辽河高升油田北部沙4段重力流沉积特征及其分散体系
|
摘要
根据辽河西部凹陷高升油田北部地区重力流特征的岩心资料、递变悬浮的粒度特征,结合测井和地震等资料所反映出的重力流特点,认为该区主要发育重力流沉积。根据地震属性揭示的沙四段时期砂体与同生断层的展布情况,结合研究区东倾的斜坡古地形,揭示了研究区沉积物的分散体系,认为其物源主要来自于西北部。重新厘定的沉积相类型和沉积物分散体系,将促进该区的岩性油气藏勘探。
On the basis of the core data of gravity current characteristics and the grain-sizes distribution of change suspension in northern Gaosheng oil field of western Liaohe depression,the authors considered that the studied area mainly developed in gravity flow deposit combined with the gravity current characteristics reflected by well logging and seismic data.According to the distribution of sand body of the 4th Member of Shahejie Formation and its contemporaneous faults showed by seismic attribute,the authors revealed the dispersion system,which indicated that the sediment sources maily came from northwest combined with the east-leaned slope paleotopography eastward tilted in the studied area.The new determined sediment face types and dispersion system will promote the exploration of lithological reservoir in the studied area.
