【摘要】：渤海油田经历了以凸起潜山为主的摸索阶段、以古近系为主的勘探阶段、以新近系为主的勘探阶段和多层系立体勘探阶段,目前已全面进入精细勘探阶段。提出了精细勘探背景下渤海油田成熟区勘探新思路,即以差异成藏分析指导重点靶区优选和勘探层系调整,以一体化勘探带动油田周边拓展和油田内部挖潜,以新理论新技术保证勘探空间拓展和钻探成功率。在此基础上,开展了成藏关键要素的精细研究,主要体现在4个方面:1精细生烃单元研究,重视盆缘凹陷的特殊性和富烃凹陷的差异性;2精细沉积与储层研究,重视在差储层背景中寻找优质储层;3精细构造解释,重视隐性走滑断层的作用;4精细复杂断块成藏研究,优先寻找油气富集块。精细勘探背景下勘探新思路的提出,指导勘探取得了新进展,成功发现了渤中34-9、曹妃甸12-6等一系列复杂油气田及一批勘探目标,保证了渤海油田储量发现保持稳定持续增长。
[Abstract]:Bohai Oilfield has experienced the exploration stage of uplift buried hill, Paleogene exploration, Neogene exploration and multi-layer stereoscopic exploration. At present, it has entered the fine exploration stage in an all-round way. This paper puts forward a new idea of exploration in mature area of Bohai Oilfield under the background of fine exploration, that is, using differential reservoir forming analysis to guide the optimization of key target areas and adjustment of exploration layers, and to promote the peripheral development of the oilfield and the tapping of potential inside the oil field by integrated exploration. New theory and technology are used to guarantee exploration space expansion and drilling success rate. On this basis, the fine research on the key elements of reservoir formation is carried out, which is mainly reflected in the study of 4 aspects of fine hydrocarbon generation unit, the particularity of basin margin sag and the difference of hydrocarbon rich sag and the study of fine sedimentation and reservoir. Attention should be paid to the exploration of fine structural interpretation of high quality reservoirs in the background of poor reservoirs, the role of hidden strike slip faults in the reservoir formation of complex fault blocks and the preferentially searching for oil and gas enrichment blocks. Under the background of fine exploration, a series of complex oil and gas fields such as Bozhong 34-9, Caofeidian 12-6 and a number of exploration targets have been successfully discovered, which ensures that the discovery of reserves in Bohai Oilfield keeps steady and continuous growth.
