New applications of basic mechanics and chemistry will increase yields of low-yielding wells and multi-phase flow wells. Recently, two new positive displacement pumps were successfully developed by US researchers. The first is a spherical mechanical design with the largest Capacity and measurability of the displacement of its equivalent to more than its own dimensions and weight of 10 times the pump.And a unique balance of design makes the device work smoothly downhole.Other is driven by heat, is the physical characteristics of carbon dioxide Driven piston pump, which significantly reduces the operating costs of high-water-well wells for greater economic benefits due to reduced processing costs and, in the field of oil and other applications, the new pump has the potential to be exploited At present, both pumps have passed the field test and entered an early commercial development cycle, which can be ordered directly from the manufacturer or applied for a permit
The accuracy of the steel tape will directly affect the measurement accuracy, so the quality of the steel tape must be verified during use. At present, most metrology institutes are still using manual operation to complete the inspection of steel tapes. Use a microscope to compare the error of the measured steel tape with the standard steel tape on the steel tape long inspection platform. This method is automated, low in digitization, and labor-intensive. Big.
