摘    要:为了搞清七个泉油田一区块七4—7注水井组油水井连通情况,找出井间存在的大孔道或高渗层,弄清油藏平面与纵向上的非均质性及剩余油分布情况,2003年9月在该井组进行同位素示踪剂井间监测。监测的方法是在水井中注入一种水溶性示踪剂,在周围监测井中取水样,分析水样中示踪刑的浓度,应用示踪剂软件解释技术进行分析。监测结果表明:注入水的方向性较明显,主要驱向七5—8等5口井,水推速度整体较均衡,注水控制效果较好,七4—7水井与七4—6、七5-6井井间储层物性较差,监测井之间的层内非均质程度较大。

关 键 词:青海油田  同位素  示踪剂  监测技术

Application of Isotopic Tracer Detection Technology anong Wells to Qigequan Oilfields
Abstract:Detection of isotopic tracer technology was conducted in wells Qi4-7 of District No.l in Qigequan oilfield in September 2003, in order to know the connection between wells in this group, to find the large passage or high-permeability layer, and to maker clear the anisotropy of horizontal and vertical level of oil reserves. The detecting method is to inject one kind of water-soluble tracer first, then to get water sample from surrounding detected well and analyze the tracer concentration in the sample hy using the tracer software explanation technique. And the detecting results show that the direction of injected water is clearly toward wells Qi5-8, with the even speed of water moving and better effect of water injection controlling; but that there are poor property of reserves between water wells Qi4-7 and wells Qi4-6, Qi5 6, and high anisotropy among detected walls.
Keywords:Qinghai oilfields  isotopic  tracer  detection technology
