Embodiment 1
[0026] The method of using the internal samples of each layer to carry out weighting to compile the well logging crossplot, the steps are as follows:
[0027] Step 1: First set the 5 well numbers of J33-22, J42-21, S231, W19-8 and Z43 in the target layer of the oil zone to be tested, and use a coring tool to test the target layer of the oil zone 191 cores were taken from the preset sampling depths in five wells whose well numbers were J33-22, J42-21, S231, W19-8, and Z43, and the 191 cores were tested with a physical property analyzer for the cores. The corresponding parameters, combined with the logging data and mud logging data of the corresponding core, under the condition of the sampling depth of the core as the analysis sample and the floating range set based on the sampling depth, optimally segmented according to the ordered quantity The method divides the target layer in the well into 48 reservoirs with layer numbers 1, 2, 3...48 respectively, and achieves that the logg...
Embodiment 2
[0033] The method of using the internal samples of each layer to carry out weighting to compile the well logging crossplot, the steps are as follows:
[0034] Step 1: First set the target layer that needs to be tested in the oil zone, use a coring device to take out 95 cores at the preset sampling depth in the target layer that needs to be tested in the oil zone, and use the physical property analysis for the 95 cores The corresponding parameters are tested by the instrument, combined with the logging data and mud logging data of the corresponding core, under the conditions of the sampling depth of the core as the analysis sample and the floating range set based on the sampling depth, according to the orderly In order to achieve optimal segmentation, the target layer in the well is divided into 33 reservoirs with layer numbers 1, 2, 3...33, and the logging attribute parameters inside each divided reservoir can be determined by one Acoustic time-difference logging parameter val...
Embodiment 3
[0040] The method of using the internal samples of each layer to carry out weighting to compile the well logging crossplot, the steps are as follows:
[0041] Step 1: First set the 18 wells of the target layer that need to be tested in the oil zone as shown in Table 3. In the wells corresponding to the well number, use the coring device to test the 18 wells in the target layer of the oil zone as shown in Table 3 251 cores were taken from the preset sampling depth of the well corresponding to the well number, and the corresponding parameters were tested by the physical property analyzer for the 251 cores, and combined with the logging data and mud logging data of the corresponding cores, Under the condition of the sampling depth of the rock core used as the analysis sample and the floating range set based on the sampling depth, the stratum of the target layer in the well is divided into layer numbers 1 and 2 according to the optimal segmentation of the ordered quantity , 152 re...
