Description

"UNIDADES DE SEPARAÇÃO GAS-LÍQUIDO E COMPRESSÃO/BOMBEIO MONTÁVEIS EM POÇO DE PRODUÇÃO E POÇO DE INJEÇÃO"  "GAS-LIQUID SEPARATION AND COMPRESSION / PUMP SEPARATION UNITS IN PRODUCTION WELL AND INJECTION WELL"
Campo da Invenção  Field of the Invention
[01] A presente invenção trata de soluções submarinas individuais a serem aplicadas em poço de produção para separação gás-líquido e poço de injeção para compressão ou bombeio da corrente de gás ou água em sistemas submarinos de exploração de petróleo. [01] The present invention relates to individual subsea solutions to be applied in production wells for gas-liquid separation and injection wells for compressing or pumping gas or water streams in subsea oil exploration systems.
Descrição da Invenção  Description of the Invention
[02] Conforme esquematizado na Figura 1 , a presente invenção trata de uma unidade de separação gás-líquido (1 ) que é conectada a uma base adaptadora de produção BAP ou "Tubing Head" (2), ou alternativamente em uma cabeça de poço com suspensor de coluna previamente instalada no poço de produção. [02] As shown in Figure 1, the present invention relates to a gas-liquid separation unit (1) which is connected to a BAP or Tubing Head production adapter base (2), or alternatively to a wellhead. with column hanger previously installed in the production well.
[03] Referida unidade de separação gás-líquido (1 ) compreende ainda as barreiras necessárias à segurança e o controle do poço, de forma a dispensar o uso de uma árvore de natal molhada { "X-tree'). [03] Said gas-liquid separation unit (1) further comprises the necessary safety barriers and well control in order to dispense with the use of a wet X-tree.
[04] A unidade de separação gás-líquido (1 ) direciona o gás separado para uma linha de fluxo (3) através de um mandril da BAP (2). Alternativamente, a dita unidade de separação gás-líquido (1 ) pode também prover o mandril para conexão da linha de fluxo (3) para a saída do gás. Assim procedendo, o líquido separado é enviado a uma segunda linha de fluxo via um segundo mandril na BAP. Adicionalmente, a unidade de separação gás-líquido (1 ) também pode prover o mandril para conexão da linha de fluxo de líquido.  [04] The gas-liquid separation unit (1) directs the separated gas to a flow line (3) through a BAP mandrel (2). Alternatively, said gas-liquid separation unit (1) may also provide the flow line connection mandrel (3) for the gas outlet. In doing so, the separated liquid is sent to a second flow line via a second mandrel in the BAP. Additionally, the gas-liquid separation unit (1) can also provide the mandrel for connection of the liquid flow line.
[05] A aplicação dessa solução segundo a presente invenção é especialmente indicada para sistemas de produção antecipada (SPA) ou testes de longa duração (TLD). Neste caso, o mandril para saída de líquido da unidade de separação gás-líquido (1 ) poderá ser provido no seu topo, facilitando a conexão com o SPA ou TLD para envio da corrente de líquido às facilidades de superfície. [05] The application of this solution according to the present invention is especially indicated for early production systems (SPA) or long term testing (TLD). In this case, the liquid outlet chuck of the gas-liquid separation unit (1) may be provided at its top, facilitating the connection to the SPA or TLD to send the liquid stream to the surface facilities.
[06] No poço de injeção, a solução segundo a presente invenção compreende uma unidade de compressão ou bombeamento (4) que é conectada diretamente a uma BAP ou { "Tubing Head') (5) ou a uma cabeça de poço com suspensor de coluna. A linha de fluxo contendo o gás ou a água a ser injetado pode ser conectada à BAP ou { "Tubing Head') (5) ou, alternativamente, diretamente à unidade de compressão/bombeio (4). O gás ou líquido é então comprimido ou bombeado para o poço injetor. [06] In the injection well, the solution according to the present invention comprises a compression or pumping unit (4) which is connected directly to a BAP or Tubing Head (5) or a well with column hanger. The flow line containing the gas or water to be injected may be connected to the BAP or Tubing Head (5) or alternatively directly to the compression / pumping unit (4) .The gas or liquid is then compressed or pumped into the injector well.
[07] Faz-se importante notar que referida unidade de compressão/bombeio (4) também contém as barreiras necessárias à segurança e ao controle do poço, o que também torna dispensável o uso de uma árvore de natal molhada { "X-tree'). [07] It is important to note that said compression / pumping unit (4) also contains the necessary barriers to safety and well control, which also makes it unnecessary to use a wet X-tree. ).
[08] Como pode ser apreciado pelos técnicos versados na arte, a solução segundo a presente invenção é facilmente aplicável a cenários com vários poços onde o gás e líquidos produzidos ou a serem injetados podem ser distribuídos através de um arranjo submarino contendo equipamentos tradicionais, tais como manifolds e PLEMs.  [08] As may be appreciated by those skilled in the art, the solution according to the present invention is easily applicable to multi-well scenarios where gas and liquids produced or to be injected can be distributed through an underwater arrangement containing traditional equipment such as as manifolds and PLEMs.
