【摘要】：針對(duì)現(xiàn)有流體性質(zhì)識(shí)別方法在準(zhǔn)噶爾盆地中拐凸起石炭系應(yīng)用的不適用性和不確定性問題,運(yùn)用視地層水電阻率分布法和核磁差譜-氣測(cè)烴類比法進(jìn)行流體判別。研究結(jié)果表明,中基性火山巖儲(chǔ)層含油性越好,視地層水電阻率分布越靠后,核磁差譜孔隙度越大,烴類特征比大于0.5,研究區(qū)油氣層測(cè)井解釋符合率由50%提高至90%。研究成果對(duì)識(shí)別石炭系油層、指導(dǎo)試油選層有重要意義。
[Abstract]:In view of the inapplicability and uncertainty of the existing identification methods of fluid properties in Carboniferous system of the Guigai uplift in Junggar Basin, the method of apparent formation water resistivity distribution and the method of differential nuclear magnetic spectrum gas hydrocarbon ratio are used to distinguish the fluid.The results show that the better the oil content of the middle basic volcanic reservoir, the greater the porosity of the formation water resistivity distribution, the larger the nuclear magnetic difference spectrum porosity, the greater the hydrocarbon characteristic ratio is, and the higher the interpretation coincidence rate of the oil and gas reservoir logging is from 50% to 90%.The research results are of great significance in identifying Carboniferous reservoirs and guiding oil test and selection.
