Characteristics and Controlling Factors of Volcanic Reservior in Kelameili Area of Jungger Basin
摘要
Abstract
The volcanic rock reservoir characteristics including lithology, lithofacies, physical properties and pore type of volcanic rocks in Kelameili area of Jungger Basin were analyzed by observing drilled cores, casting sections and thin sections through microscope. The reservoir accumulation types? Physical conditions and main affecting factors were also discussed in this paper. The studies show that the reservoir rocks in the area are intermediate-basic lavas ranging from basalt to andesite and a few rhyolite, pyro-clastics and shallow intrusive rocks such as syenitic porphyry. Moreover, the types of reservoir rocks have a direct effect on the physical properties and reservoir quality. But physical property of volcanic rocks is heterogeneity. The physical properties of volcanic breccia(with 12. 42 % porosity and 0. 796 X 10-3 μm2 permeability) and basalt (with 10. 73 % porosity and 0. 289X10-3μm2 permeability) are better than those of other rocks. The reservoirs are categorized into high porosity-intermediate permeability, high porosity-low permeability, intermediate porosity-low permeability and low porosity-low permeability. They mainly show the trait of low permeability(<l X 10-3 μm2). Their accumulation type was multiplex pore-fracture reservoir, mainly containing tectonic fissure-corrosion fissure-corrosion pore, gas pore-tectonic fissure-corrosion fissure-corrosion pore and intercrystal pore-corrosion pore. The capability of the reservoir is greatly affected by the lithofacies of volcanic rocks, volcanic eruption environment and the later reformation.关键词
