The oil and water well pumping rate of the 8th Daqing Oil Production Plant decreased by more than 30 percentage points over the past 12 years, from 47.6% in 2001 to 14.9% in 2013. The average pump inspection period was 805 days and the longest period was over 1800 days. The continuous decrease in the rate of pump inspection has ensured that the output of crude oil produced by the Eight Oil Plants has been rising year after year.
Reducing the rate of pump inspection in oil wells and prolonging the period of pump inspection are the basic measures for improving production. In recent years, the Eight Oil Production Plants have continued to strengthen the fine management, increase the related technology for the middle and deep oil wells in the surrounding oilfields, and scale the application.
Wu Gang, director of the engineering technology brigade of the plant, took the example of the Yifang 481-1 well. This well has not been inspected for 60 months. The inspection period is 5 years, saving production and maintenance costs of more than 60,000 yuan, and the operating rate is high. Crude oil production is guaranteed."
The oil area under the jurisdiction of the No. 8 Oil Production Plant has the characteristics of deep well and poor physical properties of crude oil. If the pump fails, the oil well cannot be normally recovered, and it is necessary to check the pump. According to reports, the pump is connected to the sucker rod and the pumping tube, and the downhole working environment is very poor, which can easily cause the breakage of the rod and the tube, the loss of the tube, and the loss of the pump, namely “double break†and “double leakâ€.
In response to these two problems, the technicians analyzed the weak points of the bar system, improved and strengthened it, reduced the occurrence of bar broken operation wells, optimized the bar uprighting technology, reduced the eccentric wear of bars and pipes, and applied the combination tubing technology and tubing anchors. Definite technology has improved the safety level of the pipe string, improved the working status, and reduced the occurrence of pipe breaking operation wells. At the same time, they strengthened the ball and seat hardness testing of Verr, promoted the use of solid wax guards and scale inhibitors, and formed a distinctive “double-break†and “double-leakage†treatment technology for peripheral low-yielding medium and deep oil wells.
Management is the guarantee of the implementation of technical measures. This plant implements objective management of oil wells, disaggregates indicators, defines the responsibilities of the management department, engineering technology team, oil mining and team, and implements the entire process tracking of the team management personnel during the operation process. The plant and technical departments manage Random checks of personnel to ensure the quality of construction work.
In addition, the eighth oil production plant has implemented the entire process supervision system for the wells, reducing the overall rate of rework. When compiling the work plan, the process string and construction process should be optimized, and the downhole tools should be strictly accepted into the factory and issued.
Semi Precious Stone
HR STONE mined
two kinds of semi precious stones: blue sodalite and tiger eye. Specially sodalite mineral quarry in Africa, The sodalite rock in Africa that also
contains abundant blue
sodalite and white nepheline. Both of these minerals have a hardness of approximately 6
on the Mohs hardness scale.The quarry start to yield two kinds of sodalite Blue blocks, big size blocks, small size blocks in 2018. Max size of big block can be about 250*180cm
and weight about 15-20 ton per block. Small block has two sizes: 3-10cm 10-30cm
. Annual yield of blocks is about
100containers.Blue sodalite has two kinds of color classifications, one is blue mainly,
one is blue and white mixed.According to the color purity and texture,
the blocks have different ranks for your reference.
We ship the blocks to China and produce
them into finished products, such as translucent blue sodalite slabs, table and
arts. Whether super blue color or blue and white mixed, you can find out the
right color you favor from our blue sodalite blocks and finished product.
We normally produce translucent blue
sodalite slab with small blocks, so the blue sodalite is laminated with natural
or artificial stone, glass, or Acrylic.
If you prefer blue sodalite slab is translucent,
you can chose slab laminated with glass. Translucent blue sodalite is full
of bright and fantastic colors and
atmosphere.
Blue sodalite blocks, small or big size; blue sapphier stone slab, blue
sodalite table-,welcome to contact us for details.
sodalite
vs lapis :Blue sodalite has a strong
resemblance to Lapis. For metaphysical purposes, this stone is said to improve
one's Logical thinking.
Sodalite was originally
discovered in Greenland in the early 1800's, then about 100 years later it was
next found in Ontario. A few other sources, mostly in Africa, exist today.
We also have other semi precious
stones wholesale, such as Tiger eye rough-super yellow color and commercial rank
for your choice. Tiger eye only has small blocks.
