美国Diamond Scientific公司研发新型抽油井的油管内防砂防磨涂层(ACR-T16),用于延长油井的修井周期,降低采油成本。多年来,抽油机的抽油杆在油管内往复运动,极易造成磨损,往往6个月就需要进行抽油井的修井作业。井下储层的出砂,以及油流中的腐蚀性物质,如硫酸氢盐、甲烷和二氧化碳等,更加剧了磨损过程。科研人员历时5年开发了 Diamond Scientific Corporation of the United States has developed a new oil well sand control and abrasion resistant coating (ACR-T16) for prolonging the workover period and reducing the oil recovery cost. Over the years, the pumping rod pumping unit reciprocating motion in the tubing, easily lead to wear and tear, often six months on the need for well workover pumping wells. Sand production in the underground reservoir, and corrosive substances in the oil flow, such as hydrogen sulfate, methane and carbon dioxide, exacerbated the wear process.
