wherein T is g For measuring total hydrocarbon, T Z Is the basic value of the air measurement,

And (3) a formula III: ψ=nc 4 /iC 4 ，
Equation four: l (L) h ＝C 1 /(C 2 +C 3 +iC 4 +nC 4 +iC 5 +nC 5 )；
Thirdly, calculating the M value of the comprehensive evaluation factor of the gas measurement of each well layer, identifying the oil-gas content of the reservoir according to the M value,
wherein T is g For measuring total hydrocarbon, T s To highlight the coefficient, W h Is hydrocarbon humidity ratio, psi is isomerism ratio, L h Is the light-to-heavy hydrocarbon ratio;

and fifthly, for the new well, obtaining the gas detection comprehensive evaluation factor M value of the new well through the second step and the third step, and giving out a gas detection comprehensive interpretation conclusion of the new well according to the block gas detection interpretation standard established in the fourth step.
Hydrocarbon component C 1 To C 5 The value includes C 1 、C 2 、C 3 、iC 4 、nC 4 、iC 5 And nC 5 Values.
The comprehensive interpretation conclusion of the gas measurement comprises: the reservoir is a dry layer or an oil-bearing layer.
For complex geological oil reservoirs, the gas measurement parameters of gas measurement of whole hydrocarbon have strong influence on gas measurement interpretation results due to the derivative parameters of the salient coefficient, the hydrocarbon humidity ratio, the isomerism ratio and the light-heavy hydrocarbon ratio, but the interpretation results by using different single parameters are often not uniform, and the difficulty is brought to the grasp of comprehensive interpretation results.
The method is suitable for gas measurement interpretation of complex geological oil reservoirs, and the gas measurement comprehensive evaluation factor M constructed by the gas measurement parameters and the derived parameters is used for identifying the oil and gas contents of the reservoir, so that a gas measurement comprehensive interpretation standard can be established, the problem that the interpretation results of different single evaluation parameters are not uniform in the prior art is effectively solved, and the process for identifying the oil and gas contents of the reservoir is simple and efficient.
The invention provides a concept of an air-test comprehensive evaluation factor M, and utilizes the ratio of positive and negative correlation derived parameters to amplify a correlation signal so as to clearly and comprehensively explain a conclusion.
The method is simple and efficient in application and verification of a plurality of broken block complex oil reservoirs, solves the problems that the interpretation results of single evaluation parameters are not uniform and comprehensive interpretation is not easy to grasp, and improves the coincidence rate of comprehensive interpretation of gas detection.
(1) Highlighting coefficient T s The abnormal change amplitude of the gas-measuring whole hydrocarbon is reflected, and the influence of the drilling fluid with the same density on the detection value of the gas-measuring parameter is not eliminated. T (T) s The higher the value, the greater the likelihood of hydrocarbon presence in the formation.
(2) Hydrocarbon humidity ratio W h The ratio of heavy hydrocarbon to hydrocarbon gas components is reflected, and the ratio is an index of the basic characteristic type of oil gas. The hydrocarbon humidity ratio of the same reservoir is relatively stable in a region, and the water layer and the dry layer extend outwards from the region around the data region. W (W) h The higher the value, the greater the likelihood of hydrocarbon presence in the formation.
(3) The isomerism ratio psi reflects the quality of the oil. The normal butane content in the oil layer is higher than that of the isoputane, the magnitude of the value phi can judge the light and heavy of the oil quality and evaluate the oil layer by interpretation, and the smaller the value phi is, the greater the possibility of oil gas in the stratum is.
(4) Light to heavy hydrocarbon ratio L h Reflecting the ratio of methane to the sum of the other hydrocarbon gas components. L (L) h The smaller the value, the greater the likelihood of hydrocarbon being present in the formation.
Comprehensive evaluation factor of gas measurementIn the sub-M calculation formula, T g 、T s 、W h The greater the value, the higher the oil and gas properties; psi, L h The smaller the value, the higher the oil and gas properties. The correlation signal is amplified by dividing the numerator and the denominator, so that the interval range of the oil layer, the oil-containing layer and the dry layer is enlarged, and the accuracy of identifying the oil-gas property of the reservoir is improved.
Application example 1: the oil field of Fushan of Hainan province is used as a research area,
first, collecting the gas measurement parameters in the block, including gas measurement of the total hydrocarbon T g Basic value T of gas measurement Z Hydrocarbon component C 1 To C 5 The values, gas parameters are shown in table 1, and the reservoir oil gas properties conclusions (test oil conclusions) drawn by the test oil are shown in tables 1 and 3.
Second, 4 derived parameters were calculated according to the formula described in example 1: t (T) s 、ψ、L h 、W h The values of the 4 derived parameters are shown in table 2.
Third, the value of the comprehensive evaluation factor M of each well layer is calculated according to the formula described in the embodiment 1, and the value of the comprehensive evaluation factor M of each well layer is shown in Table 3.
And checking the obtained M value through the oil test conclusion of the research area to obtain an air test interpretation standard (shown in table 4) of the research area, solving a comprehensive air test evaluation factor M of 451.14 of the new well A for the new well A belonging to the research area, performing interpretation according to the air test interpretation standard shown in table 4 to obtain an air test comprehensive interpretation conclusion of the new well A as an oil layer, and checking the air test comprehensive interpretation conclusion through the oil test conclusion of the new well A to be consistent. Compared with the existing technology for identifying the reservoir oil and gas property by adopting a single evaluation parameter, the method provided by the invention has higher accuracy in identifying the reservoir oil and gas property and accords with the reservoir oil and gas property conclusion obtained by actual oil testing.
According to the method, the oil-gas-bearing property of the reservoir is identified by adopting the gas measurement comprehensive evaluation factor M constructed by the gas measurement parameters and the derivative parameters, so that the difficult problem that the conclusion of interpretation of a single evaluation parameter on a well layer is not uniform and the comprehensive interpretation conclusion is difficult to grasp is solved, and the coincidence rate of the gas measurement comprehensive interpretation is greatly improved.
The technical characteristics form the embodiment of the invention, have stronger adaptability and implementation effect, and can increase or decrease unnecessary technical characteristics according to actual needs so as to meet the requirements of different situations.
