Conventional coring tool with the following characteristics: 1, outside the tube thick-walled seamless steel pipe for high intensity of production, and with a number of stabilizer, high intensity, good stability, conducive to improving the core harvest rates, to extend the service life of diamond coring bit. 2, with the exception of steel tube, but also equipped with light, temperature, corrosion resistance, high strength, smooth wall, etc. within the glass tube steel, into the resistance of small cores. Help to improve the soft, broken harvest rate of core formation. 3, each inner and outer tube equal in length (9.2m), the operator can be chosen at random to form the core tube of different lengths. Within the outer cylinder tube set up in hanging together, you can save lot of assembly time. 4, the stabilizer helix coring surface mount solder alloy, and grinding smooth surface without pores, good wear resistance, less torque. 5, when the core barrel was stuck in the underground, it is easy connection from the security thread Office was open from the inside the tube and core, leaving only the outer tube to salvage. 6, the design of the structure of five kinds of different forms of core claws can choose according to different strata. 7, a full range of aids to make it easier coring operations, more support can save hours of work, especially for the high cost of drilling in areas (such as the ocean) the effect of the coring operation more remarkable.
