DETAILED DESCRIPTION

[0033] Below, a horizontal well bidirectional testing and water finding tool and method scheme provided by the embodiment of the present invention will be described in detail through several specific embodiments.

[0034] Example 1

[0035] Please refer to Figure 1 and Figure 2 The present invention is a schematic diagram of the installation of a horizontal well bidirectional testing and water finding tool, the horizontal well bidirectional testing and water finding tool is characterized by comprising:

[0036] The first body 14 includes:

[0037] A first channel, wherein a first flow meter 4 is disposed in the first channel;

[0038] a second channel, wherein a second flow meter 18 is disposed in the second channel;

[0039] A pipe opening and closing device, which is used to control the conduction of the first channel or the second channel;

[0040] Current collecting device 12;

[0041] The pressing device 6 includes a frame and a follower component, wherein the follower component is connected to the frame, and when one side of the follower component is pressed, the follower component moves along the pressed direction;

[0042] The current collecting device 12 and the pressing device 6 are fixed outside the first body 14, one end opening of the first channel is located on one side of the current collecting device 12, and the other end opening of the first channel is located on the other side of the current collecting device 12, one end opening of the second channel is located on one side of the current collecting device 12, and the other end opening of the second channel is located on the other side of the current collecting device 12, one side of the following component is connected with one side of the current collecting device 12, and the other side of the following component is connected with the other side of the current collecting device 12, and the pipe opening and closing device is transmission connected with the following component.

[0043] In the above embodiment, the current collecting device 12 is used to be arranged between two perforations to separate the two perforation sections. The first body 14 is used to carry the current collecting device 12 on one hand, and the first body 14 is provided with a first channel and a second channel on the other hand. The first channel and the second channel are respectively installed with a one-way flow device, a water holdup meter and a flow meter. The flow meter is used to monitor the water content and flow rate of the fluid passing through the first channel or the second channel.

[0044] Among them, the nozzle opening and closing device and the pressure-actuating device 6 are used to adjust the conduction between the first channel and the second channel. The conduction principle is that after the flow collecting device 12 separates the two perforations, if the liquid flow pressure in the perforation section at one end of the flow collecting device 12 is greater than the liquid flow pressure in the perforation section at the other end, the end with higher pressure will gather liquid. Since the pressure-actuating device 6 is fixed outside the first body 14, the two ends of the follower component of the pressure-actuating device 6 are respectively connected to the two sides of the flow collecting device 12. Due to the flow collecting effect, the pressure gathered at one end of the flow collecting device 12 will become higher and higher, and the liquid at the higher end will apply a pressure to the follower component, and the follower component will move along the pressure direction. The follower component will generate a power, and the power will drive the nozzle opening and closing device to move. The nozzle opening and closing component can be a principle structure similar to a three-way valve, or it can be a structure of the present invention. Figure 2 The principle structure is that a plurality of connecting holes are used to connect the first channel and the second channel.

[0045] Finally, no matter which side of the collecting device 12 collects the flow, its pressing device 6 generates a power to drive the pipe opening and closing device to connect the first channel or the second channel. After the first flow meter 4 in the first channel or the second flow meter 18 in the second channel reads the flow value, the flow direction information of the liquid and its liquid volume can be obtained.

[0046] Example 2

[0047] For further information, please refer to Figure 2 or Figure 3 Another embodiment of a horizontal well bidirectional testing and water-finding tool of the present invention, the first body 14 has a first inner cavity inside, one end of the first body 14 has a first liquid outlet 8 and a second liquid outlet 10, the other end of the first body 14 has a first liquid inlet 7 and a second liquid inlet 9, the first liquid outlet 8 and the first liquid inlet 7 are the inlet and outlet of the first channel, the second liquid outlet 10 and the second liquid inlet 9 are the inlet and outlet of the second channel, the first flowmeter 4 is arranged between the first liquid outlet 8 and the second liquid outlet 10, and the second flowmeter 18 is arranged between the first liquid inlet 7 and the second liquid inlet 9.

[0048] In the above embodiment, the first channel and the second channel share a first inner cavity, and the first inner cavity establishes the first channel and the second channel in the first body 14 through the first liquid outlet hole 8, the second liquid outlet hole 10, the first liquid inlet hole 7 and the second liquid inlet hole 9. This structure can greatly optimize the internal structure of the first body 14, so that the production cost of the first body 14 is reduced. When this structure is adopted, when a water holdup meter 5 is used to measure the water content in the fluid, only one water holdup meter 5 needs to be set to simultaneously measure the water holdup of the fluid in the first channel or the second channel.

[0049] Example 3

[0050] For further information, please refer to Figure 2 or Figure 3 , another embodiment of a horizontal well bidirectional testing and water-finding tool of the present invention, the pipe opening and closing device is a second body 11, the second body 11 is slidably connected to the first body 14, one end of the second body 11 has a first conducting hole and a second conducting hole, the other end of the second body 11 has a third conducting hole and a fourth conducting hole, the distance between the first conducting hole and the third conducting hole is the same as the distance between the outlet and the inlet of the first channel, the distance between the second conducting hole and the fourth conducting hole is the same as the distance between the outlet and the inlet of the second channel, and the distance between the first conducting hole and the second conducting hole is different from the distance between the first liquid outlet 8 and the second liquid outlet 10.

[0051] In the above embodiment, the function of the nozzle opening and closing device is to control the conduction of the first channel or the second channel. The second body 11 is slidably connected to the first body 14, and the second body 11 can be tubular or plate-shaped that can fit outside the first body 14. The second body 11 has two groups of first conduction holes and third conduction holes corresponding to the first channel, and second conduction holes and fourth conduction holes corresponding to the second channel. When the second body 11 slides to one end, the first conduction holes and the third conduction holes are connected to the outlet and inlet of the first channel. At this time, the first channel is connected to the front and rear sides of the current collecting device 12, and the other parts of the second body 11 cover the outlet and inlet of the second channel, making it non-conductive; when the second body 11 slides to the other end, the second conduction holes and the fourth conduction holes are connected to the outlet and inlet of the second channel. At this time, the second channel is connected to the front and rear sides of the current collecting device 12, and the other parts of the second body 11 cover the outlet and inlet of the first channel, making it non-conductive.

[0052] In this structure, the distance between the first conduction hole and the second conduction hole is different from the distance between the first liquid outlet hole 8 and the second liquid outlet hole 10, which can ensure that when the second body 11 moves from one end to the other, it switches from a single first channel conduction to a single second channel conduction.

[0053] Example 4

[0054] For further information, please refer to Figure 2 or Figure 3 In another embodiment of a horizontal well bidirectional testing and water-finding tool of the present invention, the second body 11 can move to a first position and a second position on the first body 14 driven by the follower component. When the second body 11 moves to the first position, the first liquid outlet 8 and the first liquid inlet 7 are connected, and the second liquid outlet 10 and the second liquid inlet 9 are blocked. When the second body 11 moves to the second position, the first liquid outlet 8 and the first liquid inlet 7 are blocked, and the second liquid outlet 10 and the second liquid inlet 9 are connected.

[0055] In the above embodiment, the second body 11 can be moved to the first position or the second position by the pressing device 6 in the first body 14;

[0056] For example, when a higher water pressure is gathered on the left side of the current collecting device 12, the pressing device 6 is subjected to the pressure on the left side, and the follower component moves to the right side, driving the second body 11 to move to the right side. At this time, the second liquid inlet 9 and the second liquid outlet 10 are connected, and the second channel is conductive;

[0057] When higher water pressure is gathered on the right side of the collecting device 12, the pressing device 6 is subjected to the pressure from the right side, and the follower component moves to the left side, driving the second body 11 to move to the left side. At this time, the first liquid inlet 7 and the first liquid outlet 8 are connected, and the first channel is conductive.

[0058] In this embodiment, the second body 11 is moved to the fixed first position and the second position under the drive of the pressing device 6, which can effectively ensure that the first channel is connected or the second channel is connected at the relative position.

[0059] Example 5

[0060] For further information, please refer to Figure 2 or Figure 3 Another embodiment of a horizontal well bidirectional testing and water-finding tool of the present invention, wherein a first limit portion 15 is provided at one end of the first body 14, and a second limit portion 16 is provided at the other end. The second body 11 slides on the first body 14 and contacts the first limit portion 15 to stop, and then is located at the first position. The second body 11 slides on the first body 14 and contacts the second limit portion 16 to stop, and then is located at the second position.

[0061] In the above embodiment, by providing a first limit portion 15 and a second limit portion 16 for blocking the terminal position of the second body 11 sliding on the first body 14, the left end limit position and the right end limit position of the second body 11 sliding on the first body 14 are fixed, ensuring that the second body 11 can eventually move accurately to the first position or the second position.

[0062] Example 6

[0063] For further information, please refer to Figure 2 or Figure 3 , another embodiment of a horizontal well bidirectional testing and water finding tool of the present invention, the second body 11 is four blocking pieces and a connecting rod, each blocking piece has a through hole, and the four blocking pieces are connected by a connecting rod;

[0064] The first body 14 has a slide rail, and the second body 11 is slidably connected to the first body 14 along the axial direction of the first body 14 via the slide rail.

[0065] In the above embodiment, the blocking sheet and the connecting rod can reduce the overall weight of the second body 11, ensuring that the pressing device 6 can still push the second body 11 to connect the first channel or the second channel when subjected to weak water pressure.

[0066] Furthermore, the second body 11 composed of the blocking piece and the connecting rod slides on the first body 14 through the slide rail.

[0067] Example 7

[0068] For further information, please refer to Figure 2 or Figure 3 , another embodiment of a horizontal well bidirectional testing and water-finding tool of the present invention, the current collecting device 12 is a current collecting umbrella, the current collecting umbrella includes an umbrella rib 17, an umbrella support for opening the umbrella rib, an elastic part, a limit pin 12 and an electric switch device, the elastic part is transmission-connected to the umbrella rib 17 through the umbrella support, when the elastic part is in a compressed state, the limit pin 12 is stuck at the end of the elastic part, and the electric switch device and the limit pin 12 are transmission-connected.

[0069] In the above embodiment, the current collecting umbrella is composed of an umbrella rib 17, an umbrella support, an elastic part, a limit pin 12 and an electric switch device. Before the device is lowered into the well, the elastic part is compressed to make it carry energy. When the elastic part is compressed, the umbrella rib 17 and the umbrella support are assembled. After the device is lowered into the well, the electric switch device drives the limit pin 12 to cancel the limit effect of the limit pin 12 on the elastic part. The elastic part releases energy to open the umbrella rib 17 and the umbrella support, completing the opening of the current collecting umbrella and blocking it between the upper and lower perforations. The current collecting umbrella is a prior art.

Under the pressure of the higher water pressure on one side of the current collecting device 12, the current collecting membrane is deformed and deformed along the pressure direction of the water pressure. The deformation will generate a force, and the current collecting membrane drives the nozzle opening and closing device through the force. When the current collecting membrane is deformed to the left or to the right, the direction of the force is different, and the nozzle opening and closing device controls the conduction of the first channel or the second channel through the deformation forces in different directions.
