【摘要】：致密砂巖油藏作為一種非常規(guī)油氣資源,已經(jīng)成為研究的重點(diǎn)區(qū)域。相對(duì)于常規(guī)油藏物性好、孔滲相關(guān)性強(qiáng)的特點(diǎn),致密砂巖油藏儲(chǔ)層的物性差,測(cè)井響應(yīng)特征相對(duì)不明顯,因此有必要結(jié)合錄井對(duì)致密砂巖油藏的油水層綜合評(píng)價(jià)進(jìn)行研究。建立一套適用于研究區(qū)致密砂巖油氣藏儲(chǔ)層的測(cè)、錄井識(shí)別技術(shù)與方法,以便更好地為油藏探勘開發(fā)服務(wù)。 在地質(zhì)規(guī)律認(rèn)識(shí)的基礎(chǔ)上,利用巖心刻度常規(guī)測(cè)井,分層段總結(jié)出各類儲(chǔ)層的測(cè)井響應(yīng)特征,建立了不同類型儲(chǔ)層的測(cè)井識(shí)別模式。常規(guī)測(cè)井能夠較容易地劃分、識(shí)別出研究區(qū)較好儲(chǔ)層。對(duì)于常規(guī)測(cè)井特征不明顯的較差儲(chǔ)層,則應(yīng)結(jié)合錄井顯示資料來(lái)綜合識(shí)別。根據(jù)壓汞、核磁和水膜厚度等實(shí)驗(yàn)分析資料；常規(guī)測(cè)井資料以及生產(chǎn)動(dòng)態(tài)資料,綜合分析來(lái)確定了儲(chǔ)層參數(shù)下限值。在物性參數(shù)下限確定的基礎(chǔ)上,再結(jié)合測(cè)井資料確定了儲(chǔ)層的電性下限,建立了儲(chǔ)層有效性分類評(píng)價(jià)標(biāo)準(zhǔn)。以巖樣孔、滲、飽分析數(shù)據(jù),不同溫壓條件下的巖電測(cè)試數(shù)據(jù)為基礎(chǔ),開展巖心刻度測(cè)井,并建立巖石物性參數(shù)測(cè)井計(jì)算模型,其次應(yīng)用地化錄井資料,通過(guò)不同取樣方式的篩選建立了地化參數(shù)測(cè)井評(píng)價(jià)經(jīng)驗(yàn)公式,最終建立了測(cè)井與錄井參數(shù)之間的關(guān)系,且相關(guān)性較好。 針對(duì)致密砂巖油藏儲(chǔ)層巖性致密、物性差等特點(diǎn),在測(cè)井響應(yīng)特征的基礎(chǔ)上,結(jié)合氣測(cè)、地化及定量熒光三種錄井方法,來(lái)綜合分析其圖譜響應(yīng)特征及探索適應(yīng)于研究區(qū)的圖版方法,以蘇北盆地高郵凹陷阜寧組致密砂巖油藏為例,進(jìn)行綜合評(píng)價(jià)油水層方法研究。在確定的測(cè)錄井綜合評(píng)價(jià)油水層方法的基礎(chǔ)上,對(duì)研究區(qū)鉆井、錄井顯示好而測(cè)井曲線無(wú)反映和鉆井、錄井顯示好并且測(cè)井曲線也反映好的實(shí)例做應(yīng)用分析,發(fā)現(xiàn)此綜合評(píng)價(jià)方法結(jié)果與試油資料相吻合。 本論文的完成為蘇北盆地高郵凹陷阜寧組致密砂巖儲(chǔ)層測(cè)、錄井結(jié)合識(shí)別及儲(chǔ)層有效性評(píng)價(jià)提供了一套切實(shí)可行的方法,同時(shí)也為下一步勘探開發(fā)提供了更加可靠的測(cè)、錄井解釋依據(jù)。
[Abstract]:As an unconventional oil and gas resource, tight sandstone reservoir has become a key area of research. Compared with conventional reservoir, the physical property of tight sandstone reservoir is poor, and the logging response is not obvious. Therefore, it is necessary to study the comprehensive evaluation of oil-water reservoir in tight sandstone reservoir by combining logging with the characteristics of good physical property and strong correlation between pore and permeability. A set of techniques and methods for logging and logging identification of tight sandstone reservoirs in the study area are established in order to better serve reservoir exploration and development. Based on the understanding of geological laws, the logging response characteristics of various reservoirs are summarized by using core calibration routine logging and stratified section, and the logging identification patterns of different types of reservoirs are established. Conventional logging can be easily divided to identify better reservoirs in the study area. For the poor reservoir which is not obvious in the conventional logging data, the logging data should be combined to identify the reservoir comprehensively. According to the experimental data of mercury injection, nuclear magnetic field and water film thickness, conventional logging data and production performance data, the lower limit values of reservoir parameters are determined by comprehensive analysis. Based on the determination of the lower limit of physical parameters and well logging data, the lower limit of electric property of reservoir is determined, and the criteria of classification and evaluation of reservoir effectiveness are established. Based on the sample pore, seepage, saturation analysis data and rock electrical test data under different temperature and pressure conditions, the core calibration logging is carried out, and the log calculation model of rock physical parameters is established. Secondly, geochemistry logging data are used. Through the screening of different sampling methods, the experiential formula of geo-chemical parameter logging evaluation is established, and the relationship between logging and logging parameters is established, and the correlation is good. In view of the characteristics of tight lithology and poor physical properties of tight sandstone reservoir, based on the response characteristics of logging, combined with three logging methods, gas logging, geochemistry and quantitative fluorescence, In order to comprehensively analyze the characteristics of its map response and explore the plate method suitable for the study area, taking the dense sandstone reservoir of Funing formation in Gaoyou depression of Subei Basin as an example, the comprehensive evaluation method of oil-water layer is studied. On the basis of the method of comprehensive evaluation of oil and water layer by logging, the examples of well logging showing well but logging curve not reflecting and drilling, well logging showing well and logging curves reflecting well are analyzed. It is found that the result of this comprehensive evaluation method is in agreement with the test data. The completion of this paper provides a set of feasible methods for logging of dense sandstone reservoir in Funing formation in Gaoyou Sag, Subei Basin, combining logging with identification and evaluation of reservoir effectiveness, and provides a more reliable survey for further exploration and development. Mud logging interpretation basis.
