为了提高高含水期油田调剖堵水的效果 ,开发了注水井压力指数决策理论 ,并研制了ZY PI1注水井压降测试仪。该仪器能快速、准确地完成对注水井压力指数值的采集和处理 ,为注水井调剖提供可靠的依据。介绍了ZY PI1压降测试仪的测量原理、仪器结构、性能及用途。 1998年和 1999年在濮城油田应用该测试仪分别对 2 0 0多口井进行调剖取得明显效果。应用结果表明 ,该仪器操作简单 ,性能可靠 ,测试数据精确 ,具有较好的应用价值。
In order to improve the effect of profile control and water plugging in high water cut oil fields, a decision theory of pressure well in water injection wells was developed and a ZY PI1 injection well pressure drop tester was developed. The instrument can quickly and accurately complete the injection well pressure index value acquisition and processing, providing a reliable basis for injection well profile control. Introduced the ZY PI1 pressure drop tester measuring principle, instrument structure, performance and use. In 1998 and 1999 in Pucheng Oilfield, the tester was applied to profile more than 200 wells and achieved significant results. Application results show that the instrument is simple, reliable, accurate test data, and has good application value.
