Description

Technical Field

[0001] This invention belongs to the field of oilfield stratified water injection technology, and in particular relates to a stratified water injection integrated data acquisition system and its remote monitoring method. Background Technology

[0002] The cabled intelligent injection process consists of two parts: the downhole intelligent injection process tubing and the surface control system. The surface control system comprises a surface explosion-proof controller, a host computer, and measurement and adjustment software. The surface explosion-proof controller is usually installed near the wellhead tree. Due to space constraints on offshore platforms, to save space, the conventional surface explosion-proof controller adopts a one-to-many connection method, that is, one surface controller can connect to 4-7 wells. It uses a polling mode to switch power supply / communication between different wells and connects to the host computer in half-duplex mode via an RS485 communication cable. Under the control of the measurement and adjustment software, it completes the intelligent control of multiple injection wells.

[0003] With the large-scale application of intelligent injection wells and the need for remote real-time monitoring, the platform needs to install multiple ground controllers, which increases the equipment's control over the platform and the workload of platform personnel in managing the equipment. At the same time, the existing ground controller and monitoring system architecture can no longer meet the requirements of multi-user, concurrent access, real-time monitoring and control. Summary of the Invention

[0004] In view of this, the present invention aims to propose an integrated data acquisition system for injection wells and its remote monitoring method that can reduce platform space occupation and facilitate centralized equipment management. It can meet the needs of remote real-time monitoring for multiple users and parallel access, and realize remote intelligent control of injection wells.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A distributed integrated data acquisition system includes an integrated control cabinet body and a first support installed inside the integrated control cabinet body. The first support divides the internal space of the integrated control cabinet body into a switch room, a display and control room, an acquisition and monitoring room, and a wiring room. Multiple drawer units are installed on the first support. Multiple plug-in boards and terminal blocks are installed in the wiring room. One end of the terminal block is connected to a two-pin socket of the plug-in board, and the other end is electrically connected to a junction box. Each plug-in board corresponds to the rear end face of a drawer unit. A plug connector is provided at the rear end of the drawer body. The plug connector and the plug socket provided on the plug-in board cooperate to realize pull-out power supply and power disconnection. A cooling fan is installed on the top of the integrated control cabinet body.

[0006] Furthermore, the drawer unit includes a drawer body, inside which a second support is provided. An intelligent dispensing and control circuit is mounted on the second support. A voltmeter, an ammeter, a pull-out handle, an adjustment knob, a first power indicator light, a power switch button, a debugging socket, and a label are mounted on the front surface of the drawer body. The voltmeter, ammeter, adjustment knob, first power indicator light, power switch button, and debugging socket are electrically connected to the intelligent dispensing and control circuit. Guide bosses are mounted on both sides of the drawer body. Two connectors are mounted on the rear surface of the drawer body, including a three-pin plug and a two-pin plug. The three-pin plug and the two-pin plug are electrically connected to the intelligent dispensing and control circuit.

[0007] Furthermore, a concave guide rail is provided at the position where the first bracket connects with the drawer unit. The concave guide rail cooperates with the guide bosses provided on both sides of the drawer unit to realize the pulling guide and support fixation of the drawer unit.

[0008] Furthermore, the switch room is equipped with a main power switch, a fuse, a second power indicator light, and branch power switches. The main power switch and the fuse are connected. The end of the fuse away from the main power switch branches out into multiple branches, and each branch is connected in sequence to a second power indicator light and a branch power switch.

[0009] Furthermore, each connector board is equipped with two connectors, including a three-pin socket and a two-pin socket. The three-pin socket is electrically connected to the power switch, and the two-pin socket is electrically connected to one end of the terminal block. The two connectors of the drawer body cooperate with the two connectors of the connector board to realize the pull-out power supply and power disconnection.

[0010] Furthermore, the display and control room is equipped with a monitor, keyboard and mouse, and the acquisition and monitoring room is equipped with an edge computing unit, network gateway, firewall, switch and gateway.

[0011] The monitor, keyboard, and mouse are connected to the edge integrated machine. The switch has multiple interfaces, and each drawer unit is equipped with a gateway. One end of the gateway is electrically connected to the intelligent injection monitoring and control circuit via an RS485 interface, and the other end is connected to the switch via an Ethernet interface. The edge integrated machine is equipped with dual network cards. One network card is connected to the switch network and runs multi-threaded data acquisition and monitoring software to realize real-time data acquisition, storage, and monitoring of multiple intelligent injection wells. The other network card is connected to the office network and the land cloud server via a network gateway and firewall.

[0012] Furthermore, the integrated control cabinet body has heat dissipation holes on its side panel.

[0013] A remote monitoring method for integrated data acquisition using the above-mentioned acquisition system includes the following steps:

[0014] Step 1: Lay a ground communication cable from the integrated data acquisition system for injection sub-injection to the downhole steel cable at the treehead end of the intelligent injection well;

[0015] Step 2: Connect one end of the ground communication cable to the underground steel pipe cable through the wellhead junction box and seal the joint. The ground communication cable is double-core. One core is connected to the core of the steel pipe cable and is defined as the positive pole. The other core is connected to the outer steel pipe layer of the steel pipe cable and is defined as the negative pole.

[0016] Step 3: Connect the other end of the ground communication cable to the terminal block installed in the wiring room;

[0017] Step 4: Connect the other end of the terminal block to the two-pin socket cable of the connector board;

[0018] Step 5: Connect the three-pin socket of the plug board to the power switch cable in the switch compartment;

[0019] Step 6: Connect the serial RS485 communication port of the intelligent injection monitoring and control circuit to the RS485 serial communication port of the gateway via cable.

[0020] Step 7: Configure the IP address and port for the gateway, and connect the Ethernet port of the gateway to the port of the switch with a network cable;

[0021] Step 8: The edge all-in-one machine is equipped with dual network cards. Connect one network port to the switch with a network cable, and connect the other network port to the network gateway and firewall with a network cable to connect to the office network.

[0022] Step 9: Repeat steps 1 through 7 to connect all intelligent injection wells on the platform to the platform's local area network and assign an independent IP address to each intelligent injection well.

[0023] Furthermore, the intelligent injection measurement and control circuit communicates with the edge integrated machine using the Modbus TCP protocol. Multi-threaded real-time data acquisition and remote monitoring software runs on the edge integrated machine, enabling real-time parallel communication with multiple intelligent injection wells. The collected downhole injection real-time data from the intelligent injection wells is transmitted to the land cloud server via a remote communication protocol. The machine also receives encrypted remote control commands for the injection wells from the cloud, parses the commands, and sends them to the intelligent injection measurement and control circuit at a specific IP address. The intelligent injection measurement and control circuit then controls the switching of the downhole intelligent injection tool according to the control commands, thereby achieving remote real-time monitoring of the intelligent injection wells.

[0024] Compared with existing technologies, the integrated data acquisition system and remote monitoring method for injection described in this invention have the following advantages:

[0025] (1) The ground control cabinet adopts an integrated structural design, and one control cabinet can centrally manage multiple intelligent injection wells;

[0026] (2) Each well is equipped with an independent power supply switch, a pull-out unit and a measurement and adjustment circuit, which facilitates on-site troubleshooting, equipment repair and maintenance;

[0027] (3) Each well is assigned an IP address and the Modbus TCP communication protocol is adopted, which enables multi-user, concurrent remote real-time monitoring of multiple intelligent injection wells. This effectively solves the problems of poor real-time performance and inability to run multiple wells simultaneously in conventional ground control cabinet polling and monitoring of multiple wells. At the same time, it avoids the impact of frequent power outages between wells on the electronic components of the downhole intelligent injection tool and extends the service life of the tool.
