示踪法井漏位置测定技术

Locating the Lost Circulation Position Using Tracing Method

根据井漏将引起钻井液循环时间变化及钻井液出口流量变化的原理 ,提出了示踪剂漏层位置测定方法 ,建立了漏层位置计算模型 ,编制了示踪剂法漏层位置计算软件。在新疆油田的现场应用表明 ,该方法检测精度高 。

The method using tracers to locate lost circulation positions according to the variation of drilling fluid circulating time and outlet pump rate owing to lost circulation is put forward in this paper. The model used to calculate the lost circulation positions is founded and the related software is developed. The field applications in Xinjiang Oilfield show that the method is of high accuracy and wide adaptability.
