Abstract

The utility model belongs to the technical field of mechanical oil extraction process in oil exploration, which relates to a newly-developed oil pumping rod weight increaser, which can be mutually connected to avoid falling off and reducing the weight increasing cost when the oil pumping rod is broken. The utility model mainly consists of a block1, an outer join2, a weight increaser body internal lining3, a weight increaser body outer pipe4, a reinforcing steel bar5 and an inner joint6. The utility model is mainly used for the oil pumping machine well, which has the advantages of quick and convenient mounting and easy processing.

Description

The sucker rod emhasizer

Technical field: the utility model belongs to mechanical oil production technology technical field in the oil development.

Background technology: existing sucker rod increases the weight of to have two kinds, a kind of is with the sucker rod overstriking, increase the weight of rod string, but this technology has a problem, the weight of every weighted lever is evenly to be added on the rod string exactly, make the bottom of whole roofbolt in down stroke, still be in pressured state, can not solve the pressurized problem of rod string fully.Second kind is ring-like weight-adding hammer, can reach the purpose that increases the weight of.Promptly add weight and can make sucker rod all be in tension state, but that it increases the weight of cost is too high, and do not connect between two weight-adding hammers.Just in case R a T is disconnected simultaneously, brings difficulty to salvaging.

Summary of the invention: the purpose of this utility model is newly developed between a kind of sucker rod emhasizer and can be connected to each other, and avoids coming off when sucker rod is disconnected and reducing the sucker rod emhasizer that increases the weight of cost.

The sucker rod emhasizer mainly is made up of block, socket, emhasizer body liner, emhasizer body outer tube, reinforcing bar, spigot.

Wherein the block of sucker rod emhasizer is welded in the external surface of socket, clip reinforcing bar between emhasizer body liner and the emhasizer body outer tube, emhasizer body liner, emhasizer body outer tube, reinforcing bar are formed the emhasizer body together, emhasizer body upper end welds together with socket, and the lower end and the spigot of emhasizer body weld together.Have a groove on the utility model outer wall, the groove width is identical with the sucker rod diameter, is convenient to the utility model and is enclosed within on the sucker rod.Have a vertical slot on the spigot inner hole wall, have a cannelure on the spigot inner hole wall simultaneously, the cannelure two ends are dead with the block weldering.

Compared with the prior art the utility model has following advantage:

The utility model convenience quick for installation, cost is low, is easy to processing.All sucker rod emhasizers are linked together simultaneously, and whole weight acts on the plunger, have solved roofbolt down stroke pressurized problem, reduce the wearing and tearing between sucker rod and the oil pipe.

Description of drawings: Fig. 1 is the utility model structure diagram;

Fig. 2 is the sectional drawing of top connection 2;

Fig. 3 is the sectional drawing of emhasizer body;

Fig. 4 is the sectional drawing of spigot 6.

The specific embodiment: the sucker rod emhasizer mainly is made up of block 1, socket 2, emhasizer body liner 3, emhasizer body outer tube 4, reinforcing bar 5, spigot 6.

Wherein the block 1 of sucker rod emhasizer is welded in the external surface of socket 2, clip reinforcing bar 5 between emhasizer body liner 3 and the emhasizer body outer tube 4, emhasizer body liner 3, emhasizer body outer tube 4, reinforcing bar 5 are formed the emhasizer body together, emhasizer body upper end welds together with socket 2, and the lower end of emhasizer body and spigot 6 weld together.Have a groove on the utility model outer wall, the groove width is identical with the sucker rod diameter, is convenient to the utility model and is enclosed within on the sucker rod.Have a vertical slot on spigot 6 inner hole walls, have a cannelure on spigot 6 inner hole walls simultaneously, the cannelure two ends are dead with block 1 weldering.

On-the-spot when using the utility model, when lower sucker rod, be enclosed within and go into the well with sucker rod on the sucker rod.When first sucker rod and plunger join good after, with first sucker rod emhasizer socket 2 up, spigot 6 is through on the sucker rod by the groove on its outer wall down, and seat is in the plunger upper end, with second sucker rod emhasizer socket 2 up, spigot 6 is through on the sucker rod by its groove down.Simultaneously, the inner hole wall vertical slot of the block 1 in the socket 2 of first sucker rod emhasizer from second sucker rod emhasizer spigot 6 inserted, Rotate 180 degree then, such two sucker rod emhasizers just are linked together firmly and are enclosed within on the sucker rod.According to above operating procedure, according to the weight that increases the weight of the sucker rod emhasizer of some is installed, be used for the rod-pumped well oil pumping.
