Complection Cement Plug For Oilfield

Description: Cementing Plugs are used to remove the mud during cementing operations. There are two types of Cementing Plugs used in the cementing process: Bottom Cementing Plug and Top Cementing Plug. The Top Cementing Plug has a solid body that provides positive indication of contact with the landing collar and bottom plug through an increase in pump pressure. The Bottom Cementing Plug is launched ahead of the cement slurry to minimize contamination by fluids inside the casin

The Top Cementing Plug has a solid body that provides positive indication of contact with the landing collar and bottom plug through an increase in pump pressure. The Bottom Cementing Plug is launched ahead of the cement slurry to minimize contamination by fluids inside the casing prior to cementing. Available in standard and non-rotating types.

SUMMARY 1. Provides fluid loss control in low, normal and high density cement slurries. 2. Applied below temperature of 180â?? (356â??, BHCT) 3. Features with excellent salt tolerance up to salt-saturation, suitable for both fresh and salt water system 4. When applied, cement slurry system is stable with little free fluid. 5. Has no effect of retardation on the cement slurry and ensures fast development of compressive strength of the set cement 6. Features with good fluidity, does not lead to over-dispersing or thickening and no need to add additional dispersant. 7. Compatible well with other additives. 8. Suitable for all API classes of cement. 9. Dry mixed when applied and no water quality is required. 10. Long durability, not easily affected by damp and not prone to agglomeration 11. The following technical data and parameters are of our standard type of CG610S-D. We are capable of catering tailor-made products and services upon receipt of customersâ?? individual requirements . CEMENT SLURRY PRESCRIPTION Cement Slurry Density Recommended Dosage in Fresh Water and Moderate Temperature System Recommended Dosage in 18% Slat Water and Moderate Temperature System Recommended Dosage in 18% Salt Water and High Temperature System STANDARD PACKAGING AND STORAGE 1. Packed in 25kg bag. It can also be packed according to customerâ??s different individual demands. 2. Use within 24 months after production. When expired, lab test should be conducted to confirm the quality before use. 3. Store in ventilated, cool and dry area, avoid exposing to sun and rain. The height of stack should be less than 8 layers.

After drilling, we need to pump the cement to the well to cementing , In the Wells of high temperature and high pressure environment, in order to ensure the performance stability of the slurry, used the cementing additives.

The casing cement-head with double plugs (called as cement-head ) is a common cementing tool used as wellhead unit in all kinds of cementing operation. Comparing to cement-head with single plug, it owns longer cement-head body , and upper rubber plug and lower rubber plug can be put in at same time. The tool owns some advantages such as simple construction, easy operation, high pressure resistant, manifold in common use, flexible in connecting. Especially, the lever type indicator can shows whether rubber plug goes through double plugs cement-head to enter casing so that operator can determine easily.

Property Kol-rtd m cem can absorb on the surfaces of cement hydrate to inhibit contact with water and on the surfaces of crystal nucleis to prevent their increase. So it can retard hydrating of cement slurry.
