In order to understand critical vibrations of a drill bit such as stick-slip and bit-bounce and their wave propagation characteristics through a drillstring system, it is critical to model the torsional, longitudinal, and flexural waves. The objective is to model these waves propagating through the drillstring in a computationally efficient way. Here, a modeling method based on an acoustic tran...
Drilling volumes should be increased in order to increase hydrocarbon production, but this is impossible without the usage of high-quality drilling tools made modern structural materials. The study has analyze design, technological and operational methods performance various materials highlighted prospects method applications. scientific novelty consists development a new analytical model PDC d...
In the oil, gas and geothermal drilling industry, use of a drill pipe is vital for its as an addition to length depth. Another function channel high pressure mud (drilling fluid / fluid) bit. During operation, several problems were encountered, such broken, bent, leaking or wash-out pipes. This very detrimental company because time replace new will take long time, disrupt program which result i...
Modern research in high energy physics depends on the ability to analyse massive volumes of data in short time. In this article, we report on DeLorean, which is a new system architecture for high-volume data processing in the domain of particle physics. DeLorean combines the simplicity and performance of relational database technology with the massive scalability of modern cloud execution platf...
In this study, a nickel cladding layer with bionic convex strip structure was applied to the surface of an aluminum alloy drill pipe, and laser technology used improve wear resistance pipe. Firstly, by observing morphological characteristics shell surface, ratio width strips spacing between obtained as 0.39–0.53, thus model constructed. Numerical simulations were performed, results showed that ...
