The Recognition of Abnormal Gas Measurement Data and Oil and Gas Show

The continuous promotion and application of new drilling technology greatly improves the speed of drilling, protects the reservoir from pollution, but bring challenges to the logging explaining of oil and gas layers evaluations. The debris samples are very small, have poor representation, carry oil and gas information which has been wiped out by the drilling fluid.To find the abnomal oil and gas through the debris makes incredibly difficult. The study improves the divided measures of the gas thickness,which use the "3H method" to identify oil and gas show, improve the identification level of gas measurement data and oil and gas show.
