Modeling and Experimental Study on Drilling Rig Anti-jamming Valve with Bp Neural Network

Article history: Received: 17.3.2015. Received in revised form: 22.9.2015. Accepted: 24.9.2015. An effective anti-jamming system is significant in improving the working reliability of hydraulic drilling rigs. An anti-jamming valve is a core component of an anti-jamming system. A backpropagation (BP) neural network model was established for an anti-jamming valve by analyzing the structure and wo...

The great potential of nanomaterials in drilling & drilling fluid applications

The continuous development of global economy with decreasing in available hydrocarbon sources and increasing discovery and extraction costs due to decrease in-situ oil and gas reservoir, displays the necessity of using new techniques for the improve rate of penetration and productivity in well. Nanotechnology has already contributed significantly to technological advances in the energy industri...
