Overview of research into formation mechanism and distribution law of stratigraphic reservoir
Online published: 2009-12-16
The importance of stratigraphic reservoir exploration is rising day by day on the condition that the field of national oil and gas exploration is transferred fromstructural reservoir to litho-stratigraphic reservoir. On the basis of the former research, this paper centers on the unconformity and classifies the stratigraphic trap into three types: the on- lapping typed trap above the unconformity, the barrier typed trap belowthe unconformity and the truncation type of trap between the former unconformity and the later unconformity according to the difference of trap mechanism. This paper summarizes the formation mechanism of stratigraphic reservoir from the strength and the structure of the unconformity. Furthermore, authors point out the distribution law of different type of stratigraphic reservoirs and exploration suggestion for different type of stratigraphic reservoirs. Finally, this paper points out some theories and techniques which are in great need for stratigraphic reservoir exploration.
