摘要

摘要: 应用地震和测井、岩心描述、地质录井、岩心与岩屑微观测试分析等信息,研究了塔里木盆地塔中地区早二叠世岩浆岩岩石类型、单井相分析、产状、期次、发育与分布等特征和规律;论述了本期岩浆活动对烃源岩、油气储集层、油气运移、圈闭和成藏等的影响,认为早二叠世岩浆活动有利于增加和改善油气运移的通道,能使相邻烃源岩在短期内经历异常高温和催化改造而成熟并增加生烃量,改善油气储层质量和形成岩浆岩遮挡的半背斜圈闭与油气藏等。

Abstract: Characteristics, distribution patterns and hydrocarbon accumulation relations of the Early Permian magmatic rocks in the Central Tarim have been studied with well geological data and core and rock testing and analysis information. Types, lithofacies, occurrences, development and distribution of the Early Permian magmatic rocks in the studied area are discussed in this paper. Relations between the hydrocarbon generation and accumulation and the Early Permian magmatic activity in the area are shown. The activity does not destroy oil and gas formation and accumulation, but is favorable for a large quantity of hydrocarbon to generate from source rocks, as the high thermal fluid brought by magma activity could increase ancient geothermal gradient, and accelerate the evolution history of source rocks. Also, magmatic activity could result in the formation of more channels for oil and gas migration and accumulation, and form many secondary pores and fissures. In addition, magmatic rocks could seal hydrocarbons in traps and pools.
