沉积微相研究技术在油田开发中的应用

Application of Sedimentary Microfacies Study in Development of Oilfield

在油田勘探开发不同阶段,对不同类型的油藏进行的沉积相研究的内容和方法是不同的。开发阶段以地质、测井、钻井和油田生产动静态资料为依据,研究油藏内不同开发小层的砂体大小、形态和分布。结合鄯勒油田七克台组沉积相的研究,总结了开发阶段油藏描述过程中沉积相研究的方法及应用,包括宏观沉积相及沉积环境研究、沉积微相类型及其沉积特征以及沉积微相的平面展布特征等方法,这些方法对地质条件复杂、开发难度大的断块油田的开发具有参考价值。

At various stages of exploration and development of oilfield, methods for sedimentary facies study of various reservoirs are different. Combining sedimentary facies study for J2q of Shanle oilfield, sedimentary facies study methods and application in reservoir description at development stage, including macro - sedimentary facies and sedimentary setting study, sedimentary microfaeies types and characteristics, plane distribution of sedimentary mierofaeies etc. are summarized. The methods are good references for the development of fault block oilfield with complicated geological condition and development difficulty.
