Drawings
Preferred embodiments of the present invention will be described in detail below with reference to the attached drawing figures, wherein:
fig. 1 shows a simulation device according to an embodiment of the invention.
The figures are not drawn to scale.
Detailed Description
The invention will be further explained with reference to the drawings.
Fig. 1 shows a simulation device 100 for plugging an aqueous lost circulation zone according to the present invention. As shown in fig. 1, the simulation apparatus 100 includes a vessel 1, a simulated wellbore 2, a simulated drill pipe 3, and a lost circulation tank 4. Wherein the container 1 is constructed such that its inner cavity is observable and a liquid flow flowing in the direction from the left end to the right end is formed in the inner cavity for simulating a thief channel of an aqueous thief zone. A simulated wellbore 2 is provided in the top wall of the vessel 1 and is in communication with the vessel 1 for simulating a drilling wellbore. The dummy drill pipe 3 is inserted into the inner cavity of the dummy wellbore 2. The dummy drill pipe 3 is configured to be rotatable about its own axis for simulating a drill pipe for drilling. The plugging slurry tank 4 can be selectively communicated with the inner cavity of the simulation shaft 2 and also can be selectively communicated with the inner cavity of the simulation drill rod 3 so as to pump plugging slurry into the simulation shaft 2 or/and the simulation drill rod 3 according to requirements.
Therefore, the simulation apparatus 100 can simulate the water flow of the water-containing leakage layer by the liquid flow of the container 1, and can simulate the water flow speed of the stratum, the stratum temperature, the size of the leakage passage and the like by adjusting the speed and the temperature of the liquid flow of the container 1 and the size of the container 1, so that the simulation is closer to the real leakage environment. Different plugging materials or plugging slurry are pumped into the container 1 through the plugging slurry tank 4 to observe the plugging effect and guide the site plugging construction of the water-containing leakage layer. In addition, the simulation device 100 has clear principle, simple structure and convenient operation, and has better guiding function for selecting the plugging material of the water-containing leakage layer.
In one embodiment, the inner surfaces of the top and bottom walls of the container 1 are provided with cement or teflon sheets for better simulation of the formation environment. And the front and rear walls of the container 1 may be constructed as transparent walls for the convenience of the observer. For example, the container 1 may be made of transparent glass or transparent plastic, and cement board or teflon board is distributed on the top and bottom walls of the container 1, or the top and bottom walls of the container 1 are themselves made of cement board or teflon board. A movable plate (not shown in the figures) may be optionally provided on the bottom wall of the container 1, the shape of the movable plate matching the shape of the bottom wall of the container 1, so that the height of the container 1 can be adjusted after the movable plate is put in. By this arrangement, leakage paths of different sizes can be simulated to increase the applicability of the simulation apparatus 100. Of course, it is understood that the movable plate may be made of cement or teflon plate as required, and the movable plate may be selectively and correspondingly disposed on different walls in order to adjust the dimensions of the container 1 in different directions.
The body of the container 1 may be constructed in a generally square body structure. And the left end portion is constructed in a trapezoidal structure such that the flow area gradually increases in a direction from the left end to the right end. The container 1 of this construction facilitates access to the fluid flow and ensures that the fluid flow is distributed in a relatively uniform manner within the downstream body. For better simulation of the formation, it should be noted that the fluid stream is water. Preferably, a shower head (not shown) is provided at the left end inlet of the vessel 1. For example, the shower head can control water outlet through the water separator, so that the shower head has a multi-gear water adjusting mode, water flows out through different numbers of shower head holes in an adjusting mode, or water flows out through different flow rates in an adjusting mode. It is further preferred that a sieve (not shown in the figures) is provided in the inner chamber of the container 1, which sieve is arranged downstream of the shower head. The screen receives water from the shower head to further disperse the water evenly to flow into the body of the vessel 1 to more realistically simulate the formation environment.
Of course, the right end portion of the container 1 is constructed in a trapezoidal structure such that the flow area gradually decreases in the direction from the left end to the right end. That is, the container 1 may be constructed in a substantially symmetrical structure about the left and right centers for easy manufacturing. Meanwhile, the right end of the container 1 having the above structure helps to receive the liquid flow and smoothly discharge the liquid flow from the container 1. For example, the container 1 may be constructed with a length and width of 500mm 200mm 100mm, where the length and width refer to the overall dimensions of the container 1, e.g., length is the distance from the left end to the right end, width is the distance between the front and rear sides, and height is the distance between the top and bottom ends.
The simulation device 100 further comprises a first liquid source 5 for supplying water to the container 1. The first liquid source 5 is provided with a heater 6 for heating the first heat source 5 and supplying a liquid of a desired temperature into the container 1. Structurally, the left end inlet of the vessel 1 is in selective communication with a first liquid source 5 via a leak inlet line 7. And the right end outlet of the vessel 1 is in selective communication with the first liquid source 5 via a thief outlet line 8. A liquid circulation is established between the first liquid source 5 and the container 1. A first pump 9 is provided on the thief inlet line 7 to pump a liquid stream into the vessel 1. The first pump 9 may be a screw pump or a vane pump, for example. Through the arrangement, the liquid with certain temperature, flow rate and pressure can be controllably pumped into the container 1, and the container is used for simulating the stratum in a more comprehensive mode.
A selectively communicable leak-back pressure line 10 is provided between the vessel 1 and the first liquid source 5 for performing a reflux operation. For example, after the right end outlet of the container 1 is blocked, the container 1 can be depressurized through the leak back pressure line 10.
The simulated wellbore 2 is a cylinder, which may be made of transparent tempered glass or transparent plastic. For example, the simulated wellbore may be 1000mm high and 80mm internal diameter. A sealing cover (not shown) is sealingly arranged on the simulated shaft 2. The dummy drill pipe 3 is a steel pipe which extends through a sealing cap in the inner cavity of the dummy wellbore 2. For example, the simulation drill pipe 3 is arranged in the simulation well bore 2 in a central manner, the upper end of the simulation drill pipe is positioned outside the simulation well bore 2, and the simulation drill pipe is connected with the motor 12 and used for rotating under the driving of the motor 12, so that the actual condition of stratum drilling is simulated.
The plugging slurry tank 4 is selectively connected to the simulated wellbore 2 by a first plugging slurry input line 19. The plugging slurry tank 4 is selectively connected with the simulation drill pipe 3 through a second plugging slurry input pipeline 20.
The simulation device 100 also includes a second liquid source 13 for applying pressure to the lost circulation mud tank 4. The leaking stoppage slurry tank 4 is, for example, a steel-made airtight tank. Preferably, a piston is arranged in the inner cavity of the leaking stoppage slurry tank 4 and is used for dividing the inner cavity into an upper cavity and a lower cavity which are independent mutually. It will be appreciated that the lower chamber holds the plugging slurry, while the upper chamber is in communication with a second source of liquid 13. The lost circulation slurry tank 4 is selectively connected to a second liquid source 13 by a pressure application line 14. A second pump 15 is provided on the pressure application line 14. In the working process, pressure water is pumped into the plugging slurry tank 4 through the second pump 15, enters the cavity at the upper part of the piston and applies force on the piston, and then the piston applies force on the plugging slurry and sends the plugging slurry into the simulation shaft 2 or the simulation drill rod 3. The water and the leaking stoppage slurry can be well isolated by the arrangement, so that water is prevented from entering the leaking stoppage slurry, and the plugging effect of the leaking stoppage slurry is further accurately evaluated. In addition, a pressure-applying back-pressure pipeline 16 which can be selectively communicated is arranged between the second liquid source 13 and the leaking stoppage slurry tank 4 and is used for releasing the pressure of the water in the leaking stoppage slurry tank 4 back to the second liquid source 13 after the test is finished.
In this application, at least two sets of leaking stoppage slurry tanks 4 are included. This arrangement may be used in a set of lost circulation slurries, such as epoxy grout, including two scenarios requiring separate pumping of sets of materials, such as A, B. For example, the substance a in the plugging slurry may be pumped into the simulated wellbore 2 through one set of plugging slurry tanks 4, while the substance B in the plugging slurry may be pumped into the simulated drill pipe 3 through another set of plugging slurry tanks 4, after mixing the substance a and the substance B in the container 1 for the plugging performance test. And the volume of each plugging slurry tank 4 is 0.5-1 times of the volume of the container 1, so that in the test process, the plugging slurry can be pumped into the container 1 in an amount which accounts for sixty percent to ninety-five percent of the container 1, and the plugging slurry can be used for better judging whether the plugging slurry is effective or not. It is easy to understand that each leaking stoppage slurry tank 4 needs to be provided with relevant components such as the second liquid source 13, the second pump 15 and the like in a matching manner.
The simulation apparatus 100 further includes a memory (not shown in the figure), a pressure gauge 17, and a flow meter 18. For example, a plurality of pressure gauges 17 for sensing different places are provided at different positions on the container 1. Meanwhile, the pipeline where the first plugging slurry input pipeline 19 and the second plugging slurry input pipeline 20 are merged is also provided with a pressure gauge 17 and a flow meter 18 at intervals, and the pressure gauge 17 is closer to the plugging slurry tank 4 than the flow meter 18. A flow meter 18 is also provided in the combined leak inlet line 7 and leak return line 10. Each of the pressure gauge 17 and the flow meter 18 is in signal communication with a memory for transferring the measured pressure or flow signal to the memory, which stores the data for subsequent analysis. Of course, on each line, a valve 21 is also provided in order to achieve the closing and opening of the line.
The operation of the simulation apparatus is described in detail below with reference to fig. 1.
During the test, the first liquid source 5 and the second liquid source 13 are ensured to have sufficient water. The water of the first liquid source 5 is heated to a prescribed temperature by the heater 6 and maintained at this temperature. And adding the plugging slurry into the plugging slurry tank 4. Such that water from the first source 5 flows through the container 1. At the same time, water from the second source 13 is pumped to the lost circulation mud tank 4 to apply pressure thereto. The discharge capacity of the first pump 9 is controlled well according to the test requirements, so that the water flow speed flowing through the container 1 meets the test requirements, and the leaking stoppage slurry in the leaking stoppage slurry tank 4 also meets the pumping speed requirements. During the test, the values of each pressure gauge 17 and flow meter 18 were recorded by a memory. And observing and recording the plugging condition of the plugging slurry in the container 1 so as to evaluate the plugging effect of the plugging slurry. For example, if the plugging slurry is left in a relatively large amount right below the simulated wellbore 2 under the same pumping conditions, it can be determined that the plugging slurry has a more superior plugging effect under the conditions.
It should be noted that the terms "left", "right", "upper", "lower", "top", "bottom", and the like in the present application indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
The above is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily make changes or variations within the technical scope of the present invention disclosed, and such changes or variations should be covered within the scope of the present invention.
