The mixing optimization technology for large tanks mixed with thin oil in Northwest Oilfield significantly reduces costs

SINOPEC News Network News Since the beginning of the year, the Petroleum Engineering Technology Research Institute of Northwest Oilfield Branch has implemented the optimization technology of mixing thin oil large tanks to simplify the process flow, reduce labor intensity, greatly improve the level of automated production, and greatly simplify production operations.
The construction cost has been reduced by 12 million, and the annual electricity consumption is expected to be saved by 1,796,600 kWh
.

In Tahe Oilfield heavy oil and ultra-heavy oil production, the mixing technology of large tanks mixed with thin oil plays a vital role in ensuring the stable and higher production of the oilfield, but some problems gradually appear during operation.
The system has reached a bottleneck.
The investment in the new thin oil mixing tank is relatively high.
The thin oil mixing tank mixing process is long, occupies a lot of equipment, and the energy consumption of the thin oil mixing tank is high.
Thin oil needs to be lifted into the mixing tank for mixing
.

Researchers analyze the properties of heavy oil and thin oil products, determine the optimal blending ratio range through experiments, and determine the online blending control blending precision.
For Erlian heavy oil and thin oil from the first plant, Erlian heavy oil and Shunbei The condensate oil is mixed according to different proportions to obtain thin oil blended with different densities.
The blended thin oil and heavy oil are mixed and the dot diffusion test is performed to determine the optimal blending ratio of thick oil and thin oil
.

By optimizing the mixing of large tanks into pipeline mixing, the researchers meet the increasing demand for thin oil mixing, and at the same time release the storage tanks occupied by the second unit, reduce the processing system load, save energy consumption, and reduce labor load
