DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] like Figure 1 As shown, the drilling sidetracking parameter monitoring system S comprises a power module S1, a relay isolation module S2, and a PLC module S3. The relay isolation module S2 is located between the power module S1 and the PLC module S3.

[0023] like Figure 2 and Figure 3 As shown, the power module S1 includes a main switch S11, an electrical fuse S12 and a rectifier S13.

[0024] like Figure 4 As shown, the relay isolation module S2 includes a first signal isolator S21 and a second signal isolator S22. The first signal isolator S21 is electrically connected to the first relay KA1, and the second signal isolator S22 is electrically connected to the second relay KA2. The first relay KA1 is connected to the alarm bell output signal, and the second relay KA2 is connected to the hydraulic station operation signal.

[0025] like Figure 5 As shown, the PLC module S3 includes a PLC main body S31 and a PLC expansion module S32, the X0 pin of the PLC main body S31 is connected to the hydraulic station operation signal, the X1 pin of the PLC main body S31 is connected to the internal blowout preventer status signal, the X2 pin of the PLC main body S31 is connected to the alarm bell cancellation signal, and the YO pin of the PLC main body S31 is connected to the alarm bell output signal. The PLC expansion module S32 converts the input top drive speed analog input signal, top drive torque analog input signal and riser pressure analog input signal into digital signals and outputs them to the relay isolation module S2.

[0026] In addition, the model of the PLC main body S31 is XD5E-24T-EPLC, and the model of the PLC expansion module S32 is XD-E4AD.

[0027] The working mode of the drilling sidetracking parameter monitoring system is described below.

[0028] In the power module S1, the main power supply is a normal AC circuit, and the main switch S11 is connected to an electrical fuse S12, the rated current of which is 16A and the model is type C. The electrical fuse S12 provides overload and short circuit protection for the overall circuit of the system, and then directly powers the system through the rectifier S13.

[0029] The drilling sidetracking parameter monitoring system uses the first relay KA1 to control the alarm bell. The PLC module S3 determines whether the received parameters are out of limit according to the quality of each parameter, and sends an alarm bell output signal when the limit is exceeded. The alarm bell output signal turns on the alarm bell output signal through the first relay KA1, and the alarm bell realizes the parameter over-limit alarm function.

[0030] In addition, the drilling sidetracking parameter monitoring system uses the second relay KA2 to identify the operation status of the hydraulic station. The 380V circuit is connected, the hydraulic station is started, and the hydraulic station operation signal is turned on through the second relay KA2. Then, the hydraulic station operation signal is input into the PLC body S31, and the PLC body S31 processes the hydraulic station operation signal according to the preset program, obtains the operation status of the hydraulic station and displays it on the human-machine interface.

[0031] In addition, a first signal isolator S21 and a second signal isolator S22 are added to the hydraulic station operation signal to prevent the two signals from interfering with each other, thereby enhancing the stability, safety and reliability of the system.

[0032] The system has a simple structure, convenient operation, easy maintenance, accurate data, and controllable costs, which meets the needs of side drilling on-site construction. After the system is installed, during side drilling operations, the driller can obtain the key parameters of the drilling process in real time, which provides a more intuitive control over the construction process. At the same time, the system's early warning function can promptly alert possible safety accidents during the construction process, which can directly and effectively improve the safety level of the operation.

[0033] Without limitation to this, any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope defined in the claims.
