A data processing method for post-drilling data

Abstract

The invention discloses a post-drilling data processing method. The method comprises the following steps: data acquisition is carried out, a pre-drilling calculation analysis result for an exploratory well is acquired, and post-drilling data of the exploratory well are acquired; post-drilling data are pretreated, the post-drilling data are calculated and analyzed to acquire a post-drilling calculation analysis result corresponding to the pre-drilling calculation analysis result; comparative analysis is carried out, based on the comparative analysis on the pre-drilling calculation analysis result and the post-drilling calculation analysis result, a comprehensive analysis processing result for the post-drilling data is acquired, wherein the comprehensive analysis processing result comprises rationality judgment on the pre-drilling calculation analysis result and / or reasons for deviation of the pre-drilling calculation analysis result. The method of the invention can reduce uncertainty of the pre-drilling geological data calculation analysis result, the geological state prediction success rate can be improved, and the oil-gas exploration risks are finally reduced.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to a data processing method for post-drilling data. Background technique [0002] In the geological exploration process, the geological attributes of a specific area are usually analyzed and calculated based on the current geological data to obtain the analysis and calculation results of the geological attributes. Due to the particularity of the geological exploration process, the analysis and calculation results of geological attributes have certain uncertainties, especially the geological data collection for the area corresponding to the exploration well before drilling (pre-drilling) is not sufficient, which further increases the pre-drilling. Uncertainties in the results of analytical calculations of geological properties. [0003] For a single exploration well, the usual exploration and development process is to first analyze and calculate according to the geological data...

Problems solved by technology

[0005] However, in actual operation, due to the complex and changeable geological conditions in reality, the actual data after drilling of the previous exploration well cannot conform to the actual situation of the current exploration well. Analyzing and researching the results of analysis and calculations cannot effectively reduce the risk of exploration and development of follow-up exploration wells
