It’s very easy to damage reservoirs in the process of drilling and exploring, and the damage will directly affect the output of gas field. In order to reduce this damage, it is necessary to analyze the factors of reservoir damage. Taking the lowpermeability sandstone reservoirs of the first, second and third members of Lower Permian Shihezi Formation as examples, based on the test analysis, it is believed that reservoir damage mainly caused by alkali sensitivity and water lock, and there exists solid intrusion and weak salt sensitivity, water sensitivity. Correspond countermeasure is proposed so as to provide basis for field production and ensure high and stable gas field production.
