Three properties of polycrystalline diamond compacts

When talking about the properties of PDC composite sheets, people often talk about its three major properties, namely abrasion resistance, impact resistance and thermal stability.

       In the actual drilling process, the drill bit will drill stones with different compositions, different hardness and different abrasiveness, which will require the PDC bit to be sufficiently wear-resistant, so as not to consume too quickly and increase drilling costs; it also requires the PDC bit to be sufficiently impact-resistant and not As for the rupture or damage of the composite sheet or the drill bit due to impact during the drilling process, the PDC drill bit is also required to have good thermal stability, so as not to be deformed by heat in the underground drilling environment of high temperature operation.

       When testing the performance of PDC compacts and PDC bits, people prefer to obtain quick data feedback through laboratory testing rather than directly verifying the quality through field testing in the oil field, because field testing requires too long Bear some testing costs and risks. The establishment of a well-equipped laboratory with advanced technology is a must for every PDC product manufacturer and the primary R&D and production condition. Only in this way can we detect and develop high-quality products suitable for the market.

       Laboratory testing can only test the performance of PDC composite sheets by imitating the actual drilling and processing conditions as much as possible. Ultimately, the quality and stability of the products can only be verified through field application in oil fields. Therefore, manufacturers of PDC composite sheets need to cooperate with Only by maintaining close cooperation between PDC drill bit manufacturers and final oilfield users can the products be made well and refined.
