辽东湾坳陷挤压型和拉张型走滑转换带特征及其控藏作用
CHARACTERISTICS OF THE COMPRESSIONAL AND EXTENSIONAL STRIKE-SLIP TRANSFORM BELTS AND THEIR CONTROLLING ACTIONS ON THE HYDROCARBON ACCUMULATION FOR LIAODONG BAY DEPRESSION
摘要
Abstract
Strike-slip transform belts possess obvious controlling actions on the hydrocarbon accumulation,the developed belts in Liaodong Bay Depression control the accumulation of the large and medium oil and gas reservoirs.With the help of the fine structural interpretations of 3D seismic data and integrated with the drilled achievements,the belts were subdivided into right lateral-left step-compressional strike-slip transform belt and right lateral-right step-extensional strike-slip transform belt,and moreover the controlling effects on the hydrocarbon accumulation of the two kinds of the belts were clarified.The researches show that the former belt can form a large amount of the anticline traps,which have the well-preserved conditions and deeper reservoir accumulation;while the later is characterized by the much better hydrocarbon migration conditions and shallower accumulation,and furthermore can be subdivided into extensional-torsional transforming zone,extension adjusting zone and single strike-slip-fault controlling zone.The former and latter are prone to form anticline and semi-anticline traps;while the middle is easy to generate fault block traps.关键词
