Cementing is an important step during drilling operation

Cementing, the construction operation of running casing into the well and injecting cement into the annular space between the wellbore and the casing. It is an indispensable and important link in the process of drilling and completion operations, including casing running and cement injection.

Cementing technology is a multi-disciplinary comprehensive application technology with the characteristics of systematic, one-time and short time. The main purpose of cementing is to protect and support the casing in oil and gas wells, and to seal oil, gas and water formations.

In drilling operations, there are generally at least two cementing (production wells), and up to 4 to 5 cementing (deep exploratory wells). The top cementing is surface casing cementing, which acts as a "mud passage, oil and gas gateway". Before drilling the next time, a blowout preventer should be installed on the surface casing to prevent blowout. A mud pipe should be installed above the blowout preventer, which is a passage for drilling fluid to return to the mud pool. During the drilling process, technical casing is often used to cement the well. It plays the role of "consolidating the rear and safely exploring the road". Like highway tunnels and mine roadways, well collapse, high pressure and unstable formations will also be encountered during the drilling process. At the same time, it is also to have a retreat in the forward "road exploration" and play a "rescue". effect.

There are three main aspects to improve cementing quality:

1. Improve the displacement efficiency of drilling fluid;
2. Prevent oil, gas and water from channeling outside after cementing;
3. Improve the cementing and sealing quality of the cement ring interface.
