Title: Polymer Flooding Effect Tracking and Monitoring Fingerprint Technology for the Second Class Reservoir
Abstract: The tracking and monitoring of polymer flooding effect is an important basis for fine adjustment of polymer flooding to improve oil recovery. Four oil Wells were selected as stratified crude oil sampling and main Wells to monitor the stratified productivity and oil displacement effect of 38 oil Wells in the study area of saertu oilfield according to the connectivity of the cluster flooding oil Wells in the second class. Using layered testing technology for samples of main shaft stratification of crude oil and production, through the feasibility experiment to determine polymer does not affect the crude oil hydrocarbon fingerprint characteristics, chromatographic quantitative detection by internal standard method of crude oil, mix proportioning and selection characteristic hydrocarbon fingerprint parameters, nonlinear mathematical simulation calculation method, chemical model is set up and monitor the template, implements 6 laminated failure of layered polymer flooding monitoring capacity, established the hydrocarbon fingerprint experiment technology of crude oil are monitoring the effectiveness of the polymer flooding oil well layered capacity, compared with the layered testing results on the absolute deviation is not more than 4.3%, good agreement with the reservoir dynamic and static data, and the thicker and middle and low water-flooded oil layers in the second type of oil layers are used first with high degree of operation and obvious effect, which provides an effective means for solving the difficult problem of tracking and monitoring the layered oil displacement effect in polymer flooding oil fields.
