The invention relates to an oil deposit purification sewage sand-carrying filling sand prevention method and a sand prevention pipe column. The method comprises the following steps of 1, putting the sand prevention pipe column provided with a top packer in a predetermined position in a well, conducting packing, and opening a filling sand adding channel; 2, with oil deposit purification sewage withthe viscosity of 1.4-1.6 mPa.s as sand-carrying liquid, mixing the oil deposit purification sewage with quartz sand with the particle size of 0.4-0.8 mm according to the sand-carrying ratio of 3-15%,and afterwards, conducting positive squeezing and filling; 3, conducting releasing, and backwashing remaining sand in a pipe. According to the method, the oil deposit purification sewage with low viscosity serves as the sand-carrying liquid, the risks of sand blocking and sand burying are reduced, successful sand adding is ensured, and the construction requirement for low-sand-ration filling sandprevention is met. The sand-carrying liquid is the purified thickened oil sewage of an area where a construction well is located, has good compatibility with stratum liquid and stratum minerals, avoids the situation that chemical reactions are caused and sediments clog stratum pores, and is wide in source, cheap and low in cost.
