| Currently,the vast majority of the wells in oilfields are water injection wells and polymer injection wells,and the wells adopt the processes of general injection and stratified injection.Injection profile logging data provides evidence for the dynamic monitoring of a single well injection,revealing contradiction of the interlayer and the layers and adjusting injection profile,such as stratified injection allocation profile,water shutoff profile,acidizing,fracturing,etc.as well for the injection relationship adjustment of the group and region.Through the research on the injection profile and logging and comparison of the underground dynamic and static data,adjacent wells production profile can be learnt indirectly,and important logging information is provided to determine a comprehensive adjustment program,and ultimately the recovery is improved.Firstly,the ground and downhole instruments are calibrated.The calibration devices are used to calibrate for the parameters like temperature,pressure,ultrasonic flow,electromagnetic flow before the equipments are qualified to go down.The debugging of the ground instruments makes the signal can be accurate and stable transmission to the ground by cables.Some wells from No.2 oilfield that have similarity in pressure,flow rate and water accepting layer are picked out to perform isotope logging,relating flow rate logging,pulse oxygen activation logging,electromagnetic flow logging projects by using Exceed,the data is interpreted with software smart 2003,and the measured data is used to analyze the application effect of these profile logging methods in No.2 oilfield. |
