Alluvial fan and oil-water distribution characteristics of Xiawuerhe Formation in Well 530 field of Karamay Oil Field, Xinjiang, China;

In face of the complicated oil-water distribution in the thick sandbody and the identification difficulty of the type of the reservoir traps in this area,the distribution character of main interlayer was described, and the replacement pressure of interlayer was calculated beginning with the study of heterogeneity.

compute technique, sandstone distribution, reservoir characteristics, distribution of flow unit, reservoir characteristics and oil-water distribution of Chang 2_1~1 oil segment were reseached deeply and comprehensively.

Geological characteristics and distribution of oil and water in Silurian buried hill reservoir in Yaerxia oilfield, Jiuxi basin;

Fluvial facies reservoir architecture and its control over the distribution of oil and water;

Aimed at the complicated distribution of oil and water in the thick sandbody and the difficulty of identifying the trap type in Moxizhuang,Junggar Basin,the heterogeneity of the reservoir was studied and the origins of interlayer and permeability barrier and their function on the oil and gas distribution were discovered.

Complexand levityof geological conditions for forming oil reservoirs result inthe complexand levityof oil/water distribution,especially,in low permeability reservoirs.

The relationship between reservoir heterogeneity and oil/water distribution has been analyzed.

By using advanced water injection technique,low pressure and low permeability reservoir in Niujuanhu block of Santanghu Basin was effectively exploited,whereas the oil production fell and water content increased rapidly,the study was aimed at characterizing oil and water distribution during advanced water injection process.
