Abstract

The smart remote testing and regulating separate injection technology is developed in light of the problem of unable to satisfy the requirement of refined zonal water injection due to failing to adaptively control the volume of injection per the variation of formation pressure for fixed nozzle injection allocation model adopted by bridge eccentric separate injection technology as well as problems of large size of matching testing and regulating equipment & tools, retrieving testing & regulating approaches constrained by well deviation and injection water quality plus pressure unable to be accurately measured due to high testing and regulating frequencies etc. The remote zonal water volume control, downhole constant flow injection and real time monitoring of the wellhead flow rate, pressure and temperatures are realized by the synergy of downhole water distributor, surface control and data acquisition unit as well as the remote desktop communication unit. In the mean time, the downhole zonal flow rate and pressure data are transmitted to the control room in remote manner to realize the wellhead unmanned operation. It is indicated by the field experiment that this technology features simple process string, reliable and safe construction and testing & regulating, sound adaptability for highly deviated and horizontal wells, which lays solid foundation for the refined low cost lean management in terms of zonal water injection wells in high water cut oilfields.
