Abstract

"MéTODOS PARA ESTABILIZAR UM FURO DE POçO DURANTE A PERFURAçãO COM FLUIDO DE PERFURAçãO à BASE DE áGUA ATRAVéS DAS FORMAçõES ARGILOSAS E PARA PERFURAR UM FURO DE SONDAGEM EM UMA FORMAçãO ARGILOSA, FLUIDO DE PERFURAçãO PARA PERFURAR UM FURO DE POçO EM UMA FORMAçãO SUBTERRâNEA, E, MéTODO PARA INTENSIFICAR A ESTABILIDADE DE UM FURO DE POçO PENETRANDO UMA FORMAçãO ARGILOSA". é divulgado um método que fornece estabilidade melhorada para furos de poço durante a perfuração em formações argilosas com fluidos de perfuração com base em água. O método compreende adicionar ao fluido de perfuração um composto da invenção tendo a capacidade em água para gerar uma membrana altamente eficaz em materiais argilosos. O composto é solúvel no fluido de perfuração pelo menos no pH em que o composto é adicionado ao fluido de perfuração ou está no fluido de perfuração, mas é insolúvel na água nos poros das formações argilosas, ou pelo menos no pH da água em tais poros."METHODS FOR STABILIZING A WELL HOLE DURING THE WATER-BASED DRILLING FLUID THROUGH CLAY FORMATION AND FOR DRILLING A DRILLING HOLE IN A CLEAR FORMATION, A PERFORMANCE DRILLING FLUID , METHOD FOR INTENSIFYING THE STABILITY OF A WELL HOLE PENETRATING A CRAZY FORMATION ". Disclosed is a method that provides improved stability for wellbores while drilling in clay formations with water-based drilling fluids. The method comprises adding to the drilling fluid a compound of the invention having the ability in water to generate a highly effective membrane in clay materials. The compound is soluble in the drilling fluid at least at the pH at which the compound is added to the drilling fluid or is in the drilling fluid, but is water-insoluble in the pores of the clay formations, or at least in the pH of water in such pores. .
