摘要:
鄂尔多斯盆地西缘中生界长8、长9段由于物性差、流体性质复杂,测井响应显示油水电性特征差异小、对比度低,高电阻率水层的存在给油水识别带来极大困难,测井解释符合率低。研究明确了盆地西缘高电阻率水层主要受古油藏破坏后的氧化残余油和地层水矿化度的影响。针对氧化残余油“重碳轻烃”的特性,基于不同测井方法的原理差异,结合体积模型,建立了氧化残余油定量表征方法。在此基础上,通过实测地层电阻率与校正后电阻率的比值进行流体性质识别,该比值降低了地层水矿化度及氧化残余油对储层电阻率的影响,实现了流体性质的准确识别。研究对于鄂尔多斯盆地西缘低对比度储层的流体性质识别提出了新的思路和方法,提高了测井解释符合率,具有应用价值和推广意义。
Abstract:
Due to the poor physical properties and complex fluid properties of Chang 8 and Chang 9 members of Mesozoic in the western margin of Ordos basin, logging response shows that the oil-water electrical characteristic difference is small, low contrast, the presence of high resistivity water layer brings great difficulties to oil-water identification, log interpretation coincidence rate is low. The study shows that the high resistivity water layer in the western margin of the basin is mainly affected by the oxidized residual oil and formation water salinity after the destruction of the ancient reservoir. According to the characteristics of heavy carbon light hydrocarbon of oxidized residual oil, based on the principle difference of different logging methods and combined with volume model, a quantitative characterization method of oxidized residual oil was established. On this basis, the ratio of measured formation resistivity to corrected resistivity is used to identify fluid properties. This ratio reduces the influence of formation water salinity and oxidized residual oil on reservoir resistivity and achieves accurate identification of fluid properties. This paper puts forward a new idea and method for the identification of fluid properties in such low contrast reservoirs, which can effectively improve the coincidence rate of log interpretation and has application value and popularization significance.
