  • Drilling, logging and core sample data showed that about 25.1% of wells in district no.12 in the Tahe Oil Field were filled, resulting in low production efficiency. The correspondence between logging data and different filling materials was discussed. The production of filling caves with different filling materials was studied in view of well yielding. Based on the ideal cave sequence proposing by Loucks, acid fracture avoiding filling caves was practiced in the upper broken area or the lower collapsed area to improve oil production.
