摘要

摘要: 以镧系金属氯化物、EDTA·2Na、DTPA、氢氧化钠等为原料，合成了16种示踪剂产品。通过电感耦合等离子体发射光谱对各元素检出限、元素间干扰性等进行测试，得出16种示踪剂检出限在10～80 mg/m³之间，且互相之间无干扰。该技术成功应用于苏里格地区水平井压后分析中，通过返排液中的示踪剂返排时间-浓度关系、引入校正因子及各层段返排液量半定量计算，完成该井各层段产液情况分析，经分析该井第7段返排液量最大，经拟合计算返排出该层段所用示踪剂元素约49.875 g，返出液体约145.16 m³。

Abstract: 16 tracers have been developed using lanthanide series metals, EDTA·2Na, DTPA and NaOH etc. The tracers were tested with ICP-AES for the detection limit of each element and the interference among the elements. It was concluded that the detection limits of the 16 tracers are between 10 mg/m³ and 80 mg/m³, and no interference was found among these elements. The tracers have been successfully used in the analysis of horizontal well fracturing in Sulige. The analysis was done by examining the relationship between the time required for the tracers to flow back and the concentration of the tracers, by introducing correction factor and by semiquantitatively calculating the volume of flowback fluid from each zone. It was found in the analysis that the seventh segment of the pay zone had the highest rate of flowback. The total amount of tracers flowed back from this segment, by data fitting, was about 49.875 g, and the volume of the flowback fluid was 145.16 m³.
