Horizontal Directional Drilling-Length Detection Technology While Drilling Based on Bi-Electro-Magnetic Sensing
The drilling length is an important parameter in the process of horizontal directional drilling (HDD) exploration and recovery, but there has been a lack of accurate, automatically obtained statistics regarding this parameter. Herein, a technique for real-time HDD length detection and a management system based on the electromagnetic detection method with a microprocessor and two magnetoresistiv...
متن کاملAnalysis of the Impact of Managed Pressure Drilling Technology on Current Casing Program Design Methods (TECHNICAL NOTE)
This paper analyzed the characteristics of managed pressure drilling (MPD) technology and impact of wellhead back pressure on the wellbore annulus pressure profile, and found that the application of this technology provides room for improvement to the current casing program design. Meanwhile, the equivalent density of drilling fluid in wellbore annulus needs to consider the impact of back press...
متن کاملThermal Response Test While Drilling
Knowledge of the ground thermal conductivity is of importance when designing borehole heat exchanger (BHE) systems. As thermal conductivity for any specific rock type varies due to its mineral content, porosity, pore fluid and anisotropy, it is preferable determined in-situ. Choudhary (1976) suggested a method for determining the thermal conductivity which analysed the heat transfer during the ...
متن کاملThe Study of the Transducer Used in the Acoustic Telemetry Technology While Drilling
The technology of bi-directional data transmission between the well bottom and ground play an increasingly important role in modern drilling technology while drilling. The technology of acoustic data transmission while drilling can achieve higher band rate compared with the traditional. The transducer is one of the most imp-ortant components of it. This article has simulated the piezoelectric c...
