“…The concept of high-performance water-based drilling fluids (HPWBF) (Galindo et al 2015;Jain et al 2015;Jung et al 2013;Kosynkin et al 2011;Morton et al 2005) has been proposed for decades. HPWBF is defined as water-based drilling fluids (WBF) with good performance parameters, such as good rheology, low filtration, strong shale inhibition, good lubricity, good plugging property, etc., which are important for safe and efficient drilling.…”

High-performance water-based drilling fluids (HPWBFs) are essential to wellbore stability in shale gas exploration and development. Laponite is a synthetic hectorite clay composed of disk-shaped nanoparticles. This paper analyzed the application potential of laponite in HPWBFs by evaluating its shale inhibition, plugging and lubrication performances. Shale inhibition performance was studied by linear swelling test and shale recovery test. Plugging performance was analyzed by nitrogen adsorption experiment and scanning electron microscope (SEM) observation. Extreme pressure lubricity test was used to evaluate the lubrication property. Experimental results show that laponite has good shale inhibition property, which is better than commonly used shale inhibitors, such as polyamine and KCl. Laponite can effectively plug shale pores. It considerably decreases the surface area and pore volume of shale, and SEM results show that it can reduce the porosity of shale and form a seamless nanofilm. Laponite is beneficial to increase lubricating property of drilling fluid by enhancing the drill pipes/wellbore interface smoothness and isolating the direct contact between wellbore and drill string. Besides, laponite can reduce the fluid loss volume. According to mechanism analysis, the good performance of laponite nanoparticles is mainly attributed to the disk-like nanostructure and the charged surfaces.

In the experiment, the filtrate loss of synthetic fluid loss control fluid was recorded in room temperature and high temperature in the composite brine base and sodium chloride brine base slurry, and compared with the filtrate loss before base polymer addition. In this way, the effect of filtration loss and salt resistance and temperature resistance of synthetic polymers were evaluated. The influence of the synthesized polymer on the rheological properties of the composite brine was also evaluated by determining the viscosity of the drilling fluid added to the base slurry and polymer. In the end, the structure of the synthetic polymers was characterized through the infrared spectrum, which initially analyzed through the mechanism of its function in reducing the filter loss. Finally, the products produced according to the recipe are given to the site and added to the two wells to record the drilling fluid performance data.

“…However, these drilling fluids have many kinds of limitations in inhibiting shale swelling and hydration [5][6][7]. In recent years, a novel type of high performance water-based drilling fluid system is introduced which is mainly composed of organic amine shale hydration inhibitor, cationic polyacrylamide encapsulator, rheology modifier, and lubricant and filtration reducer.…”

An organic amine inhibitor was developed and evaluated. Experimental results showed that the organic amine inhibitor could decrease the surface tension to 50mN/m and had a little effect on the Zeta potential of clay. The inhibitor could effectively inhibit the dispersion of core and cuttings and had a lasting strong inhibition. The inhibitor had good compatibility with common drilling fluid, and it was useful to maintain drilling fluid stability under high temperature and could improve the filtration property of drilling fluid.
