摘要
Abstract
In the directional drilling,the practical trajectory of the well is often inconsistent with the projected objective.The quantitative analysis of the error is crucial for the track adjustment and accuracy control.According to the principle of the vector manipulation in directional drilling,the vector error between the practical drilling direction of the deflection tool and the controlled direction of the designed well has been studied in this paper.Based on the practical drilling trajectory parameters,a simple calculation method for the quantitative analysis of the error and the directional angle and intensity of the comprehensive effects which produce the error has been deduced.The method can be used to analyze the aeolotropy and the natural oblique effect of strata if it is sure that the error is produced by stratum deflecting characteristics.The method has been used successfully in the directional drilling projects of multi-trip and short-roundtrip.Furthermore,it is of the practical value for the trajectory accurate adjustment in the long-roundtrip engineering of measurements while drilling关键词
