III. General Product Overview

Well‑flushing trucks and well‑flushing & wax‑removal trucks are core special truck‑mounted equipment for daily operation‑and‑maintenance, stable‑production and output enhancement of oilfields. Refitted on heavy‑duty off‑road chassis, the equipment integrates high‑pressure pumping, thermal cleaning, circulating filtration, intelligent electronic control and liquid‑storage‑recovery systems. It is mainly applied for wellbore cleaning of oil wells, wall wax deposition removal, pipeline scale removal, impurity sweeping and blockage dredging and other workover operations.

Compared with traditional manual wax removal and simple flushing methods, the integrated truck‑mounted equipment delivers fast relocation and high automation with thorough cleaning performance. It effectively solves problems such as wax‑caused blockage of oil wells, high water‑injection pressure, production decline and poor pipeline flow. The full product range adapts to complex field conditions including gobi, desert and extreme temperatures. Widely used in regular maintenance of various oil and gas wells in onshore oilfields, it is essential equipment for oilfield stable‑production and efficiency improvement.

IV. Introduction to Core Individual Units

1. Well‑Flushing Truck (High‑Pressure Circulating Well Flushing)

Special truck‑mounted high‑pressure well‑flushing equipment integrated with high‑pressure pumping, liquid circulation, filtration‑purification and constant‑pressure control systems. It focuses on conventional operations including overall wellbore cleaning, pipeline flushing, sand washing & impurity removal, pressure testing and well drifting. With stable pressure output and large flushing flow rate, it thoroughly removes sediment impurities, oil contamination and scale blockages inside wellbores, dredges wellbore passages and restores normal working conditions of oil wells. Simple‑to‑operable, the whole unit supports single‑person operation workflow. It features flexible relocation and high construction efficiency, suitable for high‑frequency daily well‑flushing, well‑drifting and maintenance operations in oilfields.

2. Well‑Flushing & Wax‑Removal Truck (Thermal‑High‑Pressure Wax & Scale Removal)

Multi‑functional integrated special‑purpose equipment for well flushing and wax removal. Based on conventional well‑flushing functions, it is equipped with thermal heating system and high‑pressure cleaning system to target oil‑well wax deposition problems. Adopting dual‑process of constant‑temperature thermal melting plus high‑pressure water‑jet scouring, it rapidly removes stubborn paraffin, colloid, asphaltene and heavy dirt inside tubing, casing and well walls. It fundamentally addresses wax blockage, poor oil output and rapid production attenuation of oil wells. Supporting closed‑loop circulating operation with filtered and recycled sewage, it is energy‑saving and eco‑friendly without damaging well walls and pipe strings. It delivers thorough wax removal and long‑lasting stable‑production effect, serving as core equipment for special maintenance of heavy‑oil wells and high‑wax‑content wells.

V. Core Product Advantages

1.Multi‑Purpose Design with Wide Operation Coverage

The two models feature clear division of labor and complementary functions to fully cover conventional oilfield maintenance operations. Capable of well flushing, sand washing, well drifting and pressure testing, they also perform difficult wax‑deposition elimination, heavy‑oil‑dirt cleaning and pipeline dredging, satisfying multiple demands including daily oilfield maintenance, fault dredging and production‑enhancement reconstruction.

2. Combination of High Pressure and Thermal Energy for Thorough Cleaning

Equipped with high‑pressure plunger pumping system with sufficient pressure and strong scouring force. The wax‑removal model is fitted with constant‑temperature heating system to rapidly melt stubborn wax layers and colloidal dirt. The dual‑process delivers strong penetration and dead‑angle‑free cleaning, effectively dredging blocked wellbores and cleaning pipe walls and pipelines, greatly improving oil‑well permeability and recovery rate.

3. Truck‑Mounted High‑Efficiency Mobility for Convenient Construction

Built on mature off‑road chassis with flexible field relocation and excellent trafficability. Construction can start upon arrival without cumbersome disassembly and assembly. High integration and automated operation reduce labor dependence, shorten single‑well operation cycle and realize fast maintenance and rapid production restoration. Suitable for large‑scale and high‑frequency well‑site operations in oilfields.

4. Closed‑Loop Circulating Construction for Green & Energy‑Saving Performance

Fitted with liquid circulation and filtration‑recovery systems for recyclable working media, greatly cutting water consumption. No waste‑liquid discharge or dust pollution occurs during construction. Environment‑friendly and compliant with oilfield green‑construction standards, it effectively eases on‑site environmental‑protection pressure for operation‑and‑maintenance.

5. Strong Working‑Condition Adaptability, Stable‑Durable & Easy‑to‑Maintain

Optimized for harsh field environments with anti‑corrosion pipelines, dust‑proof & water‑proof electronic control components, whole‑unit resistance to extreme temperatures and anti‑shock performance. Modular layout delivers neat structure with clear fault points for easy daily maintenance and high field attendance rate. It can stably operate for long periods under complex well‑site conditions such as gobi, desert and plateau.

VI. Application Scenarios

• Daily Oil‑Well Maintenance: Perform conventional well flushing, well drifting, sand washing, scale removal and pressure‑testing operations to regularly clear wellbore impurities and stabilize well conditions.

• Special Treatment for High‑Wax‑Content Wells: Efficiently melt and remove wall wax layers and colloidal blockages for heavily‑wax‑deposited oil wells to solve production decline caused by wax blockage.

• Production‑Enhancement Reconstruction for Old Wells: Clean heavy oil contamination, scale and blockages in aged wellbores to unblock seepage passages and effectively restore productivity of old wells.

• Field Construction at Complex Well Sites: Adapt to remote wells, scattered wells and field conditions with extreme temperatures and sandstorms for fast relocation and high‑efficiency construction.

VII. General Technical Parameters (Standard Configuration｜Customization Supported)

Below are standard‑configuration parameters for the two equipment models. Custom upgrading is available according to well‑site conditions, pressure requirements and low‑temperature environments.
