摘要:
滄東凹陷孔二段發育一套細粒沉積巖,巖性多為碎屑沉積和化學沉積的過渡性巖類,巖性極其復雜、礦物成分多樣、縱向變化快,常規巖性識別方法無法進行有效識別,礦物成分的定量評價困難。在官××井500 m系統取心及配套的巖石物理實驗分析基礎上,提取巖性敏感曲線,建立了適合于細粒沉積相區的多參數融合逐步巖性識別方法;并針對老井及多井的巖性識別開展基于測井相的巖性識別方法研究,形成了孔二段不同層位測井相與巖心的數據庫,利用多參數融合逐步巖性識別方法與所建立的測井相巖心數據庫有效地解決了孔二段細粒沉積相區巖性從定性到定量、到多井的識別難題。
Abstract:
Fine sedimentary rocks developed in the Kong 2 Formation in the Cangdong depression are mostly transitional clastic and chemical deposits. The lithology is extremely complex, the mineral composition is diverse, and the longitudinal continuity is poor. It is difficult to identify the lithology using conventional methods, and to evaluate the mineral composition quantitatively. Based on the cores taken at 500 m in well Guan ×× and supporting petrophysical experiments, this paper extracts lithology-sensitive logging curves and develops a step-by-step lithologic identification method for the fine sedimentary facies, and then carries out researches on lithologic identification methods based on the logging facies in old wells and multiple wells, and finally establishes a logging facies and core database for the Kong 2 Formation. The step-by-step lithologic identification method and the log facies and core database can effectively identify the lithology from qualitative to quantitative to multiple wells in the fine sedimentary facies zone of the Kong 2 Formation.
