Because of the separation of Chenjia reverse fault(F 1),two obviously different geological zones in structure and depositional features in Lengjia region are produced.

Tectonic positive inversion of Chennan Fault and its relation with hydrocarbon accumulation in Dongying Sag

In order to find out the location,characteristics and activities of the Laoyachen Fault in Zhengzhou,the high-resolution shallow seismic P and S wave survey profiling across the Laoyachen Fault was carried out at the end of 2006,and different seismic sources along with combinations of diverse observation geometries with different parameters were used.

In order to find out the location, characteristics and activities of Zhengzhou Laoyachen fault, the shallow seismic surveys at different exploration depths that are across Laoyachen fault in northern area of Zhengzhou city, were carried out in 2006.

Based on the research on relationship between Mangshan scarp and Laoyachen fault,and according to interpretation of remote sensing images,middle-shallow layer seismic detecting and comparison of joint drillings,measureme.

Research on Majiaheba thrust fault in Leibo of Sichuan;

A study on mechanical mechanism on development of thrust fault;

Geological characteristics of Wengeng thrust fault in Langshan area of western Inner Mongolia

They are characteri zed by thrust and southward dip.

Yingjisu subsidence of the Meso - Cenozoic was a piggyback foreland basin that developed on the base of fold - thrust belts of the Paleozoic.

Fluid veins widely developed in the Daqingshan thrust-nappe,and can be divided into filled veins and edged veins according to their occurrences.

How to think over oil & gas exploration in thrust belt?Firstly,we should discuss the definiton of thrust belt,thrust fault,overthrust belt,reversed fault and overthrust fault and their differences,and then analyze the causes of formation and mechanisms as well as the tectonic background.

In compress-shear oil and gas bearing basin exploration, early exploration is concentrated on the high position of fault-fold structural zone, many fault-anticline, fault-nose hydrocarbon reservoirs are found, but with the deepening of exploration, the fault trap formed by the reversed fault and convergent torsion fault of these fault-fold structural footwall has to be considered.
