Because of adopting the double-layer pipe eccentric suspension structure, the tool can pass through the continuous oil pipe and can also correct the eccentric of the tool tightly connected with the upper part, and meanwhile, the tool is provided with double flow passages for transferring stratum fluid.
Description
Technical Field
The invention relates to a testing matched tool in oilfield development, in particular to an oil-water well eccentric normalization liquid conveying device which is mainly used in an oil-water well testing process requiring multi-channel overflow.
Background
The problem that the oil content is gradually reduced in the horizontal well which is applied in large scale in the earlier stage is solved, and the development and analysis of the oil field are very important to develop the research and analysis to clear the output profile. In developing a horizontal well production profile testing process, there is a need for a tool that can both penetrate the coiled tubing and naturally normalize the eccentricity of the upper, closely coupled tool, while also having dual flow paths for the transfer of formation fluids. However, the existing tools have no special function and cannot meet the severe requirements of special test processes.
Disclosure of Invention
In order to solve the problems, the invention provides an eccentric correcting liquid conveying device of an oil-water well, which can penetrate through a continuous oil pipe and can correct the eccentric of a tool with a tightly connected upper part, and meanwhile, the eccentric correcting liquid conveying device is provided with double flow passages for conveying stratum fluid.
The invention adopts the following technical scheme:
the eccentric correction liquid conveying device for the oil-water well comprises an outer cylinder and an eccentric pipe, wherein the eccentric pipe is arranged in the outer cylinder, a hanging inner shoulder is arranged in the outer cylinder, a hanging outer shoulder is arranged at the upper end of the eccentric pipe, the hanging outer shoulder is not coaxial with a main channel, an axial side flow channel is arranged on the hanging outer shoulder, and the hanging outer shoulder is hung on the hanging inner shoulder.
In a preferred embodiment, the lateral flow channel is an axial bore or an axial groove. A centralizer is disposed in the annulus between the outer barrel and the eccentric tube at a location on the inner suspension shoulder.
Compared with the prior art, the invention has the beneficial effects that:
because of adopting the double-layer pipe eccentric suspension structure, the tool can pass through the continuous oil pipe and can also correct the eccentric of the tool tightly connected with the upper part, and meanwhile, the tool is provided with double flow passages for transferring stratum fluid.

Detailed Description
The eccentric correction liquid conveying device for the oil-water well comprises an outer barrel 1 and an eccentric pipe 2, wherein the eccentric pipe is arranged in the outer barrel, a hanging inner shoulder 6 is arranged in the outer barrel, a hanging outer shoulder 4 is arranged at the upper end of the eccentric pipe, the hanging outer shoulder 4 is not coaxial with a main channel 7, an axial side flow channel 5 is arranged on the hanging outer shoulder 4, the side flow channel 5 is an axial hole, and the hanging outer shoulder 4 is hung on the hanging inner shoulder 6. In order to facilitate the connection of the tool and other tools, a centralizing body 3 is arranged below the lower part of the eccentric pipe 2 and below the hanging inner shoulder 6 in the annulus between the outer cylinder and the eccentric pipe, the lower end of the eccentric pipe which is in an eccentric state is centralized to be concentric with the outer cylinder, and the middle section of the eccentric pipe is bent due to the restraint of the hanging inner shoulder 6 and the centralizing body 3.
When the tool of the present invention is connected to the lower tool, the centralizer may not be installed when the diameter of the lower tool is large, and the larger outer diameter of the lower tool may be used as the centralizer as shown in fig. 2.
As shown in fig. 2 and 5, the side flow channel 5 may also be an axial groove, and the number of grooves may be more than 1.
The embodiments described herein are merely exemplary embodiments and are not limited to these embodiments, and those skilled in the art can make modifications without departing from the spirit and scope of the invention. Many variations, combinations and modifications of the arrangements disclosed herein are possible and are within the scope of the invention, and therefore the scope of protection is not limited to the description set out above, but is defined in accordance with the claims, the scope of protection including all equivalents of the subject matter of the claims.
