Study on Optimal Drilling Bits in North of Erdos

Abstract:

To meet the need of exploration in Tabamiao Area of Erdos , the bit type was selected by making use of the data from well observation and optimizing bit type and drilling parameters by site practice. In the application of new type of PDC bits, the number of bits used for a single well was reduced 3~4, well-completing period was shortened 3~5 days.
