对低渗天然气层的地层特性进行了描述，提出低渗气层的毛细管压力是地层损害的主要因素，并把它作为平衡压力钻井设计和施工所应考虑的问题，以便在钻井过程中减轻钻井液对低渗气层的损害。
The stratigraphic character of the low permeability gas reservoir is described, and the capillary pressure of the low permeability gas reservoir is the main factor of strata damage. It should be considered as a balanced pressure drilling design and construction in order to reduce drilling during drilling Liquid on the low permeability gas damage.
