The Research and Application of Multiple Collaborative Anti-Sloughing Drilling Fluid

Abstract:

In order to solve the downhole complex issues such as lost circulation, sticking and well collapse during drilling due to the development of coal-bed and coal seam, thick carbonaceous shale, formation is not homogeneous, the inclination is large, well-developed cracks and other reasons, which constraint exploration and development of oilfield in Huoyanshan tectonic belt region. According to the well instability mechanism of this block and the principle of "Materialized blocking, inhibiting surface hydration, effective stress support" multiple collaborative anti-sloughing drilling fluid, we developed a set of new drilling fluid systems suitable for the Huoyanshan tectonic plate through laboratory experiments. Field test application results show that the new drilling fluid system has a strong capability of salt resistance, anti-calcium and anti-poor soil, has excellent ability of anti-collapse, and has better temperature resistance and crack sealing ability. The new drilling fluid meets the needs of drilling under complicated geological conditions completely.
