After nearly a year's research, technicians of Zhongyuan Oilfield No.2 Plant Technology Institute successfully developed the KYB-I electric submersible pump clear salt valve device to solve the problem of electric pump well-being and salt prevention. Up to now, the implementation of the device, the average salt-free 20-port salt pump-free extended period of 100 days.
Conventional electric pump well doping salt method, prone to two conditions: First, large displacement of water so that casing gas compression down into the pump , causing air lock and underload stop, and second, large displacement of water led to Large particles of undissolved salt off into the pump, stuck high-speed operation of the electric submersible pump impeller, resulting in an instant high current, causing overload stop and downhole unit burning. In view of the above problems, the technicians of the technology electric pump room start the technical research and innovative ideas to develop the KYB-I electric submersible pump clear salt valve. The device utilizes the principle of natural gravity separation by different fluids, Circular space bi-directional fluid movement relative to the organic combination of the oil can be formed annular space gas and liquid flow, while the flow of water can be controlled to prevent large particles of crystalline salt off, casing compressed into the pump, so as to avoid the electric submersible pump In the process of clearing salt all the anomalies. Break through the long-term troubled pump anti-salt technology bottlenecks.
From the second half of 2010 to the present, the Institute for Process Technology did not occur any wells and overhauls due to salt in one well after obtaining 32 well pump wells, Salt effect.
