The invention provides a fracturing and sand prevention pipe column and a fracturing and sand prevention method. The fracturing and sand prevention pipe column comprises a casing pipe and an oil pipearranged in the casing pipe, an annular space is formed between the casing pipe and the oil pipe, a fracturing packer is arranged on the oil pipe, a ball seat and a sand prevention sieve pipe are arranged in the bottom end of the oil pipe in a sleeved mode, the ball seat is in threaded connection with the upper part of the sand prevention sieve pipe, the bottom end of the oil pipe is connected with a limiting device, the limiting device is located on the lower part of the sand prevention sieve pipe, and the length of the sand prevention sieve pipe is greater than the thickness of a reservoir by 20 to 30 meters; a female buckle is arranged at the top end of the sand prevention sieve pipe, and a limiting groove is formed in the limiting device; when a soluble ball is put to strike the ball seat, the ball seat drives the sand prevention sieve pipe to move downwards until the female buckle is clamped in the limiting groove; and after the sand prevention sieve pipe is in place, still standing is conducted for 48 hours, and the soluble ball is dissolved. According to the fracturing and sand prevention pipe column, under the situation of not conducting secondary well completion, it can beensured that stratum sand and fracturing sand do not flow back from a stratum, and fracturing and sand prevention is integrated.
