摘要
文留油气田属于复杂岩性构造油气田,目前已进入滚动勘探开发阶段.对其地质特征进行系统研究,总结出滚动增储模式:主要为构造及工区结合部、老区扩边、老区新层、与盐岩有关的各种隐蔽油气藏等6种类型.并有针对性地采用沉积微相、储层发育规律、油气富集规律、地震资料特殊处理、动静态分析法、低阻油层形成机理与识别等滚动勘探开发研究,取得了较好的效果,每年新增石油地质储量400×104～600×104t.
Wenliu oilfield is a complex lithologic-structural oilfield and has entered progressive exploration and development stage. This paper studies the geologic characteristics and the methods of progressively increasing reserves: mainly including 6 types, such as combination of structure and work area, oil zone extension, new layers in old zones, and various subtle reservoirs related to salt rock, etc. Progressive exploration and development studies like sedimentary micro facies, reservoir development law, oil and gas accumulation law, special processing of seismic data, dynamic and static analysis, and low resistivity reservoir forming mechanism and identification are conducted accordingly. Good result has been achieved, with annual OOIP increment of 400×10~4～600×10~4t.
