Mobile Trailer Portable Water Well Drilling Rig Core Drill Machine for SalecSeIUHqerMpJ

9 5/8 non rotation Bottom and top cementing terial: rubber material is Buna-N rubber, polyurethane material.2.Application Environment: Buna-N rubber is used for well cementation when the temperature of down hole is lower than 120 centigrade. Although Polyurethane material has higher-temperature resistance than Buna-N rubber, Buna-N rubber has better flexibility and wear-resistance than Polyurethane. Thus, Buna-N rubber is adopted in big oil oduct features: The bore diameter meets professional standard and has no influence on pump pressure. The drillable aluminum alloy is  is much better than plastics or glass fiber reinforced plastics. It reduces drilling time and provides the cement plug enough braced force while cement plug is descending in casing.4. Feature1).Top cementing plug & Bottom cementing plug.2).Common & non -rotary type3).High temperature and high pressure resistance5.Technical Specification and ParameterSize   of CasingO.D.Overall   LengthType5-1/32"Rotar/4"   or/32"Non-Rotar/64" fAmqGKWv5auT It is mainly suitable for drilling wells, agricultural irrigation wells, geothermal air conditioning holes and other well holes,It is especially suitable for water intake projects in mountainous and rocky strata. The efficiency is more than ten times higher than that of the traditional rotary drilling rig, and the economic benefit created for the user is very considerable.
