METHOD AND APPARATUS FOR IMPROVING WIRELINE DEPTH MEASUREMENTS |
摘要 |
<p>Wireline depths are estimated using cable depth measurements and accelerometer depth measurements made over a time interval encompassing the time for which the wireline depth is being estimated. A least squares smoothing filter or a weighted least squares smoothing filter may be used. Problems caused by washouts in the borehole are also addressed.</p> |
