Field Research and Application of Tracking Adjustment Technology While Drilling for a Horizontal Well in Block A

A reservoir in Block of an oil field is a new layer series the area, and horizontal well has been deployed for first time around development target third section reservoir. Compared with layers old structure more complex, changes rapidly, prediction sand-laden mud difficult, tracking adjustment wells while drilling difficult. In view above problems, order to ensure effect, we have carried out basic geological research combination earthquake, study correlation between rock electricity multi-technology combination, innovatively formed supporting technical methods fine fault, micro-amplitude identification prediction, established three-dimensional model, optimized location trajectory optimization design favorable blocks, According process “making plans before drilling, timely during re-recognition after drilling”, 7 tracked adjusted average rate 85.3%, which achieved good results increased reserves productivity.
