中文摘要：
储层矿物润湿性制约了流体的微观流动特性,从而影响流体在储层的微观分布特征。油和水在矿物表面的润湿性差异导致油气充注过程中形成不同特征的流体包裹体类型。矿物表面实验分析表明,对于水和原油而言,石英具有较明显的亲水性,而方解石的亲水性和亲油性差别不大。轻质油（汽油）在矿物表面完全铺展,储层矿物具有明显的亲油性。通过在不同油气条件下的人工合成包裹体实验模拟和天然储层中的流体包裹体观察分析,讨论了矿物润湿性对储层流体包裹体形成制约作用及其对成岩作用的影响。实验结果证实,由于轻质油的润湿性很强,在充注过程中容易发生侵位驱排水,明显影响矿物晶体生长,成岩作用受到抑制,流体包裹体难以形成,包裹体数量显著减少;而重油充注过程的影响不是特别明显。总的来看,石英比方解石更具有亲水性,在同样条件下,油气在充注过程中相对难以进入石英颗粒的微裂隙中,而容易进入方解石微裂隙,因此在方解石中更容易形成烃类包裹体。
英文摘要：
The wettability of minerals constrains the characteristics of micro-flow and distribution of fluids in reservoirs.The difference of wettability between oil and water lead to different types fluid inclusions formed in reservoirs.Experimental analysis of mineral surfaces show that quartz is distinct hydrophilic,but the wettability of calcite is no obvious difference between water and crude oil.Gasoline extend completely on quartz and calcite,it means that all minerals are oleophilic for light oil.Experiments of synthetic hydrocarbon-bearing inclusions and analysis of fluid inclusions from natural reservoir indicate that wettability have great effect on forming of fluid inclusions and diagensis in reservoir.Results of experiments proved that it have significantly effect on mineral crystal growth,diagenesis be suppressed,and the number of hydrocarbon-bearing inclusions decrease during accumulation of light oil.However,it does not remarkable effect on diagensis and forming of inclusions during emplacing of heavy oil.Overall,it is more difficult for oils to inter cracks of quartz than calcite during accumulation of oil and gas because quartz is more hydrophilic than calcite.So,it is always more hydrocarbon-bearing inclusions in calcite than quartz in same reservoir.
