JDV选择性试验仪的研制与应用

DEVELOPMENT AND APPLICATION OF SELECTIVE TRIAL INSTRUMENT JDV

介绍了 JDV选择性试验仪的工作原理与组成、用途以及试验方法。该仪器是有 3个滤口 ,可同时测定高、中、低渗透率 3块岩心 ,能模拟非均质地层中进行增产措施时的进液分布情况 ,进行堵水、调剖和酸化的选堵、转向技术研究。通过室内试验研究了 JHY油溶性树脂暂堵剂的酸化转向效果 ,经现场应用获得成功。

JDV Selective Trial Instrument is introduced for its working principle and constituent, usage and testing method. This device has three filter beds and can be used to measure simultaneously three high, middle and low permeability cores, and can be applied to simulate the entering fluid distribution in heterogeneous formation while stimulating, to study selective plugging and diverting technology in water plugging, profile control and acidizing. A kind of temporary plugging which oil soluble resin JHY was studied with this equipment for the acidizing diversion affect and succeeded in Henan Oilfield.
