大牛地气田无土相钻井液流变模式优选

Rheological Model Optimization of Non-solid Phase Drilling Fluid in Daniudi Gas Field

摘要:

大牛地气田无土相钻井液实例计算表明，赫巴模式的相关系数最大，残差平方和最小，其次是卡森模式、幂律模式，最差的是宾汉模式，建议优先选用赫巴模式。

Abstract:

It was showed by the example calculation of non-soil phase drilling fluid in Daniudi gas field that the correlation coefficient of Herschel-Bulkley model was the largest with the smallest residual sum of squares; than was the Casson and power-law model; Bingham model was the worst. Herschel-Bulkley model was suggested.
