ժҪ�� For the purpose of reservoir characterization of oilfields discovered in Albertine Graben,it is neces-sary to study the regional stratigraphy and sedimentary characteristics.The Semliki outcrops display a complete stratigraphy of Miocene,and the sediments are likely to provide valuable analogues for the reservoirs at Alber-tine Graben oilfields.The outcrops were observed and described in detail,mainly including lithology,colour,thickness,grain size and sedimentary structure.The sedimentology,depositional environment,climate,reser-voir geometries and dimensions were analyzed.The Miocene stratigraphic section of Semliki basin was finally es-tablished,with lithology,sedimentary structure,sedimentary cycle,interpretation and climate information on it.It provides an analogy for the reservoir characterization,especially provides a basis for appropriate prediction of reservoir geometries in the field.

Abstract: For the purpose of reservoir characterization of oilfields discovered in Albertine Graben,it is neces-sary to study the regional stratigraphy and sedimentary characteristics.The Semliki outcrops display a complete stratigraphy of Miocene,and the sediments are likely to provide valuable analogues for the reservoirs at Alber-tine Graben oilfields.The outcrops were observed and described in detail,mainly including lithology,colour,thickness,grain size and sedimentary structure.The sedimentology,depositional environment,climate,reser-voir geometries and dimensions were analyzed.The Miocene stratigraphic section of Semliki basin was finally es-tablished,with lithology,sedimentary structure,sedimentary cycle,interpretation and climate information on it.It provides an analogy for the reservoir characterization,especially provides a basis for appropriate prediction of reservoir geometries in the field.
