【摘要】：三塘湖盆地位于準(zhǔn)噶爾大型含油氣盆地邊緣,上二疊統(tǒng)蘆草溝組地層有機(jī)質(zhì)豐度高,生烴潛力大,是優(yōu)質(zhì)烴源巖的有利發(fā)育部位。蘆草溝組地層巖性復(fù)雜、儲(chǔ)集性能變化大,陸相、海相雙重沉積特征并存,給油氣勘探帶來(lái)了較大的難度。本文針對(duì)三塘湖盆地致密油烴源巖,以測(cè)井資料為主要手段,研究蘆草溝組、條湖組地層的烴源巖特征及其差異,進(jìn)行烴源巖的定性識(shí)別與定量計(jì)算,結(jié)合有效烴源巖的分布,探索了蘆草溝組和條湖組地層之間的源儲(chǔ)配置關(guān)系。蘆草溝組地層在牛圈湖構(gòu)造帶和馬中構(gòu)造帶巖性差異大、且成分復(fù)雜、巖性變化大。對(duì)巖石物理及地球化學(xué)實(shí)驗(yàn)資料研究顯示,蘆草溝組烴源巖品質(zhì)佳,其中牛圈湖構(gòu)造帶優(yōu)勢(shì)烴源巖為白云巖和泥巖,馬中構(gòu)造帶為沉凝灰?guī)r。相對(duì)而言相,條湖組烴源巖品質(zhì)較差,烴源巖巖性較為單純,以泥巖和凝灰?guī)r為主。與非烴源巖相比,烴源巖具有較高的聲波時(shí)差、中子孔隙度和電阻率,而密度較小。本文基于上述測(cè)井資料,分別采用判別函數(shù)法、交會(huì)圖法和△LgR法可以將烴源巖較好識(shí)別。采用聲波時(shí)差和電阻率測(cè)井資料,分別針對(duì)不同層組、不同構(gòu)造帶,建立了基于改進(jìn)的△LgR的TOC(有機(jī)質(zhì)含量)計(jì)算方法和利用電阻率、三孔隙度多信息融合的TOC計(jì)算方法,取得了較好的應(yīng)用效果。利用吸附烴含量(S_1)與TOC建立有效烴源巖的判定標(biāo)準(zhǔn)和下限,確定了蘆草溝組有利的烴源巖發(fā)育帶主要在二段。同時(shí),以實(shí)際生產(chǎn)資料為基礎(chǔ),綜合分析地質(zhì)地震資料,根據(jù)油源對(duì)比的分析結(jié)果,得到了條湖組油層主要來(lái)源于蘆草溝組優(yōu)質(zhì)烴源巖,以斷層為運(yùn)移通道的源儲(chǔ)配置關(guān)系。
[Abstract]:Santanghu basin is located at the margin of Junggar large hydrocarbon bearing basin. The upper Permian Lucaogou formation has a high abundance of organic matter and great hydrocarbon generation potential. It is a favorable position for the development of high quality source rocks. The lithology of Luchaogou formation is complicated, the reservoir performance changes greatly, and the dual sedimentary characteristics of continental and marine facies coexist, which brings great difficulty to oil and gas exploration. Based on logging data, the characteristics and differences of source rocks in Lucaogou formation and Tianhu formation are studied in this paper. The source rocks are qualitatively identified and quantitatively calculated, combined with the distribution of effective source rocks. The relationship between source reservoir allocation of Lucaogou formation and Tianhu formation is explored. The lithology of Lucaogou formation in Niuquan Lake structural belt and Mazhong tectonic zone is very different, and its composition is complex, and its lithology changes greatly. The physical and geochemical experimental data show that the source rocks of the Lucaogou formation are of good quality, and the dominant source rocks in the Niuquan Lake structural belt are dolomite and mudstone, and the mazhong structural belt is sedimentary tuff. Comparatively speaking, the source rocks of Tianhu formation are of poor quality and simple lithology, mainly mudstone and tuff. Compared with the non-source rocks, the source rocks have higher acoustic moveout, neutron porosity and resistivity, but lower density. Based on the above logging data, the discriminant function method, cross plot method and LgR method can be used to identify the source rocks. Based on the sonic time difference and resistivity logging data, the TOC (organic matter content) calculation method based on the improved LgR and the TOC calculation method based on the information fusion of resistivity and three porosity are established for different layers and different structural zones, respectively. Good results have been obtained. The criterion and lower limit of effective source rock were established by using S- 1 and TOC. The favorable source rock development zone of Luchaogou formation is mainly in the second member. At the same time, based on the actual data of production and comprehensive analysis of geological and seismic data, according to the analysis results of oil source correlation, it is obtained that the reservoir of Tianhu formation mainly comes from the high quality source rock of the Lucaogou formation, and the relationship of source storage and configuration of the fault as the migration channel is obtained.
