摘要
高升油田高检１井密闭取心证实了蒸汽吞吐采油后，邻井已受到波及，油层的含油饱和度、孔隙度、渗透率等均有明显的降低。受蒸汽吞吐的中、强水洗层，用测井的三电阻率和时差、自然电位对储层的含油性和物性的检测，均有明显的响应特征。高检１井水洗段的含油饱和度虽已降低到４０．９％，但仍有较高的采油指数，与测井检测含油饱和度吻合。用岩心刻度测井，初步建立了水洗级别的解释标准。
Through sealed coring in well Gaojian 1 of Gaosheng oilfield, it was verified that the adjacent wells had been swept after producing by steam stimulation,and the oil saturation, porosity and permeability of the reservoir reduced obviously.The layers flushed by medium and strong water of steam stimulation had got obvious response characteristics when testing oil bearing feature and physical properties of the reservoir with logging methods of three resistivities, time difference and SP.Though the oil saturation of water flushed interval in well Gaojian 1 had dropped to 40 9%,the productivity index was still high, and this oil saturation value was identical with that tested by logging.Interpretation standard of grade of water flushing was set up by core calibration logging.
