【摘要】：近年来华庆地区长9也有多口井试油高产,但是大多数井试油出水,制约了该区勘探的深入。需开展系统的成藏富集规律研究,指导下一步的勘探部署。通过对华庆地区长9基础地质特征研究,分类评价该区储层,在储层评价、成藏富集规律等研究的基础上,优选出建产潜力区。利用研究区的地质标志层建立地层对比模板,通过岩心观察、岩电关系对比,依据标志层,根据沉积旋回,进行精细地层划分与对比,建立起研究区长9等时地层格架。结合宏观构造背景,分析长9小层顶面微构造特征。在区域沉积背景分析的基础上,结合前人研究成果,充分利用岩心地质以及丰富的测井资料,重点研究不同沉积微相及其砂体在纵向和平面上的分布规律的沉积微相特征研究。应用测井资料、岩心分析等资料,通过从微观、宏观不同层次认识储层非均质性特征,分析影响储层物性的主要因素并进行储层综合评价。从成藏要素出发,分析油源、微构造、沉积、砂体展布以及储层特征等与油气富集的关系,在沉积、储层及成藏规律研究基础上,结合勘探生产实践,优选出有利增储和建产区块。华庆地区长9储层发育程度受西北部和西南两大物源控制,根据试油成果,结合地质认识,将研究区划分为7个区域,并在此基础上利用平面区域图版识别法、视电阻增大率法在全区进行油水层识别,并针对各区域建立了油水层识别标准。根据局部区域探评井控制程度,结合已开发区块、未动用潜力区平面分布范围,综合考虑测井解释与储层评价等,共筛选增储4个有利区以深化地质认识、提高区域控制程度,为区域产建提供依据。
[Abstract]:In recent years, Huaqing area has long 9 wells oil yield, but the most well test oil water, restricted the further exploration in this area. To carry out systematic accumulation of research, exploration and deployment guide the next step. The Huaqing area 9 basic geological characteristics, classification and evaluation of reservoir in this area, in the evaluation of reservoir, based on the study of reservoir enrichment, optimized built area. Template layer establishes stratigraphic correlation with geological markers in the study area, through core observation, rock electricity relation comparison, according to the sign layer, according to the sedimentary cycle of fine stratigraphic classification and correlation, establish research Chang 9 isochronous stratigraphic framework. Combining macroscopic tectonic background, analysis of the long 9 small top layer micro structure characteristics. Based on the analysis of the regional sedimentary background, combined with previous research results, make full use of the rich core geology and well logging data, focusing on the different Study on the characteristics of sedimentary microfacies distribution of sedimentary facies and sand body in vertical and horizontal. The application of logging data, core analysis data, through different levels of understanding from the micro, macro heterogeneity of reservoir characteristics, main factors affecting reservoir analysis and comprehensive reservoir evaluation. From the point of accumulation factor analysis of oil source, micro structure, sedimentation, sand body distribution and reservoir characteristics, and hydrocarbon accumulation in sedimentary, reservoir and accumulation on the basis of the research, combined with the practice of exploration and production, optimize favorable increasing storage and built blocks. Huaqing area of Chang 9 reservoir development degree the northwest and southwest of the two major source of control, according to the test results, combined with the geological knowledge, the study area is divided into 7 regions, based on regional plane plate recognition method, apparent resistivity index method are used to identify oil and water in the region, and for the regional construction The oil and water layer identification standard. According to local area exploration appraisal wells control degree, combined with the developed blocks, without potential area of plane distribution use, considering the logging interpretation and reservoir evaluation, there were 4 favorable areas of increasing reserves to deepen geological knowledge, improve regional control degree, regional production provides the basis.
