侵入岩脉 meaning in English
intrusive dike
intrusive vein
Examples
- When basement rock rupture pass through the well cross section , the fracture belts can be identified with some evidences , for example , the compensate neutron increasing and the stratum density diminishing synchronization , the dual - laterolog resistance diminishing greatly and the positive difference between the deep laterolog resistance and the shallow laterolog resistance appearing . when the compensate neutron increase , the stratum density diminishing and the dual - laterolog resistance value diminishing slightly , the fracture belts can be confirmed with the intrusive vein at high frequency in well cross section
当有基岩断裂在井削面上通过时，若补偿中子增大与地层密度变小同步发生，双侧向测井电阻率有明显变低并有正差异出现，则可以判别为裂缝发育带；当补偿中子增大，地层密度变小及双侧向幅度变小都不太明显时，则可以利用井剖面中频繁出现的侵入岩脉来确定裂缝发育段。
