苏里格地区是天然气勘探开发的重点地区。该区近地表结构复杂,储层为陆相沉积,横向变化大。近几年来,针对该区复杂的地震地质条件和上古生界天然气勘探目标,开展了以全数字地震采集、处理、解释为代表的地震勘探技术攻关,形成了以长排列、小道距、单点数字检波器接收的高次覆盖采集技术;以保持叠前动力学特征为核心的叠前地震资料处理技术;以叠前反演与叠后综合解释相结合的储层预测技术系列,取得了丰硕的地震地质成果,满足了叠前有效储层预测需要,为苏里格地区快速、高效勘探开发提供了有力技术保障。
Sulige area is the focus of natural gas exploration and development. The area near the surface of the complex structure, the continental shelf sediment, lateral changes. In recent years, in view of the complicated seismic geological conditions and the exploration targets of the Upper Paleozoic in the area, seismic exploration technology represented by all-digital seismic acquisition, processing and interpretation has been developed. A long-range, small-track, High-frequency coverage acquisition technology by digital geophone; pre-stack seismic data processing technology with prestack dynamic characteristics as the core; and reservoir prediction technology combining prestack inversion and post-stack comprehensive interpretation, and achieved great results Of the seismic geological results, to meet the pre-stack effective reservoir prediction needs for the Sulige area for rapid and efficient exploration and development provides a powerful technical support.
