Abstract
- Described is horizontal drilling in the world and data on such activity in Hungary. Results show that there is an increase of such activity in spite of complex problems in drilling and completion of horizontal wells. Since these wells are often drilled in partialy exhausted hydrocarbon fluid reservoirs with slightly over-balanced or even with under-balanced conditions, there is an increased danger of blowouts. Prevention methods and suggested procedures are elaborated.<br />Opisano je vodoravno bušenje u svijetu i dati su podaci o toj djelatnosti u Mađarskoj. Rezultati pokazuju da se povećava ta djelatnost uprkos složenim problemima kod izrade i opremanja vodoravnih bušotina. Kako se ove bušotine izrađuju u djelomično iscrpena ležišta ugljikovodika uz isplake s neznatnim pretlakom ili čak i podtlakom na bušene stijene, povećana je opasnost od nekontroliranih erupcija fluida. Opisani su načini sprečavanja tih pojava i peporučeni postupci kod toga.
