Remaining oil distribution controlled by intercalation in reef limestone reservoir;

Study of intercalations in massive Mesozoic reservoir in Wangguantun oilfield;

Reservoir heteroneity of E 2S 6 1 oil bearing formation and the division standard of the uncontinuous intercalations in it were studied based on the geologic data and logging data from 40 wells in Duo Ⅰ member.

The strata,structure and reservoir characteristics of Asmari reservoir were analyzed,especially the fractures and barriers.

By using sedimentary facies markers and related information of cores, well logging, and seism and in combination with regional sedimentary facies modes, the summary indicates that there exists 3 different kinds mudstone barriers in Fault Block Xia 32 of Linnan Oilfield, the connecting modes of sand bodies for barrier control are analyzed.

Study and utilization of interbeds in K_2t_1~2 thick oil layer in Chenbao oilfield;

Analysis of influences of interbed development on effects of water plugging and profile correction;

Influence of the impervious interbeds on the drainage and oil production performance of the thin oil reservoir with bottom water

Study on the distribution of the interlayers in Guantao-6 sand group of No.1 area in the central part of Gudao Oilfield;

Based on microsedimentation,this paper combines with logging interpretation by naked eyes,describes the conglomerate distribution and interlayers,and reestablishes oil reserve model which indicates that Yan107 fault block is a massive ground conglomerate oil reserve,and hence a better oil extraction is achieved by adjusting water flooding.

The interlayer is the main cause to form the heterogeneity of fluid flow in the continental reservoir and is also the major geological factor for controlling complex water-flooded modality of thick layer.
