Product Details


Male cone belongs to a kind of oil salvage tools. Male cone is a kind of tool specializing in making buckle salvage from the inner hole of oil pipe, drilling pipe, casing milling pipe, packer, water distributor, production distributor, etc., which have holes to fall objects.

Use

The male cone has a high success rate in salvaging the falling objects of pipes with connecting hoops. The male cone can be used with positive and negative buckling drill rods and other tools to realize different salvage processes.

Structure

The cone is a long conical structure, which can be divided into two parts: the joint and the salvage thread. The upper part of the connector has threads connected with the drill pipe to connect the pilot shoe. The cone has water eyes from top to bottom. The most important part of the male cone is the salvage thread, and there are two different specifications according to the cusp angle classification.

①Thread tooth tip angle of 55 °, pitch of 8 buckle / in. This salvage thread is used more, the advantage is that the thread tooth tip angle is smaller, easy to eat into the inner wall of the falling fish, the required torque to make buckle is also smaller. But because of the tip angle is small, tooth root section is also correspondingly small, thread strength is low, not suitable for salvage material is hard, toughness of the fallout, such as P110 material of the fallout, in the buckle may cause thread collapse extrusion, salvage part of the thread damage, resulting in salvage failure.

The advantage of this kind of salvage thread is that the tip angle is increased, the pitch is increased, and the cross sectional area of the root of the thread is relatively increased, which improves the strength of the salvage thread, and it can withstand the larger buckling torque and pulling load, but due to the increased tip angle, the buckling torque is larger when the buckling depth is the same as that of the 55°tip angle, thus increasing the ground buckling torque. However, due to the increase of the tip angle, the buckling torque at the same depth as the tip angle of 55° increases, thus increasing the ground buckling torque. This kind of salvage thread, for the material is harder, toughness is bigger falling objects, salvage success rate is higher.

Working principle

After the male cone enters the inner hole of the salvaged fallen object, add appropriate drilling pressure and rotate the drilling tool, forcing the salvage thread to squeeze and eat into the inner wall of the fallen fish to make buckles. When the buckle can withstand a certain amount of tension and torque, it can be lifted up or inverted to salvage all or part of the fallen objects. The old male cone with a number of chip slots, the original design intent of this slot is to discharge the iron filings generated by the buckle cutting, while the actual buckle-making conditions are extrusion molding, and no iron filings generated. Practice has proved that the chip removal slot does not work, and for some of the buckles need to hold pressure after the operation is extremely unfavorable, because it can only withstand 10MPa below the pump pressure, and then higher, it will be strung from this slot.
