In view of the limitations that conventional chemical tracers are of few types, toxic and low in detection accuracy and PLT logging technology fails to monitor the produced fluid profile of horizontal wells and highly inclined wells, trace metal tracer was prepared by using non-radioactive trace metal substances that do not exist or exist in very low content in the formation, and its performance was evaluated. Meanwhile, data analysis method was developed with optimized process flow. A systematic technology for monitoring non-radioactive trace metal tracer was developed and applied in the field. The results show that the non-radioactive trace metal tracer had a temperature resistance of 200 ℃ and a salt resistance of 25×104mg/L. It could remain clear in the solutions with pH values of 1 and 14, and would not be adsorbed by clay substances in the reservoir. The detection accuracy was up to 10-14kg/L. The tracer was effective in monitoring the produced liquid profile, analyzing the fracture morphology and evaluating the fracturing effect. This technology was used to monitor the fluid production of a horizontal well in Yanchang Oilfield, and the fracture development was analyzed by the normalized output curve of the tracer, providing technical data for the evaluation of fracturing effect. This technology provides technical support for produced fluid profile monitoring and fracture development evaluation.
