On April 1, the two 24-inch large-size steel diamond drill bits produced by the petroleum engineering company Jiang Diamond Co., Ltd. were successfully exported to Iraq, marking that the company has already developed and manufactured large-diameter diamond drill bits.
In 2007, Jiang Diamond Co., Ltd. launched the diamond industry project. One year later, the company's Wuhan Drilling Manufactory was officially established. After nearly five years of development, it has already met the specifications of 3 inch and a half - 24 inch steel body and carcass standard. Dimensional diamond drill bit and processing and manufacturing capability of impregnated, coring, mixing and twin-core diamond drill bits.
After receiving the production task of exporting drill bits, the company quickly organized technical R&D personnel to analyze the topography and geomorphology of the area. There are many layers of leakage in the area, and there are multiple pressure systems in the underground. The general 24-inch drill can only hit 2000 meters. In the case of the left and right, by refining various technical indicators, optimizing the process procedures, and carefully organizing the organization, it took only more than 20 days to complete the processing task of the drill bit.
Due to the limitations of key technologies and processing equipment such as complex 3D model programming techniques and tool application techniques, it is very difficult to manufacture large-diameter diamond drill bits. Currently, only a few drill manufacturers have mastered the key technologies for large-scale drill manufacturing. The successful development of this product not only solves the practical engineering problems such as the large-size drill bit pressure increase, the excessive torque, the single drill bit stroke length, etc., but also accumulated valuable experience for the company's processing of large-size diamond drill bits, filling the The blank of the company's large-size steel diamond drill bit processing capability. It is reported that there will be three 26-inch large-size steel diamond drill bits exported to Iraq this month.
