本文在分析相关资料后认为相邻生油凹陷生成的原油通过网毯式输导体系运移到本区,与本区良好的区域盖层、储集条件、多种圈闭条件及较弱构造改造作用,有利于油气藏的形成与保存。为提高勘探效果,文中提出了在勘探目标择上应在立足新近系“滩坝”岩性圈闭的同时向古近系、侏罗系、白垩系、石炭系不整合地层圈闭、断块圈闭、古潜山及内幕圈闭、复合圈闭方向拓展,在技术上应完善全三维地震资料采集、高保真保幅处理、立足“亮点”走出“亮点”识别含油圈闭等地震采集处理解释技术,完善弱显示、特殊气测组分、低阻油层识别与评价技术、高渗砂岩油层保护技术、深稠油层试采技术等石油工程技术。
In this paper, after analyzing the relevant data, it is considered that the crude oil generated by the adjacent oil-producing depression migrates to this area through the networked transmission system and is in good contact with the caprock, reservoir conditions, various trap conditions and weaker structure Transformation, is conducive to the formation and preservation of oil and gas reservoirs. In order to improve the exploration results, the paper proposes that the exploration target should be based on the tracing of the Neogene “beach dam” lithology traps to the traps of the Paleogene, Jurassic, Cretaceous and Carboniferous unconformities, Fault block traps, buried hills and traps, the expansion of composite traps, the technical should improve the full three-dimensional seismic data acquisition, high-fidelity preservation processing, based on “bright spot” out of “bright spot” to identify the oil ring And other seismic acquisition and processing technology to explain and improve the weak show that the special gas components, low resistance reservoir identification and evaluation techniques, high permeability sandstone reservoir protection technology, deep heavy oil exploration technology, and other petroleum engineering.
