海外河油田防砂技术及其适应性分析

Sand control method of Haiwaihe oilfield and its adaptability

通过对海外河油田主要出砂区块的储层岩性、原油物性、出砂原因的研究,结合各种防砂技术的特点,经过不断地试验和总结,逐步形成了一套比较完整的、适合不同区块的防砂体系,恢复了一批因出砂而停产的油井,提高了油田整体开发水平。

Through study of reservoir lithology, oil property and sand producing reason in major sand producing blocks of Haiwaihe oilfield, combining with features of various sand control techniques, a complete series of sand control system suitable to different blocks has been established after many tests and summarizing. A lot of shut - down wells due to sand producing have been put back on production. and oilfield development is improved.
