Description

“TUBO DE INJEÇÃO DE FLUIDO COM GOLA, PARA COLUNA DE ENSAIO, COM SISTEMA DE TRAVAMENTO POR BATENTE EM GAVETA DE CABEÇA DE POÇO DE PERFURAÇÃO”“FLUID INJECTION TUBE WITH COLLAR, FOR TEST COLUMN, WITH STOP LOCKING SYSTEM IN DRILL WELL HEAD DRAWER”

[001] Refere-se o presente relatório descritivo, a um pedido de patente de invenção para uma adaptação feita no tubo pelo qual é injetado o fluido pela coluna de ensaio em poço de perfuração. Como novidade o referido tubo de fluido recebe uma gola e, após rosqueado à caixa roscada da haste superior parcialmente exposta na cabeça do poço, formará um batente contra a gaveta fechada do BOP (sistema de prevenção de fluxo descontrolado).[001] The present specification refers to a patent application for an adaptation made in the tube through which the fluid is injected through the test column in a drilling well. As a novelty, the aforementioned fluid tube receives a collar and, after being screwed to the threaded box of the upper rod partially exposed at the wellhead, it will form a stop against the closed BOP drawer (uncontrolled flow prevention system).

[002] Após a injeção de fluido, para a etapa de ensaio (onde são determinadas as capacidades de absorção e fratura da rocha, a pressão imposta dentro do poço, durante o teste, causa uma força de baixo para cima, quando então a coluna de ensaio será impedida de ser expelida pelo travamento da gola do tubo contra a borda inferior da gaveta fechada do BOP.[002] After the fluid injection, for the test stage (where the absorption and fracture capacities of the rock are determined, the pressure imposed inside the well, during the test, causes a downward force, when then the column The test tube will be prevented from being expelled by locking the tube collar against the bottom edge of the closed BOP drawer.

ESTADO DA TÉCNICATECHNICAL STATUS

[003] Como é de conhecimento, durante a perfuração de poços em sistemas de sondagem, conforme o avanço algumas camadas atingidas pela coroa de perfuração devem ser ensaiadas, em etapa denominada “Teste de Absorção”. Pela ação do fluido no fundo do poço será estabelecido um histórico contendo as características do solo, para posterior análise pelos responsáveis, para o prosseguimento das operações de perfuração dentro das normas de segurança.[003] As is well known, while drilling wells in drilling systems, as the advance progresses, some layers reached by the drilling crown must be tested, in a stage called “Absorption Test”. Through the action of the fluid at the bottom of the well, a history will be established containing the characteristics of the soil, for later analysis by those responsible, for the continuation of drilling operations within safety standards.

[004] A título exemplificativo, pode ser citado o documento de patente PI 8108500-1 denominado “ELEMENTO DE TUBO INTERIOR PARA UM[004] As an example, patent document PI 8108500-1 called “ELEMENT OF INTERIOR TUBE FOR A

APARELHO DE ENSAIO DE SONDAGEM E PROCESSO PARA A FABRICAÇÃO DE UM ELEMENTO DE TUBO INFERIOR” depositado emPROBE TESTING PROCEDURE AND PROCESS FOR THE MANUFACTURE OF A LOWER TUBE ELEMENT ”deposited in

29.12.1981.12.29.1981.

[005] Para o procedimento de ensaio, uma coluna tubular denominada coluna de ensaio é inserida no poço de perfuração adentro, mantendo sua haste superior parcialmente exposta na cabeça do poço com sua caixa roscada posicionada para receber o rosqueamento do bocal roscado de um tubo de injeção de fluido. Na plataforma, o tubo de injeção de fluido por sua vez recebe o acoplamento do mangote de uma bomba ligada a um reservatório de fluido e, em seguida, o referido tubo de injeção de fluido é envolto pelo fechamento das gavetas BOP (sistema de prevenção de influxos e ligação entre o revestimento e a cabeça do poço), formando uma vedação sobre a referida cabeça do poço.[005] For the test procedure, a tubular column called the test column is inserted into the drilling well, keeping its upper stem partially exposed at the well head with its threaded box positioned to receive the threaded nozzle of a pipe. fluid injection. On the platform, the fluid injection tube in turn receives the hose coupling from a pump connected to a fluid reservoir, and then the fluid injection tube is surrounded by the closing of the BOP drawers ( inflows and connection between the casing and the wellhead), forming a seal over the wellhead.

[006] Após fechadas as gavetas do BOP em volta do tubo de injeção de fluido, a bomba é acionada para a injeção, passante coluna de ensaio e incidindo contra o fundo do poço, pressurizando-o. Nessa condição, todo o interior do poço, assim como a cabeça do poço, bem como o BOP, fechado pelas gavetas, é submetido a grandes pressões que, impostas a partir do fundo refletem contra o fundo da coluna de ensaio forçando-a continuamente para cima.[006] After the BOP drawers are closed around the fluid injection tube, the pump is activated for injection, passing a test column and impacting the bottom of the well, pressurizing it. In this condition, the entire interior of the well, as well as the wellhead, as well as the BOP, closed by the drawers, is subjected to great pressures that, imposed from the bottom, reflect against the bottom of the test column, forcing it continuously to up.

[007] Tal condição, juntamente com a parede lisa da coluna de ensaio, favorecem que esta última vença as forças de atrito de travamento, formada pelas gavetas fechadas sobre a coluna. Ao ser empurrada para cima, a referida coluna de ensaio desliza pela passagem em volta do tubo de fluido podendo mover-se em relação à sua posição original planejada na plataforma, comprometendo assim a execução do teste e trazendo riscos à operação e às equipes presentes na plataforma de operações.[007] This condition, together with the smooth wall of the test column, favors the latter to overcome the locking friction forces, formed by the closed drawers on the column. When pushed upwards, the said test column slides through the passage around the fluid tube and can move in relation to its original position planned on the platform, thus compromising the execution of the test and bringing risks to the operation and the teams present in the operations platform.

OBJETIVO DA PATENTEPATENT OBJECTIVE

[008] O tubo de injeção de fluido em questão, através de uma adaptação em seu corpo vem provocar um inédito sistema de travamento que irá impedir que a coluna de ensaio, sob forte pressão, “escape” pelas gavetas BOP (sistema de prevenção de “Blow Out”).[008] The fluid injection tube in question, through an adaptation in its body, causes an unprecedented locking system that will prevent the test column, under strong pressure, from “escaping” through the BOP drawers (system of prevention of “Blow Out”).

[009] Explicado superficialmente, passa o tubo de injeção de fluido e o sistema que o envolve, motivos desse pedido de patente, a serem melhor detalhados através dos desenhos anexos, pelos quais se vêem:[009] Explained superficially, the fluid injection tube and the system that surrounds it, reasons for this patent application, to be better detailed through the attached drawings, which show:

[022] Em conformidade com os desenhos anexos, o “TUBO DE INJEÇÃO DE FLUIDO COM GOLA, PARA COLUNA DE ENSAIO, COM SISTEMA[022] In accordance with the attached drawings, the “COLLECTION FLUID INJECTION TUBE, FOR TEST COLUMN, WITH SYSTEM

DE TRAVAMENTO POR BATENTE EM GAVETA DE CABEÇA DE POÇO DE PERFURAÇÃO”, objeto desse presente pedido de patente de invenção, constitui-se a partir de um tubo de injeção de fluido (1) para uso em coluna de ensaio (E) de equipamento de sondagem, o qual possui extremidade superior com bocal roscado (2) seguido de uma cabeça (3) dotada de entrada de fluido (4). Em sua extremidade inferior, o tubo de fluido (1) possui um bocal roscado (5) internamente e, imediatamente acima incorpora uma gola externa (6), como mostram as figuras 1, 2 e 3.LOCKING BY STOP IN DRILLING HEAD DRAWER ”, object of this present patent application, consists of a fluid injection tube (1) for use in test column (E) of borehole, which has an upper end with a threaded nozzle (2) followed by a head (3) equipped with a fluid inlet (4). At its lower end, the fluid tube (1) has a threaded nozzle (5) internally and, immediately above it incorporates an external collar (6), as shown in figures 1, 2 and 3.

[023] Tendo a gola (4) incorporada como novidade, o tubo de injeção de fluido (1), assim constituído irá possibilitar um inédito sistema de travamento por batente para a coluna de ensaio (E) usada na etapa de ensaio ou de testes, para formação de histórico das características de solo (S) em poços perfurados (P), no trabalho de sondagem gás/óleo.[023] Having the collar (4) incorporated as a novelty, the fluid injection tube (1), thus constituted, will enable an unprecedented stop locking system for the test column (E) used in the test or tests stage , for the formation of a history of soil characteristics (S) in drilled wells (P), in the gas / oil drilling work.

[024] Como mostram as figuras 4 e 5, a coluna de ensaio (E) é direcionada e introduzida pelo sistema de elevação do equipamento de sondagem (não mostrado) poço (P) adentro, ultrapassando sua cabeça (CA), onde encontram-se instaladas as gavetas (G) BOP (sistema de prevenção de “Blow Out”). A coluna de ensaio (E) deixa exposta parcialmente sua haste superior com a caixa roscada (C) livre. Em seguida, pelo bocal roscado (5) de sua extremidade inferior, o tubo de injeção de fluido (1) é rosqueado à caixa roscada (C) da haste superior acoplando-se assim à coluna de ensaio (E), como mostram as figuras 6 e 7.[024] As shown in figures 4 and 5, the test column (E) is directed and introduced by the lifting equipment of the drilling equipment (not shown) into the well (P), surpassing its head (CA), where they are located if installed the (G) BOP drawers (“Blow Out” prevention system). The test column (E) partially exposes its upper stem with the threaded housing (C) free. Then, through the threaded nozzle (5) of its lower end, the fluid injection tube (1) is threaded to the threaded box (C) of the upper stem, thus coupling to the test column (E), as shown in the figures 6 and 7.

[025] Segue-se o fechamento das gavetas (G) que envolvem a cabeça do poço (P) e são faceadas por suas bordas no corpo do tubo de injeção de fluido (1), formando a vedação contra fluxo descontrolado de gás. Nessa condição, a gola (6) do tubo de injeção de fluido (1), como mostra em especial o detalhe B da figura 7, posiciona-se logo abaixo da borda das gavetas (G) fechadas.[025] The drawers (G), which surround the wellhead (P), are closed by their edges on the body of the fluid injection tube (1), forming the seal against uncontrolled gas flow. In this condition, the collar (6) of the fluid injection tube (1), as shown in particular in detail B of figure 7, is positioned just below the edge of the closed drawers (G).

[026] Após receber pela entrada de fluido (4), a conexão do mangote (M) da bomba ligada ao reservatório de fluido (não mostrados), é iniciada a injeção para o ensaio, como mostram as figuras 8 e 9, quando o fluido passa pelo tubo de injeção de fluido (1) e também pela coluna de ensaio (E) até atingir o fundo do poço (P). Em casos de grandes pressões impostas pelo fluido a partir do fundo do poço (P), a coluna de ensaio (E) tende a ser empurrada para cima e, por suas paredes lisas, vence as forças de atrito entre si mesma e a gaveta do BOP fechada e desliza, sendo forçada a escapar das referidas gavetas (G), como mostra a figura 10 e seu detalhe ampliado C.[026] After receiving through the fluid inlet (4), the hose connection (M) of the pump connected to the fluid reservoir (not shown), the injection for the test is initiated, as shown in figures 8 and 9, when the fluid passes through the fluid injection tube (1) and also through the test column (E) until it reaches the bottom of the well (P). In cases of large pressures imposed by the fluid from the bottom of the well (P), the test column (E) tends to be pushed upwards and, due to its smooth walls, the frictional forces between itself and the drawer overcome BOP closed and slides, being forced to escape from the above drawers (G), as shown in figure 10 and its enlarged detail C.

[027] Nessa condição a coluna de ensaio (E), ao subir, carrega o tubo de injeção de fluido (1) acoplado que, por sua gola (6), segundo o sistema proposto nesse pedido de patente, trava-se sob a borda inferior das gavetas (G). Como ilustra o detalhe D da figura 11, o travamento em sistema de batente entre gola (6) e borda inferior das gavetas (G) impede que a coluna de ensaio (E) vença a vedação das gavetas (G) e seja expelida.[027] In this condition, the test column (E), when rising, carries the coupled fluid injection tube (1) which, by its collar (6), according to the system proposed in that patent application, locks under the bottom edge of the drawers (G). As shown in detail D of figure 11, the stop in a stop system between collar (6) and bottom edge of the drawers (G) prevents the test column (E) from overcoming the seal of the drawers (G) and being expelled.

[028] Estando a coluna de ensaio (E) devidamente travada, através do sistema de sensores instalados na sonda, pode ser efetuado o ensaio com exatidão sem prejuízo do histórico das características do solo no poço (P) perfurado[028] If the test column (E) is properly locked, using the sensor system installed in the probe, the test can be carried out accurately without prejudice to the history of the soil characteristics in the well (P) drilled
