石炭系火山岩岩性测井识别——准噶尔盆地西北缘红车断裂带

VOLCANIC LITHOLOGY IDENTIFICATION OF CARBONIFEROUS SYSTEM--HONGCHE FAULT ZONE OF NORTHWEST MARGINE IN JUNGGAR BASIN

在石油天然气勘探开发过程中，勘探开发的目标一直是沉积岩储层。近年来，国内外相继发现火山岩油气藏，火山岩油气藏成为勘探目标之一。但火山岩具有岩石类型多、岩性较为复杂的特点。火山岩岩性识别是岩相划分、储层综合评价、井网部署、开发方案编制的基础。本文介绍了火山岩储层及岩相特征、火山岩的测井响应特征，简单阐述了火山岩岩性识别的方法。随着测井技术的发展，新的火山岩岩性识别方法将不断提出。

Sedimentary rock reservoirs have been always the target in oil and gas exploration and development.In recent years,volcanic hydrocarbon reservoirs have been found one after another at home and abroad.They become one of the exploration targets.However,volcanic rocks have characteristics of various type and complex lithology.Volcanic lithologic identification is the foundation of lithofacies division,reservoir comprehensive evaluation,well network deployment and development plan establishment.The paper introduces volcanic reservoirs,lithofacies characteristics and logging response characteristics.It also formulates the method to identify volcanic lithology.More and more lithologic identification methods will be proposed with the development of logging technology.
