济阳坳陷潜山断裂带地震采集设计探讨

济阳坳陷潜山断裂带的隐蔽油气藏模式复杂,勘探难度大;本文从地质角度分析研究了该区复杂潜山断裂带勘探中存在的主要难点。利用正演模拟技术重点研究了济阳坳陷典型的潜山带模式。提出了适用于潜山断裂带油气藏勘探的高精度采集目标设计及全三维地震等方法,并以潜山油气藏勘探为例,探讨了目标采集设计、宽方位采集、以及点激发和点接收等技术及其应用效果。

Seismic Acquisition on the Buried-Hill Faulted Zone of the Jiyang Sag

The pattern of the subtle traps, in which oil and gas accumulated, in the buried-hill faulted zone in the Jiyang sag is very complicated, and very hard to prospect. The paper analyses the main difficulties in exploring the complicated buried-hill faulted zone of the area from a point of geology. The typical pattern of the buried-hill zone in the Jiyang sag is studied using the forward modeling. Target-orient layout design and full 3-D seismic technology, which are useful for oil and gas explo- ration on the zone, are put forward. Taking the exploration for oil and gas traps on the zone as an example, certain technologies and the effect of their applications about the design for target acquisition, acquisition on a wide-azimuth, point sources and point receivers are discussed.
