The most common method of artificial lift pumping screw is the world, and the most common problem is that the pump operation is not completely filled, resulting in low productivity, because the pump is not completely filled capacity of the pump is greater than the yield or the air suction port of the pump wells Poor separation, part of the pump displacement by gas interference and loss, if the elimination of gas pump interference and control the pump running time, the pump displacement and the amount of liquid into the bottom hole to match, you can increase efficiency and reduce costs. Maintain the high yield of screw pump pumping practice as follows: 1, should be sonic liquid level determination to determine the relative depth of liquid production and pump suction inlet. If the liquid level is higher than the pump inlet, then the well can not be mined at maximum capacity. If the air interference affects the yield, the liquid level is higher than the pump inlet; if the excess pumping leads to low output, the liquid level should be at or near the pump inlet. 2, the dynamometer measurement pump full coefficient percentage, the application of integrated data acquisition system can simultaneously obtain the motor power and show data. One of the main uses of a dynamometer is to diagnose how the pump is operating and to analyze downhole problems. Applying production level measurements in conjunction with a visualization diagram can tell if the well is producing at maximum throughput, whether the column height is above the pump suction depth, whether the pump is not completely full, and whether the free gas is moving up the annulus. 3, diagnosis of low energy efficiency wells. The diagnostic method is to determine the total efficiency of the pumping system, and to determine the total efficiency, only the power input to the prime mover, the production pressure at the bottom of the well, and the exact production test data are determined. The general beam pumping system, the total efficiency should be about 50%, if lower than this should improve its performance. Technologies that increase overall efficiency include maintaining high volumetric efficiency (pump size matches wellbore injection volume, eliminating gas interference, pumping with an evacuation controller or timer ) and replacing an oversized motor. 4, underground gas separation. Invalid pump operation is often caused by air interference, which can be diagnosed by acoustic wave measurement and dynamometer. It is best to place the pump suction below the fluid inlet section and, if placed above, a gas separator. If the seat short section is arranged at least 10 ft below the bottom of the fluid entry section, effective gas separation can occur in the annulus, where the casing acts as the outer cylinder of the separator. However, well conditions often do not allow the pump to be placed below the fluid inlet layer, consider using downhole gas separators. Conventional air separators consist of a fluid inlet section (such as a perforated section), an outer cylinder (such as a fuel pipe with a plug on the bottom) and a diptube at the bottom of the pump. 5, controls the pump displacement can be controlled by adjusting the four kinds of parameters: Column feeler inches, the stroke length of the pump stroke rates, daily operating time. Due to the high cost of equipment, usually not to replace the wrong size pump. The easiest way is to change the configuration of the ground equipment, such as moving the beam to change the length of the ground and pump stroke; followed by the replacement of the motor pulley to control the pump number. Matching pump volumes with well productivity can be done by changing the daily run time. There are several devices that can be used to control run times: empty control, interval timer, and percentage timer. The air pump controller will stop the pump if it detects that the pump is not fully charged. Timer control pump running time, cheaper and easy to operate. The duration of the pump stoppage should be as short as up to 10% of the reservoir pressure rise in the bottom hole production pressure. Operators can use the above 45min for each well for the sonic, dynamometer and other measurements to determine well productivity, downhole pump dynamics, downhole gas separator dynamics, sucker rod and beam pumping load, motor dynamics. Through 45min analysis, the operator can maximize well production, reduce operating costs.
