摘要

摘要: 基于砂岩油藏充注模式,通过研究油藏内部原油成熟度的微细变化,依据成熟度参数的等值线可以示踪油藏充注的过程,成熟度参数等值线向前最为凸出的部位是石油运移/充注的优势途径。通过研究各项饱和烃成熟度参数,筛选出三环萜烷/17α(H)-C₃₀藿烷,Ts/(Ts+Tm),C₃₀重排藿烷/17α(H)-C₃₀藿烷,C₂₉甾烷ββ/(ββ+αα)等4项不受其他地质因素影响的参数,用于王府凹陷扶杨油层原油运移/充注途径的研究。通过17件扶杨油层原油的研究表明,所有参数均反映出王府凹陷原油成熟度分布规律一致,双32井为原油充注点,其离烃源灶最近;研究区内存在3条优势运移/充注途径,一是自双32井往北东方向充注至双26—双301—双31井区;二是自双32井处,经双38井,往北西西方向充注至长64—长11—长17井区;三是自双32井往北西方向充注至双231—双23井区。

Abstract: Based on the filling pattern of sandstone reservoir,according to the minor variation of crude oil maturity in reservoir,the filling pathway has been traced with maturity contour.The peak of maturity contour refers to the advanced pathway for petroleum migration and filling.4 parameters which are not influenced by other geologic factors have been chosen in the studies of petroleum migration and filling pathway in Fuyang oil layer,Wangfu Sag,including tricyclic terpanes/17α(H)-C₃₀ hopanes ratio,Ts/(Ts+Tm) ratio,C₂₉ sterane ββ/(ββ+αα) ratio,and C₃₀ diahopanes/17α(H)-C₃₀ hopanes ratio.17 samples from Fuyang oil layer have been analyzed,indicating that crude oil maturities all over the Wangfu Sag have the same feature.Well Shuang 32 is the filling point which is close to source kitchen.There are 3 advanced migration and filling pathways in the study region: 1)from well Shuang32 to well Shuang26—Shuang301—Shuang31 in NE direction;2)from well Shuang32,crossing well Shuang38,to well Chang64—Chang11—Chang17 in NWW direction;3)from well Shuang32 to well Shuang231—Shuang23 in NW direction.
