Product Details

Liquid Lubricant

1. Product Overview

Liquid Lubricant is a high-performance additive formulated from animal/vegetable oil derivatives, synthetic compounds (e.g., fatty phenolamines) and surfactants. Designed for both water-based and oil-based drilling fluid systems, it forms a protective oil film on metal, rock and clay surfaces, converting solid friction into low-resistance oil film friction. It significantly reduces drill string torque, prevents sticking incidents, improves drilling efficiency and extends tool service life.

Application Cases of Liquid Lubricants for Drilling Fluids

1. Torque Reduction and Anti-sticking Case for Directional Wells with Conventional Water-based Drilling Fluids

Case Background: Conventional directional deflection wells have complex wellbore trajectories and variable curvature. The water-based drilling fluid itself has poor lubricity, resulting in high sliding friction during deflection construction, large downhole torque and obvious stick-slip phenomenon. It is easy to cause unstable tool face control, slow directional footage and increased risk of differential pressure stuck pipe, which seriously affects directional drilling efficiency and construction safety.

Application Formula & Dosage: On the basis of conventional water-based drilling fluid system, 0.5%–1.2% liquid lubricant was added. The product is fully compatible with bentonite water-based systems, which can quickly improve the lubricating performance of drilling fluid and optimize downhole friction conditions.

Application Effect: The liquid lubricant can be uniformly dispersed in the drilling fluid and form a dense molecular lubricating isolation film on the surface of drill string and mud cake. It effectively reduces the friction coefficient between drill string and wellbore, significantly reduces directional sliding torque and tripping drag, eliminates stick-slip vibration, improves tool face adjustment accuracy and response speed. It effectively prevents differential pressure stuck pipe accidents, stabilizes wellbore trajectory, and greatly improves the construction efficiency of directional wells.

2. High-efficiency Drag Reduction and Speed Increase Case for Extended-reach Horizontal Well Water-based Drilling Fluids

Case Background: Extended-reach horizontal wells have ultra-long horizontal open-hole sections, long drilling fluid soaking time, and large contact area between drill string and well wall. The conventional water-based drilling fluid has insufficient lubricating capacity, resulting in continuous increase of downhole drag and torque during long-distance drilling, difficult horizontal section extension, low mechanical drilling speed and high downhole complex risk, which restricts the efficient development of long horizontal well construction.

Application Method & Dosage: 0.8%–1.5% high-efficiency emulsified liquid lubricant was applied in horizontal well water-based drilling fluid systems. It adopts strong adsorption and film-forming technology to achieve long-term continuous lubrication and solve the problem of insufficient lubricity of water-based systems.

Application Effect: The product has excellent dispersion and adhesion, which can form a tough anti-friction lubricating film on the wellbore wall for a long time, effectively reducing the overall downhole friction and drag of long horizontal sections. It significantly improves the lubricating coefficient of water-based drilling fluid, reduces the burden of drilling tools and surface equipment, improves the horizontal section extension capacity and mechanical drilling speed, shortens the drilling cycle, and ensures safe and stable construction of ultra-long horizontal wells.

3.  Anti-pollution Stable Lubrication Case for Low-salt Complex Formations

Case Background: Low-salt and brackish water-bearing complex interbedded formations have certain ion interference. Conventional lubricants are prone to demulsification, layering and performance attenuation under salt pollution, resulting in unstable drilling fluid lubricating performance, fluctuating downhole torque, and poor lubricating effect in the later stage of circulation, which cannot meet the requirements of long-cycle stable drilling of salt-bearing complex formations.

Application Dosage: 0.6%–1.3% salt-resistant liquid lubricant was added to brackish water drilling fluid systems. It has strong electrolyte resistance and good system compatibility, and can maintain stable lubricating performance in low-salt contaminated environments.

Application Effect: The salt-resistant liquid lubricant will not demulsify or fail in low and medium salinity environments. It can stably maintain the high lubricating coefficient of the drilling fluid system during long-term circulating drilling, effectively suppress downhole torque fluctuation and friction increase, avoid poor lubrication caused by salt pollution, ensure consistent downhole lubricating effect throughout the drilling cycle, and reduce downhole complex risks in salt-bearing formations.

4. Low-damage and Environment-friendly Lubrication Case for Medium-low Temperature Reservoirs

Case Background: Medium-low temperature oil and gas reservoirs, especially low-permeability fine pore throat reservoirs, are sensitive to drilling fluid additives. Conventional oily lubricants are prone to oil phase residue, pore throat blockage and fluorescence interference, resulting in reduced reservoir permeability recovery rate, poor logging interpretation effect and increased reservoir damage, failing to meet low-damage protective drilling standards.

Application Method & Effect: Environment-friendly low-fluorescence liquid lubricant was applied at 0.5%–1.0% in reservoir protection drilling fluid systems. The product has low fluorescence, low residue and high degradability. While efficiently improving the lubricating performance of drilling fluid, it will not block reservoir pore throats or interfere with logging data. It features low reservoir damage and high core permeability recovery rate, realizing green and low-damage lubricating drilling.

5. Long-cycle Circulating Stable Lubrication Case for Medium-temperature Deep Wells

Case Background: Medium-temperature deep wells have long downhole circulation time and continuous high-temperature shearing of drilling fluid. Conventional common liquid lubricants are prone to thermal decomposition and lubrication failure after long-term thermal rolling, accompanied by system foaming and rheological changes, resulting in late-stage downhole friction surge and increased tripping resistance, which affects the safe completion of deep well drilling.

Application Method & Effect: The conventional dosage is 0.7%–1.4%. The medium-temperature resistant liquid lubricant has stable molecular structure and strong shear resistance. After long-term high-temperature circulation, the lubricating performance does not decay, and it will not cause foaming and thickening of the drilling fluid system. It stably controls downhole friction and torque throughout the whole drilling process, reduces downhole wear and complex accidents, and ensures long-cycle safe and stable drilling of medium-temperature deep wells.
