【 摘 要 】

For water flooding reservoirs, accurately identify the connectivity of oil and water wells, this is essential for designing a reasonable reservoir development program, it is also the basis for the success of oilfield development and management. Previous studies have focused on the connectivity between oil and water wells, and there is no concrete to the oil and water wells at the simultaneously shot layers. In this paper, numerical simulation technique is used to analyze the connectivity between oil and water wells, and the connectivity relationship of simultaneously shot layers between oil and water wells is also determined. Based on the fine modeling of reservoirs, the connectivity analysis was carried out by using the tracer flow simulation technique in ECLIPSE software and the results of stratified output concentration of tracer in PRT file. The results show, the method can be used to accurately determine the connectivity of oil and water wells. The oil well A in Daqing Oilfield have high water cut layer, using this method, on the 27th floor of well C with the best connectivity of target layer were screened out, the target layer is blocked for wells C, thereby the injecting water is optimized, reduce the amount of inefficient injection of water.
