Bohai Drilling hole drilling technology Drilling String Crossover Sub services company servicing area, technicians are using the new high Jianfeng means within the drill pipe surface detected. This new device is a spy device that the company developed a manual drill within the video, has been the national utility model patents, to fill the gap.
This set of devices using optical, electronic and mechanical technology, capable of surface corrosion in the oil drilling conventional drill hole defects, cracks and other rapid detection and real-time display, store test data for detecting an inner diameter of 70 mm -150 mm drilling, having a 70-degree angle and 90-degree vertical side perspective, the detection rate of 0.2 m / sec, can be application-specific software for quantitative analysis.
Since September 2013 put into use in the field since the drill manual video endoscopic device has been in Dagang Downhole Stabilizers Oilfield, Jidong Oilfield drilling site applications, the cumulative detection drill 3.3453 ten thousand, was found to have different shapes erosion pit, defect etch pits drill with 630, downgrade or scrap timely, effectively avoiding the drilling failure, reduce drilling rig losses caused by the failure of more than 400 million.
