Description
Technical field
The invention belongs to technical field of petroleum extraction, and in particular to a kind of oil exploitation cylinder sleeve and preparation method thereof.
Background technology
The cylinder sleeve of mud pump for petroleum drilling is key components and parts, and one end of cylinder sleeve and slush pump fluid cylinder general assembly are one
Rise, piston is connected to by the piston rod of power end high pressure axially reciprocating realization is carried out inside cylinder sleeve to drilling mud
Suction and discharge.Traditional cylinder sleeve is main to be made up of insert inner cylinder sleeve together and cylinder overcoat, as shown in figure 1, inner cylinder sleeve a and cylinder
Overcoat b axial length is consistent, in the assembled condition, and inner cylinder sleeve a both ends of the surface keep neat with cylinder overcoat b both ends of the surface
It is flat.Using the cylinder sleeve of this structure, easily it is in contact at installation process middle cylinder set assembling end with counterpart or other rigid objects
And cause inner cylinder sleeve to be collided with, while also exist causes because the hot insert magnitude of interference of cylinder sleeve inner-outer sleeve is low or inner-outer sleeve contact surface is small
The danger that inner sleeve is press-offed, operational efficiency and personal security for equipment cause very big hidden danger.
In recent years, the drilling well under the complex geological conditions such as deep-well, hard formation, drilling at the sea, the high pump pressure widelyd popularize and
Jet drilling technology under the conditions of huge discharge proposes higher to the wearability, corrosion resistance and the fatigue resistance that creep into pump liner
It is required that, traditional cylinder sleeve can not meet use requirement, and initial failure easily occurs for cylinder sleeve, cause drilling cost to remain high, resistance to
Mill property, corrosion resistance and fatigue resistance deficiency are main causes, meanwhile, cylinder sleeve quality is not uniform enough, there is space in material,
Also it have impact on its intensity.
