摘要: 济阳坳陷博兴洼陷历经50多年的勘探开发,发现了纯化、博兴、金家等8个油气田,累计上报探明地质储量超4×108t,目前已进入高勘探程度阶段。回顾博兴洼陷的高效勘探之路,无不体现着科技理论的进步和勘探思路的转变。具体表现在:断坡控砂理论的提出极大提升了下洼找油的信心,实现了由构造油气藏向洼陷带岩性油气藏的转移;咸化湖盆和滨浅湖滩坝的提出坚定了满洼含油的信心,认识到博兴洼陷具有整体含油连片态势;油气分布的有序性、连续性推动了洼陷内多层系、多类型油藏的整体立体勘探,发现了大量源下“红层”油气藏、盆缘地层油气藏,拓展了油气的勘探领域;低油价新形势下,精细化、效益化勘探理念确保今后一段时间内优质、可动用储量的发现。

Abstract: After more than 50 years of exploration and development in the Boxing subsag in the Jiyang depression, eight oil and gas fields such as Purification, Boxing and Jinjia were discovered, and their cumulative proven geological reserves exceed 4×108 tons, but they are all highly explored. In the process of efficient exploration in the Boxing sag, advances of scientific and technological theory and transformation of exploration ideas have been the mainstream. For example, the slope-controlling sandstone theory greatly enhanced the confidence of finding oil in subsags, and realized the transfer from structural reservoirs to lithologic reservoirs in subsag belts; the focus on brackish lake basin and shallow-shore lake beach increased the confidence of subsags full of oil, and revealed that oil in the Boxing subsag should be full and continuous; the order and continuity of oil and gas distribution promoted the overall 3D exploration to multi-layer and multi-type reservoirs in the subsag, and a large number of "red-layer" oil and gas reservoirs and marginal stratigraphic reservoirs have been discovered, expanding the exploration field; at low oil prices, the concept of refined and efficient exploration can ensure the discovery of high-quality and producible reserves in the future.

Key words: efficient exploration, exploration enlightenment, oil-rich sag, Boxing subsag
