南阳地区泌阳凹陷沉积相展布与油气勘探
Facies distribution and petroleum exploration in Biyang sag of Nanyang area
摘要
Abstract
According to seismic, well-logging and core data, the micro-facies and type of the third Member of Paleogene Hetaoyuan Formation in Bidian area of Biyang sag were determined on the basis of sedimentary * structures, lithological textures of profiles and thicknesses of sandstone bodies. Using the new methods for seismic inversion, the authors obtained the thickness of the iso -chronological single sandstone body and drew the distribution map of sedimentary micro-facies by tracing thin sandstone reservoirs from three-dimensional data. It is shown that there exist widely-distributed deposits of turbidite fans and sliding turbidite fans characterized by the turbidity -flows sediments, and sedimentary frameworks of north and south turbidite fans interbedded with the deep -water lacustrine sediments at the center. Sedimentary evolution, rich early turbidite sandstones and late deep-water mudstones suggest relative rise of the lacustrine level. In the light of favorable facies zones, the authors predicted and evaluated subtle traps of the sag, thus providing a basis for petroleum exploration.关键词
