Friction and wear behaviors of sand particle against casing steel

Abstract

Tools abrasive wear due to sand particles has caused severe damage during oil and gas exploitation. The friction and wear behaviors of single quartz sand particle against N80 casing steel were investigated to estimate the particle transport resistance and particle abrasive wear behavior using a homemade tribometer in wellbore sand cleanout. Various measurements were conducted to research the impact factor of particle under different water processing condition, dry, short immersion, wet, influences of load and slide velocity. Experimental results indicated that particle-casing friction resistance is mainly formed due to plowing and adhesion effect. Casing transfer and plowing removal are two main damage forms. Particle real contact area increases noticeably after water absorption, which decreases the hertz contact stress and finally produces less plowing depth of casing steel and causes less damage. With load increasing, friction resistance and wear increase with addition of plowing depth. A simple particle-casing friction model was established considering the experimental contact behavior.

Research on microstructural‐mechanical and shearing properties of castor seed during mechanical extraction

“…This is due to the endosperm structure of organic material with element (C H O) embeds into the concave zone during seed shear. This also corresponds to the images shown in Figure 12e,f, the endosperm plowing and tissue residue on iron surface (Yang et al, 2019;Yang et al, 2021).…”

Wear factors and mechanisms of L-80 steel casings

“…They studied the effect of drill pipe rotational speed, contact force, and casing material grade on casing wear depth and established a wear prediction model. Another study was conducted by Yang et al [12] to investigate friction and wear taking place between N80 casing steel and a single quartz sand particle. The results showed that the observed friction is most likely formed owing to adhesion and plowing effect.…”

The Excellent Mechanical Performance of Polymer-Coated Ceramsite Particles for Efficient Fracturing: An Explanation from a Surface, Tribological Perspective

“…Hydraulic fracturing is an effective technique to improve oil recovery in the petroleum industry [ 1 , 2 , 3 , 4 ], which is the process of pumping a fracturing fluid (typically composed of water, particles, and certain chemicals) into a wellbore at very high pressures to rupture rocks and create many fractures [ 5 , 6 , 7 , 8 ]. While the fracture crack is formed, many particles (called proppants) are pumped into the fracture along with the fracturing fluid at a high flow of about 15~16 KL/min [ 9 ] and rapidly migrate to the crack and become stuck in the crack.…”

“…In previous research, we have studied the contact behavior between sand particles and sand cleaning tools in the oil/gas industry from the perspective of tribology [ 4 , 20 , 21 ]. Due to the increasing demand and production of shale oil and gas, the characterization of proppant particles is essential to prove and demonstrate that the shale bed cracks are closely related to hydraulic fracturing [ 22 ].…”
