煤田造浆地层泥浆应对措施

Countermeasures of Slurry in Coal Slurry Formation

煤田钻探孔常遇不稳定地层,基于其孔壁不稳定、钻孔漏失等因素导致钻孔坍塌,根据煤田地质特征,选用合理的泥浆,解决煤田造浆地层的复杂问题,实现稳定快速穿过。

Coalfield drilling always with soft ground, based on its unstable drilling, drilling hole leakage that led to borehole collapse, based on geological factors, reasonable slurry was chosen to solve coalfield slurry stratum problem and realize rapid and stable crossing.
