火成岩遮挡油藏特征及滚动勘探开发实践
|
摘要
火成岩在东部第三系地层中较为发育 ,对应的火成岩油藏具有“小而肥”的特征 ,已成为目前老区滚动勘探与开发挖潜的一种重要类型 ,尤其是火成岩遮挡类型油藏 ,但由于其空间分布与成藏特征的复杂性决定了经济高效的滚动勘探开发技术是其成功的关键。以火成岩遮挡油藏模型及其对应的地震T0 模型与地震解释模型的建立为基础 ,研究总结了火成岩遮挡类油藏的典型特征。在此研究的基础上 ,应用于高 81块火成岩遮挡油藏的勘探与开发 ,取得了初期的勘探、1998年的滚动开发、2 0 0 0年的油藏精细描述有突破 ,实现了该块原油生产能力的提高。高 81块的勘探与开发程序及研究方法对东部老油区、尤其是“小而肥”的火成岩遮挡类型油藏的进一步提高滚动勘探开发水平具有现实的参考作用
Igneous rock distribute widely in Tertiary in the east of China and the igneous rock reservoirs have"small and rich"features which is important reservoir for extended exploration and development in old areas to seek potential reserves and enhance efficiency,especially,igneous rock screened reservoir.But because of the complexity of space distribution and forming features,high efficiency techniques are key to achieve task during extended exploration and development.The typical features of igneous rock screened reservoir are studied and concluded in this paper on the basis of seismic T 0 model and seismic interpretation model.In the practice of extended exploration and development of Gao 81 block igneous rock screened reservoir, auther made new discovery in the early,new progress of extended exploration in 1998 and a breakthrough of fine study in 2000,and production capacity of this block incerased significantly.Evidently,the process and study method of the exploration and development of Gao 81 are practical and typical for the farther exploration of eastern old area,expecially the progress of extended exploration and development of "small and rich" igneous rock screened reservoirs.
