华北探区潜山勘探地震采集技术进展
|
摘要
为了进一步提高华北探区冀中坳陷潜山勘探开发油气资源,近年开展了针对潜山复杂地表、复杂地下地震地质条件的技术攻关。本文对以往华北探区冀中坳陷潜山勘探进行了地震历程回顾和采集技术系统总结,在此基础上提出了下步勘探方向。以上研究分析表明:(1)冀中坳陷潜山地震勘探经历了二维普查—三维普查—精细详查—目标勘探等阶段,不同勘探阶段形成的地震采集技术满足了当时潜山勘探的地质需求,随着地质认识的深化和勘探需求的精细化,地震采集技术需要与时俱进;(2)目前成熟的潜山地震勘探配套技术有效解决了常规潜山内幕资料差的问题,但在隐蔽型潜山或深潜山及内幕方面还有待提升;(3)冀中坳陷隐蔽型深潜山及内幕勘探技术展望——以深度、介质特性、资料特征为切入点,开展岩性、速度建模等专题研究,形成针对目标的观测系统设计方法,以及形成适应复杂地表条件的安全、绿色、高效配套采集技术。以上研究可以为潜山精细勘探提供参考价值。
In order to further improve the exploration and development of oil and gas resources in the buried hills of Jizhong Depression, technical research on complex surface and underground seismic geological conditions of buried hills has been carried out in recent years. In this paper, the seismic history of buried hill exploration in Jizhong Depression is reviewed and the acquisition technology is systematically summarized. On this basis, the next exploration direction is put forward. The above research and analysis show that:(1) seismic exploration in buried hills of Jizhong Depression has gone through 2 D, 3 D, fine detailed survey, target exploration stages. Seismic acquisition technology formed in different exploration stages met the geological needs of buried hill exploration at that time. With the deepening of geological knowledge and the refinement of exploration requirements, seismic acquisition technologies need to keep pace with the times;(2) Currently mature matching techniques for seismic exploration in buried hills have effectively solved the problem of poor information in conventional buried hills, but still need to be improved in terms of concealed buried hills or deep buried hills and inside;(3) Prospects for concealed buried hills and inside exploration techniques in Jizhong Depression—Depth, medium characteristics and data characteristics as the starting point, special research on lithology and velocity modeling is carried out, and the design method of target-oriented observation system is formed, as well as the safety, green and efficient matching acquisition technology adapted to complex surface conditions. The above research can provide reference value for fine exploration in buried hill.
