RockySea Petro Float Collar and FloatData sheetAdvantageRockySea has extensive experience in manufacturing float hoops and shoes, and its products have the following advantages.1) The reliable valve body structure reduces the resistance of cement slurry flow.2) All internal accessories are drillable and have the same diameter as the casing.3) The special structural design effectively prevents the backflow of cement slurry.4) The buckle can be processed into BTC/LTC/STC/VAM/FOX/TP-CQ/OTTM accordi
VIEW DETAILSRockySea Petro Coated Sucker RodWith the increase of working time, conventional sucker rods are prone to corrosion and eccentric wear during operation, and are not suitable for harsh working conditions. In 2012, RockySea Petro developed a fully coated sucker rod. By using HDPE resin to fully coat the sucker rod body, the anti-corrosion and anti-abrasion of the sucker rod is realized. And this tech of RockySea Petro has gained patent in China, Canada and the United States.Description It is the ideal matching

VIEW DETAILSRockySea Petro Spiral Drill CollarIn directional drilling, due to the large deviated well and the large contact area between the drill collar and the borehole wall, problems like sticking and jamming are more likely to happen. The spiral drill collar reduces the contact area between the drill collar and the borehole wall, so it is widely used. Spiral drill collars are not listed in intl standards, but due to its practical value, many manufacturers have produced them.Description The function of
