deviated drilling 中文意思是什麼
deviated drilling
解釋
偏斜鉆井-
In drilling high angle deviated holes, friction is the main factor affecting the effective wob
在大斜度定向井鉆井過程中，摩擦阻力是影響有效鉆壓的主要因素。 -
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
隨著世界石油工業的不斷發展，大斜度井、分支井和水平井等鉆井技術越來越多地被用來開發規模更小、油層更薄、物性更差、非均質性強的油藏。 -
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
實際解釋lwd資料時首先需對隨鉆測井資料進行預處理和標準化，然後從隨鉆測井、錄井資料中提取與巖性密切相關的參數，建立測井相-巖相統計模式，並採用灰色關聯識別方法實時判別地層巖性；採用直井的參數解釋方法進行隨鉆地層參數解釋；將水平井的隨鉆測井曲線從實際井深校正到垂直井深上，通過隨鉆測井資料與鄰井測井資料的對比解釋，並結合地質、錄井資料進行隨鉆地層含油氣性評價。 -
