一口油井钻凿成功后,经过测试评价认为经济上合算就要作完井处理。完井的目的是巩固井壁,建立一条畅道的油流通道。根据油层条件及采油工艺要求,有多种完井方式。例如:裸眼完井、套管射孔完井、裸眼封隔完井、绕丝筛管完井、割缝衬管完井、裸眼(或管内)预克填完井、裸眼(或管内)井下砾石充填完井,以及平行多油管完井等等。浅层稠油油井,大多采用水泥国井后套管射孔完井。对一口用法蒸汽井采稠油的浅层稠油油井,除采用通常的完井技术外,还有几项特殊要求。
After an oil well was successfully drilled, after testing and evaluation that is economically cost-effective will be for well completion. Completion of the goal is to consolidate the shaft wall, the establishment of a smooth oil flow channel. Depending on reservoir conditions and oil recovery requirements, there are a number of well completion methods. Examples include open-hole completion, casing perforation completion, open-hole confinement completion, wire-wound screen completion, slotted liner completion, openhole (or in-pipe) Gravel pack completions, parallel multi-well completions and more. Shallow thick oil wells, most of the wells after the cement casing perforation completion. In addition to the usual well completion techniques, there are a few special requirements for a shallow heavy oil well that uses heavy oil for a steam well.
