Abstract
The utility model discloses a wear-resistant connector of a non-magnetic drilling tool. The wear-resistant connector of the non-magnetic drilling tool comprises a body and a non-magnetic pressure-bearing drill pipe, wherein the wear-resistant connector is arranged on the body, is a hollow pipe pillar and is welded to the non-magnetic drilling tool, tail end truncation threads are arranged on the wear-resistant connector, the wear-resistant connector is arranged at the upper end of the non-magnetic pressure-bearing drill pipe, the outer diameter of the wear-resistant connector is 3 mm larger than the inner diameter of the non-magnetic pressure-bearing drill pipe, and a wear-resistant belt and a GMC buckle are further arranged at the lateral end of the wear-resistant connector. The wear-resistant connector of the non-magnetic drilling tool is simple in structure, is easy to operate, improves working time efficiency, and plays a positive role in protecting the non-magnetic drilling tool and saving a large amount of non-magnetic drilling tool purchase capital.
Description
Technical field
The utility model relates to the servicing unit that a kind of oil field is used, the particularly wear-resistant joint of a kind of non-magnetic drilling tool.
Background technology
The non-magnetic drilling tool using at lower curved section in drilling process, under Action of Gravity Field, produce eccentric wear with the borehole wall, because joint diameter is greater than pipe diameter, be on active service in long-time down-hole, joint area produces eccentric wear phenomenon, will wear away soon, attenuating or eccentric wear appears in joint external diameter too early, causes scrapping without magnetic pressure-bearing drilling rod or drill collar.Because non-magnetic drilling tool is expensive, buying needs cost to purchase in a large number fund.For the fine-grained management of active response oil field; realize the requirement of cost efficiency; this achievement is target from protection at well non-magnetic drilling tool, develops and apply the wear-resistant joint of novel non-magnetic drilling tool, protecting non-magnetic drilling tool, save a large amount of non-magnetic drilling tools and purchase fund and played positive impetus.
Summary of the invention
The technical problem that the utility model solves is to provide the wear-resistant joint of a kind of non-magnetic drilling tool, simple in structure, and easy operating has improved security performance and work limitation.
The wear-resistant joint of a kind of non-magnetic drilling tool, comprise body and non-magnetic drilling tool, it is characterized in that: the wear-resistant joint of a kind of non-magnetic drilling tool, comprise body and without magnetic pressure-bearing drilling rod, described body is provided with wear-resistant joint, the tubing string that described wear-resistant joint is hollow is also welded on non-magnetic drilling tool, described wear-resistant joint is provided with end and scabbles screw thread, described wear-resistant joint is arranged on the upper end without magnetic pressure-bearing drilling rod, the external diameter of described wear-resistant joint is than the large 3mm of internal diameter without magnetic pressure-bearing drilling rod, and the side of described wear-resistant joint is also provided with wear-resistant strip and GMC button.
The beneficial effects of the utility model are:
Adopt the wear-resistant joint of a kind of non-magnetic drilling tool of the utility model, simple in structure, easy operating, has improved work limitation, at protection non-magnetic drilling tool, save a large amount of non-magnetic drilling tools and purchase fund and played positive impetus.
