Stress sensitivity evaluation test and protective technique research on low-permeability fractured carbonate reservoir: a case of Ordovician buried hill hydrocarbon reservoir in Tarim basin

A series of simulated fractured core samples made of stainless steel with a given width of fracture were used to evaluate the damage of drilling fluid to fractured carbonate reservoirs in laboratory.

The paper reviews advances in protection technology of fractured carbonate reservoir in recent years and chiefly introduces the present situation of damage evaluation,damage mechanism and protection technology about fractured carbonate reservoir.
