中文摘要:
      渤海油田近年来相继发现一批古近系油气藏,中深层油田储量规模逐步攀升,成为主力油藏类型,因此中深层储层预测突破对海洋石油工业起到至关重要的作用。但是,渤海中深层油田存在埋藏深、地质沉积条件复杂、地震资料品质差、预测难度大等特点,中深层油田构造破碎、储层展布及流体系统复杂、储量丰度低、油藏类型多样等诸多不利条件,一直是渤海油田地球物理和地质油藏研究的难点,并且对于中深层油田的储层研究和开发,都没有成熟的经验可借鉴。本文针对渤海油田的中深层油田的多期河道叠置特点、不同沉积特征及油藏类型,从叠后地震相入手,实现储层的精细刻画,并逐步解剖复合河道砂体内部的非均质特征,创新形成一套适合中深层油田高效开发的技术体系,并成功应用到渤海其它中深层油田高效开发实践中。
英文摘要:
      In recent years a number of Paleogene oil and gas reservoirs have been found in Bohai Oilfield and the reserve and size of the middle-deep reservoirs increases gradually. Now it is the main reservoir type. Breakthough of middle-deep reservoir prediction plays a crucial role for the Offshore Oil Industry. However, the middle-deep oilfield is characterized by deep burial, complex geological sedimentary conditions, poor quality of seismic data, high prediction dificulty, broken structure, complex reservoir distribution and fluid system, low resvers abundance, variety of reservoir type, that remains the difficulty for grophysical an geological reservoir research. There is no successful experience for the reservoir research and development of middle-deep oilfield. In accordance with multi-stacking and variety of sedimentary characteristics and reservoir types this paper proceeds with post-stack seismic facies and details description of the reservior then interprets heterogenety within the sand body of complex river resulting in innovative high medium-deep oil field sefficient technical system for development of medium-deep oil fields. It has been successfully applied to the other deep oil field in Bohai seaarea.
