In the process of drilling in soft layers, the squeeze expander is a very effective hole expansion tool, which is specially used for soft, muddy or water-rich formations. The squeeze expander avoids the common wellbore collapse or hole instability in soft layers by squeezing and expanding the hole instead of direct cutting.
Product features：
1. Extrusion expansion: The extruder uses hydraulic or mechanical pressure to squeeze the formation material outward to expand the hole diameter. Unlike traditional cutting expansion, the extruder avoids direct cutting and can expand the hole diameter more stably in soft formations.
2. Smooth wellbore: After the extruder expands the hole, the wellbore wall is usually smoother, the hole wall strength is enhanced, and the risk of wellbore collapse is reduced. This is especially important in soft bottom drilling and helps to improve the stability of the wellbore.
3. High adaptability: The extruder is designed to be suitable for a variety of soft formations, including sand layers, clay layers, and water-containing or muddy geological environments. It can avoid problems such as excessive hole expansion, hole wall deformation, or formation flow.
4. Multiple specifications design: The extruder has various sizes and expansion ranges according to different formation requirements, adapting to different drilling diameters, and suitable for a variety of wellbore diameters and engineering applications.
