The plain’s stratigraphy is dominated by silty clay and sandy layers, with stable geological conditions, moderate drilling resistance, and relatively low construction difficulty, making it well suited for large-scale, routine drilling operations.
In plain areas, the terrain is open and level, with a well‑organized landform and a comprehensive transportation network. The sites are spacious and free of significant topographic obstacles, allowing all types of drilling equipment to operate efficiently. Tractor‑mounted, truck‑mounted, and conventional light‑weight drilling rigs can be widely deployed in such settings. Drilling demand in plains is concentrated on agricultural irrigation, centralized water supply for villages and towns, preliminary geological surveys, and shallow‑depth resource exploration. With orderly construction sites, equipment relocation and setup are highly efficient.
From the perspective of overall industry development, plain terrains are predominantly underlain by silty and sandy strata, featuring stable geological conditions, moderate drilling resistance, and relatively low construction complexity, making them well-suited for large-scale, routine drilling operations. Supported by well-developed road networks, truck-mounted and tractor‑converted drilling rigs can swiftly relocate over short distances and flexibly switch work locations, thereby meeting the bulk drilling needs of extensive areas such as contiguous farmlands, densely populated villages, and industrial parks. Equipment maintenance, material resupply, and personnel deployment are all more convenient, and the overall construction schedule remains manageable, rendering this setting the most common geomorphological context for civil‑use drilling and small‑scale engineering exploration.
