China Petrochemical News Network reported that the Gudong GOGD9-8 well, which had been "sleeping" for 4 years, was "awakened"
.
On August 26, the report of the oil production management zone 4 of the Gudong Oil Production Plant in Shengli Oilfield showed that the well produced 5 tons of oil per day.
Well resume work has greater confidence
.
The management area is dominated by heavy oil development.
The number of long-stop wells and low-yield and low-efficiency wells has been increasing due to comprehensive factors such as high rounds of throughput decline, edge and bottom water intrusion, and increasing number of variable wells each year, resulting in controlled reserves loss and production.
Decrease big
.
How to wake up the "sleeping" oil and water wells from their dreams and maximize the production potential is the direction that the technical staff of the management area has been seeking
.
"In order to turn a long-stop well into a profitable well, it is important to tap the potential of the well
.
" At the beginning of this year, they focused on the breakthrough of oil and gas resources, made detailed management, and conducted in-depth analysis on reservoir conditions, wellbore conditions, and water injection management, established long-stop wells "household registration files", and conducted comprehensive studies on long-stop wells and low-yield wells.
In Gudong Re 5 and 9 wells, through the conversion of water-to-oil wells, the daily oil increase was 4.
9 tons after resumption of production; in Gudong 281-4 wells, through large repair holes, the daily oil increase reached 6.
2 tons
.
Since the beginning of this year, the management area has carried out solid support for long-term shutdowns, tapping the potential of the old area to overcome difficulties, and established a shutdown well management project team composed of the backbone of the technical management office, the production command center, and the operation management office
.
They work from three aspects: formulating measures, production and operation, and business optimization, clearly dividing labor, assigning responsibilities to people, calculating the precise benefits before the measures, tracking the benefit evaluation after the measures, improving the rate of opening wells, and improving the effectiveness of the measures
Up to now, the management area has successfully brought 44 "sleeping wells" back to life, with a daily oil increase of 54 tons, a cumulative oil increase of more than 4,700 tons, and a profit of more than 3.
1 million yuan; the number of wells opened per day has increased from 407 to 439.
The utilization rate of oil and gas assets has increased substantially
