deviating hole meaning in English
偏斜孔
斜钻孔
Examples
- In drilling high angle deviated holes , friction is the main factor affecting the effective wob
在大斜度定向井钻井过程中，摩擦阻力是影响有效钻压的主要因素。 - With the development of worldwide petroleum industry , deviated holes , branch holes and horizontal wells are used to exploit oil reservoir which is smaller , thinner and worse . logging while drilling ( lwd ) is used to evaluate and geosteering drill in this kind of reservoir because of its characters
随着世界石油工业的不断发展，大斜度井、分支井和水平井等钻井技术越来越多地被用来开发规模更小、油层更薄、物性更差、非均质性强的油藏。 - Parameters can be interpreted through the method used in straight wells . after logging curves in horizontal wells are revised to true vertical depth , oil - bearing formation is evaluated through the comparison of wells combined with geological information . logging while drilling have great difference with ordinary cable logging especially in deviated holes and horizontal wells . comparison of cable logging and lwd carried out in different time indicates characters of mud invasion
实际解释lwd资料时首先需对随钻测井资料进行预处理和标准化，然后从随钻测井、录井资料中提取与岩性密切相关的参数，建立测井相-岩相统计模式，并采用灰色关联识别方法实时判别地层岩性；采用直井的参数解释方法进行随钻地层参数解释；将水平井的随钻测井曲线从实际井深校正到垂直井深上，通过随钻测井资料与邻井测井资料的对比解释，并结合地质、录井资料进行随钻地层含油气性评价。
