Abstract
The utility model relates to a stifled device is separated to oil development oil-water well, especially relates to a novel stifled device is separated to oil-water well. The technical scheme is as follows: the jet flow device comprises a jet flow hole, a piston, an elastic device, a cylinder body and a bolt, wherein the upper end of the cylinder body is connected to an oil pipe, the piston and the elastic device are sequentially arranged in an inner cavity of the cylinder body from top to bottom, and the outer wall of the cylinder body is provided with a plurality of jet flow holes. The beneficial effects are that: 1. the device is matched and relatively fixed, and can be flexibly used; 2. the structure is simple, the connection is convenient, and a special tool is not needed; 3. the depth of the stratum treated by the device is larger than that of other blockage removal methods which are popularized and used at present; 4. the method has the advantages of simple construction, low construction cost, easy popularization and the like.
Description
One, technical field:
The utility model relates to a kind of oil development plug removal in oil and water well device, particularly relates to a kind of novel plug removal in oil and water well device.
Two, background technology:
Traditional plug removal in oil and water well construction often adopts cementing truck to squeeze the method for chemical plugging removal agent in oil-water well, easily the stratum is damaged; Construct with cementing truck in addition, the construction cost height, and can not inject continuously.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of and can improve the de-plugging treatment effect, overcomes well or avoids the construction cost height, and the novel plug removal in oil and water well device of problem such as can not inject continuously.
Its technical scheme is: comprise jet orifice, piston, elastic device, cylinder body, bolt, terminate on the described cylinder body on the oil pipe that piston and elastic device are installed in the inner chamber of cylinder block from top to bottom successively, and the outer wall of described cylinder body is provided with a plurality of jet orifices.
Below, position when described a plurality of jet orifice is arranged on the piston extended state.
Described elastic device can be spring.
The beneficial effects of the utility model are: 1, matched with devices relative fixed, can use flexibly; 2, simple in structure, it is convenient to connect, and does not need to use special tool; 3, this device is handled the degree of depth on stratum greater than other method for removing blockage of promoting the use of at present; 4, have construction simply, operating expenses is low, is easy to advantages such as popularization.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, the specific embodiment:
In conjunction with the accompanying drawings, the utility model will be further described:
The groundwork principle is as follows:
Terminate on the utility model on the oil pipe, be lowered into the target zone handled of the de-plugging that requires, its working solution and power are provided by cementing truck.Arrive low frequency hydraulic vibration generator by the fluid that cementing truck pumped into by oil pipe, the fluid pressure on piston top acts on and makes descent of piston on the piston, jet orifice and top liquid flowing connection when the descent of piston certain distance, liquid stream sprays and impacts borehole or oil layer section from jet orifice, high speed, the stratum is imposed impact and compression process.At the same time, because liquid stream in piston top is communicated with the oil-water well annular space by jet orifice, thereby cause piston top head of liquid to reduce, piston is under the effect of lower springs and up, close jet orifice, the formation blockage thing of the pine that shaken is counter to be told in the well because bottom pressure reduces in this course, has experienced the counter motion process of a dilatational wave concerning the stratum, form the pressure pulse vibration so repeatedly, reach de-plugging purpose oil reservoir.
Claims (3)
1, a kind of novel plug removal in oil and water well device, it is characterized in that: comprise jet orifice, piston, elastic device, cylinder body, bolt, terminate on the oil pipe on the described cylinder body, piston and elastic device are installed in the inner chamber of cylinder block from top to bottom successively, and the outer wall of described cylinder body is provided with a plurality of jet orifices.
