The result shows that the main reasons are high bottomholetemperature, corrosion of drilling tool during storage and drilling process, high value of formation drillability, and multi-fault.
The results show that the test error of sample A with large angle coefficient of holebottom is under 5%, and will become smaller with the increase of furnace temperature;
