Application of wavelet transform to improving the vertical resolution of logging while drilling wave propagation resistivity 應用小波分析改善隨鉆電阻率測量的縱向分辨率
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(yè)的不斷發(fā)展,大斜度井、分支井和水平井等鉆井技術(shù)越來越多地被用來開發(fā)規(guī)模更小、油層更薄、物性更差、非均質(zhì)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,然后從隨鉆測井、錄井資料中提取與巖性密切相關(guān)的參數(shù),建立測井相-巖相統(tǒng)計模式,并采用灰色關(guān)聯(lián)識別方法實時判別地層巖性;采用直井的參數(shù)解釋方法進行隨鉆地層參數(shù)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,并結(jié)合地質(zhì)、錄井資料進行隨鉆地層含油氣性評價。
