针对QHD32-6油田大面积分布的河道砂体中存在单一河道砂体边界这种情况,在全区展开了单一河道砂体的追踪。主要利用研究区有限的测井、测试、取心及示踪剂等资料进行分析研究。根据砂体切割及平面匹配关系对复合砂体进行分类,从而有利于单一河道识别后对复合砂体内部连通关系的认识,为准确地判断油水井的注入或来水方向、剩余油分布等,为油田开发、增产工艺及措施的实施提供更准确的地质依据。
In view of the fact that there is a single channel sandblast boundary in the large-scale distribution of channel sand in QHD32-6 oilfield, tracking of single channel sandbodies has been carried out in the whole region. The main use of the study area limited logging, testing, coring and tracer and other data analysis and research. According to the relation between sand body cutting and plane matching, the composite sand bodies are classified, which is benefit to the understanding of the internal connectivity of composite sand bodies after single channel identification. In order to accurately judge the direction of injection or incoming water and the remaining oil distribution, It will provide a more accurate geological basis for the implementation of oilfield development, stimulation technology and measures.
