Abstract:

Current borehole evaluation methods such as mud shale specific area measuring method, mud shale hydration swelling measuring method, drilling fluid cake compressibility evaluation method and so on are suitable for shale formation collapse. Whereas there is no a feasible evaluation method on how to stabilize fracture formation and crack strata .Plugging effects of drilling fluid and completion fluid on fractured formation have been evaluated by mud filter press 387-42 and results have show that it is a effective method for evaluating drilling fluid and completion fluid in the oilfield.

Key words: hole sloughing prevention, filter press, plugging, fractured formation, evaluation
