Abstract

The invention provides a reservoir physical property evaluation method and device based on a triangular evaluation plate, and the method comprises the steps: dividing minerals in a rock core into three types according to the properties of parent rock in a rock core source region and a mechanical differentiation principle, and enabling the three types of minerals to respectively correspond to threevertexes of a triangular evaluation plate, wherein the three types of minerals comprise carbonate minerals, skeleton minerals and clay minerals; according to the contents of the three types of minerals and rock core physical property parameters, carrying out content region division on the triangular evaluation plate; and evaluating the physical properties of a reservoir to be evaluated accordingto the content region division. The invention can provide the method and the device for quickly and visually evaluating the physical property of a tight reservoir.

Description

technical field [0001] The invention relates to the field of petroleum exploration, in particular to a reservoir physical property evaluation technology, in particular to a reservoir physical property evaluation method and device based on a triangular evaluation chart. Background technique [0002] With the deepening of oil and gas exploration, the exploration technology of conventional sandstone reservoirs has become very mature, while the conventional sandstone exploration targets are becoming rarer and rarer. At the same time, the proportion of unconventional reservoir targets such as tight sandstone and shale is increasing, and their importance in oil and gas exploration is also becoming more and more significant. my country has successively made breakthroughs in the exploration of tight sandstone / shale in Sichuan and the Junggar Basin, especially the discovery of 1 billion tons of predicted tight sandstone (shale) reserves in the Lucaogou Formation in the Jimsar Sag of ...
