Two wells in the shallow basin of Illinois, Ill., That were drilled with conventional rod pumps, frequently pump down due to severe corrosion and scale formation, resulting in reduced production and increased operating costs that halted production. Since the gas lift pump minimizes the potential for fouling, corrosion and wear, Team January has taken the gas-lift service multinational gas lift pump instead of a rod pump for oil recovery operations since January 2004 and has achieved success. Air lift system is through the compressed gas (made of plastic and stainless steel device) filled with the discharge method of alternating liquid flow to achieve lifting. The gas lift pump is a well-fluid lift system consisting of interconnected chambers. Flow in the natural gas and air carried in the alternating chamber of the two pipes in the rise (Figure a). The working medium can be compressed natural gas or air, two test wells with air. Closed design ensures no air leakage in the wellbore. The console first applies compressed air at a pre-determined pressure of 1,034 kPa to the top of the odd-numbered cavity via an internal control line and at the same time discharges the pressure in the even-numbered cavity through another internal control line (Figure b). The pressurized gas in the odd cavity displaces the flow to the upper even cavity, and the check valve prevents the flow from flowing downwards. The console then applies pressurized air to the top of the even cavity while simultaneously venting the pressure in the odd cavity to move the flow in the even cavity to the odd cavity in the upper cavity (c). After the lowermost fluid cavity is emptied and the pressure is released, the fluid flow will flow into the cavity due to gravity and the process will be repeated. The liquid inlet and bottom liquid flow chambers must be kept below the well's liquid level. The liquid arriving at the surface flows into the production facility (figure d). The number of cycles and pump displacement are variable and depend on the depth of the well, the degree of recoverability of the reservoir, the hydrostatic and dynamic levels, the specific gravity of the liquid, the oil content, the suspended solids, the temperature and other factors. Air lift system operating depth of up to 701 meters. At depths less than 305 meters, the actual daily output is as high as 28 tons. Design requirements of the material used bottomhole temperature should reach more than 76.8 ℃. For wells at a depth of 305 m, standard equipment requires that the compressed natural gas and air flow rates should be 0.85 to 1.42 m³ / min. Mieure13 well with the rod pump mining within a month rod, pipe, pump failure at the same time, operating costs hit a record high. The well has been working well since it was switched to gas lift pumping in January 2004. Hardacre5 wells operating costs ranks second in the company, in 2002 to check the pump 5 times in 2003, 6 times to check the pump, and then shut the well. The well in January 2004 into the gas pump, the use of improved gas lift oil recovery system has been working stability. By July 2005, about 15 months after the removal of corrosion, only a little more obvious corrosion or wear. At present, Team Company has carried out more than 20 months of gas lift oil field test. Team General Manager Dennis Schwarger said the gas-lift pump has been successfully tested in both applications for increased cash flow due to savings in costs and increased production. The world's first gas lift pump was successfully developed by John Mavi in ​​1995 and applied to North Indiana field in the United States. In 2003, the gas-lift pump was put into commercial application. At present, 16 gas-lift equipment have been installed in 5 U.S. states. Air lift system decentralized depth of 305 to 701 meters, Nissan liquid 0.14 ~ 15.26 tons. When the gas lift pump is used in a gas well, the engine fuel is extracted only from the produced liquid flow, and the gas compressor is driven by the produced gas from the well. In addition, the use of gas lift pumps on the Ohio River beach can be designed to be water flooded, thus significantly reducing the impact on the environment.
A laboratory vortex mixer is a device used in laboratories to mix small volumes of liquids or suspensions. It consists of a motor-driven platform that vibrates rapidly, creating a vortex in a test tube or other container. The vortex action causes the liquid to mix thoroughly and quickly. Vortex mixers are commonly used in biology, chemistry, and medical labs for tasks such as mixing reagents, suspending cells, and dissolving powders. They are often compact and portable, making them convenient for use in a variety of settings. Some models may also include adjustable speed settings and interchangeable attachments for different types of containers.
We have Mini vortex mixer,Multi-tube vortex mixer,Multi-module vortex mixer etc.
