摘要
包裹体技术在我国被广泛用于确定油气的成藏期。在应用过程中 ,假设条件和涉及到的不确定因素 (矿物的结晶温度、地表温度、埋藏史和热演化史 )较多。由于涉及到的任何一个因素有误都可能导致不正确的结果 ,因而将该技术与确定油气成藏期的其他技术结合起来进行综合研究 ,才能更准确地确定出油气的成藏期。包裹体技术具有三大发展趋势 :①与其他技术一同使用 ,从而更好地解决相关的地质问题 ;②强化对有机包裹体的研究 ,定量研究石油包裹体丰度可以更好地确定古油水界面 ;③对有机包裹体成分的研究从定性到定量 ,定量的分析结果可以用于推测油气的充注史和确定砂岩储层的分割化。
The fluid inclusion techniques are widely used in China to determine the time of oil-gas charging in sedimentary basins. Many assumptions and the uncertain factors such as precipitation temperature of hosting authigenic mineral, surface temperature, burial history and thermal history are often involved in the determination of oil and gas entrapment time in the application of the techniques, which easy results in errors, even if only one of the factors was not correctly assumed or known. Thus the fluid inclusion techniques should be integrated with other dating techniques (methods) to derive a more accurate period of oil-gas entrapment. Additionally, the development trends of fluid inclusion techniques are as follows: ① The fluid inclusion techniques have been integrated with other techniques to solve the complex problems encountered in oil-gas exploration. ② Studies of organic inclusions have advanced to a new stage. The fluid inclusion data of grains with oil inclusions have been successfully applied to determine contacts of ancient-water and oil. ③ Analyses on petroleum fluid inclusions tend to be conducted within a quantitative framework. The quantitative compositional data have been used to deduce the filling history of oil-gas traps and determine compartmentalization of sandstone reservoirs.
