Application of high water cut late phase stratified oil recovery technology in petroleum engineering

Difficulties in oil extraction operations

At the same time, after the mining of one geological structure block chain is completed, the work team needs to be adjusted in time, and after checking various performance indicators, the next geological structure block chain can be carefully and carefully mined. If you excavate in a hurry, it will often cause the slope protection to slip and cause injuries to workers working in oil and gas mining construction projects. In addition, the mining work should be carried out conservatively and timely inspections should be carried out after the mining of each geological structure to prevent natural gas leakage caused by careless mining, which may cause natural gas poisoning or even explosions, which will not only cause a large number of casualties, but also bring extreme social consequences influence.

Difficulties in supporting structure construction operations

In the construction of oil exploration engineering projects, the establishment of civil engineering support for the water injection layer must be carried out immediately after the oil extraction work is completed. Due to the complex underground environment and intricate geological structures, if the foundation pit support structure is not constructed to support the walls of the excavated injection layer, collapse and falling rocks will occur. In addition, due to the complex construction environment of oil and gas exploration and water injection layer construction projects, the relative air humidity, ambient temperature and stacking pressure are likely to affect the quality and basic shape of basic construction raw materials for civil construction. The quality of construction materials in the construction industry must also be strictly controlled to prevent the supporting parts from being insufficiently strong and causing instability during or after the construction process, resulting in collapse, burying people, or injuries caused by falling rocks.

Crude oil research and development is a large project with complex working conditions, high levels of technological risk factors, and cumbersome construction stages. In the later stages of scientific research and development of oil fields, high water content problems often arise. Once the oil and gas field separation cannot be improved, The quality of oilfields will eventually affect the expansion of oil exploration, and in turn increase the construction costs of oilfield projects. In the current development process, because the development of the industry has promoted scientific and technological innovation, the relevant scientific and technological progress in the development of oil and gas field science and technology has been gradually optimized and developed. The graded and classified oilfield production process can fundamentally solve the high water content in the development of oil and gas field technology, thereby improving the economic benefits of petroleum applications and completing the smooth promotion of petroleum construction projects. The oil and gas field is in the middle and late stages of the Dashui Oilfield, which increases the pressure on oil and gas gathering and transportation management of the oil and gas field. In order to ensure that oil and gas field production and manufacturing obtain more economic benefits, the rational utilization of crude oil processing technology development and design based on classification and classification can be seen. The economic benefits of classification and classification can be seen, and then the processing technology problems in oil and gas wells with high water content can be solved. Effectively promote the oil stabilization and water control technology and improve the economic benefits of oil and gas field production and mining.

Analysis of late stage characteristics of high water content in oil fields

Because the oil and gas field will also reduce the comprehensive production of the oil and gas field in the later stage, and the water content of the oil and gas field will gradually increase, thereby increasing the liquid production of the oil and gas field, and the transportation pressure of the oil and gas field will also be greater. At this stage, my country’s oil and gas fields have entered the stage of high-water-cut oil fields, which has increased the workload of oil and gas fields and increased the application costs of oil and gas fields.

During the research and development process of oil and gas fields, in the oil field period with high moisture content, industrial equipment must be scientifically used to carry out relevant work to ensure the standardized operation of the equipment to achieve dual guarantees of productivity and safety. At the same time, in the actual transportation process, it is necessary to separate the gas from the water in some stages. At this time, it is necessary to use certain industrial equipment to improve the design effect of the device, and to carry out balanced actual operations on crude oil production and transportation to prevent sudden accidents. The formation of the situation.

This is because crude oil will produce a large amount of wastewater during the process of crude oil extraction. During the process of crude oil transfer, the wastewater needs to be solved as a whole. Through a certain purification effect, a certain disposal result will be formed. At this time, a certain amount of wastewater must be applied. The filter device, through the overall use of the filter, removes the waste water in the crude oil, thereby forming a certain degreasing effect. It is necessary to meet the water quality irrigation regulations. After entering the irrigation system, the water pipe pressure needs to be used and the relevant operating steps of the water distribution well should be used to achieve a certain treatment effect.
