Measurement characteristics of electromagnetic flowmeter in polymer injection well

Facing the problem of short effective time of hydraulic fracturing and chemical broken down in polymer injection wells,this paper analyzes the geologic status and dynamic and static data of 92 chemical broken down wells operated in 2000 and 2001 in 10 polymer flooded blocks, constructs a set of technique for diagnosis and stimulation optimization for polymer injection wells plug.

In many viscous oil wells and polymer injection wells,because of viscous oil and heavy load,the crank-balanced unit used is lacking balance and its effect is poor with low balance rate,thus energy consumption is raised.

Numerical simulation of downhole temperature distribution in polymer injection well;

Since viscosity and stability of polymer are greatly affected by temperature,it is important to analyze influence factors of temperature distribution in polymer injection wells for improving polymer injection scheme and studying oil displacement effect.

According to the actual situation of small-diameter oil-stratified injection wells and small-size diameter gamma ray tool in Lamadian oil field,this paper proposes a supplementary testing methods by memory type flowmeter and gives some views on the separate zone polymer injection well logging technology with small-size diameter in Lamadian oil field and those of data interpretation.
