Abstract

Primarna kontrola tlaka u bušotini vrši se putem hidrostatičkog tlaka stupca fluida u kanalu bušotine. Ako je hidrostatički tlak manji od slojnog tlaka, vrlo će vjerojatno doći do dotoka slojnog fluida u kanal bušotine. Tada se pristupa gušenju bušotine. Tema ovog diplomskog rada je istodobna metoda gušenja bušotine i usporedba iste s inženjerskom metodom. U radu su slikovito prikazani koraci provođenja istodobne metode i, u svrhu boljeg razumijevanja, koraci provođenja inženjerske metode. Provedeni proračun razvoja tlaka na bušaćim šipkama i na ušću bušotine, s istim ulaznim podacima o bušotini, dotoku i svojstvima sloja, prikazuje osnovne razlike između dvije navedene metode. Razvoj tlaka prilikom provođenja obje navedene metode prikazan je na dijagramima koji prikazuju ponašanje tlaka na bušaćim šipkama i tlaka na ušću bušotine u ovisnosti o broju hodova pumpe.

Abstract: Hidrostatic pressure, which is result of the mud held in the annular space of well, is declared as the primary well control. If the hidrostatic pressure is lower than formation pressure kick will probably occur. Next step , if this happen, is well killing. The main subject of this thesis is concurrent method of well killing and comparison to wait and weight method. Main steps of concurrent and wait and weight method are shown and compared to each other. The calculation of drill pipe pressure and casing pressure, within same well, kick and formation characteristics, shows main differences between concurrent and wait and weight method. Pressure behavior is drawn on charts which show drill pipe and casing pressure related to volume pumped into the well.
