Ultra-short radius horizontal well technology in Huabei oilfield to exploit the remaining oil at the far end
On September 19, the oil production plant No. 3 of Huabei Oilfield, which had been shut down for more than 4 years due to high water cut, opened the well with ultra-short radius horizontal well technology, and the daily oil production reached 11 tons, which has been stable for 48 consecutive days. In Huabei Oilfield, ultra-short radius horizontal well technology is used to excavat
What are the precautions for manual operation of electric valves
The electric actuator of valve is used to control the valve. If the valve cannot be opened and closed due to some factors, such as power failure, failure of the electric actuator, or is fixed in a certain position, it needs to be operated by hand wheel. So, what should we pay attention to when the valve actuator needs to be manually operated?
Matters needing atte
Pressure valve is a device used in hydraulic system to control and regulate liquid flow pressure.
Its working principle is based on the balance between the liquid pressure on the spool and the spring force. When the pressure in the hydraulic system exceeds the pressure set by the seat, the seat will be subjected to upward force, so that the disc is separated from the seat, and th
Because the seal plays a role in cutting and connecting, adjusting and distributing, separating and mixing media on the valve channel, the sealing surface is often subjected to medium corrosion, erosion, wear and easily damaged.
The reasons for the damage of sealing surface are man-made damage and natural damage. Artificial damage, is due to the design and manufacture not jing, m
Build green and low-carbon oil fields to be the pillar of green development
Reed ponds, rice fields, oil Wells criss-cross, Liaohe Oilfield Huanxiling oil production plant is located in the "wetland capital" reputation of Panjin. In the past six years, Liaohe Oilfield has actively organized the withdrawal of more than 900 square kilometers of protected areas, and invested a lot of funds to complete the shutdown and withdrawal of equipment and facilities
Method of preventing the regulator from getting stuck or blocked frequently
01, cleaning method
The welding slag, rust, and residue in the pipeline cause blockage or jam in the throttle orifice, guide part, and balance hole of the lower valve cover, resulting in strain and scratch on the spool surface and guide surface, and indentation on the sealing surface. This often occurs in the initial phase of operation after a new system is put into operation and
The green light scenery of Tarim oilfield is infinitely good
On May 21, Tarim Oilfield made full use of the natural advantages of the southern Xinjiang region located in the first and second solar radiation areas to strengthen the construction and operation and maintenance of new energy projects such as photovoltaic. At present, the photovoltaic power stations maintain the best state of full capacity grid-connected power generation, and th
Bayan Oilfield in North China drilled the deepest horizontal well in western Inner Mongolia
On May 14, Well Xinghua 1 Ping 5 in Bayan Oilfield of North China Oilfield was successfully drilled with a drilling depth of 6017 meters, a horizontal section length of 1032 meters, and a drilling cycle of 55.5 days, which broke the record of the deepest horizontal well and the shortest drilling cycle in the kilometer horizontal section of Bayan Oilfield and became the deepest hor
The new type of plugging agent independently developed in Northwest oilfield has increased oil significantly
Recently, the new liquid polysaccharide gel water blocking agent independently developed by Northwest Oilfield was applied in well TH12133 of Tahe Oilfield, the water cut was reduced from 97% to 41%, and the daily oil production increased significantly.
Northwest Oilfield has successfully developed a new type of liquid polysaccharide gel water blocking agent in view of the aggrav
Nitrogen gas is a common protective gas, mainly used in metal welding, cutting, smelting and other industries. Its principle is to use the inert and non-combustible characteristics of nitrogen to prevent oxygen and other gases from entering the gas environment, so as to achieve the purpose of protecting the metal.
The principle of nitrogen protection gas can be explained from th
52 measures to build a strong flood control dam in Tuha Oilfield
On May 15, at the northern foot of the Fire Mountain, Tuha Oilfield was constructing more than 700 meters of flood prevention levees, diversion DAMS and water crossing roads in the oil area to prevent snowmelt floods during high temperatures from affecting oil and gas production.
Tuha Oilfield is located in the eastern part of Xinjiang, the southern slope of the Tianshan Mountain
