【摘要】：近年來沈陽采油廠大民屯潛山水平井在開發(fā)過程中遇到各種油氣顯示與產(chǎn)能非相關(guān)的問題。通過探索和總結(jié)相應(yīng)的錄井解釋評價方法,形成油氣顯示與產(chǎn)能二者之間的規(guī)律性認識。為甲方勘探和開發(fā)以及指導(dǎo)今后的錄井工作提供可靠的依據(jù),為配產(chǎn)方案編制尋找有利井網(wǎng)或優(yōu)化油氣層開發(fā)層系,延長油井投產(chǎn)周期,提高單井產(chǎn)油量提供支持。本文通過對現(xiàn)場巖屑、氣測、地化、定量熒光等錄井技術(shù)進行研究,綜合分析各方法的應(yīng)用效果,對各方法進行有機結(jié)合;通過定量熒光、地化等參數(shù)及譜圖區(qū)分巖屑顯示及鉆井液污染情況,通過元素分析、巖心實物標準定樣,DC指數(shù)參考等方法對潛山巖性進行辨別,對儲層類別進行區(qū)分,效果良好。研究了靜水壓力壞境下氣測值的變化情況,提出了“全烴恢復(fù)值--鉆時”交匯解釋方法,將物性、含油性創(chuàng)新性的有機結(jié)合,解決了過平衡鉆井消弱顯示帶來的解釋難題。本文提出了鉆時,鉆速曲線重疊交匯法,比以往錄井單純的鉆時,全烴評價儲層的方法全面,采用了曲線重疊交匯技術(shù),加入DCS指數(shù)來識別潛山剛性體的可鉆性的變化,輔助峰基比來確認含油性。
[Abstract]:In recent years, the horizontal well of Damingtun buried hill in Shenyang oil production plant has encountered various problems of oil and gas display not related to productivity in the course of development. By exploring and summarizing the corresponding mud logging interpretation and evaluation methods, Forming a regular understanding between oil and gas display and productivity, providing a reliable basis for Party A's exploration and development and guiding future logging work, searching for favorable well pattern for production planning or optimizing the development layer system of oil and gas reservoir, and providing a reliable basis for Party A's exploration and development as well as guiding the logging work in the future. In this paper, the mud logging techniques such as cuttings, gas logging, geochemistry and quantitative fluorescence are studied, the application effect of each method is analyzed synthetically, and the organic combination of each method is carried out. The lithology of buried hill is distinguished by quantitative fluorescence, geochemistry and spectral diagram. The lithology of buried hill is distinguished by element analysis, reference of core standard sample and DC index, and reservoir classification. The effect is good. The change of gas measurement value under the bad hydrostatic pressure is studied, and the method of "total hydrocarbon recovery value-drilling time" is put forward, which combines the organic combination of physical property and oil content innovation. In this paper, the overlapping intersection method of drilling velocity curve is proposed, which is more comprehensive than the simple drilling method in mud logging, and the method of curve overlapping intersection is adopted. The DCS index is added to identify the drillability of the buried hill rigid body, and the ratio of peak to base is used to confirm the oil content.
