Návrh konstrukce a vystrojení sond pro geosekvestraci CO2 v kolektorských vrstvách.

Abstract

Capture and storage of carbon dioxide (CCS - Carbon Capture and Storage) is considered one of the possible ways at least in part to reduce CO2 emissions from human activities and still benefit from this activity, secondary gain in the form of eg. increase the yield of some oil fields. The aim of this study is to evaluate the current state of knowledge of this problem, which includes technical, scientific, environmental and social dimensions of storage and engineer the equipping well for CO2 injection. One of the objectives of the dissertation is to describe the actual process geosequestration CO2 and evaluate possible options in the Czech Republic. It seems that the only real option for relatively Czech Republic is the injection of carbon dioxide into hydrocarbon deposits, while at ended of oil deposits use effect of an increase in daily production. Therefore, one part of the dissertation briefly focused on the behavior of CO2 in interaction with the oil in the immediate vicinity of the injection probe. The main aim of the dissertation is to design the construction and equipping injection well. It is clear that CO2 will have a corrosive effect on all equipping well, so that part is devoted to research on the influence of carbon dioxide on the casing, footrests and packers and further cementing the quality of interaction and CO2 at the rock x cement x casing. The work also includes evaluation of the current state of equipping wells designed for the extraction of hydrocarbons is currently a proposal new egipment possible so that the well could become an injection wells. This part is followed by a proposal to drilling and equipping a completely new well intended only for CO2 injection.
