摘要
方法 以近 30口各类完钻井的钻井、地质、取心、试油、试采等资料为依据 ,综合应用岩心观察、扫描电镜分析、地球物理测井、地球物理勘探和油田开发动态等方法 ,对胜利草古 1潜山油藏地质特征进行了研究。目的 搞清碳酸盐岩潜山储集空间类型及其分布特征 ;落实潜山油气储量的分布。结果 储集空间以构造裂缝和溶洞为主 ,且具有明显的选择性分布 ;落实潜山石油地质储量 6 38× 1 0 4t,其中约 3/4的储量分布在进山 40m以内。结论 草古 1潜山碳酸盐岩的储集空间及其油气分布 ,主要受构造部位、岩性、地层厚度及埋深等因素影响 ;是一个有效储层厚度较薄、储集空间发育、分布复杂的裂缝、溶洞型特、超稠油油藏。
Method Using drilling, geology, coring, well test, trial production data, and the like information obtained from nearly 30 various completed wells, and implementing core observation,electron microscopy scanning, geophysical logging, geophysical exploration and oil field development performance, we studied the geologic characteristics of Caogu 1 buriedhill reservoir in Shengli oil field. Purpose To understand types of reservoir spaces in carbonate buriedhill reservoirs and their distribution characteristics, also to substantiate distribution of hydrocarbon reserve in same reservoirs. Result Structural fractures and denudation distribute throughout reservoirs and features obviously selected distribution. OIP of this buriedhill is 638×10\+4 t and 3/4 of which distributed within 40 m inward. Conclusion Caogu 1 buridhill carbonate reservoir is an uitrasuper heavy oil reservoir that features complicatedly distributed fractures and denudation and owns relatively thin effective pay zone but reservoir space developed, whose accumulation space and hydrocarbon distribution are subjected to structural location, lithology, formation thickness, buried depth and the like.
