Hydrocarbons production installation and method |
摘要 |
Some embodiments include a heavy-oil-based hydrocarbons effluent production installation for the production of hydrocarbons from at least one well. The installation includes an effluent-lightening fluid injection system at the bottom of the well, an effluent-evacuation pump, a plurality of sensors that measure physical units relating to the installation, and an automated device suitable for optimizing the lightening-fluid injection flow-rate and for regulating the pump speed. The automated device regulates the pump speed according to the physical units and a predetermined target production value. The speed of the pump and the physical units are within a predetermined range of values. some embodiments include a hydrocarbons production method in such an installation. Some embodiments make it possible to ensure a minimum consumption of lightening fluid, while ensuring good operation of the pump and good productivity of the well. |

1. A heavy-oil-based hydrocarbons effluent production installation for a production of hydrocarbons from at least one well, the installation comprising:
an effluent-lightening fluid injection system at a bottom of the well; an effluent-evacuation pump; a plurality of sensors for measuring physical units relating to the installation; and an automated device for optimizing a lightening-fluid injection flow-rate and for regulating a speed of the pump, according to the physical units and a predetermined target production value, the pump speed and the physical units each within a predetermined range of values, wherein the lightening-fluid injection flow-rate is proportional to a gravity index of the effluent, the automated device performing a real-time calculation of the gravity index of the effluent, wherein one of the sensors is a first pressure sensor located at a wellhead and another sensor is a second pressure sensor located at a discharge of the pump, wherein the automated device is further for calculating a gravity index of the effluent according to data provided by said first and second pressure sensors.
