Description

Two-channel high efficiency drawing liquid pump

(1) technical field

The utility model relates to oil and extracts equipment, is specifically related to a kind of liquid sorption pump.

(2) background technique

In fact strict, China oil-poor country of real genus.Although the oil recovery facility have tens0000 units in oil pumping round the clock approximately in 11 oil fields, the whole nation, its output of opinion is produced all about the fifty-five million ton half of only enough domestic urgent needs per year.

Country is in order to improve crude output, and will throw tens billion of units and offer Xin Jing every year, Bao Jiujing.Yet it is not remarkable to produce effects, and chasing after its reason has two:

1, since the fifties country establishes the well oil recovery, facility, equipment, technology are prolonged with external imported technology always, and this way of applying mechanically of bringing totally is very far away with the bad adaptability distance of China's physical condition and region.Under the working efficiency;

2, all genus are introduced plant, lack substance and renovate, and will be clear that the machine of establishing (well) oil pumping at this, and what take out is " oil ", and how many annual oil pumping is only the index of weighing working efficiency.

Yet, people in the technological transformation process of decades, always with target lock-on aspect ground pumping unit (being commonly called as the machine of kowtowing) energy-conservation, even microcomputer also moved on the well head, but ignored the other end---oil well pump.The corner that this is forgotten by people but is the key point of taking out (adopting) oil.For example, with micro-processor controlled frequency conversion unit, make each oil pumping stroke power consumption reduce 1/2, about 0.07 yuan energy consumption is saved in corresponding conversion.If focus on the oil well pump, every stroke is taken out one liter of crude oil more, and its economic value is equivalent to 3.75 yuan, and actual effect ratio is 375: 7, and in this case, the effect of oil well pump promotes, and equals to save 54 times power consumption, has reached the effect of getting twice the result with half the effort.And at present countries in the world are ball valve at the oil well pump that prolongs usefulness all, in conjunction with Fig. 1-2, a major diameter steel ball are arranged as main valve in the old-fashioned oil pumping valve pump, and the side clearance of it and valve insertion is as the oil duct of oil-feed.Its shortcoming shows as:

(1) steel ball is very heavy, needs bigger pressure difference (about 0.05Kpa) it could be boosted, so the cracking pressure height, feed liquor is slower.

(2) the oil-feed passage section is too little, only by spheroid and valve pocket side clearance fluid is got in the pump, so resistance is bigger, if oil thicker meeting in source directly influences oil-feed quantity, this also is the major reason that efficient is difficult to improve.

And the present method that does not also have effectively to solve problems such as oil well pump efficient is low.

(3) summary of the invention

The purpose of this utility model is to provide a kind of human oriented design, and it is in light weight to drive valve, closes the valve Heavy Weight, expands side oil channel, increases the two-channel high efficiency drawing liquid pump of guide flow cross section.

The purpose of this utility model is achieved in that it comprises the drawing liquid valve body and is arranged on the interior spool of valve body, the upper end of valve body has liquid outlet, lower end that liquid entering hole is arranged, spool is by the core valve that has central passage and be arranged on that T-valve in the core valve forms, the bottom of T-valve has position-limit mechanism, the feed liquor seat is installed in the liquid entering hole end, and the core valve seat is on the feed liquor seat.

The utility model also has some structure characteristics like this:

1, is provided with guiding trestle in the valve body;

2, guiding trestle is installed in drawing liquid valve body inboard by the guiding grid.

The utility model two-channel high efficiency drawing liquid valve working procedure is:

A, no matter oil well pump rests on any position, and (generally being located at the stroke top dead center) because the core valve hangs by deadweight with " T " valve, closes up two valves naturally, seals oil input channel, makes the core valve form two sections spaces up and down, no pressure difference existence.

B, when the pump housing is descending, liquid sorption pump is in the upper and lower formation pressure difference of core valve.Again because of " T " valve quality very little (just ball valve 1/5), when pressure difference was P 〉=0.002Kpa, " T " valve floated automatically, opens central oil passage, and this moment, passage section was 50% of total flow area, and the core valve is had the traction enhancement effect.

C, when oil well pump continues when descending, core valve both sides pressure reduction constantly increases, when pressure reduction surpassed P 〉=0.04Kpa, the core valve opened, and makes side oil channel open-minded, reaches the bilateral oil duct purpose of conducting together.

D, when liquid sorption pump is up because " T " valve and core valve are subjected to fluid column powerful in the well casing pressure (reaching 12 tons) that recoils, make bivalve fall combination automatically after rise, liquid entering hole is firmly sealed, reach and be strictly on guard against the leakage purpose.

After the utility model product model machine is finished, on probation by the oil field, the respond well design objective that reached.The beneficial effects of the utility model have:

(1) the heavy ball valve of cancellation adopts combined type core valve arrangement, adopts human oriented design, opens valve weight very little (bivalve separations), and bivalve merges the weight amount that strengthens when closing valve, and this has just reached, and to drive valve in light weight, closes the purpose of valve Heavy Weight, and its process is full-automation.

(2) set up central oil passage, expanded side oil channel, make guide flow cross section increase 50%, be former ball valve guide face long-pending 150%.

(3) realized that (P 〉=0.002Kpa) start effect has increased the time and the oil inlet quantity of oil-feed, and has ensured that impact force is little and liquid stream is smooth and easy in minute-pressure.

(4) because be big water conservancy diversion cross section and minute-pressure starting, fluid stream is smooth and easy, no matter to the viscosity size, water content what and whether unfavorable factor such as gassiness all can adapt to, be that current other similar products are irreplaceable.

Adaptability of the present utility model and economic implications have:

1, owing to the unique function of this pump (valve), to the region in oil field, the polytrope of (oil) liquid phase all can adapt to, and no matter is that the home and abroad is suitable for without exception.

2, the utility model designs research and development at the existing tens0000 mouthfuls of oil recovery wells of China, because it has outstanding adaptation to be worth, to such as countries such as Russia, Iran and South Africa market popularization value being arranged also abroad.

3, if its economic value of opinion has the impayable meaning that overflows again.At first, China adopts this product just need not drop into hundred million yuan of funds of hundreds of if improve crude output 20% again at tens0000 mouthfuls of oil wells, just can achieve the goal as long as change one " Twin channel oil pump ".According to measuring and calculating, a two-channel high efficiency oil pump, annual output could improve 3100 tons of crude outputs/platform/year, amounts to 1,000 ten thousand yuan of RMB with one liter of oil accumulative total of every stroke volume increase!

4, from energy-conservation angle estimation, in principle, use the bilateral efficient oil-well pump, do not increase the consumption of any electric power, it is estimated, the every stroke oil pumping of pumping unit (mentioning) weight is 12 tons, if increase the lifting weight (just approximate a kilogram) of one liter of oil.It and 12 tons (12000 kilograms) are in a ratio of 12000: 1, can ignore fully.

Yet the economic value that it is created is ten million yuan! An equal anything but rank and discussing! Nearly 10,000 times of its energy-saving effect!

5, this product self-value estimation, at first, the human dependence of crude oil is saved your breath also taken 30-50, estimate and do not talk new energy and whether cashed in a short time, and human clothing, the food of reality, live, the also too busy to get away oil of row.The market of the utility model product far away from the world, is the product of " tree green for a long time " formula closely at home, has quite powerful vitality.
