When the gas saturation in formation is high, the characters of low neutron, low density, high interval transit time and high resistance are obvious;
当地层含气饱和度较高时，有低中子、低密度、高时差及高电阻率特征明显；
It is theoretically considered that reservoir gas-bearing makes interval transit time porosity and density porosity increase and neutron porosity decrease.
理论上认为，储层含气使声波时差孔隙度和密度孔隙度增大，使中子孔隙度减少。
It shows that density has a better linear relation with different reservoir parameters, but the relation of sonic interval transit time or velocity with reservoir parameters is very complicated.
这说明密度与各储层参数之间具有较好的线性关系，而声波时差或速度与储层参数之间的相互关系要复杂得多。
