渤海湾盆地物探技术需求及发展方向

Geophysical prospecting requirements and development direction in Bohai Bay Basin.

渤海湾盆地是我国油气勘探开发的重要基地,随着勘探程度不断深化,油气勘探开发对象向复杂潜山、岩性油气藏、深层非常规油气藏等复杂领域延伸,从而对地震技术提出了刻画更小目标、识别特殊岩性体和致密储层、刻画深层目标的要求,物探技术面临精细描述复杂储层、提高深层目标落实精度、提高油藏建模精度、提高低丰度油气识别精度等四方面挑战。需要发展面向地质目标的地震采集、面向复杂储层预测的目标处理及面向油藏描述的综合解释技术,为渤海湾盆地油气勘探开发提供有力技术支撑。

Bohai Bay Basin is a very important oil and gas exploration base in China.Along with prospecting progress,the oil and gas exploration and production objects extent to complex buried hill,stratigraphical hydrocarbon reservoir,igneous rock,and deep unconventional reservoirs.New geophysical technologies are needed to describe small target,identify special lithology and tight reservoir,and characterize deep object.At present,4main challenges for geophysics are:complex reservoir char-acterization,deep object confirmation,reservoir modeling improvement and low abundance reservoir identification.New approaches such as targetoriented seismic acquisition,object-oriented processing,and reservoir-oriented interpretation are badly needed to support oil and gas exploration & production in Bohai Bay Basin in the future.
