    摘要:

    为了控制低温油井出砂和提高油井产量,采用覆膜砂人工井壁化学防砂是一种有效期长、施工简单的防砂措施。由于目前常用的覆膜砂在低温(低于50℃)或水环境中不发生固结反应,因此需要研制同时满足低温和水环境下能固结的覆膜砂固结体系。本文研制出以改性环氧树脂为制作覆膜砂的胶结剂、新型水溶性胺类为固化剂的低温固结体系,在25~50℃和水环境下形成的固结体具有高的抗压强度、渗透率和良好的耐冲刷性能,满足低温油井人工井壁防砂要求。低温出砂油井采用改性环氧树脂覆膜砂人工井壁防砂技术后,出砂量得到了抑制,单井日产量超出酚醛树脂覆膜砂固结体系的一倍以上,且有效期要延长1年以上。

    Abstract:

    In order to control sand production and improve productivity of low temperature oil well, using coated sand artificial borehole wall technology is a long valid time and simple construction measure. Because of non-condensable of common use coated sand in low temperature (lower than 50 degree centigrade) and water environment, so it is necessary to develop a coated sand system which can be solidified in these two condition simultaneously. This paper developed low temperature consolidation system which uses modified epoxide resin as cementing agent of coated sand and new type of water-soluble amine as solidified agent. In 25-50 degree centigrade and water environment, the formative consolidation has the ability of high compressive strength, high permeability and strong swashing resistance, satisfied the request of low temperature oil well artificial borehole wall sand control. Using this technology in low temperature and water environment, sand production volume had been suppressed, production of single well was more than twice as much as the phenolic resin coated sand consolidation system, and the period of validity can extend more than one year.
