摘要
川中磨溪—龙女寺构造带下三叠统嘉陵江组碳酸盐岩储层岩性种类较多,夹有石膏层且储层普遍含水,使得流体的判识比较困难。另外,嘉陵江组流体分布规律不明显,控制因素复杂。在深入分析不同流体测井响应特征的基础上,用定性和定量2种方法对流体性质进行判识,建立起适合于研究区的流体判识模型。然后,对流体分布特征进行分析,并对影响流体分布的控制因素加以探索,认为储层物性和构造幅度是控制流体分布的主控因素,而储层内部较强的非均质性是造成流体分布复杂的原因。
The categories of the carbonate rock reservoirs are complicated in the Lower Triassic Jialingjiang Formation of Moxi-Longnvsi Structure Belt in central Sichuan. The reservoirs have gesso interlayers and formation water, which makes the identification of liquid difficult. In addition, the distribution regulation of liquid in Jialingjiang Formation is not clear and the controlling factors are also complex. Based on the analysis of the log response characteristics of different liquids, this paper tries to distinguish liquid by qualitative and quantitative method and sets up identification model that is suitable for study area. It also tries to analyze the distribution characteristics of the liquid and seek after the factors that influence on liquid distribution. It is considered that the quality of reservoir and the fluctuation of structure are key factors that control the liquid distribution and the intense heterogeneity of reservoir is the reason that results in the complex liquid distribution.
