补偿中子测井套管井影响校正方法
Correction for Compensated Neutron Log in Cased Holes
摘要
Abstract
The cased compensated neutron logging (CNL) has not directly provided the logging engineering value in the logging application . The model parameters of the CNL Monte Carlo numerical simulation method are determined by openhole numerical simulation and experiments . Based on studying the openhole borehole influence conditions , the influences of the casing and cement thickness on the compensated neutron logs from cased holes are also investigated and the casing and cement effect factor charts for the cased hole CNL are established .Based on the correction of the cased hole compensated neutron log by the correction chart , the formation porosity value can be directly show n from the corrected cased hole compensated neutron log . Comparing with the openhole logs ,it shows the through-casing compensated neutron logging has a good effect and consistency with it .关键词
