Based on field geology investigation and laboratory research, the distribution, petrologic characteristics and oil reservioring characteristics of the reservoir in the area are studied for the first time.
On the basis of the delta depositional systems, petrographic characteristics, geochemical characteristics of the rare earth and trace elements of different delta depositional systems, and the evolution process of the delta depositional systems of the Member 6-2 in the Yanchang Formation are elaborated in detail.
In order to solve this problem, the author have studied the Lithological characteristics, forming environment,volcanic facies and reservoir quality of volcanic rocks in Xujiaweizi region, and try to supply essential basic theory sustain for prospection and exploitation of volcanic reservoirs in this region.
Based on a great deal of analytical data of rock and mineral, discussed. the controlling factors on clastic rock reservoir property in the southwest area of the Qaidam basin are the sedimentary environment, lithological characteristics, buried history, unusual high fluid pressure, salt lake environment were main factors deciding reservoir diagenetic evolution and reservoir property.
Influence of petrographic characteristics of coal on its methane sorption
Stratigraphic and petrographic characteristics of the Creta copper shale deposit in the Flowerpot Shale of southwestern Oklahoma are compared with the betterknown Rudna deposit in the Kupferschiefer of south-western Poland.
It is here argued that the geochemical and petrographic characteristics of the massif are compatible with its formation at the axis of a slow spreading ridge within a small, marginal ocean basin.
The petrographic characteristics of the CA nodules show that they were formed as crystal fractionates from a basaltic melt.
Fiamme from the tuff cluster in chemical compositions and petrographic characteristics, indicating the magma chamber was not continuously zoned but consisted of at least seven compositional layers.
Lithological characteristics, physical properties, grain size composition, and chemical composition (based on the neutron activation analysis) of clay minerals are studied.
Lithological characteristics and geochemical data suggest that elevated levels of As are found in organic-matter-rich clay and silty sand rather than sand samples, with occasionally enriched As content in iron-oxyhydroxide-coated sand grains.
Core samples collected from the shelf off north Kerala (SW coast of India) were studied for faunal assemblages (pteropods and foraminifers), calcium carbonate contents and lithological characteristics.
Both the over-accretion (i.e., Moho penetration) and the under-accretion (i.e., Moho underplating) of magmas can readily explain complexities in the lithological characteristics of the continental Moho and lower crust.
Horizontal differentiation of the lithology of mud deposits is mainly influenced by two factors: the geological-lithological characteristics of the source areas for every reach of a river valley and the river channel pattern.
