Technology Brief
The combination of different burning rates of gunpowder is used to produce multi-stage combustion and form multi-stage pulses to create a continuous effect on the formation, while the heat generated during the reaction of the system is used to increase the temperature in the seam and reduce the resistance to the flow of crude oil to achieve the purpose of improving the effect.
application scope
It is suitable for the characteristics of rock formation fracturing and seam formation, fast-firing and fast-acting agents produce multiple fractures, while medium and slow-firing and fast-acting agents extend the fractures by continuous pulse action.
technical characteristics
1、Improved the utilization rate of energy, the structure design of the charge is more reasonable, and the process of action under the oil well is more scientific;
2、Improved the amount of charge, which will not damage the casing;
3、Prolonged action time on the formation, due to the increased amount of medium and slow burning rate, the downhole action time is extended, which is conducive to extending the fracture;
4. a significant increase in thermochemical energy, which improves the overall fracturing effect and reduces costs
5. cable transmission can be used, which is safe and fast
6、Multiple combinations of pillar sizes are available, which is convenient to apply to various sets of variable wells.
technical advantage
Our company has a full set of multi-pulse thermochemically loaded fracturing equipment, chemicals, teams and related qualifications, and has many years of experience in technical services related to multi-pulse thermochemically loaded fracturing technology. Our company can design targeted construction solutions according to specific oil and gas well conditions to effectively address customer needs. The company has promoted the application of the technology for more than 1,500 wells in major oilfields, and the technology has now become a routine treatment measure before betting on water injection wells in low permeability oilfields such as Changqing Oilfield and Yanchang Oilfield.
