The Application Study Of Geochemistry Mulogging Technology In Xifeng Oilfild

By means of analysing core or cuttings , geochemistry mudlogging can quantitatively examines the quantity of oil and gas in the reservoir,and it is the effective means of evaluating oil layer and gas layer.《The application study of geochemistry mudlogging technology in Xifeng Oilfild》analyses the geglogy condition ,sedimentary facies,reservoir , Physical property,oil character ,associating the character of reservor and oil layer and shape of evaporating pattern, defines oil-water area.First,the article set up interpreting means and chart of Geochemistry well loging technology of Xifeng Oil field,then,unites ration fluorescent date and geochemistry mudlogging date,set up interpreting chart of geochemistry bright spot M and equivalence oil content,introduces the means of forecast outcom in Xifeng oil field. We calibrate the date in order to avert the disturbance of time and other material.The article also find out the means of calculating porosity and oil saturation and density of reservoir,then establish the interpreting chart of porosity and oil saturation of geochemistry mudlogging.The article change the history that physical property cannot be got at well site,change the traditional iterpreting means of Xifeng Oil field.The technique innovation is that the article unite Geochemistry mudlogging data and ration fluorescent date, set up interpreting chart of geochemistry bright spot M and equivalence oil content,introduce the means of calculat the output using deliverability divisor. In order to verify the interpretting method and interpretting chart,we interpretted 38layers of 25 exploration well of Xifeng Oil Field,the coincidence rate attain to 75%.
