对低渗油藏进行压裂改造时，纵向上砂砾岩大厚层的起裂位置、滩坝砂薄互层支撑剂的铺置往往难以准确获得。示踪陶粒技术将非放射性陶粒加入压裂裂缝中，从而改变中子测井的响应，对比压裂前后中子测井俘获截面响应，就可以直观掌握裂缝起裂位置和支撑裂缝高度；该技术可操作性强、解释精度高，对于获取压裂裂缝形态、陶粒铺置情况及压裂改造效果评价起到重要作用。

It is very difficult to accurately get the vertical fracture initiation position of thick bed in glutenite reservoir and the vertical proppant disposal of beach bar thin interbed reservoir. Tracing proppant technology can change neutron logging response by appending nonradioactive proppant into artificial fracture in hydraulic fracturing, which can intuitively get fracture initiation position and fracture height by comparing the capture cross section response of neutron logging before and after fracturing. This technology has strong maneuverability and high interpretation accuracy, which plays an important role in getting fracture shape, proppant disposal and evaluating stimulation effect.
