Abstract
Opremanje geotermalnih bušotina obavlja se na jednak način kao i opremanje HPHT naftnih i plinskih bušotina. Međutim, proces bušenja i cementacije uvelike se razlikuje jer su uvjeti za dizajn isplake i cementne kaše koje su namijenjene za primjenu u geotermalnim bušotinama zahtjevniji od njihova dizajna za naftne i plinske bušotine. Problemi koji se posebno izraženi u geotermalnim bušotinama su: diferencijalni prihvat uslijed stvaranja debelog isplačnog obloga, gubljenje cirkulacije, CO2 korozija kolone zaštitnih cijevi i cementnog kamena i visoke temperature. Dizajn cementne kaše i njenih svojstava, kao i postupak cementacije mora se planirati i provesti uzimajući u obzir sve prethodno navedene probleme. U ovom radu opisano je cementiranje geotermalnih bušotina i prikazane su specifičnosti dizajna cementne kaše za geotermalne bušotine u odnosu na HPHT naftne i plinske bušotine. Na kraju rada prikazani su primjeri iz prakse cementacije zaštitnih cijevi u geotermalnim bušotinama i problemi koji su se javili prilikom cementacije.
Abstract (english)
Geothermal well completion is performed in the same way as the completion of HPHT wells. However, the process of drilling and cementation is very different because the conditions faced by the cement slurry and rocks at geothermal wells are extremely demanding. Geothermal wells are frequently faced with numerous problems, such as mud cake, circulation loss, the threat of corrosion caused by carbon dioxide and high temperature. Cement slurry design and its features, as well as the process of cementation has to be planned in detail, taking into consideration all the problems that might be encountered. This thesis describes the cementation of a geothermal well as well as the specifics of cement slurry design for geothermal wells with regards to HPHT oil and gas wells. The thesis also provides some practical examples of the process of casing cementation in geothermal wells and gives an overview of problems which occurred during cementation.
