新庄油田稠油层测井解释方法研究

Well Logging Interpreting Method of Heavy-oil Layer in Xinzhuang Oilfield

新庄油田是近两年河南油田新增探明石油地质储量的主要探区。针对新庄油田为断块(断鼻)层状边水稠油油藏、含油带窄、含油层段内有多个油水系统且无统一油水边界的地质特点,在研究储层岩性、物性、含油性关系的基础上,依据大量的试油、试采数据,建立了油水层、油干层判别标准,提高了稠油层测井解释精度。

Xinzhuang Oilfield is a key exploration area with newly proved OOIP in Henan Oilfield. In consideration of the geological characteristics of Xinzhuang Oilfield which is a fault block heavy-oil reservoir with layered edge water, narrow oil-bearing zone, many oil-water systems in oil-bearing intervals and without unified oil-water boundary. Standards for judging oil-water layers and oil-dry layers are established according to a great number of formation testing and production testing data based on the correlations of reservoir lithology, its physical property and oil content, by which the precision of heavy oil zone logging is improved.
