Abstract
The utility model relates to oil production equipment, in particular to a downhole oil production device with a non-metallic sucker rod. The downhole oil production device is mainly composed of the non-metallic sucker rod, a connector, a steel sucker rod and a downhole pump, wherein the two ends of the connector are respectively connected with the non-metallic sucker rod and the steel sucker rod; an oil pumping unit device on the ground directly drives the non-metallic sucker rod through a beam hanger, the non-metallic sucker rod reciprocates in the oil pipe with an inner protective material layer, and the steel sucker rod reciprocates in a pump cylinder. The downhole oil production device has the benefits that the different combination of the non-metallic sucker rod and the steel sucker rod realizes oil production in the oil pipe with the inner protective material layer, so that the defects that the common steel sucker rod is easily corroded, the side face is seriously damaged and the like are overcome, the defects that the non-metallic sucker rod in the ordinary oil pipe is easily abraded, the non-metallic sucker rod loses efficacy too early and the like are overcome, the service life of the oil pipe is prolonged, and the working cycle is shortened.
Description
Technical field
The utility model relates to a kind of oil exploitation equipment, particularly a kind of nonmetal sucker rod downhole oil extraction device.
Background technology
In the exploitation of oil middle and later periods, pumping rod made by steel, tube inner wall seriously corroded, and pumping rod made by steel and tube inner wall friction cause the side well damage.Though and nonmetal sucker rod is corrosion-resistant, the body of rod is easy to wear in oil pipe inside, loses efficacy very soon after the wearing and tearing, influences the overall operation life-span.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art; A kind of nonmetal sucker rod downhole oil extraction device is provided; Shortcomings such as common pumping rod made by steel is not corrosion-resistant, side well damage had both been solved; Solved again that nonmetal sucker rod is easy to wear in oil pipe inside, the premature failure shortcoming, and prolonged the oil pipe life-span, shortened duty cycle.
Its technical scheme is: mainly be made up of nonmetal sucker rod, connector, pumping rod made by steel, down-hole pump, the two ends of described connector connect nonmetal sucker rod and pumping rod made by steel respectively; Pumping unit apparatus directly drives nonmetal sucker rod through polished rod eye on the ground, moves reciprocatingly in the oil pipe of nonmetal sucker rod layer of protective material in having, and pumping rod made by steel moves reciprocatingly in pump barrel.
Wherein, the interior layer of protective material that is provided with in the oil pipe is the non-metallic material bed of material or wear-and corrosion-resistant coating.
The beneficial effect of the utility model is: realize in the oil pipe of the various combination of nonmetal sucker rod and pumping rod made by steel layer of protective material in having recovering the oil; Shortcomings such as common pumping rod made by steel is perishable, side well damage had both been solved; Shortcomings such as nonmetal sucker rod is easy to wear in plain tubing inside, premature failure have been solved again; And prolonged the oil pipe life-span, shortened duty cycle.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: nonmetal sucker rod 1, connector 2, pumping rod made by steel 3, oil pipe 4, down-hole pump 5.
The specific embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of nonmetal sucker rod 1, connector 2, pumping rod made by steel 3, down-hole pump 5, and the two ends of described connector 2 connect nonmetal sucker rod 1 and pumping rod made by steel 3 respectively; Pumping unit apparatus directly drives nonmetal sucker rod 1 through polished rod eye on the ground; Move reciprocatingly in the oil pipe 4 of nonmetal sucker rod 1 layer of protective material in having; Wherein, the interior layer of protective material that is provided with in the oil pipe 4 is that the non-metallic material bed of material or wear-and corrosion-resistant coating are processed; Pumping rod made by steel 3 moves reciprocatingly in pump barrel, thereby realizes the purpose of oil recovery.
