Cementing is an important operation in the drilling process. In drilling operations, there are generally at least two cementing (production wells), and up to 4 to 5 cementing (deep exploration wells). The top cementing is the surface casing cementing, which plays the role of "mud passage, oil and gas portal". Before the next spud, a blowout preventer should be installed on the surface casing to prevent blowout. A mud conduit should be installed above the blowout preventer, which is the passage for the drilling fluid to return to the mud pool.
During the drilling process, technical casing cementing is often required, which plays the role of "consolidating the rear and exploring the road safely". Like highway tunnels and roadways in coal mines, well collapse, high pressure and unstable formations will also be encountered during the drilling process. At the same time, it is also for the purpose of "rescue" when there is a retreat in case of danger in the forward "pathfinding" effect. The oil layer casing plays the role of "tight seal, oil and gas portal". Before the oil layer is drilled through, the oil, gas and water are in a state of balance and isolation in the formation, and the oil, gas and water layers are connected into a body after drilling. Therefore, in order to test oil and develop oil and gas, it is necessary to inject cement into the casing of the oil layer to tightly seal the oil, gas and water layers; at the same time, the casing of the oil layer is also a channel for oil and gas reservoirs to the wellhead during production, and it is a temporary warehouse for oil and gas when the well is shut down.
