Zirconia Sleeved Liners for Mud Pumps in Drilling Applications Basic description of Zirconium Oxide/Zirconia: Zirconia engineered ceramic parts can be formed by single axis pressing, isostatic pressing, injection molding, slip casting, or extrusion. Parts can "green machined" to near net size before firing and then "hard" ground using diamond tooling to tolerances less than 0.0002" (0.005 mm). Special grades of zirconia can be enhanced with additives to create a multiphase material and also metallized creating an option to be brazed to metal parts. Applications: Although there are a number of uses for Zirconia, the application of a Zirconia sleeve for a mud pump liner is gaining increasing attention. Although other materials have been used for mud pump liners such as high chromed sleeves and Aluminum Oxide sleeves, Zirconia is gaining favor in this application. A Zirconia sleeve is much harder than a chrome sleeve and therefore offers longer life. Although Ziconia is softer than Alumina, it is not as brittle and therefore will survive low impact shock loading and moderately rough handling. The run life of these two ceramic materials is very close, however because of the careful handling required by Alumina sleeved liners to prevent cracking damage, Zirconia liners are preferred. The Multiphase compound process results in a much smaller grain size which is one of the factors to improve wear life.

When a liner reaches about .070" over nominal diameter the engagement with the piston reduces to a point that blow by begins, resulting in piston failure. The liner wears like a barrel on the ID resulting in the maximum wear at the center of the stroke. The ends of the liner will be at the original nominal diameter. Ceramic sleeve liner will wear in the same way as chrome liners but at a rate of about .001" or less per 100 hours. This rate of wear will result in potential life of 10,000 or more hours. Of course there are a number of variables which would shorten or even lengthen the run time. Recent tests conducted with KCA Duetag and Nabors Drilling have confirmed that wear of only .020 or less have occurred in 4000 hours. Projection of this wear rate would indicate a life of 14,000 hours or more. Urethane pistons are recommended for use with ceramic liners. Piston life in a ceramic liner is variable. The initial piston normally will only run about 200 hours or less. During the initial run the piston further smoothes the liner ID. Subsequent pistons have been known to run much longer up to 500 or 600 hours. However, as the liner becomes worn, the piston lip will begin to loose interference with the liner ID, reducing run life. The above noted run times are dependent on operating conditions. Typical conditions are pressure to 3800 psi, stroke rate to 90 spm, temperature below 170 degrees F, clean mud with weights of 11 to 14 lbs. and a high volume water flush to the back of the piston is required. Higher pressures, stroke rates and temperatures will increase the wear rate.

TECHNICAL FIELD OF THE INVENTION The present invention relates generally to piston seals for mud pumps and more particularly to a replaceable piston seal. Still more particularly, the present invention relates to a durable polymeric piston seal constructed with very small tolerances so as to provide a precise interference fit with the corresponding liner.

Slush or mud pumps are commonly used for pumping drilling mud in connection with oil well drilling operations. Because of the need to pump the drilling mud through several thousand feet of drill pipe, such pumps typically operate at high pressures. Moreover, it is necessary for the mud to emerge from the drill bit downhole at a relatively high velocity in order to provide lubrication and cooling to the bit and to provide a vehicle for the removal of drill cuttings from the earth formation being drilled. Lastly, the pressure generated by the mud pump contributes to the total downhole pressure, which is used to prevent well blowouts.

The pistons and cylinders used for such mud pumps are susceptible to a high degree of wear during use because the drilling mud is relatively dense and has a high proportion of suspended abrasive solids. As the pump cylinder becomes worn, the small annular space between the piston and the cylinder wall increases substantially and sometimes irregularly. For these reasons, the seal design for such pumps is critical.

The high pressure abrasive environment in which the pumps must operate is especially deleterious to the seals since considerable friction forces are generated, and since the hydraulic pressures encountered during operation force the seal into the annular space between the cylinder wall and the piston. In some instances, the frictional forces may even detach the seal from the piston. In these instances, the edges of the seal can become damaged very quickly by the cutting or tearing action that occurs as a result of piston movement. Another problem with conventional mud pump seals is that they do not adequately "wipe" the

It is common to incorporate the foregoing seals into piston heads wherein the seal is permanently affixed to the piston head. This is disadvantageous because the seal tends to wear much faster than the piston head, resulting in waste and unnecessary expense when the whole piston head has to be replaced because of wear to the seal member. It is therefore desirable to provide a piston seal that is removable from the piston head and thus can be replaced without requiring replacement of the whole piston head. The nature of the mud pump operating environment makes it difficult to effectively address these issues. It is, therefore, desired to develop a new and improved replaceable seal for a reciprocating mud pump piston that overcomes the foregoing difficulties while providing better wear properties and more advantageous overall results.

BRIEF SUMMARY OF THE INVENTION The present invention comprises a new and improved replaceable seal for a reciprocating mud pump piston. The present seal does not require any external seal retaining means and is free from any incorporated seal retainer or reinforcement. The present seal is manufactured to precise specifications that minimize play between the seal, piston head and cylinder and also compensate for the slight deformation of the seal member that occurs when the seal member is demolded and cured.

Referring initially to Figure 1, a typical prior-art mud pump piston assembly comprises a piston head 10 and a sealing device or seal 15 therefor slidably received in a piston cylinder 12. Piston head 10 comprises a generally cylindrical body having a flange 11 extending therefrom. Piston head 10 is typically made of steel, such as AISI 4140. Seal 15 is friction fit on piston head 10 and abuts flange 11. Seal 15 comprises an elastomeric sealing section 14 and a heel section 13. These sections are either integrally formed or bonded together. Heel section 13 is typically made from a stack of several layers of rubber- impregnated fabric, which give it a higher modulus of elasticity than the elastomeric sealing section 14. In prior art mud pumps, the heel section 13, which is stiffer than the elastomeric sealing section, resists extrusion into the gap between the cylinder and piston flange to some extent. However, heel section 13 is still forced into the gap under the influence of the hydrostatic pressure in locations where wear occurs. Reference numeral 18 designates a portion of heel section 14 that has been extruded into the gap 20 between the flange 11 and the cylinder 12. Both elastomeric sealing section 14 and heel section 13 make intimate contact with the cylinder 12. Seal 15 is held in place by a retaining ring 16 and a snap ring 17, which hold seal 15 in place and permit replacement thereof. Easy replacement of seals is a desirable feature for a mud pump, since seals typically wear out long before the other mud pump components and must be replaced in order to continue pumping operations. The direction of travel of piston 10 is shown by arrow 19. The direction of the hydrostatic pressure force exerted by the working fluid of the pump is shown by arrows 21. This force axially compresses elastomeric sealing section 14 and heel section 13 and radially expands these sections against the cylinder wall.

Although the invention is described with particular reference to a pump piston used with slush or mud pumps, it will be recognized that certain features thereof may be used or adopted to use in other types of reciprocating pumps. Likewise it will be understood that various modification can be made to the present seal without departing from the scope of the invention. For example, the relative dimensions of various parts, the materials from which the seal is made, and other parameters can be varied, so long as the seal retains the advantages discussed herein.
