It is reported that the Gasi E31 Reservoir's reduced-oxygen air-flooding gas injection station has passed the preliminary trial operation and is now officially put into operation. This is also the first oxygen-reduced gas injection station in Qinghai Oilfield.
Gaskule Oilfield is a hidden structure No. 1 discovered by seismic exploration in 1958. It was later renamed "Gaskule" and is still in use today.
According to reports, as the unit with the longest exploitation time in Qinghai Oilfield, stable production of old oil reservoirs has become the top priority for the plant to complete its annual production tasks. Due to the water drive development method of E31 reservoir in Gasi Oilfield, it has been unable to meet the demand for stable production. For this reason, Qinghai Oilfield No. 1 Oil Production Plant selected the main part of Gasi Oilfield E31 reservoir structure to carry out a reduced oxygen air gravity drive test project-the existing air is filtered and oxygen is injected into the ground, which effectively supplements the formation pressure and improves oil well recovery. The tertiary oil recovery technology.
From the preliminary design of the project, the preparation of reservoir development prospects and geological data, to the gradual improvement of supporting facilities on the ground, it took two years to build the first oxygen-reducing gas injection station in Qinghai Oilfield.
The Gasi E31 reservoir oxygen-reduced air flooding gas injection station uses the central control platform as the "brain" to coordinate and coordinate the technical routes of the two major systems of gas injection and oil and gas gathering and transportation, and form a joint organization with 28 oil wells and 6 gas injection wells under its jurisdiction , Centralized management mode, equipped with SCADA system, programmable logic controller PLC and other systems, not only can feed back important process node parameters, wellhead data and other production information in real time, but also display alarms and remotely control historical trends.
Qinghai Oilfield stated that the establishment of the gas injection station is an important node in geological development. The development geological studio of the first oil production plant will continue to follow up on data feedback to ensure that the project results are established and advanced.
Qinghai Oilfield is the highest oil and gas field in the world and one of the earliest oil fields developed in China. The Qaidam Basin, located in Haixi Prefecture, Qinghai Province, is an important oil production and gas supply base in the four provinces of Qinghai, Tibet, Gansu and Ningxia, with an average elevation of about 3000 meters.
