The present invention provides a side-drilling well completion device and method that can be selected without drilling and grinding. The side-drilling well completion device that can be selected without drilling and grinding includes a positioning and straightening device and a removable window opening device that can be selected without drilling and grinding. The positioning and straightening device is located in the wellbore to locate the exact position of the side-drilling well section and straighten the wellbore and casing. The removable window opening device that can be selected without drilling and grinding is located at the casing of the side-drilling oil layer part that needs to be opened. When drilling into the side-drilling well section that needs to branch, the removable window opening device that can be selected without drilling and grinding is opened by remote control to directly open the casing section that needs to be opened by side-drilling, without drilling and grinding the casing at the window opening part. The side-drilling well completion device and method that can be selected without drilling and grinding greatly reduce the drilling cost of the side-drilling well, improve the drilling efficiency, shorten the drilling cycle of the actual side-drilling well and the side-drilling horizontal well, and improve the investment efficiency and return rate. The labor intensity of the operators is reduced, and the operation time and cost are reduced.

The present invention relates to a method for monitoring the operation of a pumping station (1), wherein the pumping station (1) includes: a storage tank (6) for temporarily storing liquid; an inlet (7) for liquid inflow; an outlet (8); and at least one pump (2) configured to deliver liquid out of the storage tank (6) through the outlet (8). The method is characterized by the following steps: monitoring the inflow of liquid into the storage tank (6) for at least a portion of a predetermined time period (T) and determining inflow data (IN) representing the amount of liquid flowing into the storage tank (6) of the pumping station (1) during the predetermined time period (T); determining pumping station maximum capacity data (PSMC) representing the maximum capacity of liquid pumped from the storage tank of the pumping station (1) during the predetermined time period (T); and, for the predetermined time period, using the general formula PSCU based on the determined values ​​of the inflow data (IN) and the pumping station maximum capacity data (PSMC). M (%) = 100 * IN / PSMC to determine the instantaneous pump station capacity utilization rate (PSCU) M ); and based on at least one instantaneous pump station capacity utilization rate (PSCU) M The value is used to determine the typical pump station capacity utilization rate (PSCU) of pump station (1). T The typical pump station capacity utilization rate (PSCU) T This indicates the capacity utilization rate of the pumping station over a period of time.
