Abstract

By studying the lithology, structure, sedimentary structure, sedimentary sequence, and character of electrical property of the lithosomic body, the sedimentary facies of Fu1 and Fu2 Member in Matouzhuang oilfield are classified. The sedimentary models of all facies are established, and the evolution of them is analyzed. There are delta front intrafacies in Fu1 Member, and frontal sand sheet, mouth bar, distributary channel under water, bay between distributary channels under water, and natural levee under water occur from bottom to top. It is characteristic of progradation of delta. Delta front intrafacies vanishes at the end of the sedimentation of Fu1 member. There are offshore shallow lacustrine intrafacies in Fu2 Member, including the subdivided facies of organic beach, oolitic beach, calcareous beach, sandy bar in shallow lake, and mud in offshore shallow lake. Classifying the type of carbonatite beach by lithology makes its name simple and concrete. In Fu2 Member, there are two sedimentary models of wide shallow lake sand bar and carbonatite beach in uplifted area underwater.
