我队在黑龙江省石油化工研究所的大力支援下，对J-19-C高强胶进行了硬质合金钻头粘结和现场试验。先后共制作钻头35个，其中无岩心钻头23个，取心钻头12个，在辽源勘探区不同孔深和岩层进行了16次试验，取得了较好效果，达到了效率高、成本低、简化了焊接钻头工艺等目的。 My team in Heilongjiang Petrochemical Institute of the strong support of the J-19-C high-strength plastic carbide drill bit bonding and field trials. A total of 35 drills have been produced, of which 23 were non-core drills and 12 were coring drills. Sixteen tests were conducted at different hole depths and strata in the Liaoyuan prospecting area and achieved good results with high efficiency, low cost and simplified The purpose of the welding drill technology.
