1、聲波變密度測井技術(shù)及□井質(zhì)量評價方法應(yīng)用馮嘯辰摘要隨若套管井測井技術(shù)應(yīng)川內(nèi)若多元化發(fā)展,聲波變密度測井在油UI監(jiān)測M井質(zhì)最方而土耍采川聲幅測井和聲波變密度測井。通過對聲波理論研宄深入,聲波信息與巖層參數(shù)關(guān)系的研宄,數(shù)字測井技術(shù)和測并資料數(shù)據(jù)處理技術(shù)的發(fā)展,設(shè)計了盧波全波列測并。盧波全波列測并不僅能夠通過盧幅及膠結(jié)指數(shù)(BT值)曲線對袞管與水泥的膠結(jié)進行評價,而且能夠依據(jù)VDL圖像對水泥與地層的膠結(jié)進行評價,從而克服了普通聲幅測井的片面性,提高了解釋的可靠性。既能反映一界面膠結(jié)狀況,又能提供二界面膠結(jié)信息。本文首先闡述丫聲波變密度測井原理及儀
2、器技術(shù)原理,然后結(jié)合聲波變密度測井屮一些典型實例資料進行丫剖析,針對影響固井質(zhì)覺測井的因素提出丫對各種干擾的判斷和解決力‘法,對不同固井質(zhì)覺作出評價解釋:在此基礎(chǔ)上探究盧波變密度測并技術(shù)優(yōu)缺點。最后,以期提搞人們對盧波變密度水泥膠結(jié)測井技術(shù)的認(rèn)識程度,提髙其資料綜合利用價位。關(guān)鍵詞聲波變密度測井W井質(zhì)景評價水泥膠結(jié)測井測井解釋VariableDensityAcousticLoggingTechnologyAndQualityEvaluationMethodAppliedCementingAbstractWiththecasedholelog
