Sedimentary facies and favorable area of hydrocarbon accumulation of the Paleogene Shahejie Formation in northern Lixian Slope of Raoyang Sag in central Hebei Province

There is a great quantity of hydrogen sulphide in oil and gas traps in Jinxian depression, central Hebei Province.

Discovery of Dacheng large coal gas field and its meaning;

Logging Interpretation Practice and Understanding of Marlite Reservoir in Shulu Sag,Jizhong Depression;

Reservoir-forming Pattern of Complex Fault-block Oil Reservoirs in Jizhong Depression;

New concept of exploration strategy for the oil-rich Jizhong Depression;

More than 200 of formation tests(or the third open to swab)and conventional oil testing to these formations have been done during over ten years of practice in Huabei oilfield, Jizhong region.

There are two kinds of oil supply ways in the Tertiary clastic rock oil reservoirs in Jizhong Region:one is fractured surface supply oil;the other is bedded permeable layer supply oil.

Coupling Relationship Between Structure and Sedimentation in the North of Jizhong Basin During Paleogene;

The Jizhong basin is one of the half-g raben group in the northwestern Bohai Bay basin,mostly developed in the Paleogene,and is fa mous for its buried hill-type hydrocarbon accumulation.

Terrigenous sedimentary rocks developed with a great thickness in the rift basin of the South Jinxian Sag, Jizhong Basin, and stratigraphic framework is sandy sediments.

The Geophysical Prospecting Company has carried out tests and researches on high resolution 2D seismic methods and techniques for three years for Lixian Slope and Wenan Slope in central Hebei area and for the eastern and western hollow trough in Honghaoershute sag in Erlian area.
