Abstract

"PROCESSO E SISTEMA PARA A VARIAçãO PASSO A PASSO DE FLUXO DE FLUIDO EM UM POçO". Um processo para a variação passo a passo de fluxo de fluido em um poço utiliza uma pluralidade de válvulas de furo descendente, as quais têm orifícios de diferentes tamanhos nos corpos de válvula, de modo que fluxo de fluido pode ser variado pelo fechamento parcial de uma ou de mais válvulas. O processo pode ser usado para o teste de poços de gás, de modo que os retardos de armazenamento do furo de sondagem, causados pela compressão de gás e/ou expansão de gás na tubulação de produção são minimizados."PROCESS AND SYSTEM FOR STEP BY STEP FLOW FLOW VARIATION". A process for step-by-step variation of fluid flow in a well utilizes a plurality of down-hole valves, which have different sized holes in the valve bodies, so that fluid flow can be varied by partially closing a valve. or more valves. The process can be used for gas well testing, so that drillhole storage delays caused by gas compression and / or gas expansion in the production pipeline are minimized.
