Based on the introduction of working principles various automatic vertical drilling systems (VDS), latter are divided into rotary push type and sliding type. Then technical advantages applicable scope types tools analysed. Combined with latest domestic application progress typical case analysis system, future development direction technology is predicted. The results show that, existing can bet...

The relevance of the application hydraulic thruster technology is determined by technological limitations drilling both vertical and horizontal wells. existing experimental studies confirm effectiveness technology, but its widespread implementation hindered lack scientific foundations for operation in combination with a downhole motor bit. Our research methodology includes methods analyzing tec...

Managed pressure drilling is a sophisticated pressure control method which is intended to meet increasingly high demands in drilling operations in the oil and gas industry. With this method, the well is pressurized and the drilling mud is released through a control choke which can be used to actively control/reject pressure variations. Such a control system needs to handle several disturbances,...

Core drilling has been widely used in mineral exploration with diamond-impregnated technology. Automation is a critical technology improving core efficiency and reducing costs, but there no complete automation that can control the entire process. In this paper, an electric drive laboratory system was established using programmable logic controller (PLC) A proportional integration differentiatio...

Data is generally expected to continue its exponential growth the next five to ten years. However, it is commonly agreed that the amount of data that currently exist is abundant and that there is still much to achieve with it. The industry, in general, has recognized both the growth and the need to analyze the data. This is also the case with oil well drilling operations. Currently, operators m...
