[0027] Reference Figure 1 This is a schematic diagram of the structure of a downhole micro-logging system according to an embodiment of the present application. The downhole micro-logging system is mainly used to realize dynamic monitoring of downhole data of horizontal wells, so as to obtain downhole temperature parameters, pressure parameters and flow parameters. And the micro-tester can be controlled to automatically return to the wellhead of the horizontal well.

[0028] Specifically, the downhole micro-logging system 100 includes a micro-tester 101, a density reduction module 102 and a density increase module 103. The micro-tester 101 is connected to the density reduction module 102, and the micro-tester 101 is used to dynamically monitor the temperature parameters, pressure parameters and flow parameters corresponding to the horizontal well. The density reduction module 102 is connected to the micro-tester 101 and the density increase module 103, and the density reduction module 102 is used to reduce the overall average density of the downhole micro-logging system 100, wherein the density reduction module 102 is a high-strength, low-density, pressure-resistant shell of the cavity. The density increase module 103 is connected to the density reduction module 102, and the density increase module 103 is used to control the overall average density of the downhole micro-logging system 100, wherein the density increase module 103 is a metal solid that can be dissolved in water.

[0029] In the existing technology, the traditional oil field downhole temperature and pressure testing instruments are large in size, with a length between 0.5m and 1m and a weight between 2kg and 5kg. When conventional instruments are lowered into the well, they need to be controlled by a steel wire test vehicle, a cable test vehicle, and an oil pipe connection instrument. And after the downhole data monitoring work is completed, multiple staff members are required to recover the downhole temperature and pressure testing instruments. Moreover, if there is pressure at the wellhead during the test construction, it is also necessary to use blowout prevention equipment, weighted rods and other tools to cooperate with the construction, which will affect the normal production of the oil well.

[0030] Therefore, in the present application, the density of the produced fluid in the horizontal well and the density of the micro tester 101 are obtained in advance. Then, based on the density of the micro tester 101, the density of the density reduction module 102 is calculated. Among them, the density reduction module 102 is a high-strength, low-density, pressure-resistant shell including a cavity. By calculating the volume of the cavity, the overall density of the micro tester 101 and the density reduction module 102 is less than the density of the produced fluid in the horizontal well, thereby satisfying the condition for the micro tester 101 to automatically return to the wellhead of the horizontal well. Then, based on the overall density of the micro tester 101 and the density reduction module 102, the volume of the density increase module 103 is calculated, so as to control the overall density of the downhole micro logging system 100 to be greater than the density of the produced fluid in the horizontal well, so as to control the downhole micro logging system 100 to be put into the horizontal well.

[0031] By putting the downhole micro-logging system 100 into the horizontal well, the micro-tester 101 is controlled to monitor the temperature parameters, pressure parameters and flow parameters of the downhole in real time. After the data monitoring is realized, the density increasing module 103 is controlled to be separated from the density decreasing module 102, so as to control the micro-tester 101 to return to the wellhead of the horizontal well based on the overall density of the micro-tester 101 and the density decreasing module 102. Among them, the temperature sensor, the acceleration sensor and the noise sensor are integrated in the micro-tester 101, so that the volume and weight of the micro-tester 101 can be reduced to the greatest extent, thereby reducing the volume and weight of the downhole micro-logging system 100. In addition, since the downhole micro-logging system 100 includes the density decreasing module 102 and the density increasing module 103. Based on the density adjustment of the density decreasing module 102 and the density increasing module 103, the micro-tester 101 can be controlled to automatically return to the wellhead of the horizontal well, thereby simplifying the placement process and recovery process of the micro-tester 101, reducing the cost of downhole data monitoring, and realizing the normal production of the oil well.

[0032] Furthermore, the micro tester 101 includes a pressure sensor 104: the pressure sensor 104 is disposed directly above the inside of the micro tester 101, and the pressure sensor 104 is used to obtain a pressure signal in the horizontal well.

[0033] Furthermore, the micro tester 101 includes a pressure conducting hole 105 : the pressure conducting hole 105 is arranged directly above the pressure sensor 104 , and the pressure conducting hole 105 is used to conduct the pressure sensor 104 .

[0034] In the present application, in order to accurately obtain the pressure signal downhole, a pressure conducting hole 105 is provided directly above the pressure sensor 104. Through the pressure conducting hole 105, the pressure sensor 104 is connected, thereby realizing the contact between the pressure sensor 104 and the external environment of the micro tester 101, so as to accurately obtain the pressure signal in the horizontal well.

[0035] Furthermore, the micro tester 101 includes a data acquisition processing module (not shown in Figure 1 As shown in the figure): the data acquisition and processing module is connected to the pressure sensor 104 through wiring, and the data acquisition and processing module is used to convert the pressure signal obtained by the pressure sensor 104 into a pressure parameter, and to convert the temperature signal obtained by the temperature sensor into a temperature parameter, and to convert the speed signal obtained by the acceleration sensor and the liquid production information obtained by the noise sensor into a flow parameter, wherein the temperature sensor, the acceleration sensor and the noise sensor are arranged in the data acquisition and processing module.

[0036] In the present application, by setting the data acquisition and processing module of the highly integrated temperature sensor, acceleration sensor and noise sensor in the micro tester 101, the overall volume and weight of the micro tester 101 are greatly reduced, thereby simplifying the placement process and recovery process of the micro tester 101, thereby reducing the cost of downhole data monitoring and ensuring the normal production of the oil well.

[0037] Furthermore, the data acquisition processing module includes a photodiode (not shown in Figure 1 ): A photodiode is arranged in a switch circuit in the data acquisition and processing module, and the photodiode is used to control the conduction of the switch circuit and control the operation mode of the data acquisition and processing module, and the operation mode includes an acquisition mode and a Bluetooth communication mode.

[0038] In the present application, since the weight and volume of the micro tester 101 are greatly reduced, the volume of the power module 108 in the micro tester 101 will also be reduced, resulting in a reduction in the amount of electricity in the power module 108. Based on this, it is necessary to reasonably control the discharge amount of the power module 108 in the micro tester 101.

[0039] Specifically, a photodiode is set in the switch circuit in the data acquisition and processing module to control the conduction of the switch circuit. That is, when the photodiode is irradiated by light, the photodiode is turned on, thereby controlling the operation of the data acquisition and processing module. At the same time, according to the irradiation time of the light on the photodiode, the operation mode of the data acquisition and processing module can be controlled, and the operation mode includes the acquisition mode and the Bluetooth communication mode. Among them, if the irradiation time is less than the preset time, the operation mode of the data acquisition and processing module is controlled to be the acquisition mode. If the irradiation time is greater than the preset time, the operation mode of the data acquisition and processing module is controlled to be the Bluetooth communication mode. The Bluetooth communication mode is to send the calculated downhole temperature parameters, pressure parameters and flow parameters to the receiving module on the ground through the Bluetooth module, so that various parameters in the downhole can be monitored and analyzed in real time.

[0040] Furthermore, the downhole micro logging system 100 also includes an adhesion surface 106: the adhesion surface 106 is arranged between the density reduction module 102 and the density increase module 103, the adhesion surface 106 is a soluble metal ring, and the adhesion surface 106 is used to connect the density reduction module 102 and the density increase module 103, and control the separation time of the density reduction module 102 and the density increase module 103.

[0041] In the present application, in order to realize the timed control of the micro tester 101 to automatically return to the wellhead of the horizontal well, an adhesion surface 106 is set between the density reduction module 102 and the density increase module 103, wherein the adhesion surface 106 is a soluble metal ring. By controlling the radius of the soluble metal ring, the dissolution time of the soluble metal ring can be controlled, thereby controlling the separation time between the density reduction module 102 and the density increase module 103. When the density reduction module 102 and the density increase module 103 are separated, the overall density of the downhole micro logging system 100 is reduced. Based on the density of the downhole production fluid of the horizontal well and the overall density of the downhole micro logging system 100, the micro tester 101 will automatically return to the wellhead of the horizontal well to realize the timed recovery of the micro tester 101.

[0042] Furthermore, the micro tester 101 includes a high temperature resistant light-transmitting housing 107: the high temperature resistant transparent housing is arranged outside the micro tester 101, and the high temperature resistant light-transmitting housing 107 is used to control the conduction efficiency of the photodiode.

[0043] In the present application, before the micro tester 101 is put into the horizontal well, it is necessary to irradiate the micro tester 101 with light. Specifically, due to the small size and weight of the micro tester 101, it is impossible to conveniently control the operation of the power module 108. At the same time, since the power of the power module 108 in the micro tester 101 is too small, it is necessary to reasonably use the power of the power module 108. Therefore, by irradiating the micro tester 101 with light, the conduction of the photodiode can be achieved, and the conduction efficiency of the photodiode can be controlled, so that the power module 108 can be conveniently controlled to operate, and the power of the power module 108 can be reasonably used to improve the endurance of the micro tester 101.

[0044] Furthermore, the system also includes a power module 108 : the power module 108 is arranged at the bottom of the micro tester 101 , and the power module 108 is used to supply power to the devices in the downhole micro logging system 100 .

[0045] It can be seen from the above technical solution that the present application has at least the following advantages and positive effects:

[0046] In the present application, a downhole micro-logging system is constructed by sequentially bonding a micro-tester, a density reduction module, and a density increase module. In the micro-tester, a temperature sensor, an acceleration sensor, and a noise sensor are highly integrated, so that the volume and weight of the micro-tester can be reduced to the greatest extent, thereby reducing the volume and weight of the downhole micro-logging system.

[0047] Based on the pre-acquired density of the downhole produced fluid of the horizontal well, the corresponding volumes and densities of the density reduction module and the density increase module are determined, so that the density of the downhole micro-logging system before the separation of the density reduction module and the density increase module is greater than the density of the downhole produced fluid of the horizontal well, and the density of the downhole micro-logging system after the separation of the density reduction module and the density increase module is less than the density of the downhole produced fluid of the horizontal well, thereby realizing the data monitoring function and automatic recovery function of the micro-tester.

[0048] Therefore, the present application can realize dynamic monitoring of downhole data of horizontal wells, and control the micro-tester to automatically return to the wellhead of the horizontal well, thereby reducing the cost of downhole monitoring of horizontal wells and ensuring the normal operation of the oil wells.
