Abstract
The utility model discloses a high-low pressure cleaning agent jet flow descaling device, which consists of a filter, a check valve, a centralizer, a damper and a rotating nozzle. The filter comprises a primary filter and a secondary filter; the primary filter is arranged at the top end of the descaling device; the primary filter is connected with the secondary filter through the check valve; the tail end of the secondary filter is connected with the centralizer; the tail end of the centralizer is connected with the damper; and the tail end of the damper is connected with the rotating nozzle. The descaling device can remove pollution and blockage in a zone near an oil-water well and provides a clean flow channel for oil and gas flow or water injection.
Description
Technical field
The utility model relates to a kind of high-low pressure medicament jet apparatus for eliminating sludge.
Background technology
At present, the many oil fields of China have entered the exploitation middle and later periods, present the heterogeneous body oil field of trend, particularly some waterflooding extractions that moisture rising, oil production successively decrease, and this trend is more obvious.In order to keep stable yields or minimizing declining rate of recovery, in recent years, domestic and international one side is marginal field development and viscous crude and LOW PERMEABILITY RESERVOIR energetically, on the other hand, studies and use various enhanced recovery modes and technology energetically.
Generally speaking, the enhanced recovery mode nothing more than trick in two aspects: the one, consider from whole oil reservoir, improve oil displacement efficiency and underground residual oil development degree that oil-bearing stratum flooding involves scope, displacement of reservoir oil medium, finally improve oil recovery factor; The 2nd, have in mind from individual well, adopt the stratum action method of mechanical oil recovery means and various physics, chemistry, implement enhancements, improve oilwell produced fluid amount and increase the well water injection rate.
Concerning individual well, owing to liquid contamination in drilling well, completion, underground work and long-term oil recovery, the water filling manufacturing process and the obstruction of mechanical admixture precipitation, cause the near wellbore permeability reduction inevitably, cause oil production and water injection rate to descend even stopping production.
The utility model content
The utility model technical issues that need to address just are to provide a kind of high-low pressure medicament jet apparatus for eliminating sludge, and it can remove the contamination and plugging of oil-water well near wellbore zone, and the flow channel of a cleaning is provided for gas stream or water filling.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of high-low pressure medicament of the utility model jet apparatus for eliminating sludge, described apparatus for eliminating sludge is made of strainer, one way valve, centralizer, damper and rotary nozzle, described strainer comprises grade one filter and secondary filter, grade one filter is arranged at the top of apparatus for eliminating sludge, connect by one way valve between grade one filter and the secondary filter, the tail end of secondary filter connects centralizer, and the tail end of centralizer connects damper, and the tail end of damper connects rotary nozzle.
The utility model is used to remove oil-water well near wellbore zone contamination and plugging, and the flow channel of a cleaning is provided for gas stream or water filling.During construction, the utility model apparatus for eliminating sludge is delivered to down-hole de-plugging perforated interval by oil pipe, and the ground pump truck turn on pump is suppressed, and clear water produces turning moment by the side direction nozzle, drives the rotary nozzle rotation, and rotary speed is by Damper Control.Ground working vehicle makes whole apparatus for eliminating sludge move up and down at perforated interval simultaneously.Borehole is produced direct, discontinuity, powerful waterpower pulse pressure, remove perforation plugging.
Advantage of the present utility model has:
1, simple in structure, cost is low.
2, concentration of energy, the processing degree of depth are big.
3, working media is clear water, and is pollution-free.
4, easily be used in combination with other technology.
5, can select jet pressure, additive, rotary speed, processing interval and processing time according to stopping up the type and the order of severity, easy to use flexible.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, a kind of high-low pressure medicament of the utility model jet apparatus for eliminating sludge, described apparatus for eliminating sludge is made of strainer, one way valve 2, centralizer 4, damper 5 and rotary nozzle 6, described strainer comprises grade one filter 1 and secondary filter 3, grade one filter is arranged at the top of apparatus for eliminating sludge, connects by one way valve between grade one filter and the secondary filter, and the tail end of secondary filter connects centralizer, the tail end of centralizer connects damper, and the tail end of damper connects rotary nozzle.
The utility model is used to remove oil-water well near wellbore zone contamination and plugging, and the flow channel of a cleaning is provided for gas stream or water filling.During construction, the utility model apparatus for eliminating sludge is delivered to down-hole de-plugging perforated interval by oil pipe, and the ground pump truck turn on pump is suppressed, and clear water produces turning moment by the side direction nozzle, drives the rotary nozzle rotation, and rotary speed is by Damper Control.Ground working vehicle makes whole apparatus for eliminating sludge move up and down at perforated interval simultaneously.Borehole is produced direct, discontinuity, powerful waterpower pulse pressure, remove perforation plugging.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this manual has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in the claim scope of the present utility model.
