CNPC's major drilling and production equipment includes drilling rigs, drilling bits, geosteering systems, downhole tools, mud pumps, top drive devices, solid control devices, cementing trucks, fracturing trucks, oil well pumps, pumping units and pumping rods. All our flagship products have received ISO9001 QMS certification.

Drilling Rigs

CNPC has over 40 years of experience in designing and manufacturing drilling rigs since 1970s. We produce various types of drilling rigs including AC VFD, DC, diesel engine and gear, chain, hydraulic and belt drive, truck-mounted and trailer-mounted series, ranging from 1,000 meters to 12,000 meters in drilling depth.

New technologies including disk brake, AC VFD, SCR, dynamic braking, automatic driller and integrated drilling meters have been applied.

Mud Pumps

CNPC produces a series of API7K-compliant mud pumps ranging from F-500 to F-2200. F-2200HL is a tri-cylinder, single-action, heavy-duty, high-pressure drilling pump with a maximum power of 2,200HP, maximum working pressure of 52MPa, and maximum displacement of 77.65L/s. CNPC owns the intellectual property rights of this modern and high-tech product.

  F-1300, F-1600, F-1300L and F-1600L mud pumps have a Max. pump pressure of 34.5MPa (5000Psi) and a displacement of 46.5L/S with a liner of Φ180mm. These two models are the first choice for medium and deep drilling rig as an assorted component.

  F-1600HL, F-2200HL mud pumps with high-power and high-pressure are developed to meet drilling requirements of offshore deep-water, terrestrial and horizontal wells, especially in desert areas.

  F1-800, F1-1600 light- weight series mud pumps are newly designed. Compared with same power F-series mud pumps, the advance of less volume and weight which are appropriate for the rigs working in swamp and helicopter-lifting rigs.

  QDP-3000 five-cylinder mud pumps, with large power, high pressure, big displacement, small size and light weight, are especially suitable for offshore platform and drill ship.

Geosteering System   

CGDS-I, a near-bit geosteering system for well drilling, has been independently developed by CNPC. The CGDS-1 Near-bit Geosteering System has worked normally for 297 hours in the well bores of Liaohe Oilfield, satisfying the needs on the well site.

CGDS-I consists of the CAIMS (China Adjustable Instrumented Motor System), WLRS (Wireless Receiver System), CGMWD (China Geosteering MWD), and the CFDS (China Formation/Drilling Software System). CGDS-I has three major functions: logging/measurement, transmission and steering. The system's near-bit geological and engineering parameters and sensor-bit distance measured in industrial tests carried out at the Jidong and Liaohe oilfields reached or approached those of the world's other leading instruments in this field.

Precise PCD system

The system consists of a ground pressure control device (model PCDS-I and CQMPD-I) and downhole pressure logging-while-drilling (LWD) tools. In near- and under-balanced precise pressure controlled drilling (PCD), it monitors and controls the annular pressure and compensates for backpressure to avoid complex situations such as well kick and loss of circulating fluid in narrow windows of drilling fluid density.
