A data link method for oil and gas reservoir research and decision-making

Abstract

A data chain method for research and decision-making of an oil and gas reservoir belongs to the technical field of comprehensive research and decision-making of oil and gas reservoirs by applying modern information technologies. An oil and gas reservoir data chain comprises a four-layer structure, that is, metadata, a dataset, chain junctions and a data chain. The metadata defines a logical relationship, is used for describing a data resource object and performing localization management, and realizes transmission from the research results of data items to the dataset; the dataset packs the metadata into a data unit with a transmissible data chain; the data unit has an independent business meaning, at the same time, and is a basic unit for right control and processing in the data chain; the dataset can be rapidly pushed to all research posts (the chain junctions), and realizes the unification of a business flow and a data flow; the data chain connects the chain junctions into an information transfer passage according to the applying theme, gives corresponding constraint information, realizes integrated application of results of different posts, and has the characteristics of real-time performance and traceability.

Description

technical field [0001] The invention relates to a data link method for oil and gas reservoir research and decision-making, and belongs to the technical field of applying modern information technology to serve oil and gas reservoir comprehensive research and decision-making. Background technique [0002] Oil and gas reservoirs are the basic units of oil and gas accumulation on the earth's crust, and are highly complex dynamical systems. The understanding of oil and gas reservoirs is restricted by time, space scales and technical means, and has significant multiple solutions and uncertainties. Therefore, oil and gas reservoir research requires systematic and comprehensive thinking, multidisciplinary methods and technologies, and a collaborative and permeable working method. In the last century abroad, the comprehensive research concept of oil and gas reservoir integration was proposed, and good results have been achieved in international oil companies such as Shell, Chevron, a...

Problems solved by technology

The construction and use mode that separates data flow from business flow leads to low data organization efficiency and difficulty in ensuring data timeliness and quality

[0004] Second, the software application is "advanced in some parts, backward in the whole"

Domestic oil and gas fields have introduced a variety of domestic and foreign large-scale professional software such as seismic processing and interpretation, logging evaluation, geological research, geological modeling, and numerical simulation in various professional fields of exploration and development. Unified, software application lacks a unified interactive platform, but management is still in the traditional research mode of "small workshops", resulting in low application efficiency of some large-scale software function modules, and the difficulty of transferring and sharing results between different software is difficult and impossible Integrated Collaborative Research
