the quality of upper Paleozoic reservoir is decided by the deposition and diagenesis jointly.

Burial diagenesis causes a progressive transformation of smectites, the end-products being dependent on PH and pore water chemistry.

The non homogeneity of diagenesis and tectogenesis make the characteristic of physical property different obviously.

sand body thickness, rock facies and diagenesis control the properties of reservoir commonly.

There also developed many types of diagenesis, and the destructive diagenesis is dominated one.

The relationship between tight sand reservoirs and sedimentation and diagenesis is also discussed.

The main factors controlling the reservoir quality are diagenesis and depositional facies.

However, the different types of rock's diagenesis influence porosity greatly.

Diagenesis control the porosity evolution, with symbolic meaning, it is very important for the exploration of the oil and gas.

The Mesozoic clastic reservoirs in Zhuanghai area are chiefly affected by sedimentation, diagenesis and tectonism.

Diagenesis and pore evolution have exerted great effects on the properties of reservoir rocks.

Comprehensive analysis is made on all patterns of carbonate diagenesis and the vertical distribution features of diagenetic environments.

The porosity evolution of reservoir is closely related with the diagenesis types.

The main diagenesis of SQ8 are pressure solution, kaolinite corrosion and quartz overgrowth, el al.

At the edge zone of platform and deep sea basin, there are reef flat reservoir and various diagenesis, it's good for reservoir develop.

138 experienced two stages of sedimentation-diagenesis and reworking-regeneration.

These include quartz, chlorite and other pore-filling minerals or cements that grow during diagenesis.

According to the influence on petrophysical property, reservoir diagenesis is classified as destructive and constructive type.

Conclusion The sandstone pore structure and diagenesis are main factors influencing Chang 3 reservoirs microanisotropy.

Diagenesis study shows that mixing-water dolomitization and associated erosion were of great importance to the development of reservoir.

Zedites could be generated throughout the process of diagenesis .

those caused by high bound water saturation are controlled by deposition and diagenesis.

Sandstone has entered the late diagenesis Asubage period.

The diagenesis of Member He2 and Member He3 in Daniudi gas filed includes compaction, cementation, dissolution and denudation.

These diagenesis caused the the primary porosity be exhaust of da'anzai carbonate rocks, and make the reservoir to go bad.

The mechanism of decreasing reservoir penetrability which was caused by the clay action, the sedimentation and the diagenesis were analyzed.

The formation of sandstone-type uranium deposits is not only related to sedimentary environment, but also related to diagenesis environment.

They can study not only reservoir diagenesis , but also analyze flowed fluid history, components and nature.
