用芳香化合物分布判别储层产液性质

Discrimination of reservoir produced fluid property with distribution of aromatic compounds between oil and water zones

储层产液性质判别是录井、测井的基本任务,也是难题之一。特别在涉及到含水油层和含油水层的判别时,更是缺少可靠而有效的方法。利用芳香化合物在油水两相中的分配原理和反相液相色谱对芳香化合物的分离检测技术,测试了67块已知产液性质的储层样品,在此基础上,建立起了两张判别储层产液性质的地球化学图,其对油层、含水油层、含油水层及水层的综合对判率都在83%以上。

Discrimination of reservoir produced fluid property is a basic task and a lso a difficult problem in well logging.There is lack of a reliable a nd effective method especially to di stinguish the reservoir produced fl uid property between water-bearing oil zone and oil-bearing water zone.Base on the partition law of aromatic com pounds between oil and water,and the invers e liquid chromatography,some aroma tic compounds in 67samples with know n reservoir produced fluid property a re analyzed,and two geochemical dis criminating diagrams for reservoir produced fluid property are constructed.The overall correctness is more than 83%with the diagrams for discriminatin g the oil,water-bearing oil,oil-bearin g water and water zones.
