【摘要】：近年來(lái),在新疆準(zhǔn)噶爾盆地瑪北斜坡區(qū)百口泉組多口井獲得了工業(yè)油流,夏子街扇體西翼整體連片油氣藏群,顯示出了百口泉組良好的油氣勘探前景。瑪北斜坡區(qū)百口泉組地層為扇三角洲沉積,砂礫巖儲(chǔ)層縱向上多期扇體疊置,橫向巖性及厚度變化大,儲(chǔ)層非均質(zhì)性強(qiáng),孔隙類(lèi)型以剩余粒間孔、粒內(nèi)溶孔為主,為低孔低滲特征。這一特點(diǎn)使利用測(cè)井資料和地震資料進(jìn)行優(yōu)質(zhì)儲(chǔ)層預(yù)測(cè)存在很大問(wèn)題。針對(duì)百口泉組儲(chǔ)層發(fā)育地質(zhì)特點(diǎn),采取多種地震技術(shù)手段和方法進(jìn)行了分析和研究。首先通過(guò)地質(zhì)錄井、巖心觀察、薄片分析資料,確定與巖性反映敏感的常規(guī)測(cè)井響應(yīng)參數(shù)--電阻率。在明確儲(chǔ)層特征的前提下,在諸多儲(chǔ)層預(yù)測(cè)方法中,通過(guò)比較分析,優(yōu)選了地震相、地震多屬性分析和地質(zhì)統(tǒng)計(jì)學(xué)電阻率反演、多屬性融合等技術(shù)手段對(duì)百口泉組砂礫巖優(yōu)質(zhì)儲(chǔ)層進(jìn)行預(yù)測(cè)。最后通過(guò)采用地震相和地質(zhì)統(tǒng)計(jì)學(xué)協(xié)模擬的電阻率以及波阻抗三種屬性相融合的技術(shù),有效的預(yù)測(cè)了本區(qū)的有利儲(chǔ)層分布,刻畫(huà)了本區(qū)三類(lèi)儲(chǔ)層及泥巖的分布范圍;通過(guò)項(xiàng)目研究,形成了一套針對(duì)本地區(qū)百口泉組砂礫巖優(yōu)質(zhì)儲(chǔ)層預(yù)測(cè)行之有效的技術(shù)手段,也為瑪北斜坡區(qū)控制儲(chǔ)量的計(jì)算和油氣藏的描述提供了可靠的、重要的依據(jù)。
[Abstract]:In recent years, industrial oil flow has been obtained in many wells of Baikouquan formation in Mabei slope area of Junggar Basin, Xinjiang, and the whole connected oil and gas reservoir group in the west wing of Xiazijie fan body shows a good prospect for oil and gas exploration in Baikouquan formation.The formation of Baikouquan formation in Mabei slope area is fan-delta sedimentary, and the sand gravel reservoir is overlapped in many stages in longitudinal direction. The lateral lithology and thickness change greatly, the reservoir heterogeneity is strong, and the pore type is mainly residual intergranular pore and intragranular dissolved pore.It is characterized by low porosity and low permeability.This feature makes it difficult to use logging data and seismic data to predict high quality reservoir.According to the geological characteristics of reservoir development in Baikouquan formation, various seismic techniques and methods are adopted to analyze and study.Firstly, through geological logging, core observation and thin slice analysis, the conventional logging response parameter-resistivity, which is sensitive to lithology reflection, is determined.On the premise of defining reservoir characteristics, seismic facies, seismic multi-attribute analysis and geostatistical resistivity inversion are selected through comparative analysis in many reservoir prediction methods.Multi-attribute fusion is used to predict the high-quality sand-gravel reservoir of Baikouquan formation.Finally, by using the technique of combining the resistivity and wave impedance of seismic facies and geostatistical cosimulation, the favorable reservoir distribution in this area is predicted effectively, and the distribution range of three types of reservoirs and mudstone in this area is described.Through the project research, a set of effective technical means for prediction of high quality sand and gravel reservoirs of Baikouquan formation in this area has been formed, which also provides a reliable and important basis for the calculation of controlled reserves and the description of oil and gas reservoirs in the Mabei slope area.
