Description
Technical field
The present invention be a kind ofly integrate anticorrosion, antiscale, wax control, anti-thickness, gas-tight, sand control organic six anti-without bar hydraulic drive double action for reciprocating pump, belong to mechanical oil recovery technology frontier.
Background technique
In the rod pump mechanical oil recovery of oil field, adopt inorganic steel oil well pump bar none.Due to the geological condition of oil reservoir complexity and the difference of crude oil property, sand, wax, thick, dirty, gas and high salinity aggressive medium drastically influence the working life of inorganic-steel rod pump.Round anticorrosion, antiscale, wax control, anti-thickness, gas-tight, a sand control difficult problem, oil production technology technician exhausts effort, develops numerous advanced practical new technology, new process.Large quantities of wax control, sand control, degasification, the anti-corrosive apparatus such as chemical consolidated sand, Swirling flow sand-removing, efficient filter sand, mechanical wax removal, paraffin control with inhibitor viscosity reduction, strong magnetic paraffin control viscosity reduction, high efficient gas anchor, coating for protection against corrosion are applied to oil extraction in oil field technique, define covering extensive fields, interdisciplinary, across work post note, adopt, communication system, support the development of petroleum industry.
Though above-mentioned technology and technique extend the working life of inorganic-steel rod pump to a certain extent, be difficult to fundamentally stop above-mentioned harm, pump rate of fault is high, and pump detection period is short, and cost for oil production remains high, and becomes restriction oil production technology and attacks a difficult problem of being unable to for a long time.
Over nearly 10 years, in order to realize efficient, the low consumption of oil production technology, and solving at one stroke the puzzlement of sand, wax, thick, gas and corrosion and scaling, domesticly having risen research without bar Hydraulic pump and upsurge of tackling key problems, and obtained nearly 100 patent achievements.The high quality power fluid that technician attempts to provide temperature higher by ground liquid supply station drives the acting of underground reciprocating pump, realizes achieving many things at one stroke.
One is economize on electricity consumption reduction, realizes low energy consumption and recovers the oil;
Two is solve wax-proof viscosity reducing problem by the power fluid that temperature is higher;
Three is cancel pumping unit, sucker rod, saves construction investment;
Four is simplify to optimize ground flow, reduces maintenance workload.
Above-mentioned achievement in research will promote oil recovery technique progress theoretically, but also bring certain negative effect thereupon.
Though one is the quality problems that ground central fluid supply solves power fluid, virtually increase construction investment and management difficulty;
Two is that individual well dispersion feed flow convenient operation runs, but the loss of power fluid causes again unnecessary trouble with supplementing;
Three is that reliability and the life-span of selector valve have a greatly reduced quality regardless of ground or underground hydraulic commutation.
Therefore, although theory and patent achievement obtain encouraging success, over 10 years, still do not have a patented technology successfully to apply to mining site practice.
How to realize a pump multi-functional, slow down or stop the harm of sand, wax, thick, dirty, gas and aggressive medium, improve oil field development benefit further, become urgently to be resolved hurrily and problem that is that capture.
Explore and often only have one step away from success, analyse in depth the reason that numerous patented technology is difficult to be converted into productivity, not patent achievement technology content problem, but research process does not break away from the constraint of the law of inertia, there is inertial thinking blind area in Research Thinking, the shortcut often broken through just but can not find the essential crux of technical solution problem at one's side.Such as to solve anticorrosion, the scale problems of downhole pump, people get used to studying expensive stainless steel or the non-ferrous metal coating of high pollution, and do not remove to develop the organic plastics of the difficult fouling of not burn into, wax control, anti-thick excellent, it is the scheme proposing organic plastics, also 100 question marks are made a call to unused query, cause many high-performance organic plastics goods with satellite heaven, but have no so far and pump into missile silo with oil pumping; For another example to improve the workpiece life-span of frequent wear working condition continuously, often disregard the alloyed steel of the preferred superhard wear of cost and overcritical machining accuracy, but have ignored and do not wear and tear or the technological approaches of less wear.Thus, successful tricks of the trade need break traditions inertial thinking dead angle, look for another way, act in a diametrically opposite way, just can receive the special effect of getting twice the result with half the effort!
Summary of the invention
For the corrosion that inorganic-steel sucker rod pumping faces, fouling and sand, wax, thick, gas endangers, the object of the invention is the inertial thinking that breaks traditions, exploration high strength, high temperature resistant, anti-aging, corrosion-resistant, inadhesive organic material component replaces inorganic steel component, and to the sealing means of general rod pump and the commutating structure of commercially available two-position four-way valve and avoid to greatest extent wearing and tearing link and the time of reducing wear carry out breakthrough innovation, sand control is set dexterously simultaneously, depassing unit, a kind of collection of design is anticorrosion, antiscale, wax control, anti-thickness, gas-tight, sand control is anti-without bar hydraulic drive double action for reciprocating pump in integrally organic six, the directivity realizing oil extraction in oil field technique updates.
