The major controlling factors of the reservoir are that the sedimentary microfacies control the scale and scope for aggregating of oil and gas,and the diagenetic facies restrict the rule of oil and water distribution rule,and the physical property heterogeneity determine for heterogeneous distribution of oil and water.

Study on reservoir heterogeneity of clastic rock of Shahejie formation in Dongying sag;

Relation between infilling patterns of short-term base-level cycle and macroscopic reservoir heterogeneity-taking Chang6 to Chang7 turbidite fan of Yanchang Formation in Longdong area as an example;

Reservoir sedimentary characteristics and heterogeneity of block Cao 4,member 4 of Shahejie formation in Lean Oilfield;

The sedimentary environment of lower Karamay formation is alluvial fan,and reservoir heterogeneity is very strong in the central part of No 6 block of Baijiantan oilfield.

The reservoir heterogeneity of Liuhua 11?1 Oilfield was quantitatively characterized.

Sedimentary microfacies and reservoir heterogeneity of the turbidite sand bodies in the middle 3rd Member of the Shahejie Formation in the T74 district of Shengtuo oilfield were studied systematically based on the core observation, electrofacies analysis, well log interpretation and image analysis.

Influence of rock inhomogeneity on strength-size effect of rock materials;

Influence of rock inhomogeneity on softening process after stress of peak value;

Good connectivity and physical property and poor inhomogeneity are identified along the parallel direction of sediment supply,and vice versa along the vertical direction of sediment(supply).

The pore distribution and physical properties of the clastic reservoir rock in Shahai Formation very distinctly,microscopic anisotropy is high.

It also studies the anisotropy of the reservoirs in line with the permeability.
