| description | The invention discloses a method and system for judging the curve form of a sand body, and the method comprises the steps: obtaining a logging interpretation result; selecting a logging curve of a target layer section from the logging interpretation result; averagely bisecting the selected logging curve to obtain an upper curve and a lower curve which are equal in length; carrying out abnormal point removal processing on the upper curve and the lower curve, and respectively counting gamma average values of the upper curve and the lower curve; determining a form threshold value according to the lithologic cycle change of rock core observation and judgment and a curve form artificial judgment result; and calculating the difference value of the gamma average values of the upper curve and the lower curve, and comparing the difference value with the form threshold value to obtain the form of the logging curve. According to the method, judgment errors caused by logging curve dentation and part of abnormal values ca |
