试油层产液性质的多参数综合判别方法研究

Research of the Comprehensive Discrimination Method by Multi-Parameters on Producing Fluid Property of the Well Testing Formation

通过对塔里木油田碎屑岩地层反映产液性的录井、测井资料和试油成果资料综合分析对比,提出了预测储层产液性质的新方法——综合权值法。该方法通过一定的规则给电测解释结论、岩芯含水迹象、滴水试验、含油饱和度、孔隙度、原油粘度等与产液性相关的因素赋以权值,求得综合权值,对储层产液性质进行综合判别。利用该方法判断储层产液性质具有操作简单、判别率高等优点,对于更合理地优选试油层位和优化试油方案具有重要的实际应用价值。

By comprehensive analysis and comparison of the data related to the liquidity of clastic formations in Tarim oilfield reflect, including well logging and logging as well as well testing results, a new comprehensive discrimination method, called comprehensive weighted value method, is suggested. This method chooses several important correlation factors such as conclusion of electric log interpretation, water holding indication of drilling core, test of dripping water, oil saturation, porosity and viscosity of crude oil and are attributed respectively weighted values according to certain rule which is used to discriminate the liquidity of the formation. This method has advantages of simple operation and accurate discriminating result which has an important actual value for reasonably choosing the formations to be tested and optimizing well testing scheme.
