HEAVE COMPENSATED WIRELINE LOGGING WINCH SYSTEM AND METHOD OF USE |
摘要 |
A computer controlled heave compensation wireline logging winch system a nd method of use that compensates for the effects of wave motion on floating installations performing wireline logging measurements. A wireline winch and wireline cable with a logging measurement tool attached is installed on a floating installation. Vessel vertical movement is measured and is physically compensated for by a change in speed of the wireline cable so that the logging data is obtained at a controlled speed. Any error in this physical compensation is detected by a depth measurement system and is used to adjust the true depth at which the logging tool measurements are being recorded.
