Study Notes
Pump Types and Functionality
- Single acting pumps move fluid only on the forward stroke, known as Triplex.
- Double acting pumps move fluid on both the forward and backward strokes, referred to as Duplex.
- A basic pump comprises a piston (the liner) that reciprocates inside a cylinder.
Well Cementing
- The primary function of well cementing is to secure the well casing in place and seal the annular spaces.
- Well cementing enhances wellbore stability by preventing fluid movement between different geological formations, reducing the risk of blowouts and reservoir contamination.
- The cement sheath plays a critical role in isolating different pressure zones and preventing fluid migration between them.
- Proper centralization in well cementing is significant as it ensures uniform cement coverage around the casing, which is essential for effective sealing.
- Zonal isolation refers to the ability of cement to separate different geological zones within the well, preventing fluid communication and ensuring integrity throughout the wellbore.
