Frequently Asked Questions

Q: What is a cement mixing skid?

A: A cement mixing skid is a skid-mounted system that mixes dry cement, mix water, and liquid additives into precisely formulated cement slurry at the required density. It features an ACM automatic mixing control system, high-energy vortex-injection mixer, and mixing tanks for batch or continuous operation.

Q: What is the ACM automatic mixing control system?

A: The ACM (Automatic Mixing Control) system is SJ Petro's advanced slurry density control technology. It provides full-auto density and liquid level control with real-time feedback and accuracy of ±0.02 g/cm³ across a density range of 1.3~2.5 g/cm³.

Q: What is the mixing capacity of the cement mixing skid?

A: The cement mixing skid delivers continuous mixing capacity from 0.3 to 2.3 m³/min (2-14.4 bpm). The batch mixing tank volume is 2×50 BBL (or 2×75 BBL optional).

Q: What is the difference between batch mixing and continuous mixing?

A: Batch mixing pre-mixes large volumes of slurry before pumping—ideal for jobs requiring precise volume control and slurry verification. Continuous mixing mixes and pumps simultaneously—ideal for extended cementing jobs requiring uninterrupted slurry delivery.

Q: What control systems are available?

A: SJ Petro offers manual simple mixing, ACM-III.1 (manual/auto), ACM-IV.1 (full-auto), and ACM-V (latest generation with advanced computer control).

Q: Can the skid be upgraded for high-density mixing?

A: Yes. The skid can be upgraded to a CAT C13 engine to meet 2.7 g/cm³ high-density mixing requirements.

Q: Is the cement mixing skid suitable for offshore operations?

A: Yes. SJ Petro produced the first skid-mounted offshore cementing equipment in China. Our skids are available with DNV certification, explosion-proof configurations (Zone II) , and marine-grade construction.

Q: What is the operating temperature range?

A: The cement mixing skid operates reliably from -20°C to +50°C.

Q: What pumping system does the skid include?

A: The skid includes two SERVA 5×6 recirculating and delivery pumps as standard. An optional SERVA 4×3 water C-pump is available.

Q: Are SJ Petro products API certified?

A: Yes. SJ Petro holds API, ISO9001, and HSE management system certifications.
