应用注水剖面流量资料求取遇阻层定量参数解释方法

The Interpretation Method to Obtain Quantitative Parameter of Unknown-formation in Separate Injection Well

为解决分层配注井中同位素注水剖面测井时,遇阻射孔层无法反应吸水状况定量参数的难题,运用同位素及流量计四参数注水剖面测井资料,总结出了一种注水剖面解释方法,将流量测试进水量校正为同位素解释吸水量,依据同位素测井原理公式,重新计算未测试配注层各层吸水百分比、绝对吸水量和吸水强度,并通过对吐哈油田×区块1口井的解释,验证了该方法的真实、可靠性。

To solve the difficult problem in block perforated layers by radio isotope log calculating quantitative water injection parameter of in separate injection well, proposed is an interpretation method of water injection profile with radioisotope log and four-parameter water injection profile data. Based on radioisotope log principle formula, the tested fluid inflow is revised as water injection volume of radioisotope interpretation. Then, recalculated are water injection percent- age, absolute volume of water injection and water injection intensity of small layers of unknownformation. The method is applied in one well of × block in Tuha oilfield. The interpretation results show that the method is true and reliable.
