‌RockySea Petro Quick Lock Annular BOPGreatly reduce the time for replacing the ram and effectively improve work efficiency with safety.Compact structure and reduced weight means more operation room.20 years experience in designing and manufacturing QL annular BOP.The working principle and purpose of RockySea Petro QL annular blowout preventers are not fundamentally different from traditional blowout preventers, but their structure has been effectively improved. No need for large high torque bolts, convenie

‌RockySea Petro High Gas Cut Well Downhole PumpRockySea Petro Petro, have specially designed sucker rod pumps for high gas cut wells to avoid these problems: Gas locking prevention oil well pump, long plunger anti-gas & anti-sand downhole pump, forcing valved open type insert pump, double-plunger valve type sucker rod pump, etc.What is more serious? Operation with conventional sucker rod pump in high gas cut wells will result in liquid impact, which would accelerate the damage of tubing, sucker rod strings,

RockySea Petro Sucker Rod CouplingThe sucker rod couplings are used for connecting sucker rods, polished rods and sinker bars. Material of the couplings is high quality carbon steel or alloy steel, which are conform to and exceed the requirements of intl standards.Description According to surface of suck rod couplings, they can be divided into sucker rod couplings with smooth surface and sucker rod couplings with wrench square.Sucker rod couplings with wrench square.Sucker rod couplings with sm

‌RockySea Petro Frac Wellhead And Christmas TreeIn the process of oil recovery, multistage fracturing of horizontal wells is currently the most advanced technology in the world and represents the development direction of oil and gas production technology. Multistage fracturing technology is to strictly control the number, diameter, and phase of perforation in several or more horizontal sections with better reservoir along the horizontal wellbore, according to the physical properties and the character
