| The world's most General Mechanical methods is a | | | | control or timer control with pumping) and replace |
| screw pump of pumping oil, and its most common | | | | the motor too much. |
| problem is the pump operation can not be | | | | 4, downhole gas separator. Invalid gas pump is |
| completely filled, resulting in low productivity, the | | | | often running interference caused by sound level |
| pump is not completely filled due to the well pump | | | | measurement and dynamometer for diagnosis. |
| output capacity greater than or not pump gas | | | | Would be better to put fluid into the pump inlet |
| separator at the entrance Well, part of the pump | | | | below the layers, placed at the top should be |
| displacement bullied interference loss, if the gas | | | | used if the gas separator. If a short section of |
| pump to eliminate the interference and control of | | | | the valve seat arranged in layers of fluid into the |
| pump operation time, the pump displacement and | | | | bottom of the following at least 10ft, air can |
| the amount of fluid into the bottom hole match, | | | | occur in the ring effective gas separation, this |
| you can improve efficiency and reduce costs. To | | | | time from the separator casing outside the tube |

| approaches are as follows: | | | | wells to pump fluid into the layer below the place, |
| 1, surface acoustic wave should be conducted | | | | then consider the use of downhole gas separator. |
| to determine the yield surface and the relative | | | | Conventional gas separator by the fluid into the |
| depth of the pump intake. If the liquid level above | | | | part (such as perforation short section), outside |
| the pump intake, it is impossible to maximum yield | | | | the tube (such as the bottom plug of a pipeline), |
| of extraction wells. If the interference effect gas | | | | and pump at the bottom of sealing liquid tubes. |
| production rate, the liquid level above the pump | | | | 5, control the pump displacement can be carried |

| surface should be pumping at or near the | | | | parameters: plunger size, stroke length, the |
| entrance. | | | | number of red pumps, a daily operating time. |
| 2, Indicator Measurement of the pump is full of | | | | Since the cost of equipment due to large, usually |
| coefficient of percentage of integrated data | | | | do not replace the wrong size pump. The easiest |
| acquisition system can be applied to both motor | | | | way is to change the configuration of the ground |
| power and indicator data. Indicator diagram of one | | | | equipment, such as mobile beam to change the |
| of the purposes is to diagnose the main pump is | | | | ground rod and pump stroke length; followed by |
| running and analysis of how the problem | | | | replacing the pump motor pulley to control the |

| production wells, liquid column height is higher than | | | | used to control the running time: air pumping |

| 3, diagnosis of inefficient wells. Method of diagnosis | | | | pump operation time, less expensive and easy to |
