Problems solved by technology

[0007] Conventional approaches avoid common operational difficulties of CRPM in: (i) complex BHA modeling and results; (ii) imprecise modeling and results due to incorrect input data; and (iii) failure to incorporate modeled results into Used in conjunction with real-time vibration data to optimize the drilling process
That is, in the prior art, the dynamics analysis is not done in an integrated, closed-loop manner, but mainly or all of the dynamics analysis is performed during the drilling planning phase, leaving only limited opportunities for optimization of drilling operations

Embodiment Construction

[0021] In the interest of clarity, the following disclosure does not describe all features of an actual implementation. It should be clear that during the development of any actual implementation, and in any such project, numerous engineering and design decisions must be made to achieve the developer's specific objectives and sub-objectives, which may vary from one implementation to another. different. In addition, care needs to be taken to give proper engineering and programming practices to the environment. It should be appreciated that such a development effort can be complex and time consuming, but nonetheless would be a routine procedure for those of ordinary skill in the art.

[0022] Referring to FIG. 1 , a block diagram of high-level functionality of an integrated drilling dynamics system 10 according to one embodiment of the present invention is shown. As shown in Figure 1, the present invention involves the collection and analysis of various operational data relate...

Abstract

A method and apparatus for controlling a drilling operation involving the rotation of a bottom-hole assembly carried by a drillstring. In one embodiment, an integrated, closed-loop rigsite analysis system is provided for acquiring and analyzing real-time mud logging and downhole data, and displaying in real-time values of one or more operator-controllable parameters, along with dynamic critical values of at least one controllable operating parameter, thereby enabling an operator to modulate such parameter on a real-time basis to optimize operation. The integrated information is derived by intelligent combination of data into meaningful and useable information that can be displayed in an informative manner.

Description

[0001] related application [0002] This application claims priority to earlier Provisional Application Serial No. 60 / 440,819, filed January 17, 2003, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to the field of oil and gas production, and more particularly, to oil and gas well drilling equipment. Background technique [0004] Drilling costs are an important factor in determining the financial return on oil and gas investments. This is especially true for offshore environments, where operating costs are high and wells prone to drilling problems. In particular, severe vibrations have been shown to be detrimental to bottom hole equipment used to drill oil and gas wells. Of these, lateral vibrations (especially back rotation) are often associated with drill string fatigue failures (wearing, twisting), excessive bit wear, and measurement-while-drilling ("MWD") tool failures. Lateral vibration is ca...
