Description
Technical field
The present invention is about energy exploration technical field, especially with regard to the exploration engineering of routine and unconventional oil and gas, specifically
Say be maceral composition in a kind of rock quantitative approach and system.
Background technique
Identifiable organic principle is known as maceral under an optical microscope, they be mainly derived from extinct plants and animal tissue,
The remnants and its thermal evolution product of organ.The composition of maceral has established the material base of oil-gas generation in hydrocarbon source rock, determines
The property and quantity for generating hydro carbons, are the important Geochemical Parameters of petroleum exploration domain.In general, being seen using optical microscopy
The structure and optical signature for examining deposition organic matter, establish the appraisal mark of each maceral, and then micro- in quantitative deposition object
Group is grouped as.
Although the classification system and classification schemes of maceral have differences, the development of decades is undergone, the world has
Machine rock educational circles is in agreement scheme with regard to the basic classification system of maceral.Based on this classification schemes, maceral
Quantitative statistics be achieved.In general, the volume (DOM) for the hydrocarbon source rock dispersed organic matter that maceral quantitative statistics obtain and total
Such relational expression: TOC=DOM × 0.5 × n (n value 60~90%) (Smyth et is generally conformed between organic carbon (TOC)
al.,1984).Similar TOC, this parameter can be used for abundance of organic matter in quantitatively characterizing hydrocarbon source rock.It is especially noticeable

Rock inclines oil gas, provides basic data for oil-gas exploration.
It can be seen that maceral observation is one " seeing is believing " oil and gas geochemistry analysis and testing technology, determine
Amount is a very important basic research work in petroleum and gas geology and exploration.Maceral composition is quantitative common in the prior art
Method specifically includes that
(1) eye estimating method.Eye estimating method is researcher according to experience, visually estimates that each maceral accounts for the total volume of rock
Ratio.The technology depends on the experience of researcher, has stronger subjectivity, and error is larger, and repeatability is lower.
(2) several methods.Several methods are with fixed point away from mobile with line-spacing, under statistics eyepiece crosshair intersection point micro- group
Point, generally at least count 500 points.In general, with maximum particle diameter (dmax) half as point away from and line-spacing: d=1/
2dmax.This kind of method larger workload, it is difficult to count the content of tiny or Filamentous organic matter, repeatability is general, and there are one
Determine error.
