This technology includes foam drilling, foam well washing, foam sand washing, foam cementing, foam fracturing and acidizing, foam well testing, and foam profile control and water plugging, etc. Using foam as the circulating fluid for workover and drilling operations began in the 1960s. Foam fluid is an underbalanced drilling medium, which is composed of water, gas, foaming agent, stabilizer and other chemical agents. Using foam fluid to carry out drilling work can increase the drilling speed, avoid or reduce drilling accidents, reduce formation damage, increase the production of single wells, facilitate the discovery of oil and gas reservoirs, protect the environment, reduce the operation cost of stimulation measures, and particularly play an important role in the development of low-permeability, low-pressure reservoirs, unconventional oil and gas resources, and the transformation of old oil and gas fields.

[0072] Embodiment 1

[0073] Embodiment 1 of the present invention provides a foam fluid generating system, the structure of which is as Figure 1 shown, including: a control system 11, a manifold system 12, and a foam generating device 13;

[0074] The manifold system 12 includes a base fluid input manifold, a gas input manifold, and a foam output manifold;

[0077] In some alternative embodiments, for the structures of the manifold system 12 and the foam generating device 13 in the above-mentioned foam fluid generating system, refer to Figure 2 as shown. Among them: the base liquid input manifold, the gas input manifold, and the foam output manifold included in the manifold system 12 are connected to the foam generator in the foam generating device 13. The foam generator is connected to the motor. The base liquid input manifold supplies the base liquid to the foam generator, and the gas input manifold supplies the gas to the foam generator. The foam generator makes the base liquid and the gas interact with each other to generate bubbles under the drive of the motor, and the generated bubbles are output from the foam output manifold. Different types of monitoring instruments and control valves are provided on each manifold, and the density of the foam can be adjusted according to the readings of the monitoring instruments and the opening degrees of the control valves, and the dispersion degree of the foam can be controlled by changing the rotational speed of the motor.

[0078] Preferably, the base liquid input manifold in the above-mentioned manifold system 12 includes: a base liquid input pipeline, a check valve, an electric on-off valve, an electronic flowmeter, and an electronic pressure gauge;

[0079] The base liquid input pipeline is used to input the foam base liquid into the foam generator in the foam generating device;

[0086] The check valve is used to control the input direction and flow rate of the gas;

[0087] The electric on-off valve is used to control the on-off of the gas input pipeline;

[0088] The electronic flowmeter is used to monitor the real-time gas flow rate in the gas input pipeline;

[0089] The electronic pressure gauge is used to monitor the real-time gas pressure in the gas input pipeline.

[0090] The foam output manifold in the above-mentioned manifold system 12 includes: a foam output pipeline, a check valve, an electric on-off valve, an electronic density meter, and an electronic pressure gauge;

[0091] The foam input pipeline is used to output the foam in the foam generator;

[0092] The check valve is used to control the output direction and flow rate of the foam;

[0093] The electric on-off valve is used to control the on-off of the foam output manifold;

[0094] The electronic density meter is used to monitor the real-time density of the foam in the foam output pipeline;

[0095] The electronic pressure gauge is used to monitor the real-time pressure of the foam output in the output pipeline.

[0096] The control valves and monitoring instruments in the above-mentioned manifold system 12 can collect the real-time monitoring data in the pipeline, provide it for the control system to use, and execute various instructions issued by the control system.

[0097] In some alternative embodiments, for the structure of the above-mentioned control system 11, refer to Figure 3 as shown, it includes: a system controller and a control terminal;

[0098] The system controller is used to obtain the foam shape parameters of the foam output from the foam output manifold, the real-time flow rate of the base liquid in the base liquid input manifold and the real-time gas flow rate of the gas input manifold, and the real-time density of the foam in the foam output manifold, and provide them to the control terminal; and adjust the real-time rotational speed of the motor according to the instructions of the control terminal to adjust the foam shape, and / or adjust the control parameter of the control valve of the base liquid input manifold and / or the gas input manifold according to the instructions of the control terminal to adjust the density of the foam output in the foam output pipeline;

[0099] A control terminal is used to determine the real-time rotational speed of the motor in the foam generating device after adjustment according to the required foam shape when it is determined that the foam shape does not meet the requirements based on the foam shape parameters output from the foam output manifold, and provide it to the system controller; and when it is determined that the density of the output foam does not meet the requirements based on the real-time density of the foam in the foam output manifold, determine the control parameters of the control valve of the base liquid input manifold and / or the control parameters of the control valve of the gas input manifold according to the real-time flow rate of the base liquid in the base liquid input manifold, the real-time flow rate of the gas in the gas input manifold, the real-time density of the foam, and the target density of the foam, and provide them to the system controller.

[0100] The shape of the foam can be determined by the shape parameters of the foam. The shape parameters include the average outer diameter of the foam, the volume of the foam, the dispersion degree of the foam, etc. In this embodiment, the dispersion degree is taken as an example to adjust the shape of the foam. During the specific construction process, different foam shape parameters can be set according to the needs of the site to meet the construction requirements and generate foam that meets the exploration work.

[0101] Preferably, the control terminal is specifically configured to obtain the dispersion degree of the foam in the foam output manifold in the foam generating device provided by the system controller; determine whether the dispersion degree of the foam meets the requirements according to the dispersion degree of the foam in the foam output manifold; if it does not meet the requirements, determine the real-time rotational speed of the motor after adjustment according to the required dispersion degree of the foam, and provide it to the system controller; wherein, the real-time rotational speed of the adjusted motor is determined by the following formula: D = K * V a , where K is a fixed coefficient determined by the size parameters of the foam generating device; a is an empirical coefficient; D is the dispersion degree of the foam; V is the real-time rotational speed of the motor.

[0102] It can be obtained from the above formula that the rotational speed of the motor determines the dispersion degree of the foam. The faster the rotational speed of the motor, the more foam is generated, the denser the dispersion degree, and the smaller the size of the foam; the slower the rotational speed of the motor, the less foam is generated, the sparser the dispersion degree, and the larger the size of the foam; by adjusting the rotational speed of the motor, fine production can be completed to generate foam with different dispersion degrees. When applying the foam fluid generating system provided by this embodiment, the rotational speed of the motor can be adjusted in the control terminal to make the motor work at the rotational speed input by the user to generate foam that meets the requirements. Correspondingly, when it is necessary to change the dispersion degree of the foam, the rotational speed of the motor also needs to be increased or decreased accordingly to change the dispersion degree of the foam.

[0103] Preferably, the control terminal is specifically configured to obtain the real-time flow rate of the base fluid in the base fluid input manifold and the real-time flow rate of the gas in the gas input manifold provided by the system controller, and the real-time density of the foam in the foam output manifold; determine whether the density of the foam meets the requirements according to the real-time density of the foam in the foam output manifold; if not, determine the adjustment amount of the real-time flow rate of the base fluid in the base fluid input manifold and / or the adjustment amount of the real-time flow rate of the gas in the gas input manifold according to the magnitude relationship between the target density and the real-time density of the foam, the real-time flow rate of the base fluid in the base fluid input manifold, and the real-time flow rate of the gas in the gas input manifold, and provide it to the system controller.

[0104] Theoretically, the density of the foam is expressed by the following formula: ρ 泡 =(Q 液 *ρ 液 ) / (Q 气 +Q 液 )

[0105] The derivation process of this formula is as follows:

[0106] Since there are the following relationships among the mass, volume, flow rate, and density of substances:

[0107] M = Q * t * ρ

[0108] V = M / ρ = Q * t

[0109] where M represents mass, ρ represents density, Q represents flow rate, t represents time, and V represents volume;

[0110] For foam, its density can be expressed as follows:

[0111] ρ 泡 = M / V = (Q 气 * t * ρ + Q 液 * t * ρ) / (V 气 + V 液 )

[0112] ≈ (Q 液 * t * ρ 液 ) / (Q 气 * t + Q 液 * t) = (Q 液 * ρ 液 ) / (Q 气 + Q 液 )

[0113] where Q 气 represents the real-time flow rate of the gas in the gas input manifold, Q 液 represents the real-time flow rate of the base fluid in the base fluid input manifold, and ρ 液 represents the density of the base fluid.

[0114] As can be seen from the above formula, since ρ 液 is an inherent property of the base liquid itself, the density of the foam is determined by the flow rates of the gas and the foam base liquid. That is to say, the density of the foam can be adjusted by adjusting the real-time flow rate of the base liquid in the base liquid input manifold and / or the real-time flow rate of the gas in the gas input manifold. Using this adjustment method, the fine production of the foam can be controlled, without being restricted by the mechanical structure of the traditional foam production device, and the density of the foam can be displayed in real time on the control terminal and the adjustment amount can be determined to realize the intelligent production of the foam.

[0115] Preferably, the control terminal has a man-machine interface for displaying the real-time speed of the motor in the foam generating device, the real-time flow rate of the base liquid in the base liquid input manifold and the real-time flow rate of the gas in the gas input manifold, the real-time density of the foam in the foam output manifold, and obtaining the motor speed and control valve control parameters input by the user through the man-machine interface, and providing them to the system controller.

[0116] For an example diagram of the man-machine interface of the control terminal, see Figure 4 As shown, the control terminal receives and displays the real-time speed of the motor in the foam generating device, the real-time flow rate of the base liquid in the base liquid input manifold and the real-time flow rate of the gas in the gas input manifold, the real-time density of the foam in the foam output manifold. The flow rate is measured by an electronic flowmeter and then uploaded for display. The real-time density of the foam is monitored by an electronic density meter on the foam output manifold and the data is uploaded for display. The control terminal can view the inflow or outflow volume values of each manifold. At the same time, the pressure data entering the foam generating device for each path can be viewed; the speed of the motor can also be displayed in real time, and there are adjustment buttons to increase or decrease the speed of the motor, thereby adjusting the dispersion degree of the generated foam. The electric switch valves on each path can also be modified to adjust the flow rate. Through the control terminal, the user can modify the switch parameters of the electric switch valves, that is, modify the liquid input volume and gas input volume, to change the density value of the generated foam, and the density value of the foam can be displayed in real time on the software interface for the user to view. Through the control of the control terminal, the fine production of the foam can be realized, high-quality foam can be generated, and at the same time, the labor intensity of manual work is saved.

[0117] Figure 3 For the control system shown, multiple functional modules are integrated in the system controller. The system controller is connected to the data acquisition line and the valve control line of the manifold system for data exchange. The system controller is connected to the computer control terminal to transmit the acquired data to the control terminal for display. Correspondingly, the control terminal sends the parameters input by the user to the system controller, and the system controller processes the data to realize the control of the entire system.

[0118] Preferably, the system controller includes: a signal acquisition module, a core control module, an electric switch valve drive module, a power supply module, and a motor drive module;

[0119] The signal acquisition module is used to collect the foam shape parameters output in the foam output manifold, the real-time flow rate of the base liquid in the base liquid input manifold and the real-time flow rate of the gas in the gas input manifold, the real-time density of the foam in the foam output manifold, and the real-time speed of the motor in the foam generator, and transmit them to the control terminal; the signal acquisition module can obtain monitoring data from instruments such as presses, density meters, flow meters, electric switch valves, and check valves in the manifold system, convert physical information into electrical signals, provide them for system control processing, and then upload them to the control terminal of the upper computer for display and use.

[0120] The core control module is used to control the motor drive module to adjust the real-time speed of the motor to adjust the foam dispersion degree according to the control terminal instructions, and / or control the electric switch valve drive module to adjust the control valve control parameters of the base liquid input manifold and / or the gas input manifold according to the control terminal instructions to adjust the density of the foam output in the foam output pipeline; this module realizes the operation and processing of data and the sending and receiving of instructions, can exchange data with the control terminal, and also directly or indirectly controls the manifold system and the foam generation device.

[0121] The electric switch valve drive module is used to control the opening, closing, and opening degree when opening of the valves in the base liquid input manifold, the gas input manifold, and the foam output manifold; when the opening degree is 0%, it means the valve is completely closed. When the opening degree is 100%, it means the valve is completely open.

[0122] The power supply module is used to provide power for the foam generator; the power supply module can convert the input conventional voltage into the voltages required by different devices. For example, the voltages required by motors, valves, and monitoring instruments in the pipeline are not the same, and the power supply module can output the required voltages for them.

[0123] The motor drive module is used to drive the motor to rotate, adjust the speed of the motor, and control the start and stop of the motor. It includes implementing the speed control, start, and stop operations of the motor according to the instructions of the core control module.

[0124] The system controller in the above control system 11 can be set separately or together with the foam generator. The above control terminal can be a personal computer, and a control software is installed in the personal computer to perform man-machine interaction operations. The control terminal includes a man-machine interaction interface, which displays various monitoring data monitored by the monitoring instruments in the manifold system, such as flow rate, pressure, valve opening degree, etc., as well as the working parameters of the foam generator and the motor, such as the speed of the motor, etc., and obtains various operation instructions input by the user, such as the adjustment amount of the valve opening degree and the adjusted motor speed.

[0125] In the above system of this embodiment, when it is determined that the foam shape does not meet the requirements according to the foam shape parameters output from the foam output manifold, the real-time rotation speed of the motor in the foam generating device is controlled according to the required foam shape to adjust the foam shape. Compared with the traditional method, this system is not restricted by the mechanical structure and can achieve fine production of foam through the control of the control system, generating high-standard foam fluid. And when it is determined that the density of the output foam does not meet the requirements according to the real-time density of the foam in the foam output manifold, the control parameters of the control valves of the base liquid input manifold and / or the gas input manifold are adjusted according to the real-time flow rate of the base liquid in the base liquid input manifold, the real-time flow rate of the gas in the gas input manifold, the real-time density of the foam, and the target density of the foam, so as to adjust the density of the foam output in the foam output pipeline. Through the control of the control system, the real-time parameters in each manifold are adjusted to adjust the density of the foam, and fine production can be carried out according to the target density of the foam required by the user, generating high-standard and high-quality foam, improving the production efficiency of the foam, saving costs, and being more economically feasible.

[0126] Regarding the foam fluid generation system in the above embodiment, the specific ways in which each module performs operations have been described in detail in the embodiments related to the method, and will not be elaborated here.

[0127] Embodiment 2

[0128] Based on the above foam fluid generation system, Embodiment 2 of the present invention provides a foam fluid generation method, including:

[0129] According to the real-time output parameters of the motor in the foam generating device and the foam shape parameters in the foam output pipeline, control the real-time rotation speed of the motor to adjust the foam dispersion degree; and according to the real-time flow rate parameters of the base liquid input pipeline and the gas input pipeline, and the physical property parameters of the foam in the foam output pipeline, control and adjust the control parameters of the control valves of the base liquid input pipeline and the gas input pipeline to adjust the physical property parameters of the foam output in the foam output pipeline.

[0130] Preferably, when it is determined that the foam shape does not meet the requirements according to the foam shape parameters output from the foam output manifold, controlling the real-time rotation speed of the motor in the foam generating device according to the required foam shape to adjust the foam dispersion degree includes:

[0131] Obtain the foam dispersion degree in the foam output manifold of the foam generating device provided by the system controller;

[0132] Determine whether the foam dispersion meets the requirements according to the foam dispersion in the foam output manifold; if it does not meet the requirements, determine the real-time speed of the motor after adjustment according to the required foam dispersion to adjust the foam dispersion; wherein, the real-time speed of the adjusted motor is determined by the following formula: D = K * V a , where K is a fixed coefficient determined by the size parameters of the foam generating device; a is an empirical coefficient; D is the foam dispersion; V is the real-time speed of the motor.

[0133] Preferably, when it is determined that the density of the output foam does not meet the requirements according to the real-time density of the foam in the foam output manifold, adjust the control parameters of the control valves of the base liquid input manifold and / or the gas input manifold according to the real-time flow rate of the base liquid in the base liquid input manifold, the real-time flow rate of the gas in the gas input manifold, the real-time density of the foam, and the target density of the foam, so as to adjust the density of the foam output in the foam output pipeline, including:

[0134] Obtain the real-time flow rate of the base liquid in the base liquid input manifold, the real-time flow rate of the gas in the gas input manifold, and the real-time density of the foam in the foam output manifold provided by the system controller;

[0135] Determine whether the density of the foam meets the requirements according to the real-time density of the foam in the foam output manifold; if it does not meet the requirements, determine the adjustment amount of the real-time flow rate of the base liquid in the base liquid input manifold and / or the adjustment amount of the real-time flow rate of the gas in the gas input manifold according to the magnitude relationship between the target density and the real-time density of the foam, the real-time flow rate of the base liquid in the base liquid input manifold, and the real-time flow rate of the gas in the gas input manifold, so as to adjust the density of the foam output in the foam output pipeline.

[0136] For example, in this embodiment, it is necessary to configure 40 cubic meters of foam fluid with a density of 0.85 g / cm 3 The specific operations are as follows:

[0137] First, connect each manifold and the foam generating device, apply a pressure of 1 MPa to the pipelines in the manifold to test the sealing performance of the entire system; connect the manifold system and the foam generating device to the system controller and connect to the control terminal, power on and test, check the data display of the manifold system and the foam generating device, and check whether the opening and closing functions of the electric switch valves are normal; power on the motor, and open the electric control switch valve on the foam output manifold to 100% on the control terminal. Adjust the electric switch valves of the base liquid input manifold and the gas input manifold to 50%, so as to input the foam generating materials, and at the same time start the motor, and adjust the speed to 2000 rpm. At this time, the system has been successfully started. After 5 minutes, the pressure, flow rate, and density indicators have stabilized, and the system production has stabilized, indicating that the system can produce stably.

[0138] At this time, observe the foam density ρ_foam on the human-machine interface. If the density of the foam is 0.85 g / cm3 , there is no need to adjust the valve opening on the human - machine interface of the control terminal. If the foam density is greater than 0.85 g / cm 3 , then reduce the opening of the electric switch valve on the foam base liquid manifold on the human - machine interface. It can be reduced by 10% successively, or reduced according to other thresholds. Provide the control parameter of the control valve input by the user obtained on the control terminal to the system controller, and at the same time observe the density value of the generated foam until the foam density is 0.85 g / cm 3 , and foam with the required density for on - site construction is generated. Correspondingly, the opening value of the switch valve on the gas input manifold can be adjusted to achieve the adjustment of the foam density, or the opening value of the electric switch valve on the foam base liquid manifold and the opening value of the switch valve on the gas input manifold can be adjusted simultaneously to achieve the adjustment of the foam density.

[0139] If you want to adjust the dispersion degree of the foam, you can observe the rotation speed of the motor on the human - machine interface and adjust the dispersion degree of the foam by adjusting the rotation speed of the motor.

[0140] If a large amount of foam is required on - site at this time, according to the density formula ρ_foam=(Q_liquid*ρ_liquid) / (Q_gas + Q_liquid), it can be known that the density of the foam is related to the flow rates of the input base liquid and gas. When the flow rates of the base liquid and gas are increased in equal proportion, the foam density will not change at this time, but the amount of generated foam increases in equal proportion.

[0141] The above - mentioned foam fluid generation method of this embodiment can carry out foam operations according to the foam fluid generation system, can adjust the density and dispersion degree of the generated foam as needed, reduces the intensity of manual labor and operation costs, improves production efficiency and the quality of the produced foam, and finally realizes intelligent operation production.

[0142] The above - mentioned foam fluid generation system can also adjust the generation speed of the foam, realize the rapid generation of foam, and can generate foam with a small diameter and a high content of effective micro - bubbles.

[0143] Based on the same inventive concept, an embodiment of the present invention provides a foam fluid generation device, which can be set in a device capable of processing computer instructions, and its structure is as Figure 5 shown, including:

[0145] The density control module 22 is configured to, when it is determined that the density of the output foam does not meet the requirements according to the real-time density of the foam in the foam output manifold, adjust the control valve control parameters of the base liquid input manifold and / or the gas input manifold according to the real-time flow rate of the base liquid in the base liquid input manifold, the real-time flow rate of the gas in the gas input manifold, the real-time density of the foam, and the target density of the foam, so as to adjust the density of the foam output in the foam output pipeline.
