| 摘 要： | 油气藏油水界面的变迁记录了油气藏形成以后调整、改造甚至破坏的历史.恢复各地质时期的古油气水界面的位置, 可以帮助我们确定地下烃类流体运聚成藏的时间, 恢复流体成藏后的变迁、调整过程, 认识油气藏形成、分布的规律, 对研究区作出较为准确的资源评价.应用含油包裹体颗粒指数(GOI) 方法和定量颗粒荧光(QGF) 技术对塔北地区典型油气藏的古油水界面进行了恢复, 结果表明, 塔北地区志留系古油藏古油水界面的位置低于现今沥青砂岩段底界的位置, 沥青砂岩段底界并不是古油层的底界, 在沥青砂岩段之下还有一段古油柱, 在油藏破坏过程中, 这部分原油运移到构造的高部位了, 没有在原地留下沥青; 沥青砂的厚度小于古油柱的厚度, 这意味着古油藏的规模要大于现今油藏规模.

| Abstract: | Changes in hydrocarbon-water contact record the history of the adjustment, reconstruction and even destruction of reservoirs. Restoring the positions of paleohydrocarbon-water contact of reservoirs in different periods of geological history can determine the timing of migration, accumulation of hydrocarbon and reservoir adjustment. This can aid in understanding the laws governing the formation and distribution of reservoirs and assist in the evaluation of petroleum resources. The paleohydrocarbon-water contact of the typical reservoirs in northern Tarim was restored using the methods of GOI and QGF. The results show that the paleohydrocarbon-water contact of Silurian reservoirs in the northern Tarim is lower than the bottom of the current asphalt sandstone. That is, there is a paleo-oil column below the current asphalt sandstone and the oil in it has migrated into the structural high and has not left the asphalt during the period of the reservoir's destruction. So, the thickness of asphalt sandstone is less than the height of the paleo-oil column, which means the szle of paloreserviores is bigger than that of current reserviors. |
