Sedimentary Features and Distribution of High-Quality Reservoirs in the Ledong Area, Yinggehai Basin ()
ABSTRACT
The Ledong-30 area is located in the southern part
of the central depression of the Yinggehai basin, where the exploration
activity aims to gas in the middle and deep strata is started lately. The
previous studies on the sedimentary system and main controlling factors of
reservoir formation are mainly focused on the middle and shallow strata above
the Huangliu Formation. Based on a fine interpretation of seismic data, the sedimentary characteristics,
internal structures, and distribution rules of submarine fans and gravity flow
channels in the Ledong-30 area are analyzed in this
paper. In addition, the dynamic migration processes of their planar
distribution and the vertical evolution law (vertical sequence combinations and
superposition features of turbidity events) are also addressed. At last, the
internal structural characteristics of the gravity flow system and
comprehensive formation mechanisms of the large-scale gravity flow sediments (turbidities
fans) are also been analyzed, which is helpful for the prediction of favorable reservoir distribution. The
results can be used directly to guide oil and gas exploration in the Ledong
area of the Yinggehai basin.
