Production Profile Logging Technologies in Daqing Oilfield

The primary industrialized technologies and tools of production profile logging(PPL) in Daqing Oilfield are summarized,of which the followings are described in detail: turbine flowmeter optimize-designed for and calibrated discretely in low flow rate range so that adapted for application to low fluid production measurement,flowing water cut meter with capacitance sensor,and low fluid production logging tool with separated multi-electrode by which the very small flow rate can be measured with better oil-water distinguishing capacity;impedance/conductance water cut meter suitable for high-water-cut production profile logging;coaxial electromagnetic wave phase water cut meter which has excellent performance for very high or very low water cut measurement;3-phase flow logging technique based mainly on 3-phase hold up and average density measurement applying low energy photon absorption effect;5-parameter combination logging technique;production profile continuous well logging technology;fluid sampling technology purpose-designed for polymer flooding;as well as the optimized production profile interpretation technique for 2-phase fluid logging data in which the error propagation functions are established.New technologies being researched are also introduced briefly.
