西伯利亚地台腹部文德系及下寒武统含油气性预测(俄文)

A Prediction Method of the Petroliferous Property in Lower Cambrian and Vende System in Hin terland of West Siberian Platform.

经过改进的含油气性预测方法,适用于结构复杂和油气藏形成期长的古老地层。这种含油气性预测方法是建立在综合地层、构造、岩性-岩相、地球化学和本文地质指标和对每种指标进行评价的基础上的。介绍了盐下陆源层和碳酸盐岩层(维柳依、下涅普斯克、上涅普斯克齐尔、下达尼洛夫、上达尼洛夫和乌索尔等储集层)的含油气性的详细预测结果。在它们的分布地区划分了不同含油气性的详细预测结果。在它们的分布地区划分了不同含油气远景区,油气聚集带和首批应进行石油普查的目标,预测了这些地区的主要圈闭类型、油藏数量和烃类组分。这些研究成果将能极大地提高石油普查的效果。

This important method for prediction of petroliferous property is suitable to predicting the ancient for-mation with complicated textures and petroleum reservoirs that shaped for a long period.This method is based on the comprehensive indexes,such as strata,structure,lithology-lithofacies,geochemistry and hydrogeology,and evaluations of these indexes.This paper presents petroliferous properties of subsalt terrestrial beds and carbonate rocks along with detailed prediction results.They are Welue,Lower Niepsk,Upper Niepskqir,Lower Danilov,Upper Danilov and Wusol reservoir.For these distributed areas,various petroliferous potential domains,petroleum accumulation zones and the first batch of targets to be going to perform petroleum reconnaissance survey are classified and proposed.And predic-tions of their main trap types,reservoir quantities and hydrocarbon composition.These achievements will greatly im-prove the effectiveness in petroleum reconnaissance.
