摘要

Deep and ultra-deep drilling technologies have been developed since the late 1930s, and got great achievements especially in the last two decades. The depth of well completion has even reached to 12 kilometers. Several countries, such as US and some European countries, are leading in the advanced deep and ultra-deep drilling technologies in the world. In recent years, nevertheless, PetroChina has also made big progress in mechanical penetration rate (ROP), drilling period, amount of drilling bit used in a single well of deep drilling as well as in deep drilling equipments. Compared with the high-level technologies of complicated deep drilling in the world, PetroChina still has a long way to go.
