Abstract
The utility model relates to a thermal production steam injecting string drop collector for a thermal production well of petroleum industry, which is arranged on the lower part of a steam injecting string of the thermal production well to collect dirt and impurities generated in the steam injecting process and ensure the steam injecting effect. The collector comprises a connecting mechanism and a drop collecting mechanism, wherein the drop collecting mechanism is hung in the connecting mechanism. The collector is connected with the lower part of the steam injecting string through the connecting mechanism, and the dirt generated in the steam injecting process is collected by the drop collecting mechanism. The dirt block generated in the steam injecting process is collected into a dirt settling pipe, so the dirt block cannot block the steam injecting string or the oil layer, and the thermal production well is ensured to normally inject steam and produce petroleum. When used for the thermal production and steam injection of the horizontal well, the utility model effectively prevents the blockage of the distributing and injecting device at the bottom of the steam injecting string caused by the iron rust and dirt on the inner wall of the heat isolation pipe falling into the well, thereby ensuring the uniformity of the steam injection of the ground layer, and obviously enhancing the steam injecting effect.
Description
Technical field
The utility model belongs to the down-hole oil production equipment of petroleum industry, and thermal recovery steam injection string junk gatherer particularly is used for the bottom of thermal production well steam injection string, collects the dirt and the impurity that produce in the steam injection process, guarantees to annotate the vapour effect.
Background technology
Be lowered to the thermal recovery steam injection string in the thermal production well well, can produce a lot of dirts in steam injection process, these dirty pieces can together be injected in the oil reservoir with steam, cause oil layer blocking to annotate not admission, and the vapour effect is annotated in influence.Particularly when vapour is annotated in costly horizontal well thermal recovery, the iron rust of instlated tubular inwall, the dirt well that falls causes the obstruction of steam injection string bottom injection allocation device easily, thereby can influence the uniformity coefficient that vapour is annotated on the stratum, even causes annotating the failure of vapour engineering.The generation of the problems referred to above all can bring great economic loss, and the production scene needs a kind of instrument to address the above problem.
Summary of the invention
The purpose of this utility model provides thermal recovery steam injection string junk gatherer, solves the collection problem of dirt in the thermal production well steam injection string, prevents to stop up steam injection string and oil reservoir, guarantees to annotate carrying out smoothly of vapour engineering, increases economic efficiency.
The purpose of this utility model is achieved in that thermal recovery steam injection string junk gatherer comprises bindiny mechanism and junk collecting mechanism, hangs on the junk collecting mechanism in the bindiny mechanism.This instrument is collected the dirt that produces in the steam injection process by the bottom that bindiny mechanism is connected in the thermal production well steam injection string by the junk collecting mechanism.
The beneficial effects of the utility model are: this tool construction is simple, and is easy for installation.Be connected in the bottom of steam injection string, the dirty piece that produces in the steam injection process can be collected in the sediment-precipitating pipe, dirty piece can not stop up steam injection string or oil reservoir, and the vapour well is annotated in the assurance thermal recovery can normally annotate vapour, oil recovery.When particularly being applied to horizontal well thermal recovery notes vapour, iron rust, the dirt that can effectively prevent the instlated tubular inwall well that falls causes the obstruction of steam injection string bottom injection allocation device, thereby can guarantee that the stratum annotates the uniformity coefficient of vapour, obviously improve and annotate the vapour effect, have remarkable economic efficiency.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further: referring to accompanying drawing, thermal recovery steam injection string junk gatherer comprises bindiny mechanism and junk collecting mechanism, and the junk collecting mechanism is hung in the bindiny mechanism.This instrument is collected the dirt that produces in the steam injection process by the bottom that bindiny mechanism is connected in the thermal production well steam injection string.The junk collector mechanism comprises suspension joint 2, sediment-precipitating pipe 3 and plug 5, suspension joint 2 is connected with sediment-precipitating pipe 3, and the bottom of sediment-precipitating pipe 3 connects plug 5, and tube wall is provided with connected entrance 6 on the top of sediment-precipitating pipe 3, be heavy dirty chamber 7 between connected entrance 6 and the plug 5, allow sediment-precipitating pipe 3 be in the oil pipe 4.Connected entrance 6 on the sediment-precipitating pipe shown in the accompanying drawing 3 is axial vertical slots, and connected entrance 6 can also be circumferential cannelure, also can be the intercommunicating pore that is distributed on the tube wall.Bindiny mechanism comprises box cupling 1 and outer tube 4, and box cupling 1 is connected with outer tube 4, and circle is provided with inner convex platform in the middle part of box cupling 1.The top cylindrical of suspension joint 2 is provided with that the inner convex platform on the circle cooperates in box cupling 1 middle part of outer lug boss and bindiny mechanism, and suspension joint 2 is hung in the bindiny mechanism.
When annotating vapour, steam enters annular space between outer tube 4 and the sediment-precipitating pipe 3, the descending oil reservoir that is injected into through connected entrance 6.When the dirty piece that steam injection string fouling on the utility model produces sinks, drop on 7 li in heavy dirty chamber in the sediment-precipitating pipe 3, therefore, dirty piece can not enter oil reservoir with steam.After notes vapour engineering construction was intact, this instrument was carried to ground with steam injection string, can clear up the dirts in the sediment-precipitating pipe 3.
The length of sediment-precipitating pipe 3 is by the dirt amount and the decision of notes vapour cycle of oil well, and sediment-precipitating pipe 3 can be formed by connecting by several pipes, increases the volume in heavy dirty chamber 7, so that can deposit more dirty piece, dirt.
The utility model is if use in horizontal well, and the top that just this instrument is connected the temperature-sensitive packer of steam injection string gets final product.
