Si-driller control system

Technical Specifications

Product Types & Configurations

We offer Si‑driller in several hardware and software tiers. All include the same core algorithms – the difference is in ruggedness, I/O count, and remote features.

Software option packages:

• Directional drilling add‑on – interfaces with RSS toolface and inclination sensors.

• Casing running assistant – optimized slow‑speed mode with torque limiting.

• Remote drilling center license – allows a single operator to monitor and control up to 10 rigs from an office.

Application Areas

[Insert Product Image 04: Si‑driller screen showing drilling optimization dashboard]

Onshore conventional drilling – The classic use case. Si‑driller replaces old mechanical auto‑drillers or manual drilling. One driller in West Texas reduced his daily tripping time by 11% simply because he drilled straighter holes with fewer corrections.

Horizontal & directional drilling – The stick‑slip control is critical when sliding with a mud motor. Several operators in the Permian report 30% faster slide drilling after switching to Si‑driller.

Offshore platform & jack‑up rigs – The Pro version with stainless steel console and redundant power is approved for North Sea operations. The remote monitoring feature allows onshore drilling engineers to see real‑time data without flying offshore.

High‑pressure / high‑temperature (HP/HT) wells – The predictive bit wear model and tight WOB control helps maintain near‑constant BHA loading, reducing the risk of stuck pipe in narrow margin HP/HT windows.

Training & simulator rigs – Many drilling schools use Si‑driller Lite in simulator mode to teach students the principles of automated drilling without risking real equipment.

Why Choose SJ Petroleum Machinery Co., Ltd.?

1. Built by drillers, for drillers – Our lead controls engineer spent seven years as a rig manager before moving into software. He knows exactly why most auto‑drillers frustrate crews – and fixed those problems in Si‑driller. The interface is logical, the manual override is immediate, and the help screens are actually helpful.

2. Proven on 120+ rigs, 6 continents – No "lab only” system. Si‑driller has drilled over 3 million meters in commercial service. We have a library of field reports, performance comparisons, and customer references ready for serious buyers.

3. Works with your existing sensors – no forced upgrades – We support most common pressure transducers, load cells, encoders, and proximity sensors. If you have a sensor, we can read it. If you don't have a sensor, we can supply it cheaply. No need to rip out your current instrumentation.

4. Open architecture – no vendor lock‑in – The system logs data in standard CSV and WITSML formats. You own your data. We don't charge licenses for accessing your own logs. You can export to any third‑party software (Spotfire, PowerBI, WellView, etc.)

5. Affordable pricing, transparent breakdown – A full Si‑driller Standard system costs less than half of comparable Western brands, with the same or better performance. We provide a line‑item quote: hardware, installation kit, software license, training, and optional remote support. No hidden "per‑rig” annual fees for basic functions.

6. Rapid retrofit – typical installation 2–3 days – We pre‑configure the system at our factory based on your sensor map and control valve specifications. On site, our technician (or yours with our remote guidance) mounts the console, wires the I/O, and tunes the PID parameters in 16‑24 hours. Full training on day two.

Frequently Asked Questions (FAQ)

Q1: Can Si‑driller be installed on a mechanical rig with no existing automation?
Yes. For mechanical rigs (chain drive, air clutches, hydraulic throttle), we supply a "proportional actuator kit” that converts your existing throttle and brake controls to accept a 4‑20mA signal from Si‑driller. You keep your original hand levers for manual override. We have done this on 1970s vintage rigs.

Q2: Does it work with rotary steerable systems (RSS)?
Yes, with the directional drilling add‑on package. Si‑driller reads toolface and inclination from the RSS telemetry system (via serial or WITS) and adjusts rotary speed and WOB to maintain the required build/drop/turn rate while minimizing torque variation.

Q3: How accurate is the bit wear prediction?
It is not a replacement for real‑time dull grading, but field tests show it predicts "pull bit now” within 5–10% of actual useful life remaining. The model improves as it learns your specific formation and bit type. After three wells in the same field, accuracy reaches ±8%.

Q4: What happens if the touchscreen fails in the middle of drilling?
You have two backups: 1) A physical emergency stop and a "Manual” toggle switch that disables all automation and returns control to conventional levers. 2) The system continues to hold the last setpoints until you manually change them – drilling does not stop. Replacement touchscreens are stocked globally.

Q5: Can I connect Si‑driller to the rig's existing PLC or SCADA system?
Yes. We support Modbus TCP, OPC UA, and raw serial protocols. Many customers feed Si‑driller's setpoints to their existing PLC, which actually moves the drawworks. Others use Si‑driller as the primary controller and output directly to drive cabinets. Tell us your PLC brand and model.

Q6: Is training included?
Our standard package includes two days on‑site training for up to six people (drillers, toolpushers, maintenance). The training covers: system overview, daily operation, setpoint tuning, fault diagnosis, and manual override. We also provide a 2‑hour interactive simulator for new hires. Additional training weeks are available at hourly rates.

Q7: How much maintenance does the control system require?
Very little. The PC cabinet has no moving parts (solid state drive). Clean the touchscreen weekly with a soft cloth. Check cable connections monthly. Replace the backup battery (for real‑time clock) every three years. That's it. We have units running 24/7 for 18 months without a single software reboot.

Q8: Do you offer a trial period or money‑back guarantee?
We offer a 60‑day performance trial for qualified operators. You install Si‑driller on one rig, drill at least two wells (or 30 days of rotating). If you are not satisfied with the performance improvement (ROP gain, reduction in drilling dysfunctions), return the hardware for a full refund minus shipping. No questions asked.

Q9: Can I upgrade from Lite to Standard or Pro later?
Yes. The software is the same; only the hardware I/O capacity differs. You can start with Lite to test the algorithms on a workover rig, then trade in the tablet for a full console and pay the price difference. We also allow software‑only upgrades (unlocking more I/O channels in the same PC) if your hardware already has the capacity.

Q10: What technical support is available after purchase?

• First year: Free 24/7 phone/email support, remote desktop assistance, and one preventive maintenance visit.

• Years 2–5: Annual support contract (optional, ~15% of system price) includes same plus software updates and hardware warranty extension.

• Per‑incident support: $250/hour, one‑hour minimum.
  We maintain a knowledge base with common issues, wiring diagrams, and software updates accessible with your serial number.
