The FYK20DA series of pressure-controlled operation devices produced by our company is an important piece of equipment used in energy extraction fields such as oil and natural gas. It is mainly applied in pressure-controlled operation scenarios, that is, relevant operations are carried out when there is pressure at the wellhead. This can avoid damage to the formation caused by well-killing operations and enable safe and efficient extraction operations. Its specific application scenarios are as follows:
Well-servicing operations of oil and gas wells:
During the production process of oil and gas wells, equipment such as oil pipes and sucker rods may be damaged or malfunction, requiring well-servicing operations. By using the FYK20DA series of pressure-controlled operation devices, the pipe string can be tripped in and out without well-killing. This can prevent the contamination of oil and gas layers by well-killing fluids, protecting the original productivity of the oil and gas layers. This is particularly important for low - permeability and highly sensitive oil and gas layers. In some offshore oil and gas fields, well-servicing operations are costly. The pressure-controlled operation device reduces the use of well-killing fluids and subsequent treatment processes, significantly reducing well-servicing costs and operation time.
Well-completion operations:
When completing a well, it is necessary to lower the production pipe string into the well and carry out relevant operations. This device can accurately control the lowering depth and speed of the pipe string under the condition of pressure at the wellhead, ensuring that the pipe string is accurately positioned. At the same time, it maintains the stability of the wellbore pressure, preventing the uncontrolled ejection of formation fluids and ensuring the safety of operators and equipment. In the well-completion operations of deep and ultra-deep wells, due to high wellbore pressure and great operation difficulty, the pressure control and safety protection functions of the pressure-controlled operation device are even more crucial.
Implementation of production-enhancement measures:
After production-enhancement operations such as acidizing and fracturing, subsequent operations such as fluid drainage and production testing are required in a timely manner. The FYK20DA series of pressure-controlled operation devices can be used to trip in and out and replace the pipe string in a pressurized environment, enabling the rapid and smooth connection of production-enhancement measures and improving the extraction efficiency of oil and gas wells. In the extraction of shale gas, frequent production-enhancement operations require the support of efficient pressure-controlled operation equipment. This device can meet this requirement and ensure the continuous and stable extraction of shale gas.
Industry development trends:
Jilin Oilfield Engineering Technology Service Company has been leveraging its distinctive technologies such as major repairs of oil and water wells, minor repairs of gas wells, and pressure-maintained operations of water wells to expand into external markets. In 2024, it achieved remarkable results in markets including Qinghai, Daqing, North China, and Hainan (Southern Exploration Region). The company has cumulatively generated revenue of 62 million yuan and completed 424 operations, including minor repairs, pressure-maintained operations, and major repairs.
