Embodiment Construction

[0024] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0025] see figure 1 , a reservoir correlation and prediction system using logging porosity data, including stratum channel 1, electrical logging channel 2, altitude depth channel 3, lithology channel 4, logging interpretation porosity curve channel 5, and logging interpretation The high-quality reservoir segment 6 and the porosity color icon 7.

[0026] Based on the usage method of the above system, the specific steps are:

[0027] S1. Establish a comprehensive histogram of the target interval of a single well; first determine the single well required for reservoir comparison, first establish a comprehensive histogram of the target interval of one of the wells, and establish stratum 1 and electrical survey curves sequentially from left to right 2. Lithology track 4, well logging interpretation porosity curve track 5, and then import th...

Abstract

The invention discloses a system for utilizing logging porosity data to carry out reservoir correlation and prediction. The system comprises a stratum track, an electric logging curve track, an altitude depth track, a lithology track, well logging interpretation porosity curve track, a high-quality reservoir section of well logging interpretation and a porosity color icon. The invention also discloses an application method of the system for utilizing the logging porosity data to carry out the reservoir correlation and the prediction. According to the application method of the system for utilizing the logging porosity data to carry out the reservoir correlation and the prediction, which is provided by the invention, the distribution and section change features of the high-quality reservoircan be clearly and intuitively shown and the exploration success rate can be effectively improved; the prediction of the inter-well high-quality reservoir is realized to provide a very important technical support for selection and deployment of a well location target.

Description

technical field [0001] The invention relates to the field of oil and gas geological exploration in the petroleum industry, in particular to a system for carrying out reservoir comparison and prediction by using logging porosity data and a method for using the same. Background technique [0002] my country is rich in oil and gas resources. Oil and gas play an important role in my country's economic development. Oil and gas are generally buried deep underground. Oil and gas exploration needs to be carried out through oil and gas exploration technology, and then through oil and gas extraction, oil and gas can only be used after oil and gas are extracted. [0003] At present, the drawing methods of oil and gas reservoir correlation maps used in oil and gas exploration are all based on the logging interpretation results to carry out layer-to-layer correlation. The distribution details of high-quality reservoirs are limited, and the reservoir changes between wells cannot be effect...
