DRILL-IN FLUIDI ZA IZRADU HORIZONTALNIH BUŠOTINA
Description (Dublin Core)
eng
Main objective of horizontal driling is to place a drain-hole for a long distance within the pay zone to enhance productivity or injectivity. In drilling horizontal wells, more serious problems appear than in drilling vertical wells. These problems are: poor hole cleaning, excessive torque and drag, hole filling, pipe stucking, wellbore instability, loss of circulation, formation damage, poor cement job, and difficulties at logging jobs. From that reason, successful drilling and production of horizontal well depends largely on the fluid used during drilling and completion phases.
Several new fluids, that fulfill some or all of required properties (hole cleaning, cutting suspension, good lubrication, and relative low formation damage), are presented in this paper.

Glavna svrha horizontalnog bušenja je izrada kanala bušotine, unutar proizvodne zone radi povećanja njene proizvodnosti ili injek-tivnosti. Pri izradi horizontalnih bušotina javljaju se ozbiljniji problemi, nego pri izradi vertikalnih bušotina. Ti problemi su slijedeći: loše čišćenje kanala bušotine, prekomjerna torzija i nateg, ispunjavanje kanala bušotine, gubitak cirkulacije, oštećenje stijene, nekvalitetna cemcntacija i poteškoća pri mjerenjima u kanalu bušotine. Zbog toga, uspješna izrada kanalu horizontalne bušotine i njezina proizvodnost u velikoj mjeri ovise o fluidu koji se primijenjuje tijekom bušenja i opremanja bušotine.
U radu je opisano nekoliko novih tipova fluida koji uglavnom imaju svojstva potrebna tijekom izrade horizontalnih bušotina (djelotvorno čišćenje kanala bušotine, zadržavanja krhotina u suspenziji, dobro podmazivanje i relativno malo oštećenje proizvodnih stijena).
