Abstract
The invention provides a small hole well completion lifting technology tubular column and a use method of the small hole well completion lifting technology tubular column, and solves the problems that an existing lifting tubular column in an oil field is inconvenient to lift and locate in the using process, and the like. The small hole well completion lifting technology tubular column comprises a hollow oil rod, a rod pump, an anchor and a lifting operating barrel, wherein the lifting operating barrel is provided with a mechanism which is matched with an anchoring mechanism of the anchor. At the time of well completion, firstly, the lifting operating barrel is placed downwardly to the position, corresponding to the depth where the rod pump is to be hung, of a casing pipe, then a connected combination of the hollow oil rod, the rod pump and the anchor is placed downwardly, and the anchoring mechanism of the anchor and the corresponding and matching mechanism on the lifting operating barrel are used for accurate location. At the time of an overhaul, the hollow oil rod is lifted upwardly to enable the anchoring mechanism to break away from the lifting operating barrel, and then the rod pump can be taken out. The small hole well completion lifting technology tubular column has the advantages of being simple in structure, easy to control, convenient to overhaul and operate and the like, and is mainly used for an oil well with a small hole.
