This article delves into the functions, key components, and significance of crown blocks in drilling. Functionality of Crown Blocks The primary role of a crown block is to facilitate the lifting of heavy loads, such as drill strings, casing strings, and other materials required in drilling ...
Transforming drilling fluid into cementing fluid to replace cement slurry by adding curing agent and other necessary additive is called MTC cementing technique.It has unparalleled advantages than conventional cementing.This article introduces emphatically its solidified principle,indoor evaluation,injection alloca...
by injection of gas to resolve deep into the pile quality problems; to ensure full bi-cement mixing pile of pile length to pile quality; at the same time easy to block the tube, increase the number of ejected stirring cement powder or slurry, greatly improving the efficiency of construction...
In the course of time these materials carbonize and block the fractured zones. Cementing Proper cementing of geothermal wells requires that the cement slurry should rise uniformly and continuously from the casing shoe to the ground level. If it is envisaged that the formation cannot be adequately ...

attachment, which means comprise sharp protrusions operative to penetrate the surface of the plug and/or the attachment in order to inhibit or impede relative rotation between the plug and the attachment when a rotary drill bit is brought into contact with the plug, in order to drill out the...
2g. (8) The PDM and PDC (polycrystalline diamond compact) bit are run into hole to grind the cement plug in the completion string. After wellbore cleaning, the drill string is pulled out hole, as shown in Fig. 2h. Fig. 2. Key processes of liner differential rotary drilling with double...
Cementing is the operation of pumping a cement slurry between the casing and the formation, and can be performed by injection into the annulus from inside the casing. The cementing (primary cementing) serves to rigidly connect the casing to the formation and to guarantee the hydraulic insulation ...
