Application Areas
Our modular designs shine in challenging logistics environments:
-
Infrastructure-Limited Remote Regions: Deep jungle, desert, or mountainous areas where road widths or bridge weight limits restrict heavy-load transport.
-
Multi-Well Pad Drilling: The rapid rig-up capability allows you to literally "pick up and move" the entire rig between wells on a single pad in a matter of hours, saving massive operational costs.
-
Offshore Platform Tender Drilling: Our lightweight modular substructure modules are ideal for tender-assisted drilling (TAD) on jack-up platforms or production platforms with limited crane and deck space.
-
Fast-Track Exploration Projects: When oil prices are high and you need to spud a well in 90 days, our modular rigs are the fastest route from port to drilling.
Product Types
We offer specific modular configurations to match your operational constraints:
-
Containerized Modular Rig (CMR): The ultimate in transportability. The entire rig, including the draw works and control cabin, can be broken down into standard 40ft HC containers.
-
Box-on-Box Modular Substructure (BBS): A robust, heavy-duty design using stacked box modules. This allows for high hook loads (4500kN+) while maintaining the ability to flat-rack ship.
-
Slingshot Modular Mast (SMM): A unique cantilever design where the mast flicks into position hydraulically. Requires no remote crane for mast erection, saving additional lifting costs.
Why Choose Sinopec's Modular Drilling Rigs?
-
A True Integrated Supply Chain: We manufacture the mast, the substructure, and the mud system ourselves. This ensures that the bolt holes between the pump skid and the sub-base align perfectly the first time, avoiding delays during assembly in the field.
-
Proven Global Logistics Track Record: We have shipped complete modular rigs to 6 continents using standard shipping methods. We can provide you with specific weight and dimension data to expedite your logistics permits and customs clearance.
-
Long-Term Serviceability: Modular doesn't mean "disposable." We maintain a massive inventory of replacement wear parts for all modular components, meaning a broken connection pin in Uzbekistan can be shipped in 48 hours.
-
Scalable to Your Project: Our modular design is highly scalable. You can start small with a 3000m rig and later add additional modules to the same base structure to upgrade it to 7000m capability.
Frequently Asked Questions (FAQ)
Q: How many containers does it take to ship a complete modular drilling rig?
A: For a standard ZJ50 (5000m) modular rig, you can expect roughly 40 to 60 containers (40ft HC), depending on whether you include the mud circulating system or source it locally.
Q: Can your modular rigs be assembled without a large mobile crane?
A: Yes, that's a core design feature. The mast uses a self-erecting "jack-up" or "slingshot" mechanism often powered by a hydraulic power unit (HPU) that comes with the rig package. The modules themselves can often be moved into position using standard forklifts or smaller rough-terrain cranes.
Q: What is the foundation requirement for a modular rig?
A: Generally, a flat, leveled concrete pad (or steel grillage) is sufficient. Because the modular base distributes weight differently than a solid skid, we can provide the exact point load calculations required for your civil engineer to pour the foundation.
Q: Is the electrical wiring modular as well?
A: Yes. We utilize quick-connect, heavy-duty industrial cable plugs interlocked with the mechanical modules. This eliminates on-site cable tracing and drastically reduces the risk of electrical mismatch.
Q: What is the difference between your "Modular" rig and a standard rig?
A: A standard rig is often a single welded unit requiring heavy lifts to move. A modular drilling rig is built from separate, transportable building blocks joined by pins/bolts. The main benefits are vastly superior ease of transport and massively faster rig-up/rig-down times.
