摘要:

次生孔隙的发育在一定程度上控制着油气的聚集成藏,并能有效改善火山岩储层的储集性能。依据 大量岩心资料,通过岩石薄片和铸体薄片观察,结合测井资料分析,发现准噶尔盆地滴西地区火山岩次生 孔隙类型多样,主要包括晶内溶孔、基质溶孔、杏仁体溶孔、粒内溶孔、交代蚀变假杏仁体溶孔、构造缝和 溶蚀缝;各种次生孔、缝在演化上存在一定的内在联系,且其形成过程受岩性、构造作用及溶蚀作用的影 响。岩性是次生孔隙发育的物质基础和前提,溶蚀作用和构造破碎是形成次生孔隙的主要作用方式。对次 生孔隙特征和主控因素的研究,有助于开展有效的储层评价和预测。

Abstract:

The development of secondary pores in volcanic reservoir controls the oil and gas accumulation, and has an essential contribution to reservoir. Based on core data, and observation of thin sections and casting slices, combined with the logging data, it was found that different types of secondary pores developed in volcanic reservoir in Dixi area, including phenocryst dissolved pores, matrix dissolved pores, amygdale dissolved pores, intragranular dissolved pores, metasomatic and alterative pseudo-amygdale dissolved pores, structural fractures and dissolved fractures. The secondary pores and fractures have some internal connection in the evolution, and their forming is a complex geological process, principally controlled by lithology, tectonism and dissolution. The lithology is the material basis and prerequisite for the development of secondary pores, dissolution and fracture play a major role in the formation of secondary pores. The study on the characteristics of secondary pores and main controlling factors has a great significance to effective reservoir evaluation and prediction.
