塔河油田奥陶系碳酸盐岩油藏勘探技术

针对塔河油田古生界碳酸盐岩超深层缝洞型油藏的勘探开发这一世界级的难题，中石化新星石油公司西北石油局近几年来开展了深入，不懈的科技攻关，逐步形成了一套从三维地震成像处理到精细解释，碳酸盐岩储集层预测与评价，油气判别到储集层酸压改造，测试，完井技术以及欠平衡钻井技术，水平井，直井侧钻技术等一套适合于塔河油田古生界碳酸盐岩缝洞型油藏勘探的方法技术系列，取得了很好的效果。这套技术系列对其他地区碳酸盐岩的油气勘探与开发也有着重要的指导和借鉴意义。

The Exploration Technology of Ordovician Car-bonate Reservoir in Tahe Oilfield

The exploration and development of super-deep Paleozoic carbonate reservoir of fissured-cavity that is regarded as difficult problem of world level has been studied by Northwest Petroleum Bureau,CNSPC in recent years.A series of technologies that have been applied to Paleozoic carbonate reservoirs in Tahe oilfield are developed,such as3D seismic imaging processing and detailed interpretation,carbonate reservoir forecasting and evaluation,the oil and gas recognition as well as acid-fracturing,well test and complete,under-balanced drilling,horizontal well drilling,verti-cal well with lateral drilling,etc.The greater advances and notable economic effectiveness are obtained.
