洛带气田蓬莱镇组浅层气藏的储层孔隙度、渗透率及压缩规律的实验研究表明，随着围限压力增加，孔隙度及渗透率相应降低，当围限压力增加到１０ＭＰａ时，测得的孔隙度、渗透率与常温、常压下测定的孔隙度、渗透率相比最大可分别下降７３９和８０。储层孔隙度的变化与钙质、硬石膏的含量有密切关系。据岩芯薄片资料建立了相应的数学关系式。结构参数描述说明，该气藏的ⅠⅢ类储层喉道半径主峰分布在０４～４０μｍ喉道半径之间，而９０以上的累积渗透率贡献则分布在喉道半径为１０μｍ以上，说明大喉道对气体的运移起主要的控制作用
The experimental study on the reservoir porosity, permeability and compressibility of shallow gas reservoirs in the Penglaizhen Formation in Luodai Gas Field shows that the porosity and permeability decrease correspondingly with the increase of the confining pressure, and when the confining pressure increases to 10 MPa, The measured porosity and permeability can be reduced by a maximum of 739 and 80% respectively compared with the measured porosity and permeability at normal temperature and pressure. The change of reservoir porosity is closely related to the content of calcareous and anhydrite. According to the core sheet information to establish the corresponding mathematical relationship. The description of structural parameters shows that the main peak of the throat radius of type ¢ ó reservoir is distributed between the throat radius of 04 ~ 40 μm, while the cumulative permeability of above 90 lies in the throat radius of 10 μm The above shows that the major throat of the gas migration plays a major role in the control
