Abstract

The utility model relates to a steel wire rope for pumping oil, which is formed by that multiple strands of wire contact round strand steel-cored steel wire ropes clamped with steel cores are compacted, wherein, each stand of the steel wire rope and each steel wire in each stand of the steel wire rope are all deformed; the tangential abutted surface of the outwardly exposed surface of each steel wire at the outer layer of each stand of the steel wire rope and the outer surface of the whole steel wire rope becomes larger; the tangential abutted surface between each two steel wires becomes larger; but a gap between each two steel wires becomes smaller; so, a relatively smooth and wear-resistant surface is formed. The utility model has the advantages of high rigidity, high elastic modulus, favorable shock resistant performance, good wear-resistant performance and good structural stability.

Description

The oil swabbing and taking wire rope

The utility model relates to petroleum industry oil well oil swabbing and taking operation wire rope.

Oil field operation adopts dredging vehicle (also claiming pumping car or oil pumping vehicle) more and more, and wire rope is its important accessory.During operation (referring to Fig. 1), an end of wire rope 5 is fixed on the reel 2 of operating vehicle 1, through being lowered to oil well 6 behind guide wheel 3 and the top sliding 4, the other end of wire rope with drag for oily instrument and link to each other, by mentioning fast and transferring the purpose that reaches oil swabbing and taking.The oil swabbing and taking operation is big at load, carries out under the big condition of impulsive load, requires wire rope to have higher rigidity, takes out dark big, characteristics such as stroke is long.Oil swabbing and taking operation wire rope of the prior art, its structure generally is 6 * 19S+FC round-strand rope, the wire rope of this structure, because anti-radial force scarce capacity, fiber wire rope core crushing resistance is poor, and structure stability is bad, can not satisfy the requirement of oil swabbing and taking operation, it is big usually to occur elongation in operation process, structural damage phenomenons such as (conquassation) causes wire rope just to be scrapped after short-term is used, and has increased operating cost, even cause down-hole accident, cause very big loss.

The purpose of this utility model provides the oil swabbing and taking wire rope that a kind of rigidity is big, Young's modulus is high, impact resistance is good, wear-resisting property is good, structure stability is good, to improve the efficient of dredging vehicle oil producing operation, reduce production costs, and the generation of minimizing accident.

The technical solution of the utility model is: a kind of oil swabbing and taking wire rope, be characterized in: form by a multiplied yarn contact circle strand independent wire strand, this multistrand rope is after compacting, per share wire rope wherein and every steel wire in the per share wire rope all are out of shape, the tangent abutted surface that every steel wire of per share wire rope ectomesoderm is exposed to the outer surface of outer surface and whole wire rope becomes big, tangent abutted surface between steel wire and the steel wire becomes big, and steel wire and gaps between steel wires diminish, thereby have formed an opposed flattened and wear-resisting surface.

According to above-described oil swabbing and taking wire rope, be characterized in: this wire rope is made up of a multiplied yarn contact circle strand independent wire strand folder steel core.

According to above-described oil swabbing and taking wire rope, be characterized in: this wire rope is made up of a three fold yarn contact circle strand independent wire strand.

According to above-described oil swabbing and taking wire rope, be characterized in: this wire rope is made up of four a strands contact circle strand independent wire strand folder steel core.

According to above-described oil swabbing and taking wire rope, be characterized in: this wire rope is made up of six a strands contact circle strand independent wire strand folder steel core.

When being the oil swabbing and taking operation, uses Fig. 1 the schematic representation of wire rope.

Fig. 2 is three bursts of compacting wire rope cross sectional representation.

Fig. 3 is a multiply steel core compacting wire rope cross sectional representation.

Among the figure: 1-operating vehicle; The 2-rolling wheel; The 3-guide wheel; 4-pushes up sliding; The 5-wire rope; The 6-oil well; The 7-steel wire; 8-steel wire outer surface; 9-wire rope outer surface; The tangent abutted surface of 10-steel wire outer surface and wire rope outer surface; Tangent abutted surface between 11-steel wire and the steel wire; 12-steel wire and gaps between steel wires; The 13-steel core.

Below in conjunction with accompanying drawing the technical solution of the utility model is further described:

A kind of oil swabbing and taking wire rope (referring to Fig. 2 and Fig. 3), form by a multiplied yarn contact circle strand independent wire strand, this multistrand rope is after compacting, per share wire rope wherein and the every steel wire 7 in the per share wire rope all are out of shape, it is big with tangent abutted surface 10 changes of the outer surface 9 of whole wire rope that the every steel wire 7 of per share wire rope ectomesoderm is exposed to outer surface 8, tangent abutted surface 11 between steel wire 7 and the steel wire 7 becomes big, and the space 12 between steel wire 7 and the steel wire 7 diminishes, thereby has formed an opposed flattened and wear-resisting surface.

Above-described wire rope can be made up of a three fold yarn contact circle strand independent wire strand, as 3 * 19S.(referring to Fig. 2)

Above-described wire rope can be made up of four a strands contact circle strand independent wire strand folder steel core 13, as 4 * 19S+IWRC.

Above-described wire rope can be made up of six a strands contact circle strand independent wire strand folder steel core 13, as 6 * 26WS+IWRC.(referring to Fig. 3)

In implementation process of the present utility model, Shandong formula line touch interaction is twisted with the fingers a circle strand independent wire strand folder steel core and obtain novel wire rope behind overcompaction (die forging or extruding) to the west of us.By test, find that this wire rope has the following advantages:

1. this wire rope is owing to adopted compaction process, and the metal section modulus has improved 8-13%, and Young's modulus improves, under the condition of rupture pull force, wire rope rope footpath can reduce, and the length held in operating vehicle increases, like this, can satisfy the requirement of deep-well oil swabbing and taking operation.

2. compacting wire rope rigidity is big than the rigidity of the round-strand rope of 6 * 19S+FC structure, and impact resistance is good, and structure stability is good.

3. compacting wire rope wear-resisting property is good, because compacting changes surface state, wear-resisting property improves more than 2 times, can reach average life more than 500 times, and the life-span of existing wire rope is 200-280 time.

4. utilization of the present utility model has improved the efficient of dredging vehicle oil producing operation, has reduced cost of production, has reduced the generation of accident.
