... on line by instrument and then the nozzle can also keep current flowrate constant at that opening position. In this paper, a downhole constant flow nozzle in waterflooding wells is introduced. A constant nozzle is placed in each layer permanently. The nozzle has two chokes. One is used to adjust flowrate...

... an online monitoring and automatic control technology. A instrument was used to realize zonal polymer measurement and adjustment. There is no need for downhole fishing tool. Considering viscosity decrease control, a downhole streamline slot adjustable choke was development. The lab test indicated...

... efficiently and accurately with low cost and low risk. The system is composed of downhole bridge concentric regulator, downhole control instrument and surface control equipment. It can obtain multiple downhole critical parameters on line such as layer flow rate, tubing pressure, formation pressure...

...Control of the neutron emission Abstract Combined with other measurements, neutron porosity tool provide basic and important parameters for real-time formation evaluation and geosteering. In earlier neutron porosity LWD systems, the porosity instruments containe an isotopic chemical source...

... technology is required. The paper proposes a cable-controlled separate-layer production technology. The cable-controlled separate-layer production system consists of adjustable production regulator, testing and adjusting instrument, ground controller, and some matching tools. In the operation process...

... regulator is used. Test tolerance may reach 30% under this method for low flowrate test which result in poor accuracy. To improve low flowrate test accuracy, the method of collection flowrate test based on electromagnetic flowmeter was adopted. This paper designed a dowhnole instrument based...
