【摘要】 中国东部深层油气勘探难度大,但剩余资源量及勘探潜力也大。围绕复杂的勘探对象,近年勘探技术发展动向是欠平衡钻井技术、高分辨率地震勘探技术、成像与核磁测井技术和储层改造技术的联合应用。论述了各项技术的关键,其中两项或多项技术联合应用,实现了松辽盆地深层火山岩油气藏、济阳坳陷深层砂砾岩体油气藏以及东部老油田下部潜山油气藏、煤成气藏勘探的突破。更多还原

【Abstract】 Eastern China deep oil-gas exploration is very difficult, but remaining resources amount and exploration potential are great. Around complex exploration targets, the development trend of exploration technology in recent years is joint application of drilling technology under pressure, high resolution seismic exploration technology, imaging and nuclear magnetism log technology and reservoir renovation technology. The article expounds on key points of each technology, joint application of two or more technologies of them has realized breakthroughs in the exploration of Songliao Basin deep volcanic rock oil-gas reservoir, Jiyang Sag deep arenaceous conglomerate oil-gas reservoir as well as Eastern old oilfields bottom buried hill oil-gas reservoir and coal-seam gas reservoir.更多还原
