Oilfield pumping pump pumping efficiency impact factor analysis
The impact of natural conditions on the pumping efficiency of pumping pumps
In the process of oil extraction, the impact of the natural environment can not be ignored, according to the differences in the natural conditions of oil extraction must be selected accordingly pumping pumps, in order to maximize the efficiency of oil extraction.
This shows that the same pumping pumps in different natural environments under the pumping efficiency is there is a certain difference between the natural conditions for the pumping efficiency has a significant impact, mainly reflected in the following aspects:
- the geological conditions for the pumping pump pump effect. If the geological environment of oil storage is loose cemented sandstone, or due to long-term water injection in the process of oilfield development, gas injection to the reservoir skeleton brings great breakage, which leads to the production of oil wells out of sand conditions. Once the oil well out of sand, sand will be on the Vanier seat, bushings, Vanier ball and piston pumping pump components such as threat, so that the relevant parts of the great wear and tear, so that the pump efficiency is greatly reduced.
- the gas to the pumping pump pump efficiency to bring the adverse effects. Gas for the pumping pump pumping efficiency of the impact is mainly reflected in two aspects: on the one hand, if the oil field reservoir in the lower energy, insufficient liquid supply, or wells contain more gas, once the pump inlet pressure than the saturation pressure is small will lead to oil and gas mixtures into the pump. The mixed gas is the volume of oil is reduced, the pump efficiency naturally decreases. On the other hand, when the piston is in the lower dead center, if the gap between the swimming and fixed vaner has the existence of high-pressure oil and gas mixtures, in the process of the piston upward oil and gas mixtures will be expanded and thus lead to fixed vaner can not be opened in time so that the pumping pump pumping efficiency is reduced.
- the oilfield wax content and temperature for the pumping efficiency. Oilfield has a certain amount of wax, when the temperature drops to the wax precipitation point there will be wax precipitation, thus affecting the pumping efficiency, pumping pump pump efficiency decline.
Influence of equipment factors on pumping efficiency
Suction pump is a professional equipment in oil extraction, the quality of the pump itself has a direct relationship with the pump efficiency.
In the market, the production and manufacture of pumping pumps manufacturers, different manufacturers of pumping pumps of varying quality, pumping efficiency there is not a small difference.
Some manufacturers in order to reduce production costs, in the production process, such as the choice of raw materials to make sacrifices, so that the quality of the pumping pump has declined.
In the operation process of various parts of the wear and aging fast thus affecting the pump efficiency.
In addition, in the pumping pump operation process certain parameters will also affect the pump efficiency.
First, the stroke loss caused by the pumping pump pump efficiency reduction.
In the process of pumping machine operation, the oil pipe and pumping rod column is subjected to alternating loads, causing elastic expansion and contraction and thus bring stroke loss.
The stroke loss of the oil pipe and the stroke loss of the pumping rod are the two main types of stroke loss.
Large pumping depth is the most important factor affecting stroke loss. Secondly, pumping pump leakage leads to a reduction in volumetric efficiency, which in turn causes a decrease in pumping efficiency.
Discharge part and suction part are the two main types of pumping pump leakage, the ring gap leakage of the liner and plunger clearance is the main discharge part of the leakage, while the leakage of fixed valve is the main suction part of the leakage.
The main causes of pumping pump leakage include the large well slope at the lower pump and the deep moving liquid surface.
Countermeasures to improve pumping efficiency of oilfield pumping pumps
- strengthen the geological survey work. Geological conditions is an important factor affecting the pumping pump pumping efficiency, so in the early stage must strengthen the geological survey work, in order to avoid as far as possible unfavorable natural environment for the impact of oil extraction, to ensure that the pumping pump work efficiently, improve the efficiency of oil extraction. In the process of geological survey, surveyors must be mining site geological conditions for in-depth investigation, a comprehensive grasp of the oil layer in the sand, gas content and water content, so that in the process of oil extraction can take effective measures to cope with the prevention of oil wells out of the sand and other pumping pumps will have an adverse effect on the pumping efficiency of the problem of the generation of the natural environment for the pumping efficiency of the effect of the minimization.
2.the construction of pumping pump operation system. In the pumping pump operation process, human factors for pumping efficiency has a significant impact, so it is necessary to establish a scientific operation system. Thus, the operation of the staff to standardize the workflow and link management, the establishment of a scientific maintenance and conservation system to protect the efficient operation of the pump.
- improve the overall quality of staff. High-quality staff for the pumping pump operation process has a positive effect on the improvement of pumping efficiency, which must be through the training system to make the staff skills and knowledge to be updated and upgraded.
- In the training process to teach the staff the principle and operation of the pumping pump, the relevant knowledge of oil extraction. And for the latest pumping equipment to teach the staff of the new equipment related knowledge.
