Abstract
Due to the limitation of the working dip angle of conventional oil pump and the problems about the eccentric wear of sucker rods and oil tube, oil pumps can only be placed in vertical section to produce oil in most horizontal well, which can not satisfy the demands of deep pumping and reducing flow pressures. Therefore, through the analysis of adaptability of the lifting technology for horizontal wells, the deep pumping engineering technology which is suitable for the lifting in kick-off section of horizontal wells has been investigated and formed, such as inclined well pumps, the matching anti-eccentric wearing and centralizing technology for sucker rod and oil tube and the oil tube anchoring technology. The field test indicates that the inclined well pump shows normal operation at the well section with the dip angle of 60° , and the matching technology of the deep pumping for horizontal wells is created, which satisfies the demands of deep pumping at the near-horizontal section of horizontal wells. Therefore, an obvious stimulation effect is obtained, and there is a relatively good application prospect.关键词
