塔里木盆地中石化探区油气勘探进展、难点及技术需求

回顾了中石化在塔里木盆地油气勘探的历程, 总结了经验、教训, 明确了中石化在塔里木盆地取得的三大油气勘探成果。梳理了塔里木盆地不同探区、不同类型油气藏勘探难点, 总结了主要物探技术进展及应用成果。油气勘探实践结果表明, 大油气田的发现离不开勘探理论创新和技术进步, 特别是三维高精度地震勘探技术。面对更深、更小、隐蔽性更强的勘探目标, 提出了需要夯实地震波场发育机理基础研究, 发展超深层低信噪比区高精度地震采集技术, 攻关低序级断裂、小尺度缝洞目标处理技术及山前复杂速度场条件下构造成像技术, 探索人工智能技术、叠前叠后联合应用技术在强非均质性碳酸盐岩缝洞储层预测及油气检测中的应用研究。

This study reviewed the history of petroleum and gas exploration in the Sinopec region in the Tarim Basin, summarized the experience and lessons, and identified three significant petroleum and gas exploration achievements.We also outlined the exploration difficulties of different exploration areas and different types of oil and gas reservoirs in the Tarim Basin and the progress and application results of major geophysical exploration techniques.The practice of oil and gas exploration has shown that discovering large oil and gas fields is inseparable from theoretical innovations and technological progress, especially three-dimensional high-precision seismic exploration technology.In the face of deeper, smaller, and more concealed geological exploration targets, we proposed to consolidate the research foundation of the development mechanism of seismic wave fields, develop high-precision seismic acquisition technology in ultra-deep and low signal-to-noise ratio areas, address the processing technology of low-sequence faults and small-scale fracture-cavity targets, and ascertain the technology of the structure under the condition of a complex velocity field in a foremountain.Artificial intelligence technology and pre-stack and post-stack combined application technology were applied in the prediction and hydrocarbon detection of highly heterogeneous carbonate fracture-cavity reservoirs.
