Pressure opening is a common drilling operation used to open a hole in the formation to allow oil and gas to be extracted from the wellbore. Prior to this operation, an evaluation and drilling plan were required.

Assess the geology:

Before performing a pressure opening operation, you first need to assess the geology. This includes determining the height, composition and pressure of the reservoir. For different reservoirs, it is necessary to select the appropriate pressure opening tools and drilling fluids.

Design drilling program:

After determining the geology, a specific drilling plan needs to be designed. This includes selecting the composition of the drilling fluid and determining parameters such as flow and displacement. Wellbore stability and the impact on the formation need to be considered when designing the solution.

Installation tools:

After the drilling plan is designed, it is necessary to install a pressure opening tool. This process requires attention to safety. It is also necessary to check the integrity of tools and pipes to ensure normal operation.

Adjusting drilling fluid:

After the tool is installed, the properties of the drilling fluid need to be adjusted. This includes adjusting parameters such as density, viscosity and flow to ensure adequate scouring capacity and good working effect.

After adjusting the drilling fluid, the pressure opening operation can begin. This process needs to control the height, size and position of the opening holes according to the design scheme. At the same time, it is necessary to know the working condition of the opening in real time through the monitoring system.

Test and adjust:

After the borehole operation is completed, the wellbore is tested to assess the effectiveness of the borehole drilling and oil and gas production. For unsatisfactory places, adjustments need to be made to improve the opening effect.

Clean wellbore:

After testing and adjustment, the wellbore needs to be cleaned to ensure that no impurities and residues are left in the wellbore. This process requires care and patience, as impurities and residues in the wellbore can affect subsequent work.

Stop operation:

After completing all of the above steps, you can stop the pressure opening job. This process requires the shutdown of the relevant equipment and tools, and the maintenance and maintenance of the equipment and tools. At the same time, it is necessary to summarize and reflect on the working process in order to better carry out the next operation.

In summary, pressure opening is a complex drilling operation. Prior to this operation, the geology was assessed, drilling plans were designed, tools were installed, drilling fluids were adjusted, pressure openings were performed, tests and adjustments were made, the wellbore was cleaned, and the operation was stopped. These steps require advanced knowledge and experience, as well as attention to safety and patience.
