摘要
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 characteristics of low permeability gas formation are described in this paper.Drilling in this gas formation, the capillary pressure is the major factor of formation damage, and should be considered in drilling design and operation,so as to decrease the formation damage during drilling.
