Abstract
PROCESSO PARA OBTENçãO DE PERFIS DE TESTE DE AUSêNCIA DE VAZAMENTO E TESTE QUANTO A INTEGRIDADE DE FORMAçãO A PARTIR DE MEDIçõES LIMITADAS DA PRESSãO NO INTERIOR DA CAVIDADE A presente invenção introduz um processo que restabelece de forma eficiente a vantagem em tempo real das medições da pressão anular enquanto em perfuração (APWD) realizadas durante certas operações de perfuração que requerem que as bombas de circulação de lama sejam desligadas (uma condição de ''bombas desligadas''). O dado APWD, tal como medições da pressão, é obtido a partir de instrumentos e equipamentos eletrónicos correlatos no interior do BHA. Os dados APWD podem ser medidos, armazenados e mesmo processados no BHA durante uma condição de bombas desligadas para processamento ou comunicação subsequente de uma quantidade reduzida de dados para o perfurador junto a superfície.
