During the gas extraction drilling process, especially the soft coal seam drilling process, due to the constraints of geological conditions, technical conditions, and other factors, it is easy to encounter stuck holes, blowout, lost circulation, and hole collapse, which affect the realization of efficient gas management. In the petroleum industry, microfoam drilling fluid has unique advantages as a drilling and flushing medium. Through the response surface method, this study conducts a preliminary experimental study on the types of foaming agents, foam stabilizers, modified bentonite materials, and filtrate reducers and determines the optimal formula as 3.98% modified bentonite + 0.586% compound foaming agent + 0.776% foam stabilizer + 1% sulfonated phenolic resin + 2% carboxymethyl starch sodium. The performance of the microfoam drilling fluid system is tested. Subsequently, a simulated soft coal seam drilling test is carried out to verify the effectiveness of the developed directional microfoam drilling fluid for protecting coal rock holes. This microfoam drilling fluid system technology can improve the drilling quality of the sealing section of coal seam gas extraction drilling and effectively improve the gas extraction rate of coal mines.

A colorimetric sensing platform based on carboxymethyl cellulose-silver nanoparticles (CMC-AgNPs) metallogel was proposed to monitor the temperature history and quality of perishable products stored at low temperature. The carboxymethyl cellulose (CMC) metallogel, fabricated in the presence of Ag+, incorporates ionic crosslinking of biopolymers, complexation between reactants, and subsequent in situ synthesis of AgNPs, which are designed to lead the color transition of metallogel from colorless to dark brown depending on temperature and time. The mechanical and structural properties of metallogels and AgNPs were characterized by rheology, XRD, and FT-IR. Color changes associated with temperature, time, and metal ion precursors were examined by UV–visible spectroscopy and colorimetry. The longer the exposure time to thermal stress condition such as room temperature (25 °C) or high temperature (60 °C), the deeper the color of metallogel. The CMC-AgNPs metallogel-based sensor provides an efficient, safe way to track temperature history and assess perishable products’ quality, crucial for the safe distribution of food, vaccines, and medicines. This cost-effective and reliable visual sensor minimizes spoilage and health risks by enabling accurate temperature monitoring without the need for complicated equipment.
