【摘要】 火成岩具有极强的非均质性,对火成岩的识别是油气勘探的难题之一,特别是在某些岩层中混入了火成岩将会影响油气藏的后期保存及圈闭落实的可靠性。以新疆托甫台地区为例,运用测井曲线中的自然伽马曲线、声波曲线和密度曲线,结合波阻抗反演及地震相等方面的知识识别火成岩。更多还原

【Abstract】 The igneous rock has the property of strong anisotropism.The identification of the igneous rock is one of the challenges the oil-gas exploration faces.The interfusion of the igneous rocks in some rock stratums will affect the later preservation of the oil-gas reservoir and the reliability of the entrapment.However,with the further research on exploration at home and abroad,the igneous reservoirs have been successively discovered,consequently,scholars and scientists pay more and more attention to the project of identifying and predicting the igneous reservoirs.Taking the Tofutai region of Xinjiang as an example,this paper investigates the identification of the igneous rocks by the use of the natural gamma ray curves,acoustic curves and density curves in the well logs,together with the knowledge of impedance inversion and seismic phase.更多还原
