Abstract

The previous drilling practice showed that there were many drilling difficulties in igneous rock, such as less footage of one bit, lower roundtrip ROP, more tripping times, etc., which severely influenced the exploration and development process of carboniferous formation. After analysis, the reasons are mainly as follows: (1) Igneous rock has high hardness and poor drillability, which generally led to the few footage for tricone bits. (2) Igneous rock has complex lithological characters and poor homogeneity, which resulted in the limited use of PDC bits. (3) The formation dip angle of piedmont tectonic belt in BH block is big, which made well deviation grow fast.
