英台油田英东萨尔图精细油藏描述
|
摘要
本论文针对英台油田英东萨尔图油藏采出程度低、剩余油分布不清、注采关系混乱,平面、层间矛盾突出、地层压力低等问题,应用地质、地震、测井、测试等资料,以沉积岩石学和储层地质学理论为指导,通过地层精细划分与对比,采用了在标准层控制下“旋回对比,分级控制”的对比方法,将该区的萨尔图油层划分为三个砂组,9个小层;通过对区域沉积背景、相标志、储层岩石组份、沉积层理和构造、沉积序列等方面研究,并结合区域资料分析、研究沉积微相的分布和时空展布,确定储层沉积类型,即萨尔图油层为三角洲前缘沉积,主要发育辫状河三角洲和浊积扇两种相类型;用密井网测井资料,通过寻找沉积间断面方法划分单砂体,并对沉积间断面的测井特征、单砂体三维空间展布以及单砂体间的连通关系进行研究明确单砂体三维空间展布及单砂体间的连通关系;根据构造、沉积、储层等研究成果,对研究区建立储层砂体三维地质模型,为储层非均质性的研究和有利区块的预测打好基础;以小层为单元,用岩芯分析物性、含油性资料,结合试油、投产及生产动态结果,建立新的解释模型,对原有测井综合解释结论进行修正,在此基础上复核地质储量,为客观评价开发效果提供依据;在对英台油田萨尔图油藏静态特征深入研究此基础上,进一步对剩余油主控因素及分布规律进行了分析,并预测英台萨尔图油层的剩余油分布有利区。
通过油藏精细描述,英台英东萨尔图油田的沉积微相、储层单砂体分布、剩余油分布规律形成了一个清晰的认识,为下一步井网加密部署、注水方案调整以及区块最后挖潜对策研究提供依据。
Based on Logging data(including data of Production Logging and test), taking Modern sedimentology, geology and reservoir engineering Logging as instruction, fine reservoir description can take advantage of a wealth of dynamic and static information to subdivide and correlate the oil sand body, make a description of reservoir sedimentary microfacies and Micro-reservoir structure, construct reservoir geological model, describe the distribution of oil, gas and water, through the consider of sequence stratigraphy analysis combined with the analysis of logging curve, dynamic data of field and movement trace of water and oil. Then, block of the potential distribution can be determined; the Reserves can be calculated, the relevant adjusting step can be promoted.
According to the problem of geological work and reservoir understanding surviving in exploitation process of Saertu Yingdong, such as, unclearness of reservoir control factors and reservoir types, unclearness of reservoir structure especially the development and distribution of micro-structure, further study needed of the development and distribution of sand body as well as its control effect to reservoir, great discrepancy between water driving control reserves and water driving employ reserves, extruding plant conflict, distribution of water going up quickly, making exploiting difficult. This program's main purpose is to solve conflict of dynamic and static exploitation as much as possible, make it clear that the effect of the impact of oil field development of the basic geological features.
As the program processing, we can make the oil distribution and oil field development rule clear, accordingly, we can make sure which place to dig hole and provide the basis for increasing reserves. By so, reservoir recovery can be promoted, nature degression can be decreased, exploitation of reservoir can be more improved. There is not only important practice significance for the stability of Yingtai oil field, but also important direction significance for reasonable exploitation of reservoir of the same type.
