摘要
By analyzing synthetically the core and logging data,this paper summarizes the response law of igneous rocks in logging curve and the logging idebtification criterion of lithology.On basis of the logging difference between the igneous and sedimentary rocks,the times and types of volcanic activity of the first member of Shahejie Formation in Shanghe Region are analyzed.It is considered that the volcanic activity can be divided into six phases in the first member of Shahejie Formation in Shanghe Region,belonging to underwater eruptions in shallow water.On this basis,this paper studies the distribution of volcanic rock in each period,summarizes the distribution mode and advantageous reservoir facies belt by synthetically using the time slice of coherent data volumes,3D seismic data and logging data interpretation.The subfacies of near and far volcanic vents are considered to be favorable reservoir facies belt,which provides the necessary geology basis for oil and gas exploration of volcanic reservoir in Shanghe Region.
