Abstract: The large-scale application of effective proppant fracturing technology—characterized by large fluid volume, large displacement, and large sand volume in CBM wells of the South Yanchuan Block has significantly shortened the gas production cycle and enhanced economic efficiency. However, it also induced severe formation sand production and frequent pump inspections. To address this challenge, a low-temperature consolidation sand (HDCS-L) was developed in the laboratory using quartz sand, epoxy resin, modified aliphatic amines, polyethylene glycol, and other raw materials through surface modification and physical coating methods. Key properties including consolidation time, consolidation temperature, consolidation strength, and flow conductivity were systematically evaluated. Experimental results demonstrate that HDCS-L achieves a consolidation strength of 5.69 MPa after 24 hours at 30 ℃ under atmospheric pressure. Under pressurized conditions (30 ℃, 10 MPa, 24 hours), the consolidation strength increases to 12.17 MPa with a flow conductivity of 8.82 mD·cm, confirming its robust consolidation capability and permeability retention after low-temperature curing. Field application in 7 wells demonstrated a 100% success and efficiency rate. Specifically, Well Y-11 maintained effectiveness for over 240 days, and Well Y-21 achieved stable production for more than 180 days. This study validates that HDCS-L is suitable for the integrated fracturing-drainage process in South Yanchuan CBM wells, demonstrating promising application potential.
