Choosing the appropriate perforation method is critical due to factors such as the characteristics of the oil and fluid, formation damage, casing processes and field production conditions. By taking these factors into account, operators can optimize the efficiency and effectiveness of the piercing process.
The two main perforation methods commonly used are positive pressureperforationand negative pressure perforation. Positive pressure perforation involves the use of a high-density perforating fluid to create a column pressure above the formation pressure. This method is suitable for specific scenarios where the formation requires higher pressures to effectively perforate and increase production.
Negative pressure perforation is to reduce the wellbore liquid level to a certain depth, and generate appropriate negative pressure below the formation pressure. This method can be used when reducing wellbore pressure can enhance the perforation process and minimize formation damage. The negative pressure generated helps prevent excessive fluid inflow during perforation, reduces the chance of damage to the formation and optimizes flow dynamics.
By understanding the characteristics of the reservoir and fluids, assessing potential formation damage, considering casing processes, and evaluating production conditions in the field, operators can make informed decisions about whether positive or negative pressure perforation is more appropriate for their situation. Specific information. Analyzing these factors is important to ensure efficient and effective perforation to increase field production.
