... setbacks. Real-time detection and measurement of vibration are critical for monitoring and enhancing drilling efficiency. The rig's drilling system supplies energy to drive the drilling process. Figure 2 ROP vs shock# Addressing downhole drilling vibration challenges can begin in the planning...

...), a hammer seat (#2) and an impact hammer (#3). During the ATIID drilling process, the drilling fluid causes the disk valve to rotate. The through hole on the rotary valve is periodically connected with the flow channel of the tool, so that the drilling fluid repeatedly switches the flow channel to produce...

... Abstract Direct feedback from the drilling process will be key to enhance overall drilling performance further, improve steering and will help detect drilling dysfunctions early. This is especially true for demanding drilling applications, such as drilling in difficult geological formations...

... capacity of the drilling fluid system is more than 45%. Throughout the drilling process, there was no downhole complex occurred. This OBM system has been wildly used in Keshen Block. drilling fluid chemistry drilling fluid selection and formulation drilling fluid property drilling fluids...

.... To optimize the entire drilling process from different angles, an integrated approach is required to combine the knowledge and expertise from different disciplines. A robust geomechanical model and detailed diagnostics of the borehole instability related problems are key and form the basis for the drilling...

... releasing effect and reduce rock compressive strength to improve the rock-breaking efficiency is put forward, and a matched WSDB is developed. The mechanical specific energy required in the rock-drilling process can be greatly reduced, at the same time DOC characteristics of the bit are dynamically adjusted...

... protectors and rapid drilling technology. Finally, according to drilling process, 5 integrated casing wear prevention technologies are proposed, including the basic design of wear prevention, the design of expanding wear prevention, the controlling of well quality, usage of wear prevention tools, measures...

... Abstract Most drilling problems have been accepted as an inherent part of the drilling process. As a result, there has been a great amount of effort put forth to find solutions for said undesirable events after they occur. Much of the industry's current drilling activity is happening...

... were found to cause instability problems due to water phase. Gas drilling fluid, oil based drilling fluid or all-oil drilling fluid can minimize the instability problem which is caused by shale hydration. However, we must be sure that there won't meet water zone in gas drilling process, and gas...

... Abstract MPD means an adaptive drilling process used to control precisely the annular pressure profile throughout the wellbore. The objectives are to ascertain the downhole pressure environment limits and to manage the annular hydraulic pressure profile accordingly. MPD is intended to avoid...
