【 摘 要 】

The western ring belt of Mahu depression is located in the Mahu well area of the western slope of the central depression of Junggar basin. According to the actual drilling data, The reservoir pressure in this well area changes greatly and is affected by fracture, lithology and seismic data quality, It is difficult to accurately predict the pressure before 3d drilling, and the mechanical drilling speed and single drill footage are very low. To this end, the 9-1/2"SF56VH3 and 6-1/2" SF54VH3 PDC bit was developed in Mahu well area, and the downhole condition of the bit was simulated by finite element software. The results show that: In the application of 60 Wells, the average mechanical drilling speed of the whole well is 7.24m/h. Special Ma6229 well three - open average speed up to 10.72 m/h, which fills the gap of Xinjiang in the field of personalized design of PDC bit. Meet the needs of Mahu oilfield.
