United States Dyna Pump Co., Ltd. developed a new pump
September 12, 2023
A new pump, Dynalow, developed by Dyna Pump Inc. of the United States, is a low profile pump that has the same features and functionality as the company's previous DynaSave pump. Its fixed height of less than 3 meters, the maximum stroke of about 1 meter. The pump is designed for use in farm irrigation systems and weighs less than 635 kg for safe operation. Calculating the pump wellhead pressure with the downhole dynamometer The pump controller has evolved into a full-time power meter. Currently, computers used in mines can accurately measure load, position, and pressure, temperature and capacity. As a function of position, this technical improvement requires accurate plane load measurement. Oil well automation managers in Houston, U.S.A can not only calculate the dynamometer for each stroke of the downhole pump accurately, but also calculate the wellhead pressure of the pump. The starting point for managing flow areas and pressure support is quite important. The data entered by the dynamometer includes the fluid load, the total stroke, the net stroke and the movement of the tubing. Fluid Loading The drawing chosen is different in the upper and lower load lines on the dynamometer. Fluid loads can not include friction and inertia of the fluid. Ideally, due to the same buoyancy, the load line must be lowered below zero load. The accuracy of buoyancy calculations depends on accurate load measurement, design parameters of the sucker rod, and inclination of the tubing fluid (gradient). Through the entire input data, pump inlet pressure can be calculated. During the calculation, other required information can also be displayed. Replacing Sucker Rods with Cables A new oil well pump system that replaces sucker rods with cables is being developed and tested by Taylor Pumps, Inc. of Texas, USA. The system uses steel cables instead of sucker rods and ground tower lifting devices to replace the oil pumping racks. The pump lift attached to the cable is computer controlled. A new tool to reduce airlocks and pumps has been developed and tested and patented. Under the new drainage tool into the bottom of the pump, tubing can be drained when needed. The newly developed two tools are used for tubing anchor (suspension) displacement and chemical measurement points. The new tool can increase production of crude oil with less impulse and longer stroke per minute, producing 24-hour airless lock, using computerized control of the system to keep the surface of the annulus liquid optimized. This control can be replaced by lifting pressure instead of tension , Real-time measurement, and each stroke can send instructions to the computer. The economic value of new tools is recognized when repaired. This special cable is rolled up, the downhole pump assembly is repaired, and then it is returned to the bottom of the well without the need for workover equipment. The pumping method for this tool is in the early stages of testing and will be applied to the field in the near future.
