Abstract
The utility model discloses an oil production device capable of overcoming gas locking of a gas contained oil well, which is characterized in that a sieve tube (4) is directly fixedly connected with the bottom portion of an oil-well pump (3), wherein a tail pipe (5) is also fixedly connected with the bottom portion of the sieve tube (4), the bottom portion of the oil-well pump also can be fixedly connected with an oil-gas separator (9), and the tail pipe is also fixedly connected with the bottom portion of the oil-gas separator (9). Because the oil production device completely puts off a middle pipe in an existing oil production device, a space which can generate air locking does not exist between the oil-well pump and the sieve pipe or the oil-gas separator, the oil-well pump directly sucks oil liquid, the phenomenon of air locking does not appear, thereby being capable of increasing yield, oil production efficiency and economic benefit. Simultaneously, the oil production device overcomes the phenomenon of air locking, guarantees the oil-well pump not to be milled in the air, prolongs the service life of the oil-well pump, and also avoids economic losses which is brought because of maintenance and replacement of the oil-well pump.
Description
Technical field
The utility model relates to a kind of extracting device of oil that overcomes gassiness oil well gas lock.
Background technique
In the oil well in a lot of oil fields; tend to be connected the long intervalve (also claiming extension tube) of tens meters even hundreds of rice and cathodic protector etc. between oil well pump and the screen casing; oil level in the distance between oil well pump and the screen casing (referring to Fig. 3) too far away, well bucket is higher than screen casing far away.After oil and gas constantly enter intervalve in the hole of screen casing simultaneously, the pressure of gas will be increasing in the intervalve, form gas chamber effect (also claiming gas lock), gas has occupied the position of fluid in intervalve, make fluid can not normally enter oil well pump, this gas lock phenomenon is having a strong impact on the pumping action of oil well pump to fluid, can directly cause the reduction of oil recovery efficiency and output.In addition, empty mill phenomenon will appear in oil well pump when fluid advances less than oil well pump, is easy to make oil well pump to damage, and needs often oil well pump to be repaired or replaced, and has both influenced ordinary production, can cause bigger economic loss again.For a long time, this mode of structure is applied in a lot of extracting device of oil always, so directly have influence on oil recovery efficiency and economic benefit to a great extent.
Summary of the invention
The technical problems to be solved in the utility model is exactly for overcoming the deficiencies in the prior art, provides a kind of and can overcome the gas lock phenomenon, can prevent the empty mill of oil well pump, improves the extracting device of oil of the overcome gassiness oil well gas lock of oil recovery efficiency.
Technical solution of the present utility model is:
This extracting device of oil comprises oil pick-up tube and oil well pump, and it mainly is that screen casing is directly fixedlyed connected with the oil well pump bottom, and tail pipe is fixedlyed connected with the screen casing bottom again.
Further technical solution of the present utility model is:
Oil well pump bottom also can a fixedly connected gas and oil separating plant, and tail pipe is fixedlyed connected with the gas and oil separating plant bottom again.
Oil well pump is threaded with oil pick-up tube.
Gas and oil separating plant is connected with oil pump thread.
Description of drawings
Fig. 1 is the structural representation that screen casing directly is connected with the oil well pump bottom in the utility model.
Fig. 2 is the structural representation that gas anchor directly is connected with the oil well pump bottom in the utility model.
Fig. 3 is the structural representation that is connected intervalve in the prior art between oil well pump and the screen casing.
Embodiment
Embodiment 1:
As shown in Figure 1, be arranged in and connect an oil well pump 3 that has a sucker rod 1 on the oil pick-up tube 2 of oil well, the screen casing 4 that has oil inlet hole directly is connected with the bottom thread of oil well pump 3, and the tail pipe 5 that has plug 6 is connected with screen casing 4 bottom thread again.This mode of structure should be with the bottom of oil well pump 3 a little more than oil level 7, and oil level 7 is a little more than the oil inlet hole of screen casing 4.
This mode of structure is owing to without intervalve screen casing 4 directly being connected with oil well pump 3 fully, oil well pump 3 directly acts on fluid, the space of gas lock does not appear producing between the two, most gases contained in the fluid can be overflowed from oil level 7, the small part of gas that only has little time to overflow enters oil well pump 3 with fluid, but can not form the gas lock phenomenon, can not cause any adverse effect yet output and oil well pump 3.
Embodiment 2:
As shown in Figure 2, a gas and oil separating plant 9 (being commonly called as gas anchor) also can directly be threaded in oil well pump 3 bottoms that have sucker rod 1, but should make oil level 7 just surpass filler opening 8 lower edges of gas and oil separating plant 9, the bottom of gas and oil separating plant 9 connects a tail pipe 5 that has a plug 6 again.
" a kind of efficient gas anchor " (patent No.: 200720031813.2) directly be connected oil well pump 3 bottoms of the utility model power of the applicant once can being patented, can obtain oil gas separation preferably, so that reach the purpose that increases substantially oil recovery efficiency.
Can make oil after the fluid that contains gas enters gas and oil separating plant 9 by filler opening 8, be so incensed that good separation, it is whole that oil well pump 3 is extracted into is fluid, can not produce the gas lock phenomenon.
By above technical solution and embodiment as can be seen, the utility model is owing to the intervalve that has removed fully in the existing extracting device of oil, make and do not have the space that can produce gas lock between oil well pump and screen casing or the gas and oil separating plant, oil well pump directly aspirates fluid, there is not the gas lock phenomenon to occur, so can improve output and oil recovery efficiency and economic benefit.Simultaneously, overcome the gas lock phenomenon and just can guarantee that oil well pump can empty not grind, prolonged the working life of oil well pump, also avoided owing to the maintenance of oil well pump, the economic loss that replacing brings.The utility model is being obtained good effect after the test on the many mouthfuls of oil wells, and oil output is increased dramatically.
