Application of Intelligent Cable-laying Composite Coiled Tubing in Oilfield Water Sup-ply Wells
The surface water resources of an oilfield are poor,and the production and domestic water mainly come from water source wells.However,due to the influence of season and groundwater re-source enrichment,the water production of the formation is not stable,the water level cannot be monitored in real time,and deep well pumps are prone to burnout.After the implementation of digital and smart oilfield construction in the oilfield,parameters related to water supply wells cannot be read and accessed,in addition,it is inconvenient to lift and lower the pipe string and power cable in water supply wells.In view of these,the cable-laying composite coiled tubing integrated with power cable and signal cable,and the intelligent control system of the water supply well are developed and applied.It can read the data of downhole dynamic liquid level,outlet pressure,wellhead flow,and monitor the operation status of the deep well pump in real time,and realize intelligent monitoring,remote control,real-time parameter adjustment,slow start and slow stop,frequency conversion operation,dry pumping protection,deep well pump status control and other functions.The intelligent control of the water supply well is realized,and the purpose of energy saving and emission reduction is achieved.
