分层测试技术在辽河油田的发展与应用

Layer-separated Testing Technology and Its Application to Liaohe Oilfield

分层测试是油气井笼统测试的细化与发展,包括分层压力、温度测试和产液状况的取样与分析,适应了油田进入开发中后期阶段对油藏纵向各层进行精细描述的需求。经过多年现场应用,该技术逐步发展完善,由常规的分层压力温度测试技术发展到分采、分测、分层取样技术。介绍了分层测试技术的发展历程、工艺原理及现场应用,依据需测取的井的层数、厚度、生产状况等条件选用不同的测试方式,如管柱式、智能式、泵抽式等,3种测试方式可互为补充。

Classified as oil- and gas- well testing, the layerseparated testing contains to analyze both layer-separated pressure and production fluid, and test temperature. To use this testing technology may carry out a fine description on every layer in vertical during middle to later development stages. After in-situ application, the technology has been well developed and comprehensive.Moreover, it has developed from conventional layer-separated pressure testing to multiple technologies of layer-separated production,testing, and sampling. This paper illustrates its principle, development, and application. However, different testing ways may be used for various conditions of tested wells, such as layer number, thickness, and production status. There are three ways including pipestring testing, intelligent testing, and pumped testing and also complementary.
