Abstract

The utility model discloses a cleaning device of an oil rod and an oil tube in a well casing. The cleaning device comprises a ground high-temperature high-pressure steam generator, a slotting pipe and an outer barrel, wherein the slotting pipe is arranged in the outer barrel, and the steam outlet of the high-temperature high-pressure steam generator is communicated with the outer barrel. The cleaning device disclosed by the utility model finishes thorough cleaning of the oil rod, the oil tube and tools in a well in the well casing, greatly reduces the pollution to the ground environment and equipment and the waste of crude oil, and greatly shortens the construction cycle.

Description

Beam hanger oil pipe cleaning device in a kind of pit shaft

Technical field

The utility model belongs to instrument cleaning technique field in oil, the well, beam hanger oil pipe cleaning device in particularly a kind of pit shaft.

Background technology

After crude oil temperature dropped to freezing point, the wax partial crystallization went out and is interconnected to form spacial framework, and liquid hydrocarbon then is divided into decentralized photo; Crude oil is lost flowability, promptly take place so-called solidify and the inside and outside wall attached to instrument in beam hanger, pipe and the well on, trip out OIH bar, pipe during operation; When cleaning on ground; Prolonged construction period greatly, and caused the severe contamination of ground environment and numerous equipment, owing to demifacet outer wall under the limitation of putting, beam hanger, the pipe cleans not thorough.

Summary of the invention

The utility model main purpose is in order to address the above problem; Provide a kind of in pit shaft, the completion that instrument in beam hanger, oil pipe and the well is cleaned completely; Reduce the pollution and the oil loss of ground environment, equipment, and can shorten the interior beam hanger of pit shaft, the oil pipe cleaning device of construction period greatly.

In order to achieve the above object, the technical scheme that the utility model provides is: beam hanger oil pipe cleaning device in a kind of pit shaft, and it comprises ground high temperature and high pressure steam generator, slot pipe and urceolus; The slot pipe places in the urceolus; The gas outlet of high temperature and high pressure steam generator is communicated with urceolus;

The slot pipe is oblique laser slotted pipe.

When the utility model uses, the utility model is installed on pit shaft inner oil tube top and is connected with oil pipe or places in the annular space between pit shaft and the oil pipe.The high temperature and high pressure steam that the utility model is produced by the high temperature and high pressure steam generator; Get into the annular space of urceolus and slot pipe through surface line, in pit shaft, through to just in trip-out process beam hanger, oil pipe thermodynamic energy constantly is provided; Steam carries out interchange of heat with the crude oil that is set in instrument inside and outside wall in beam hanger, oil pipe and the well; Raising reduces this viscosity attached to the temperature of the crude oil of beam hanger, oil pipe surface solidification, and the crude oil that beam hanger, oil-pipe external wall are adhered to constantly melts; Comprehensive through 360 ° of high temperature and high pressure steams again, (high-temperature steam is flow to the annular space of pit shaft inner/outer tube and laser slotted pipe to thorn brush power through pipeline by the ground steam generator; The flow of the oblique gap of the oblique gap through the laser slotted pipe, slot pipe control steam so just constitutes the injection of steam again, and the component straight down of angular injection power just produces to be brushed the thorn of beam hanger, oil pipe) effect under; Cause the crude oil of thawing constantly to come off, in pit shaft, accomplish the cleaning completely of instrument in beam hanger, oil pipe and the well.

Fig. 3: the third utilization structure sketch map of the utility model;

The specific embodiment:

Embodiment 1:

As shown in Figure 1: beam hanger oil pipe cleaning device in a kind of pit shaft, it comprises ground high temperature and high pressure steam generator 1, slot pipe 2 and urceolus 3; Slot pipe 2 places in the urceolus 3; The gas outlet of high temperature and high pressure steam generator 1 is communicated with urceolus 3;

Slot pipe 2 is oblique laser slotted pipe.

As shown in Figure 1, during use the utility model is installed in oil pipe 6 tops in the pit shaft 5 and is connected with oil pipe 6, beam hanger 7 passes slot pipe 2.

Embodiment 2:

As shown in Figure 2: the difference of present embodiment and embodiment 1 is during use the utility model to be installed in the annular space between pit shaft 5 and the oil pipe 6.

Embodiment 3:

As shown in Figure 3: the difference of present embodiment and the foregoing description is during use the utility model to be installed in pit shaft 5 tops.

The high temperature and high pressure steam that the utility model is produced by ground high temperature and high pressure steam generator 1; Get into the annular space of urceolus 3 and slot pipe 2 through surface line; In pit shaft 5; Through to the just beam hanger in trip-out process 7, oil pipe 6 thermodynamic energy being provided constantly, steam carries out interchange of heat with the crude oil that is set in instrument inside and outside wall in beam hanger 7, oil pipe 6 and the well, improves the temperature attached to the crude oil of beam hanger 7, oil pipe 6 surface solidification; Reduce this viscosity; The crude oil that beam hanger 7, oil pipe 6 outer walls are adhered to constantly melts, and (high-temperature steam is controlled the flow of steam through the oblique gap of slot pipe 2, the oblique gap of slot pipe 2 again by the urceolus 3 of high temperature and high pressure steam generator 1 in pipeline flows to pit shaft 5 and the annular space of slot pipe 2 through 360 ° of comprehensive thorn brush power of high temperature and high pressure steam again; So just constitute the injection of steam; The component straight down of angular injection power just produces the thorn brush to beam hanger 7, oil pipe 6) effect under, cause the crude oil of thawing constantly to come off, the cleaning completely of instrument in completion beam hanger 7, oil pipe 6 and the well pit shaft 5 in.
