Product Description

Product Description

 

Tubing and casing are two pivotal components in the realm of oil wells. Tubing, crafted from high-quality materials such as stainless steel, galvanized steel, or resilient plastic, is dedicated to the efficient transportation of oil and gas from the depths of the reservoir all the way to the surface, all while adeptly supporting the substantial weight of both the drill bit and casing. Meanwhile, the casing plays a crucial role during the drilling operation, as it is meticulously installed to secure the borehole, reinforce the strength of the well wall, ensure the flawless completion of oil and gas well cementing, stabilize the geological formation, and effectively prevent any potential collapse of the well wall.

Product Details

What distinguishes casing from tubing in oil well operations?

Casing and tubing are vital in oil well operations, each serving distinct purposes that are critical throughout the well's lifecycle. Below is a detailed comparison to elucidate their differences:

• Casing is installed at the drilling phase, providing essential protection and stability to the wellbore. Tubing is employed during production to efficiently transport oil or gas from the depths of the well to the surface.

• Casing ensures structural integrity and provides necessary isolation from surrounding formations. Tubing serves as the conduit for the seamless flow of oil or gas towards the surface.
• Their distinct installation timing and specific functionality are what set casing and tubing apart in the realm of well operations.

Feature

The OCTG casing is a fundamental component in well-drilling operations. Once the drilling is complete, this robust pipe is meticulously lowered into the well. The casing firmly seals against the well wall using high-strength cement. This crucial step sets the stage for the perforating gun's precise operation, allowing it to strategically perforate the target layer. This process is essential for enabling the seamless flow of the tubing through the rock formation, cement sheath, and casing. At the core of the well, the tubing pipe extends to the surface, completing a vital link in the oil extraction process. The main functions are:

(1) Reinforce the well wall, providing an essential safeguard against formation collapse;

(2) Expertly seal diverse tubing layers and water layers, ensuring efficient layered mining operations;

(3) Facilitate the implementation of advanced measures such as fracturing and acidification, alongside essential maintenance operations.

(4) Form a streamlined tubing flow channel, expertly collaborating with the tubing pipe to optimize the tubing production process.
