摘要
从注水井压力降落测试 (即注水井落差测试 )的压力特性出发 ,对注水井的测试资料 (包括压力降落曲线及压力指数PI值在关井 90min时所得的PI(90 )值 )进行分析、研究 ,拓展了注水井压降资料的应用领域 ,将这些认识应用于喇嘛甸油田三次采油试验的选井、选层及效果评价等方面 ,效果显著。粘土调剖试验说明 ,引入PI(90 )
Proceeded from pressure behavior of injection well pressure draw-down test (i. e. injection well drop test), this paper analyzes and studies the injection well test data(including pressure draw-down curve and PI(90) value obtained from pressure index at 90 min after well shut-in), opening up the application field of injection well draw-down data. This understanding has been used in well selection, formation selection of tertiary recovery test of Lamadian Oilfield and evaluation of test results etc. With remarkable effect, the clay profile control test indicates that introduction of PI correction formula is conformable to reality.
