Sleeve type sampling device, relates to the technical field of oil testing oil operations, including the core shaft outer cylinder, inner radial core shaft is fixed on the outer cylinder, two cylinder lug; the core shaft of the outer cylinder in a hollow core shaft, shaft core peripheral radial fixed core the shaft boss, the mandrel convex platform is arranged in the outer cylinder two boss between the upper screw of the mandrel connection joints, threads on the lower end of mandrel connection support ring activity support ring is provided with at least one axial hole; threads on the lower end of the core shaft of the outer cylinder is connected like outdoor drum, like outdoor threads on the lower end connected with the tube joint, joint connecting thread fixed support ring, the fixed support ring is provided with at least one axial hole. The SQ3 sampler placed in the sample outdoor tube has no effect on the entire test channel. The sampler is applied in oil field and solves the difficult problem of taking high pressure physical property sample in thick oil well and high pour point oil gas well.
