Abstract: To evaluate the effect of sand prevention in different well completion, a sieve tube evaluation unit about three-dimensional radial flow has been developed according to the sand control conditions of sieve tube. It includes main unit, transporting flow system, liquid stor-age tank,measuring system,sediment filter system, circulating line,collection and control system, etc. The sands were carried to outer sphere of sieve tube by flow transporting system, and one of them went into the sieve tube and entered the sediment filter system, settled in the collecting tank by subside in the end, and the other settled on the outer casing of sieve tube. After pressure drop of sieve tube and distri-bution of powders of formation sands in the sediment tank being analyzed, the effect evaluation would be gained. The units could simulate different mode among perforation, naked well, screen sand control,gravel pack of sand control, and so on, evaluate liquidity, the blocking sand performance, anti jamming performance of different size gravel layer,sorts of sieve tubes.
