I. Introduction to 3TP Mud Pump
3TP series mud pumps are designed for oil and gas drilling, horizontal directional drilling (HDD) construction, water well drilling, coal seam grouting, and other fields.
Adopting the design concept of long stroke and low stroke rate, it uses a lower stroke rate compared to traditional mud pumps at the same flow rate, reducing overall wear on the power end and its components, and improving the pump's overall performance and durability.
· Low stroke rate means fewer reciprocating movements, significantly reducing fatigue and wear on key components such as the power end crankshaft, connecting rods, and crossheads.
· For water well/geothermal well construction, this directly translates to longer continuous operation time and less downtime for maintenance, especially in deep well construction ranging from hundreds to thousands of meters, effectively avoiding schedule delays caused by pump failures.
The power end adopts a three-crank, four-bearing design, providing higher load-bearing capacity and longer maintenance intervals.
· This design ensures more balanced stress on the power end and stronger impact load resistance, making it more capable of handling high-pressure and high-resistance conditions during deep well drilling.
· For customers, this means more stable equipment operation, lower failure rates, and long-term savings on maintenance labor and spare parts costs, thereby reducing operating costs.
Larger piston diameters and lower stroke rates result in longer service life for wearing parts such as valves and pistons.
· Key Advantage: High sand content in mud leads to rapid wear on valve seats, valve discs, pistons, and cylinder liners. Large pistons and a low stroke rate significantly extend the replacement cycle of wearing parts, directly reducing consumable costs and downtime losses for customers.
Aimed at achieving lower operating costs.
Mud Pump Selection Factors
Recommendations Based on Well Depth and Borehole Diameter
Shallow Section: 100-300m (mainly soft formations, agricultural water wells / shallow geothermal)
Operating Characteristics
Low pipeline friction resistance, low formation pressure; core requirements are high flow rate for sand removal and stable flow for wellbore protection.
Conventional Borehole Diameter: Φ150-Φ450mm, mainly small to medium diameters.
孔径范围 Borehole Diameter Range | 推荐3TP泵型 Recommended 3TP Pump Model | 额定排量 (L/min) Rated Displacement (L/min) | 最高工作压力 (MPa) Maximum Working Pressure (MPa) | 核心适配优势 Core Adaptation Advantages |
Φ150~Φ250mm | 3TP-1200S | 1200 | 8 | 小口径井精准匹配，流量充足，压力储备完全覆盖 300m 井深需求，整机体积小、安装便捷 Precise match for small diameter drilling, sufficient flow, pressure reserve fully covers the 300m drilling depth requirement, compact size, and easy installation. |
Φ250~Φ450mm | 3TP-1800S | 1500（最大 1800） | 9 | 大口径井大流量携砂，9MPa 压力预留充足安全余量，适配软地层大排量循环需求 High flow rate for sand removal in large diameter drilling, 9MPa pressure provides ample safety margin, matching high-displacement circulation needs in soft formations. |
At the same flow rate, 3TP-1800S is 40% lighter and uses 25% less power than F-500, resulting in lower fuel/electricity costs.
Traditional double-cylinder reciprocating pumps have high flow pulsation, which can easily wash out soft formation wellbores. The 3TP series triplex structure has a 60% lower pulsation rate, significantly improving wellbore stability.
Medium Section: 300-600m (alternating soft and hard layers, conventional geothermal / deep water wells)
· Formation Characteristics
Significant increase in pipeline resistance, deteriorating formation stability; core requirements are stable flow at medium-to-high pressure and balanced flow for sand removal.
Conventional Borehole Diameter: Φ200-Φ500mm, covering most civil/commercial deep water and geothermal wells.
