南海东部深水油田水平井产出剖面示踪剂监测技术及应用

南海东部深水油田产量测试及水平井产出剖面监测无法有效实施,利用Noyes–Whitney和Higuchi缓释机理制作缓释型油溶性和水溶性示踪剂,设计出适宜水平井的示踪剂工艺管柱,形成了一整套取样及解释方法,并在国内首次试验成功。技术测试过程无需动用管柱,可实现长期安全监测,克服了目前常用水平井生产测井操作复杂、风险高等问题,解决了深水油田产量测试及水平井产出剖面测井难题。

Tracer monitoring technique of production profile for horizontal wells and its application in deep water oilfield in the eastern South China sea

In view of the problem that the production testing and the production profile monitoring for horizontal wells in deep water oilfield in the eastern South China sea cannot be implemented effectively, by using the mechanism of Noyes-Whitney and Higuchi, the oil-soluble and water-soluble tracers were prepared, the tracer string suitable for horizontal wells has been designed, and a set of sampling and interpretation methods have been developed, which was the first successful trial in the country. The process of technical testing does not require the use of pipe string and can realize long-term safety monitoring, which solves the problems of complicated operation and high risk in production logging for common horizontal wells, and overcomes the difficulties in production testing and production profile logging for horizontal wells in deep water oilfield.
