摘要: 近年来准噶尔盆地腹部油气开发的重点和难点是对石炭系火山岩的开发。石西油田54口井石炭系火山岩孔隙性特征与相同埋藏深度的碎屑岩和碳酸盐岩比较,其孔隙度偏高;与较浅火山岩比较,孔隙度也稍偏高。研究表明:石西石炭系深埋藏火山岩储集层高孔隙的发育主要受岩性和成岩后生作用的影响,成岩后生作用是决定性的因素。

Abstract: The emphasis and difficulty is the development of carboniferous igneous rocks oil and gas in the belly of Junggar Basin in recent years. The porosity of fifty-four wells carboniferous igneous rocks in Shixi Oilfiled is being studied. The result has been shown that the higher porosity of conglomerate rocks and carbonate rocks than in similar depth and igneous rocks in shallow depth. The research has indicated that lithology and burial diagenesis determine the development of the porosity of deep-seated igneous rocks in carboniferous in Shixi Oilfield. And burial diagenesis is the key factor.

Key words: Shixi, deep-seated, igneous rocks, high porosity, carboniferous
