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.
