Recently, from Tahe Oil Production Plant No.2 oil production team technical group was informed that since 2009, in the Tahe 12 area application of "non-stop pump" measuring the surface technology, the implementation of ESP wells measuring surface 109 wells, none Wells shut down due to abnormal liquid level phenomenon. It is understood that ESP submersible pumps are relatively fragile, and generally stop doping dilute liquid level for too long may cause heavy oil into the pump, and then abnormal shutdown. Tahe Oilfield under the jurisdiction of the production of the second team of technical staff, after the oil well production dynamic observation and analysis of research, according to the different oil supply situation, the wells are divided into two types of liquid level monitoring, adequate liquid supply, high liquid production , The output remained stable, the first stop informing station doping, and then stop monitoring pump quickly, measuring the end of the sparse recovery, completed within 30 minutes; for the poor supply, the measured liquid production decreased significantly, the pump operating current In the vicinity of the underexposure value, due to the low dilution column height, dredging dilute 30 minutes may lead to heavy oil into the pump, the general use of abnormal wells to stop the opportunity to implement the static liquid level, the real-time take the shut-in recovery or water refill energy. Since 2009, there have been 109 wells on the electro-submersible pump surface and none of the wells shut down abnormally due to the liquid level being measured, thus improving the production efficiency.
