Abstract

Le apparecchiature di flusso (20) di un mandrino perforato (18) sono temporaneamente sigillate mediante elementi a tappo (34) che sono fatte di un materiale sacrificabile, ad esempio zinco, alluminio e magnesio. Gli elementi a tappo impediscono che il fluido sporco di completamento passi attraverso il vaglio mentre scorre entro il foro, proteggendo così il vaglio dall'otturazione. Mentre il mandrino del vaglio è temporaneamente sigillato dagli elementi a tappo, il fluido di pulitura viene fatto circolare attraverso una batteria o colonna di aste di lavoro ed è fatto ritornare attraverso l'elemento anulare o foro fra il vaglio e la cavità di perforazione per rimuovere la torta di filtraggio, i detriti di perforazione e materiale di perdita di circolazione. Dopo che l'elemento anulare è stato pulito, esso viene riempito con una soluzione acida o caustica, che discioglie gli elementi a tappo sacrificabili. In una forma di realizzazione alternativa, ciascun tappo di tenuta ha una sacca di ventilazione (58) sigillata da una porzione di troncone (60) che sporge entro la cavità di mandrino. Le aperture di flusso del mandrino del vaglio sono aperte tagliando meccanicamente la porzione di troncone di ciascun elemento a tappo di tenuta.
