lwd 中文意思是什麼

lwd 解釋
隨鉆測井
  1. 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。
  2. 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。
  3. Geosteering drilling in horizontal well by logging is an important application of lwd

    水平井鉆井的地質導向是隨鉆測井的重要工程應用。
  4. This study made a conclusion ? amely in order to realize following the geological target while drilling, on the basis of making a better geological and drilling design for horizontal well, we must make full use of mwd, lwd and integrate logging to carry out lithfacy identifying in real time, the lwd interpretation and formation evaluation, to set up geological model of target formation, to select geosteering marked formation and compare simulative curves with lwd curves f to fix on the drilling direction of bit upper and declination, the position in target oil - gas layer, to revise borehole track in real time, to make it extend in reservoir better interval as possible

    研究認為，在做好水平井地質設計和鉆井設計的基礎上，要實現隨鉆跟蹤地質目標鉆井，必須充分利用隨鉆測量、隨鉆測井和錄井等資料，從實時巖性識別、隨鉆測井解釋和地層評價、目標層地質模型建立、導向標志層的選取及模擬曲線對比等方面入手，確定鉆頭上下傾鉆進方向及在目標層中的位置，以實時調整井眼軌跡，使其盡可能在儲層物性較好的部位延伸。
  5. Application of lwd curves in following tracks of geologic object

    曲線在隨鉆跟蹤地質目標中的應用
  6. Moreover, because pressure prediction is another important application of lwd, formation pressure prediction is researched which is base on lwd

    此外隨鉆地層壓力預測是lwd的另一個重要工程應用，為此本文進行了基於隨鉆測井資料的地層壓力預測方法研究。
  7. Firstly, interpretation method of lwd is researched. logging interpretation while drilling includes lithological interpretation, formation parameters interpretation and oil interpretation while drilling etc. information of lwd should be disposed and standardized before lwd is interpreted

    論文首先開展了lwd資料的解釋方法研究。隨鉆測井資料解釋方法包括隨鉆地層巖性解釋方法、隨鉆地層參數解釋方法和隨鉆地層含油氣性解釋方法等。
  8. Lwd : long way of design measured from center of bond to center of bond

    長節距：從節點中心到節點中心的長的菱形對角線的長度。
  9. In the same time, application of lwd is reseached too

    同時論文也對lwd資料的工程應用進行了方法研究。
