[0071] At present, in oil logging, seismic records have a guiding role in drilling location, drilling depth, etc. Acoustic curve is an important parameter of synthetic seismic records. However, when the measurement of the acoustic curve is inaccurate due to borehole collapse, the synthetic seismic record is also inaccurate. Therefore, after the acoustic curve is obtained, it is usually necessary ...

Abstract

The invention provides a detection method and device for acoustic curve repair, equipment and a storage medium, and the method comprises the steps: obtaining an initial density curve, an initial acoustic curve, a natural gamma curve and a deep exploration resistivity curve, correcting the initial density curve according to the natural gamma curve and the deep exploration resistivity curve, and obtaining a corrected density curve; according to the natural gamma curve, the deep exploration resistivity curve and the corrected density curve, correcting the initial sound wave curve to obtain a corrected sound wave curve; and detecting the well according to the corrected acoustic curve. The density curve is firstly corrected, and then the corrected density curve is introduced into the correction of the acoustic curve, so that the correction quality of the acoustic curve can be effectively improved, a large amount of basic data is not needed, the method is simple and practical, and the economic cost and the time cost are saved.

Description

technical field [0001] The present application relates to the field of well logging engineering, and in particular, to a detection method, device, equipment and storage medium for sound wave curve repair. Background technique [0002] Logging curve is an important parameter of synthetic seismic records, and it has a reference function for drilling operations. Among them, the acoustic curve is a particularly important parameter. However, due to the influence of environmental factors such as borehole wall collapse, the quality of the measured sound wave curve is low, so the sound wave curve needs to be corrected. [0003] In the prior art, basic data such as volume composition, water saturation, and porosity of the rock block can be used to perform petrophysical modeling processing, and then the acoustic wave curve can be corrected by a modeling method. [0004] However, using the above modeling method requires repeated modeling experiments, which is more complex and time-con...
