Characteristics and Quantitative Distribution of Zeolite in Glutenite Reservoirs

The Lower Wuerhe Formation in Mahu 1 well area of Junggar Basin is rich in oil and gas resources, which are rich in zeolite cements. In this paper, based on core observation and scanning electron microscope data, we clarified that there are four types of zeolite minerals, mainly turbidite, followed by zeolite, and occasionally zeolite and clinoptilolite. Based on the data of X-ray diffraction, physical properties and thin sections, there are two genetic modes of zeolite minerals in this area: cementation and volcanic erosion. For the first time, the prediction model of zeolite content was established by the method of multiple regression, and the plane distribution map of the content of turbidized zeolite in the target strata in the study area was established. The study found that zeolite mainly distributed in the conglomerate size in fine conglomerate and small conglomerate, and the microfacies mainly distributed in the front zone of fan delta.
