Problems solved by technology

This method is highly applicable to the regional stratigraphic correlation with the basin as the unit, but it is difficult to grasp the fine local stratigraphic correlation of smaller units, so it has not been widely used in exploration and production

Embodiment Construction

[0055] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention. It should be noted that, as long as there is no conflict, each embodiment and each feature in each embodiment of the present invention can be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.

[0056] The technical problem to be solved by the present invention is that the prior art lacks a stratum correlation method capable of organically combining the isolithological correlation method and the isochronic correlation method. In order to solve the above-mentioned technical problems, an embodiment of the present invention provides a stratigraphic correlation method for oil-gas-bearing basins.

Abstract

The invention discloses a stratigraphic correlation method and a system for a petroliferous basin. The method comprises the steps of dividing a petroliferous basin into a plurality of deposition systems; conducting the stratigraphic correlation successively for each deposition system based on the isolithology correlation method, and also conducting the stratigraphic correlation for the deposition system based on the isochronous correlation method so as to obtain an isochronous-sequence stratigraphic framework of the deposition system; based on the isochronous-sequence stratigraphic frameworks of all the deposition systems, obtaining a comprehensive-sequence stratigraphic framework. According to the invention, the novel stratigraphic correlation technique with each deposition system as a unit is adopted. Different stratigraphic correlation methods are adopted for the same deposition system in the basin and different deposition systems in the basin. Meanwhile, the isolithology correlation of the traditional stratigraphy and the isochronous correlation of the sequence stratigraphy are combined for comprehensive analysis. Therefore, the stratigraphic correlation problem in the same deposition system and the stratigraphic correlation problem among different deposition systems can be effectively solved. As a result, exploration errors caused by stratigraphic correlation faults can be avoided.

Description

technical field [0001] The invention relates to the technical field of petroleum exploration and development research, in particular to a stratum correlation method for oil-gas basins and a stratum correlation system for oil-gas basins. Background technique [0002] Stratigraphic correlation is an important basis for oil and gas exploration. Traditional stratigraphic correlation is an iso-lithological correlation with the unit as a unit. Isolithological correlation mainly uses the similarity analysis of lithology, color, thickness, content (paleontology, various minerals, etc.) between different drillings, or between drillings and field outcrops, to determine the comparison between them relation. This method works well for small-scale interwell correlations within the same provenance, but it is obviously blind for regional stratigraphic correlations between different sedimentary systems in the basin. [0003] In 1988, Americans such as P.R.Vail publicly published the theo...
