人工合成烃类包裹体不仅可以作为分析仪器校正的标样,还可以增进人们对烃类包裹体形成机制和水—岩作用机理的认识。人工合成包裹体的方法主要有三种:人工晶体生长法、焊封石英管法和金刚石压腔法,其中利用愈合人工石英(水晶)单晶裂隙合成流体包裹体技术已成为标准的合成技术。目前人工合成烃类包裹体主要利用晶体生长法合成,包括高温高压利用石英(或方解石)晶体生长愈合裂缝形成流体包裹体和低温下采用过饱和溶液重结晶形成流体包裹体。由于高温高压条件下烃类可能发生裂解,母液保真是成功实现人工合成烃类包裹体的重要前提条件。国外在人工合成烃类包裹体研究方面已经取得了一些重要的认识,但远不及人工合成无机体系流体包裹体研究那样系统和完善。国内关于人工合成烃类包裹体研究尚处于起步阶段,迫切需要开展这方面的研究工作。
Synthetic hydrocarbon inclusions not only serve as a calibration standard for analytical instruments, but also enhance understanding of the formation mechanism of hydrocarbon inclusions and water-rock interaction mechanisms. There are mainly three methods for artificially synthesizing inclusions: artificial crystal growth method, welded quartz tube method and diamond pressure cavity method. The technology of synthetic fluid inclusions using artificial quartz (crystal) single crystal fissures has become the standard synthesis technology. At present, synthetic hydrocarbon inclusions are mainly synthesized by crystal growth method, including high-temperature and high-pressure growth of quartz (or calcite) crystals to form fluid inclusions and the formation of fluid inclusions by supersaturated solution recrystallization at low temperatures. Due to the possible cracking of hydrocarbons under high temperature and high pressure, mother liquor fidelity is an important prerequisite for the successful realization of synthetic hydrocarbon inclusions. Some important understandings have been obtained in the study of synthetic hydrocarbon inclusions abroad, but it is far less systematic and complete than the studies on fluid inclusions in synthetic inorganic systems. Domestic research on synthetic hydrocarbon inclusions is still in its infancy, the urgent need to carry out research in this area.
