Embodiment

[0042] Please refer to figure 1 , with reference to Figure 2 to Figure 6 , this embodiment provides a shale exploration system, which includes a shale lithofacies plane distribution compilation method, the shale lithofacies plane distribution compilation method is used to determine the specific lithofacies distribution, and finally obtain a lithofacies plane distribution map, And then guide the exploration and development of shale oil and gas.

[0043] The method for compiling the plane distribution of shale lithofacies includes the following specific steps:

[0044] a. Collect shale samples from cores and outcrop profiles at different points in the study area, conduct X-ray diffraction analysis and organic matter content (TOC) analysis, and obtain the mineral composition and organic matter content (TOC) data of the samples;

[0045] b. Use the TOC content of different wells and outcrop samples on the plane to compile and draw the TOC plane contour map;

[0046] c. Use the...

Abstract

The invention provides a shale rock-phase plane distribution compilation method and a shale exploration system, which belong to the technical field of petroleum exploration. The method comprises the following steps: using a mineral component content of a shale sample, and performing compilation of a 3-end-mumber graph of the silicon mineral content, carbonate mineral content and the clay mineral content; using the mineral component content and the organic matter content, performing compilation of a plane distribution map of an organic matter, silicon mineral, clay mineral and carbonate mineral; according to the 3-end-mumber graph and the plane distribution map of the organic matter, the silicon mineral, the clay mineral and carbonate mineral, dividing the rock phase of the shale; performing superposition intersection on an organic matter plane distribution map, a silicon mineral plane distribution map, a clay mineral plane distribution map, and a carbonate plane distribution map, and determining the shale rock-phase plane distribution according to a rock-phase dividing standard. The shale exploration system has the above shale rock-phase plane distribution compilation method, whichis simple and easy to use and realizes quantitative operation.

Description

technical field [0001] The invention relates to the technical field of petroleum exploration and development, in particular to a method for compiling plane distribution of shale lithofacies and a shale exploration system. Background technique [0002] Shale gas is currently the focus of unconventional oil and gas exploration and development. With the deepening of research, more and more scholars have found that the characterization and research of shale lithofacies play an important role in finding the "sweet spots" of shale gas. The planar distribution of shale lithofacies directly determines the search for favorable lithofacies targets. Therefore, plane compilation of shale lithofacies plays an important role in shale gas exploration. [0003] Many scholars have done a lot of research on shale lithofacies, and some patents are related to shale lithofacies research, but most of the research mainly focuses on how to divide lithofacies, describe lithofacies and predict litho...
