The importance of solid control systems in the drilling industry
Pub Date:Sep 15, 2025 | Views:89 |
At the site of oil and gas drilling, although the solid control system is not as conspicuous as the drilling rig or the drilling tower, it is the "invisible guardian" of the drilling project,
directly determining the operation efficiency, cost control and safety and environmental protection effectiveness.
As the "purification center" of drilling fluid, the performance of the solid control system is directly related to the success or failure of a single well and the overall benefits,
and it is an irreplaceable key part of the engineering system.
The investment in a single well for oil and gas drilling often reaches tens of millions to hundreds of millions of yuan,
among which the cost of drilling fluid accounts for 15% to 25%, and its efficient recycling is the core of cost control.
When the solid control system is lacking for precise processing, solid impurities such as cuttings and sand particles in the drilling fluid will cause dual cost risks: first,
the excessive sand content will lead to the failure of the drilling fluid function, requiring frequent replacement.
A team equipped with a complete set of efficient solid control systems can achieve a drilling fluid reuse rate of over 85%. Second, impurities can erode drilling tools.
When the sand content exceeds 0.5%, the service life of the drilling tools is shortened by 30% to 50%, and the maintenance and replacement costs for a single well increase by 500,000 to 1.2 million yuan. High-quality systems can control the sand content below 0.2%, significantly reducing costs.
The solid control system is also the "first line of defense" for drilling safety and is crucial for avoiding risks such as blowouts, stuck pipes, and well leaks.
In terms of blowout control, the density of drilling fluid is the core for balancing the bottom hole pressure. The failure of solid control leads to abnormal density - if it is too low,
it is easy to cause formation fluid intrusion and blowout; if it is too high, it may fracturing the formation and cause well leakage, which can easily lead to the scrapping of drilling tools and delays in the construction period.
With the tightening of environmental protection supervision, "zero emissions" and "reduction" have become hard standards for drilling, and solid control systems have become core equipment for green transformation. The solid control system locks down harmful substances through multi-stage purification to prevent leakage and pollution of soil and water bodies, thus protecting the environment.
As a manufacturer of solid control systems, it is necessary to pay attention to three core indicators: The first is the purification efficiency.
Equipment such as vibrating screens, desanders, desilters, and centrifuges, as the core equipment of solid control systems,
need to be selected in combination with the drilling depth and the lithology of the formation. The second is stability.
The system motor, pump set and control system need to be resistant to extreme environments.
The solid control systems produced by Xi 'an Kosun can be selected based on the usage temperature, drilling fluid composition, etc., to meet the processing requirements of customers.
In conclusion, the solid control system has transcended its positioning as an "auxiliary equipment" and has become a "core competitiveness element" that influences cost,
safety, environmental protection and efficiency. For drilling enterprises, choosing a suitable solid control system is the key to reducing costs and increasing efficiency in the short term,
enhancing competitiveness in the long term and achieving sustainable development. In the future, as drilling extends to ultra-deep Wells and shale gas Wells,
the technological upgrade of solid control systems will become an important driving force for the high-quality development of the oil and gas industry.
