Embodiment 1
[0036] The invention discloses a method for evaluating reservoirs by using data during micro-drilling to calculate logging porosity while drilling, comprising the following steps:
[0037] a. Collect micro-drilling time data of drilled wells;
[0038] b. Combining the drilled micro-drilling data and the corresponding formation porosity data to establish a correlation model between the micro-drilling data and the formation porosity data;
[0039] c. According to the established correlation model between the micro-drilling data and formation porosity data, the logging porosity is calculated while drilling using the micro-drilling data while drilling;
[0040] d. Combined with cuttings logging data, set the formation porosity of the conventional tight lithology section to a default value lower than the lower limit standard of reservoir porosity, and complete the reservoir evaluation.
Embodiment approach
[0042] Refer to the attached figure 1 , 2 And 3, the best mode of implementation of the present invention is as follows:
[0043] A method for evaluating reservoirs by calculating mud logging porosity while drilling using micro-drilling data, the steps comprising:
[0044] 1. Collect the micro-drilling time data of the same layer that has been drilled in the same block, and combine the corresponding formation porosity data to establish a correlation model between the regional micro-drilling time data and the formation porosity data.
[0045] The corresponding formation porosity data is: relatively accurate formation porosity data obtained by various means, which may be logging interpretation porosity data, core analysis porosity data, and the like.
[0046] The correlation model between the micro-drilling time data and formation porosity data of the establishment area is as follows: using the micro-drilling time data and the corresponding porosity data of the same layer that...
