准噶尔盆地车莫古隆起浅层成藏因素及勘探方向
|
摘要
为了揭示车莫古隆控制范围内沉积体系和砂体展布控因及对油气成藏的控制,利用岩心、地震、测井等资料,采用多种方法恢复了车莫古隆起的古地貌。提出中侏罗世-早白垩世是车莫古隆起发育期,中侏罗世末是其发育的鼎盛时期,古隆起提供的内物源,控制着围绕车莫古隆起的沉积体系和砂体展布;古隆起的发育和潜伏埋藏期对古油气藏形成起控制作用;两期掀斜调整、内物源砂体展布、断裂体系和现今构造共同控制着油气调整、运移及次生油气藏的分布。围绕车莫古隆起的内物源砂体与现今构造匹配区是岩性地层油气藏发育的有利区,斜坡带是下一步勘探的主攻领域,据此认识部署的莫17井取得突破,围绕车莫古隆起腹部岩性地层油气藏是勘探的新领域。
The several methods are used to recover the paleogeomorphology in Che-Mo paleohigh with the core, seismic and well logging data for revealing the control effect of sedimentary system and sand distribution on hydrocarbon accumulation within this paleohigh. It is suggested that the Middle Jurassic-Early Cretaceous is the period of Che-Mo paleohigh development, and its heyday appears in the late of Middle Jurassic. The inner-sources supplied from this paleohigh control the sedimentary system and sand distribution around it. The development and burial stage of the paleohigh play the roles in control of hydrocarbon accumulation. The oil-gas regulating, migration and secondary reservoirs distribution are controlled by the two-stage tilting regulations, inner-source sand distribution, fault system and present structure. The inner-source sands surrounding Che-Mo paleohigh and the matched area with present structure would be the favorable areas of lithologic-stratigraphic reservoir development, and the slope belt be the focus domain for the next exploration, based on which the breakthrough has been made by Well Mo-17. And the lithologic-stratigraphic reservoirs could be as the new domains around the paleohigh.
