increase the passage and gripping capacity for different diameters, starting from a diameter of 1 "1⁄2 (A) up to a diameter of 26" ( F) through all intermediate diameters B, C, D, E, and other diameters without changing the wedge holders and gripping inserts.

Tale sistema inoltre, per come è conformato dal punto di vista idraulico, fa anche da centratore dei tubolari durante la fase di presa Moreover, this system, as it is shaped from the hydraulic point of view, also acts as a centering device for the tubulars during the gripping phase.

I caricatori delle riduzioni, scalpelli, stabilizzatori e/o altri tubolari speciali del disegno 122-25-000 sono due, uno per le riduzioni e gli scalpelli e uno per gli stabilizzatori, composti ciascuno da un telaio di base(1a), fissato sul piano sonda in posizione adeguata, dentro il quale scorre un telaio secondario(2a) nel quale sono ricavate le sedi(8a) per il montaggio in verticale dei vari componenti necessari alla perforazione. Essi, mediante motore elettrico, riduttore e cremagliera (7a,6a,4a), o idraulicamente oppure con altro sistema di spostamento, vengono posizionati a centro pozzo per permettere alla testa motrice di prelevare il componente necessario all’ operazione richiesta. Finita tale operazione ritornano nella posizione di riposo lasciando libero il centro pozzo per l'inserimento degli altri componenti. I componenti nelle sedi dei caricatori sono bloccati dentro le loro sedi con dei tasselli (5a)tenuti in posizione da molle, per impedire che il componente ruoti durante il prelevamento da parte della testa motrice (top drive) There are two loaders for the reductions, chisels, stabilizers and / or other special tubulars of the 122-25-000 design, one for the reductions and the chisels and one for the stabilizers, each composed of a base frame (1a), fixed on the probe surface in a suitable position, inside which slides a secondary frame (2a) in which the seats (8a) are obtained for the vertical assembly of the various components necessary for drilling. They, by means of an electric motor, reducer and rack (7a, 6a, 4a), or hydraulically or with another displacement system, are positioned in the center of the well to allow the drive head to pick up the component necessary for the required operation. Once this operation is finished, they return to the rest position, leaving the well center free for the insertion of the other components. The components in the magazine seats are locked inside their seats with plugs (5a) held in position by springs, to prevent the component from rotating during pickup by the head drive (top drive)

Il sistema centratore e para spruzzi 122-21-000 è un insieme composto da un base guida carrello (1 b), da un telaio scorrevole (8a) alla cui estremità vi sono due semi gusci(6b e 5b) che si chiudono attorno ai tubolari quando vengono spinti dal cilindro idraulico(7b) contro di essi. L’insieme è montato in posizione adeguata per poter essere, quando richiesto, spinto a centro pozzo tramite un martinetto idraulico o pneumatico(7b)o motore elettrico e riduttore. Durante la manovra di estrazione dei tubolari quindi, questo strumento viene spinto al centro pozzo e si chiude automaticamente attorno ai due manicotti dei tubolari che sono in estrazione. Quando i tubolari vengono svitati questo strumento trattiene gli spruzzi del fango al suo interno aspirandolo con un tubo, creando a valle del stesso il vuoto e convogliando il fango dentro al serbatoio di raccolta fango. Il sistema è dotato di questo aspiratore per facilitare l’estrazione e l’aspirazione del fango senza sporcare il piano sonda. Durante la manovra di discesa in pozzo e quando i due manicotti devono essere avvitati questo stesso attrezzo, spinto a centro pozzo dal martinetto(7b), si chiude sui due manicotti dei tubolari allineandoli con i bracci centratori (2b e 3b) facilitandone avvitamento. The centering and splash guard system 122-21-000 is a set consisting of a trolley guide base (1 b), a sliding frame (8a) at the end of which there are two half shells (6b and 5b) which close around the tubular when pushed against them by the hydraulic cylinder (7b). The assembly is mounted in a suitable position to be, when required, pushed to the center of the well by means of a hydraulic or pneumatic jack (7b) or electric motor and reducer. Therefore, during the extraction maneuver of the tubulars, this instrument is pushed to the center of the well and automatically closes around the two sleeves of the tubulars that are being extracted. When the tubulars are unscrewed, this tool retains the splashes of mud inside it by sucking it with a tube, creating a vacuum downstream of the same and conveying the mud into the mud collection tank. The system is equipped with this aspirator to facilitate the extraction and suction of the mud without dirtying the probe surface. During the descent into the well and when the two sleeves have to be screwed, this same tool, pushed to the center of the well by the jack (7b), closes on the two sleeves of the tubulars, aligning them with the centering arms (2b and 3b), facilitating screwing.

Il sistema di morse per il bloccaggio e lo sbloccaggio delle giunzioni dei tubolari è montato sul piano sonda e serve per sbloccare i giunti dei tubolari durante la movimentazione dei tubolari in manuale e in automatico. Ha gli inserti di dei tubolari variabili per adattarsi a qualsiasi diametro di presa The clamp system for locking and unlocking the tubular joints is mounted on the probe surface and is used to unlock the tubular joints during the manual and automatic handling of the tubulars. It has variable tubular inserts to adapt to any grip diameter

superiore che permette una rotazione di 60° e più per sbloccare in un sol colpo i giunti. La stessa morsa permette, con un motore idraulico che fa ruotare una ghiera, di fare lo svitamento completo dei giunti. top that allows a rotation of 60 ° and more to unlock the joints in one go. The same vice allows, with a hydraulic motor that rotates a ring nut, to completely unscrew the joints.

Il sistema magnetico per l'individuazione del collegamento tra i due manicotti filettati maschi/femmina dei tubolari serve per automatizzare la manovra di estrazione dei tubolari ed è composto da due anelli di ferro di diametro sufficiente per il passaggio dei tubolari, magnetizzati in modo permanente tra i quali è inserito un terzo anello di ottone sul quale è montata una bobina dalla quale escono due contatti. The magnetic system for identifying the connection between the two male / female threaded sleeves of the tubulars is used to automate the extraction maneuver of the tubulars and is composed of two iron rings of sufficient diameter for the passage of the tubulars, permanently magnetized between which is inserted a third brass ring on which a coil is mounted from which two contacts come out.

Il principio genera un campo magnetico stabile naturale a 360 gradi. The principle generates a 360 degree natural stable magnetic field.

Quando una variazione di massa passa all’interno degli anelli e quindi dal campo magnetico naturale questa interferisce con il campo stesso. Tale interferenza energizza la bobina per una frazione di tempo producendo una corrente elettrica. When a change in mass passes inside the rings and therefore from the natural magnetic field, it interferes with the field itself. This interference energizes the coil for a fraction of the time producing an electric current.

Tale corrente elettrica corrisponde ad una variazione di massa e quindi individua il collegamento tra i due manicotti perché la zona filettata, che si trova nella zona di collegamento, ha massa inferiore rispetto al corpo del manicotto. This electric current corresponds to a mass variation and therefore identifies the connection between the two sleeves because the threaded area, which is located in the connection area, has a lower mass than the sleeve body.

Registrando questa variazione e rapportandola ad uno spostamento dopo l’individuazione del picco di corrente, il sistema ci permette di posizionare la giunzione esattamente tra le due morse di sbloccaggio per poter effettuare quindi lo svitamento o la separazione dei due tubolari. By recording this variation and relating it to a movement after the identification of the current peak, the system allows us to position the junction exactly between the two release vices in order to then be able to unscrew or separate the two tubes.

Sistema a recupero di energia durante la discesa in pozzo Energy recovery system during the descent into the well

Questo sistema permette il recupero di energia trasformandola in energia elettrica durante la discesa in pozzo dei tubolari. This system allows the recovery of energy by transforming it into electrical energy during the descent into the well of the tubulars.

Nella perforazione tradizionale durante la discesa in pozzo, il peso dei tubolari viene frenato da pattini su tamburi dell’argano e addizionalmente da freni elettromagnetici o idraulici innestati sull’ albero del tamburo principale. In traditional drilling during the descent into the well, the weight of the tubulars is braked by skids on the drums of the winch and additionally by electromagnetic or hydraulic brakes engaged on the shaft of the main drum.

Nel nostro caso, utilizzando un sistema di cilindri per il tiro e la spinta dei tubolari, l’olio che esce in pressione dai cilindri quando avviene la discesa in pozzo dei tubolari, viene inviato alle pompe a ingranaggi (che alimentano i cilindri durante il tiro per il sollevamento dei tubolari) che, girando, in questo caso, a rovescio, fanno girare il motore elettrico collegato alle pompe. Il tipo di motore elettrico scelto diventa generatore di corrente che, attraverso gli inverter, genera corrente che viene rimandata all’uscita dei generatori diesel che alimentano tutte le utenze dell’impianto di perforazione aggiungendo altra energia elettrica oltre a quella già dispensata per alimentare i vari componenti dell’impianto In our case, using a system of cylinders for pulling and pushing the tubulars, the oil that comes out under pressure from the cylinders when the tubulars descend into the well, is sent to the gear pumps (which feed the cylinders during the traction). for lifting the tubulars) which, in this case turning backwards, turn the electric motor connected to the pumps. The type of electric motor chosen becomes a current generator which, through the inverters, generates current that is sent back to the output of the diesel generators that power all the users of the drilling rig, adding more electricity in addition to the one already dispensed to power the various plant components

il software di gestione e supervisore è un programma sviluppato per questo tipo di impianto, che riceve e tiene sotto controllo tutte le informazioni provenienti dai vari sistemi omogeneizzandoli tra di loro per ottenere una gestione completamente automatizzata dell’impianto di perforazione. Significa nel nostro settore che il perforatore, una volta settato il sistema manualmente, non deve più necessariamente agire su bottoni leve o joystick per effettuare le operazioni di perforazione o manipolazione dei tubolari, risultando un sistema tecnologicamente innovativo. the management and supervisor software is a program developed for this type of plant, which receives and keeps under control all the information coming from the various systems, homogenizing them with each other to obtain a fully automated management of the drilling rig. In our sector, this means that once the system has been set manually, the punch no longer necessarily has to act on the buttons, levers or joysticks to carry out the drilling or manipulation of the tubulars, resulting in a technologically innovative system.

Inoltre questo sistema permette anche di poter operare su un impianto di perforazione con l’operatore a distanza (senza l’operatore a bordo quindi) effettuando tutte le operazioni di perforazione automaticamente e controllando le operazioni di perforazione e estrazione delle aste e altro con telecamere posizionate sull'impianto stesso nelle posizioni strategiche come ad esempio, controllando il buon funzionamento dei generatori diesel mediante telemetria In addition, this system also allows you to operate on a drilling rig with the remote operator (without the operator on board therefore) carrying out all drilling operations automatically and controlling the drilling and extraction operations of the rods and more with positioned cameras. on the plant itself in strategic positions such as, for example, checking the proper functioning of diesel generators by telemetry

During the descent maneuver of the tubulars into the well, when the driving head, after having received one or a series of tubulars parked there from the maneuvering bridge, descends to screw them to the thread of the tubular present on the probe surface inside the automatic wedges, the thread of the downward tubular, it can be offset with respect to the tubular present inside the automatic wedges. The centering system intervenes by embracing the two bodies of the tubulars with the two half-shells (5b and 6b), and referring to the fixed sleeve locked in the automatic wedges guides the other by centering it with the arms (2b and 3b) and preparing it for screwing. In the other case, during the extraction maneuver of the tubulars from the well, often drilling mud remains inside them. During unscrewing, this system, by wrapping the two half-shells (5b and 6b) around the two sleeves of the tubular, prevents the uncontrolled outflow of the mud by keeping it inside and conveying it to the drain provided on the bottom of the centering device. Suction system of the mud that may have remained inside the tubulars and from the splash guard during the extraction maneuver and the subsequent unscrewing, by means of a vacuum pump or centrifugal pump, to prevent the mud from scattering on the probe surface, dispersing on the ground and polluting in doing so and making the countertop dirty and slippery System composed of 122-25-000 loaders with body (1a) with tanks (8a) mounted on sliding body (2a), which house the reductions, chisels, stabilizers and other complementary and special equipment necessary for drilling or for the completion of the well, mounted on the work surface of the plant and which allows the automatic positioning alternatively in the center of the well through the racks (3a, 4a) and motor and reducer (7a, 6a) of all the complementary components described above which are necessary for drilling, and which are taken and screwed to compose the battery of drilling tubes or unscrewed and taken when the tubes are extracted from the well; or when completing the same with the need for special equipment that is inserted from time to time in the magazine slots.

The system consists of two permanently magnetized iron rings of sufficient diameter for the passage of the various diameters of the tubulars, between which a third diamagnetic steel ring is inserted, on which a coil of copper wire is wound, the ends of which they are made to go outside in order to pick up an electric current signal. The invention generates a natural and permanent 360 degree stable magnetic field, which remains stable when a uniform magnetic mass passes inside it, but instead generates current and sends a more or less intense signal when a different metal mass passes inside the field. magnetic. This variation indicates the junction between the two sleeves in the exact point where they are screwed; indication necessary to position the clamps for the unlocking and subsequent automatic unscrewing of the threads. Energy recovery system generated during the tubular descent into the well. The pressurized oil that comes out of the cylinder or from the pulling and pushing cylinders when the weight of the tubulars falls into the well, is sent to the hydraulic pumps whose gears turn the electric motor by turning. The type of engine chosen, driven by the hydraulic pump, generates current which, through the inverters, is sent back to the output of the diesel generators that power the entire system, adding electricity to that already absorbed by the various components of the system System composed of a management and supervisor software that receives and keeps under control all the information coming from the various systems, homogenizing them among them.
