Abstract

zadnjih desetak godina broj operacija sa savitljivim tubingom rastao je eksponencijalno te tako čini jedan od najbrže rastućih područja unutar sektora istraživanja i proizvodnje nafte i plina. Prema ICoTA-i (engl. Intervention & Coiled Tubing Association) u 2018. godini u svijetu je bilo aktivno 2040 postrojenja za rad sa savitljivim tubingom, od čega je čak četvrtina smještena u Sjedinjenim Američkim Državama.
Savitljivi tubing izvrsno je rješenje za današnje potrebe opremanja i održavanja bušotina zato jer postoje mnogi zahtjevi za izradu ultra dubokih bušotina, zbog sve veće iscrpljenosti plićih ležišta, a i zbog sve veće eksploatacije nekonvencionalnih ležišta u kojima je potrebna velika duljina horizontalnog dijela kanala bušotine te velika kontaktna površina između kanala bušotine i ležišta.
U ovom radu biti će opisani pojedine operacije opremanja i održavanja kanala bušotine te dani prijedlozi sastava alata za sklapanje dubinskog niza alatki za obavljanje određene operacije u kanalu bušotine.

Abstract (english)

In the previous decade, the number of coiled tubing operations within the petroleum industry grew exponentially, making it one of the fastest growing sectors within the industry. According to the Intervention & Coiled Tubing Association (ICoTA) in 2018, there were 2040 active coiled tubing rigs in the world. One fourth of all rigs are located in the United States, followed by Canada and then Russia. Coiled tubing is excellent solution for use in ultra deep wells due to depletion of shallow layers and due to the increased utilization of unconventional reservoirs requiring a large horizontal reach and large contact surface between tubing and well. This paper will describe some of the workover and completion operations and provide suggestions of the tool composition for creating high quality bottom hole assembly for proper and successful application.
