【摘要】：针对现有流体性质识别方法在准噶尔盆地中拐凸起石炭系应用的不适用性和不确定性问题,运用视地层水电阻率分布法和核磁差谱-气测烃类比法进行流体判别。研究结果表明,中基性火山岩储层含油性越好,视地层水电阻率分布越靠后,核磁差谱孔隙度越大,烃类特征比大于0.5,研究区油气层测井解释符合率由50%提高至90%。研究成果对识别石炭系油层、指导试油选层有重要意义。
[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.
