摘要:
基于委内瑞拉奥里诺科重油带地质资料、岩石物理实验资料,在综合分析地层水成因的基础上,发现研究区存在2种不同矿化度的地层水,即高矿化度束缚水(原生水)和低矿化度混合水(次生水),地层水矿化度受束缚水和混合水矿化度、体积比共同影响。针对研究区地层水矿化度变化规律的复杂性,应用改进的双水模型计算饱和度,通过与传统固定地层水电阻率的阿尔奇模型对比,改进的双水模型计算结果与实验室岩心分析结果吻合更好,且计算结果明显优于传统模型,验证了该方法的准确性与适用性。应用该方法对研究区48口井进行了精细解释,并制作了油藏横剖面对比图,明确了研究区冲刷带的纵向分布规律,对研究区超重油储层射孔方案优化以及开发方案的制定具有重要指导意义。
Abstract:
Based on the geological data and petrophysical experiment of the Orinoco heavy oil zone in Venezuela as well as a comprehensive analysis of the formation water it was found that there were two types of formation water with different salinities in research area:the high salinity bound water(connate water)and the low salinity mixed water(secondary water). The salinity of formation water was influenced by the combination of bound water mixed water salinity and volume ratio. Considered the complexity of formation water salinity in the study area the improved dual-water model was used to calculate the water saturation. Compared with traditional Archie's model the calculated results of the dual-water model were in good agreement with the results of the laboratory core analysis and significantly better than the result of traditional model which verified the accuracy and applicability of the improved method. This method has been used to finely interpret 48 wells in the study area and a reservoir cross-sectional comparison chart was made. Based on the result the vertical distribution of the scouring zone in the study area was clarified which has important significance for the optimization of the perforation and the formulation of development plan for the heavy oil reservoir in the study area.
