水力压裂缝高度的偶极横波判断方法

A method of water power pressure altitude judgment by dipole shear wave logging

水力压裂高度的评价一直是评价储层酸化压裂效果的关键,传统的方法根据井温测井、放射性示踪剂测井来判断水力压裂高度,但这些方法均存在施工时间受限的缺点,并且放射性示踪剂测井还对地层有一定的污染。经过研究和应用,得出交叉偶极横波资料也可以很好地评价裂缝的压裂高度,并且该方法具有施工风险小、无污染、快速准确的特点,且测井时间不受限制,是一种值得推广的测井技术。

The approval of hydraulic fracturing altitude has always been the key to the reservoir acidification compression fracture effect.The traditional methods are based on the temperature log,and rely on the radioactive tracer log to judge the hydraulic fracturing altitude.But these methods are limited in construction time,and the radioactive tracer log also causes certain pollution to the stratum.After research and application,we know that overlapping dipole shear wave log can be applied to appraise crack compression fracture altitude.This method has the construction risk not pollution,the fast accuracy characteristics of besides the oil well logging time is not limited,so this technology is worth promoting.
