西西伯利亚地台文德系科维克琴巨型油气聚集带

A Giant Koveikqin Hydrocarbon Accumulation Belt of Wende System in Siberia Platform

指出了科维克琴油气聚集带的特征，科维克琴凝析气田是该聚集带的一个重要开发对象。描述了油气生成、运移过程、油气聚集带的地质结构、生产层位的地层特征，介绍了勘探成果。研究了有效厚度、地层孔渗特性的变化规律，预测了在油气聚集带范围内的天然气储集层的分布。提出了俄罗斯石油公司在科维克琴油田进行辅助勘探的工作规划，由于完成了这一规划，天然气储量得到了明显的增长，从2003年起科维克琴凝析气田将投入工业性开发。

： The characteristics of Koveikqin hydrocarbon accumulation belt are presented， in which Koveikqin condensate gas field is an important target for development． This paper described in detail the hydrocarbon generation， migration process and geological structures of the accumulation belt， stratigraphic features of pay zones and exploratory results， and made an analysis of changes of net pay thickness， porosity and permeability， and a prediction of gas reservoir distribution within the belt． In addition， a work planning for assisted exploration in Koveikqin field provided by the PetroRussia Company was proposed． Since then， its gas reserves have gone up obviously． It is scheduled that Koveikqin condensate gas field will be brought into commercial production．
