Abstract
Bušenje i opremanje bušotina savitljivim tubingom danas je realnost u svijetu proizvodnje nafte i plina. Ovakve operacije donose velike uštede novca i vremena, ali sa sobom nose i probleme u vidu izvijanja tubinga i mogućih zaglava niza. Ovaj diplomski rad će detaljno prikazati prirodu izvijanja tubinga, utjecaj dodatnog trenja koje pri tom nastaje, te zasebno izvijanje u vertikalnoj, zakrivljenoj i vodoravnoj dionici bušotine. Izvijanje savitljivog tubinga može se pojaviti u svakoj dionici bušotine (vertikalnoj, zakrivljenoj i vodoravnoj), ali kritična sila pri kojoj nastupa deformacija bit će različita za pojedinu dionicu kanala bušotine. Spiralno izvijanje će se dogoditi kada kanal bušotine ograničava daljnju prostornu deformaciju tlačno opterećenog tubinga. Dva su temeljna pitanja na koja je potrebno dati podrobna objašnjenja, a to su: Kolika će biti vrijednost kritične sile izvijanja? Kakva će biti deformacija tubinga i kako će to utjecati na cjelokupan proces primjene tubnga?
Abstract (english)
Abstract Drilling and completion of horizontal wells using coiled tubing are normal applying operations nowadays in the oil and gas industry. These technologies bring about significant saving, but they also raise new problems, such as buckling and "lockup" of coiled tubing in the wellbore. This Master work will analyze, in detail, the nature of coiled tubing buckling and frictional drag in horizontal wells (including vertical, buildup, and horizontal sections), and present the equations to predict bit weight/packer load, maximum horizontal section that can be drilled, and coiled tubing "lockup". Coiled tubing buckling may occur in any wellbore section (vertical, horizontal and buildup section). However, the axial compressive load to initiate the buckling is different for different wellbore sections. The two fundamental questions about tubing buckling are: What is the critical load? What is the post buckled configuration?
