西江X-1油田是典型的底水油藏,具有厚底水、薄油层的特点,采用常规水平井开发时,由于流动摩阻和地层非均质性的影响,存在较严重的底水锥进问题,含水率上升过快,开发效果较差。中心管、ICD完井工艺是一种水平井控锥技术,由于其独特的内部结构,能使水平井的供液剖面趋于均衡,从而有效改善底水油藏的水驱效果。为了改善底水油藏的开发效果,对中心管、ICD完井工艺技术进行油藏模拟研究,结果表明,在底水油藏中,中心管、ICD技术的开发效果明显优于常规水平井,单井平均增油2×104~4×104m3。在西江X-1油田范围内进行推广应用,收到了理想的开发效果,实现了底水油藏的成功开发。西江X-1油田的开发实践表明,中心管、ICD完井工艺技术有明显的控锥作用,能有效改善底水油藏的开发效果,也为同类油藏的开发积累了宝贵经验。
The Xijiang X-1 oilfield is a typical bottom water reservoir with the characteristics of thick bottom water and thin oil reservoirs. Due to the influence of flow friction and formation heterogeneity, when using conventional horizontal wells, there is more severe bottom water coning Problems, moisture content rose too fast, the development of less effective. The center tube and ICD completion technology is a horizontal well control cone technology. Due to its unique internal structure, the profile of the horizontal well can be balanced and the water flooding effect of the bottom water reservoir can be effectively improved. In order to improve the development effect of the bottom water reservoir, the reservoir simulation of the central tube and ICD completion technology is conducted. The results show that in the bottom water reservoir, the development of the central tube and ICD technology is obviously better than the conventional horizontal well, The average single well oil 2 × 104 ~ 4 × 104m3. In the Xijiang X-1 oil field to promote the use of the range, received the ideal development results, the realization of the successful development of bottom water reservoirs. The development practice of X-1 oil field in Xijiang River shows that the core pipe and ICD completion technology have a clear cone-controlling effect, which can effectively improve the development effect of bottom water reservoirs and also accumulate valuable experience for the development of similar reservoirs.
