全数字地震叠前储层预测技术在苏里格天然气勘探中的研究与应用
|
摘要
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。
The Sulige area is an important area of natural gas exploration and development with complex surface conditions and lateral variable continental sedimentary reservoirs. In recent years, in view of the complex geological conditions and the Paleozoic gas exploration, the higher-coverage acquisition techniques with long array, small interval and single digital receiver were formed through the seismic exploration study of the all-digital seismic acquisition, processing and interpretation. The seismic pre-stack processing techniques, pre-stack inversion and post-stack interpretation methods have been gotten many achievements. All above could meet the needs of seismic pre-stack effective reservoir prediction and help the rapid and efficient exploration and development in the Sulige area.
