This year, the Guanghua Oil Production Management Zone of the Jianghan Oilfield Production Plant has aimed at crude oil production targets, focusing on the adjustment of one well, one well, one well, one well and one well.
Make a fuss about strategy and optimization of production parameters to ensure the safe, efficient and stable operation of oil wells
.
Adjust one well, one strategy to enhance the "immunity" of oil wells
"Oil wells are the same as people.
Careless management will cause headaches and brain fever or even lie down in the well.
Therefore, it is necessary to regularly'cleanse the intestines and detoxify' the oil wells and improve the immunity of the oil wells so that the oil wells can be less sick!" Xu Lei, a technician in the area, said with deep feelings.
.
The oil fields under the jurisdiction of this area have the characteristics of easy wax formation, easy salt formation, and easy sand production.
The oil wells are generally weak in "physique".
This is the main reason for the abnormality of the oil wells.
, Constantly explore the secrets of health
.
Through the formulation of “health-preserving prescriptions” and scientific adjustments of “one well, one strategy” according to well conditions, hot oil well washing is carried out for some oil wells with high production and severe wax deposition, and for oil wells with high liquid volume and shallow wax deposition.
Wide-slope 3-12 wells are prone to wax formation.
In addition, the wells are in poor condition and frequent pump leaks have caused the wells to lie down.
In the past year alone, three pump inspections were carried out, which made everyone's brains awkward
.
Therefore, after analyzing the well history and wax deposition depth of the well, the technician adjusted the previous hot oil well washing method to the braising method, and the repair-free period was extended from 3 months to 9 months
From 1-3 quarters, a total of 115 well-times of hot oil well washing, 71 well-times of simmering wells, 56 well-times of superconducting well washings, 14 well-times of well washing methods were adjusted, and 6 wells of wax removal and anti-paraffin agents were adjusted, effectively extending The production cycle of the oil well is improved, and the oil recovery time rate is improved
.
Optimize production parameters and improve the "essence" of oil wells
"Working parameters are a barometer reflecting the output status of oil wells, and they are very important in crude oil production
.
" Zhang Jiaguo, director of the technical information office of the area, said, "According to the different characteristics and dynamic changes of oil wells, rationally optimize production parameters and adjust the precision of oil wells.
Since the beginning of this year, the district has taken cost reduction and fee reduction as the goal, increased energy conservation and consumption reduction, and realized beneficial development
.
Through the dynamic monitoring and comparative analysis of the various parameters of the 166 production wells in the entire region, the current production status of the oil wells are sorted out one by one, and the benefit evaluation of a single well is carried out.
After the Haoxie 171 well was put into production last year, the energy gradually declined, and the fluid volume this year fell below 2 tons.
In June, the technicians replaced the well with a low-speed motor, reducing the number of strokes from 4 to 2.
9, and the output remained stable.
, The daily power consumption is reduced from 211 kWh to 124 kWh, the pump efficiency is increased by 11.
8%, and the power saving effect is obvious
.
The pump inspection operation of the Guang 4 Incline-7 Well was carried out on June 23 this year.
From the 1-3 quarters, the area reduced the stroke times by 37 well times, reduced the pump diameter by 9 times, increased the oil by liquid extraction 16 times, deepened the pump hook 7 times, adjusted the balance 19 times, and increased the daily oil by 7.
8 tons.
It saves 2187 degrees of electricity, and the comprehensive pump efficiency is increased by 0.
13%
