    Coated Sucker Rod

    RockySea 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

RockySea Produced-Water Oilfield Steam Generator


  • Including high-dryness Oilfield steam generator, supercritical one-through steam generator, oilfield produced water oilfield heat boiler, all-polished rod oilfield steam injection boiler, desulfurization and denitrification steam injection boiler.
  • According to the different requirements of customers, energy-saving, ultra-high pressure and environmental protection boiler types are designed.
  • RockySea Petro has developed new series of mobile on-board and skid-mounted steam injection boilers with evaporation of 9.2~30t/h and working pressure of 17.2~26MPa.
RockySea Petro has been developing the leading product of oilfield steam injection boiler (wet steam generator) since 2011 and has acquired the qualification of Class A1 boiler manufacturing in 2012. At present, the annual production capacity is 50 sets.


Description

Produced water refers to the water produced with crude oil from oil wells. The produced water usually contains oil, salt, mechanical impurities, dissolved oxygen and saprophytic bacteria and so on, causing pollution to oilfields and the surrounding environment. After treatment, it can be refilled into the oil layer or used as the water source of the gas injection boiler. Water Treatment System According to customer requirements, SanJack adopts advanced water treatment technology and successfully develops Produced-water Oilfield Steam Boiler using produced-water as water source.



We have designed the air float oil removal unit to remove oil in produced water in the water treatment device of the oilfield produced-water boiler. Then replace the strong acid removal resin with weak acid resin and increase the treatment stage to eliminate hardness; afterward, the qualified boiler for produced water treatment is supplied with water through ultrafiltration and reverse osmosis.

Water Quality Comparison of Produced Water Steam Injection Boiler



The comparison between the above two tables shows that the requirement for raw water is greatly relaxed by produced water treatment. Except for PH value, each index is relaxed 4 times to 2000 times. More than 60% of produced water produced in oil field is within the scope of treatment and reuse. Through design improvement of boiler, the index for steam injection water production is also slightly relaxed under the premise of ensuring safe operation of boiler.

Steam Injection Boiler System

Produced Water Steam Injection Boiler mainly add suspended matter separation device, energy recovery system and convection section monitoring system. By checking the temperature changes, judge the scaling condition of furnace pipe and eliminate the hazards in time. Improve boiler’s suitability for produced water:

  • Centralize condensate in flushable and replaceable parts. Sedimentation is suitable for produced water operation.
  • Increase inlet water temperature and exceed dew point temperature of flue gas, so as to avoid condensation of water vapor in flue gas on finned tube in convection section and cause low temperature corrosion of pipe;
  • Separate suspended matter generated with high temperature, avoid corrosion and scouring under scale, and increase heat recovery;
