摘要
设计不同温度、油水比及不同油品的人工合成方解石烃类包裹体试验,对合成烃类包裹体的岩相学特征、均一温度、荧光测试结果进行分析,讨论油水比、温度及油品性质等因素对方解石成岩作用的影响。试验表明:油气条件下方解石晶体能够继续生长捕获烃类包裹体,但受到了一定抑制,抑制作用随着含油饱和度增高而增强;油气可能会完全终止矿物的生长,但边界条件还有待于进一步确定;温度可能会引起储层成岩环境酸碱度的变化,对方解石生长产生不同影响;轻质油对方解石晶体生长的抑制作用要相对大于重质油的。
Experiments in different temperature, oiL/water ratios and oils were carried out to synthesize hydrocarbon inclusions in calcite. Through analyses of petrographical character, homogenization temperature, and microfluorometric results of synthetic hydrocarbon inclusions, the effects of oil/water ratios, temperature and oil property on diagenesis of calcite were researched. The results from the experiments show that calcite could continue growing and trapping hydrocarbon inclusions under hydrocarbon emplacement, but the growth was restrained by hydrocarbon. The retarding effect became more intense along with oil saturation increasing. Oil and gas might terminate the growth of mineral but the boundary condition needs further confirmation. The PH value in reservoir might change because of temperature change and it brings different impacts on growth of calcite. The inhibitory effect of light oil on the growth of calcite was relatively more intense than that of heavy oil.
