摘　　要：安塞油田长7页岩油层非均质强,在水平井分段体积压裂后准确了解各段产液、产油贡献率对于油藏下步开发部署具有[1]重要意义。ZPX井在体积压裂过程中把示踪剂通过量子点技术标记在聚合物中,聚合物吸附在支撑剂表面形成聚合物涂层。后续生产过程中通过流体中所含示踪剂进行分类、化验分析和计算,得到各层段体积改造后的产液贡献率,为安塞油田页岩油开发体积压裂优化设计和产能评价提供了新的方法。Accurate exploring the fluid and oil production contribution rates of the Chang 7 shale reservoir,which with strong heterogeneity in Ansai Oilfield,plays a significant role in its development and deployment after segmented volume fracturing of horizontal wells.During the volume fracturing of the ZPX well,the tracer was labeled in the polymer through quantum dot technology to form a polymer coating by adsorbing on the surface of the proppant.In the follow-up production,the tracer contained in the fluid is classified,lab-analyzed and calculated to obtain the fluid contribution rate after volume modification of each segment,which provides a new method for volume fracturing optimization design and productivity evaluation of shale oil development in Ansai Oilfield.
