非地震直接油气检测技术及其勘探实践

众所周知,常规地震勘探方法在油气勘探开发中发挥着重要作用。但随着油气勘探开发难度的增加(如复杂山地、前陆冲断带和岩性地层油气藏的勘探与开发等),单一的纵波地震勘探难以满足油气勘探开发的需要。而与油气响应直接相关的非地震油气检测方法的研究和应用,也是降低复杂地区油气勘探风险和综合成本的有效途径。从非地震勘探技术进步和油气藏的物理化学属性特征出发,提出直接油气检测的非地震勘探思路,并通过一些勘探实例探讨直接油气检测的应用前提和条件。以此抛砖引玉,引起广大油气勘探开发科技工作者和各级领导的重新认识和思考。

Non-seismic Technique for Direct Oil-gas Detection and its Exploration Practice

It is well known that general seismic method has been playing an important role in exploration and development of oil and gas. Nevertheless, with the increase of exploration and development difficulties for structural and stratigraphic traps in complex mountainous regions and thrusting belts in forelands and lithologic-stratigraphic oil-gas reservoirs, sole P-wave seismic method barely meets these needs. By contrasting, studies and applications of non-seismic direct oil-gas detection methods show their superiority to reduce the exploration risk and cost. As a result of technical progresses and based on multi-attribute characteristics of oil-gas reservoirs, a non-seismic oil-gas detection strategy is formulated and the application prerequisites of non-seismic methods are studied with exploration cases. So that arouses attentions and reconsiderations from experts and administrators in exploration and development sector of oil and gas industry.
