Description
Technical field
The present invention relates to shale oil Exploration Domain, especially relate to a kind of lacustrine shale oil dessert Dominated Factors evaluation methodology.
Background technology
Shale oil dessert Dominated Factors evaluation methodology is the key technology of shale exploration activity.Shale oil-gas exploration is just opened in China
Begin to start to walk, many guardian techniques also do not solve, shale oil dessert Dominated Factors evaluation methodology is one of.Therefore,
Shale oil dessert Dominated Factors evaluation methodology is significant for shale exploration activity.
For a long time, it is all that mud shale to be studied as hydrocarbon source rock or cap rock in classical petroleum geology theory, but
Growth with energy demand and theoretical, technology progress, rich organic matter mud shale becomes oil exploration and exploitation now
Important goal.Because search time is short, people recognize unclear to shale oil dessert Dominated Factors.Only true both at home and abroad at present
8 key elements of shale oil enrichment are determined：Shale thickness, shale buried depth, abundance of organic matter, maturity of organic matter, shale ore
Thing composition, shale physical property, shale mechanical property, oil-gas possibility.Domestic with these key elements, shale oil evaluated and surveyed
Visit, but exploration effects are unsatisfactory, illustrate that the major control factors of shale oil enrichment also do not recognize clear.For this we
Invent a kind of new lacustrine shale oil dessert Dominated Factors evaluation methodology, solve above technical problem.
Content of the invention
It is an object of the invention to provide one kind is dissected using mathematical statisticss, type area and generation and expulsion modeling experiment combines really
The method determining lacustrine shale oil dessert Dominated Factors.
The purpose of the present invention can be achieved by the following technical measures：Lacustrine shale oil dessert Dominated Factors evaluation methodology, should
Lacustrine shale oil dessert Dominated Factors evaluation methodology includes：Step 1, will according to preserve lithology and the preservation space of shale oil gas
Shale oil type is divided into mud shale type and sandwich type two types；Step 2, is dissected by mathematical statisticss, typical case and raw row
Mud shale type, sandwich type shale oil dessert Dominated Factors are analyzed by the method that hydrocarbon simulation experiment combines；Step 3,
Determine the favourable enrichment region of shale oil according to shale oil dessert Dominated Factors.
The purpose of the present invention also can be achieved by the following technical measures：
In step 2, determine that mud shale type shale oil dessert Dominated Factors are：Rich organic matter lamellar shale, abnormal pressure,
Mobility, crack or microcrack.
In step 2, for mud shale type, rich organic matter lamellar shale is the basis of shale oil enrichment, and abnormal pressure is
Shale oil is enriched with the essential condition of output, and mobility is the prerequisite of the favourable output of shale oil, and crack or microcrack are pages
Shale oil is enriched with the key of output.
In step 2, determine that sandwich type shale oil dessert Dominated Factors are valid source rock, abnormal pressure, Reservoir.
In step 2, for sandwich type shale, valid source rock is the basis of shale oil enrichment, and abnormal pressure is enrichment output
Key factor, Reservoir be shale oil be enriched with output key.
Lacustrine shale oil dessert Dominated Factors evaluation methodology in the present invention, is related to apply mathematical statisticss, type area to dissect
With methods such as generation and expulsion modeling experiments, determine shale oil dessert Dominated Factors.The method has been determined former shale oil dessert master control
The unclear problem of factor understanding, whole method is workable, simultaneously smooth for continental faulted basins lacustrine shale exploration activity
Laid a good foundation.It is favourable that the present invention provides a kind of effectively determination shale oil dessert from the angle of the dynamic enrichment of shale oil
The method in area, is that continental faulted basins lacustrine shale exploration activity is smoothed out laying a good foundation.

Specific embodiment
Above and other objects, features and advantages for enabling the present invention become apparent, cited below particularly go out preferred embodiment,
And coordinate shown in accompanying drawing, it is described in detail below.
As shown in figure 1, Fig. 1 is the flow chart of the lacustrine shale oil dessert Dominated Factors evaluation methodology of the present invention.
The shale oil type of Jiyang depression is divided into mud page according to preserve lithology and the preservation space of shale oil gas by step 101
Lithotype and sandwich type two types.As shown in Fig. 2 the shale oil type of Jiyang depression is divided into mud shale type and sandwich type two
Type.
Step 102, is dissected by mathematical statisticss, typical case and the generation and expulsion modeling method that combines of experiment, to mud shale type,
Sandwich type shale oil dessert Dominated Factors are analyzed.Determine that mud shale type shale oil dessert Dominated Factors are：Rich organic
Lamellar shale, abnormal pressure, mobility, (micro-) crack；In Fig. 3, Fig. 4, raw, simulating hydrocarbons expulsion experiment shows,
Oil generating ratio, oil extraction rate：Lamellar>Stratiform>Block；In Figure 5, pressure compartments case edge pressure transition section is most beneficial for page
Shale oil is enriched with；In figure 6, S1/TOC>10%, S1>2mg/g, viscosity<10mPa.S is conducive to the enrichment of shale oil；In Fig. 7
In, the fuel-displaced well section of shale oil is mainly distributed on fracture belt and the turning point (Fractured Zone) of construction；Sandwich type shale oil
" dessert " Dominated Factors are mainly valid source rock, abnormal pressure, Reservoir, as shown in Figure 8.Flow process enters into step 103.
Step 103, determines the favourable enrichment region of shale oil according to shale oil dessert Dominated Factors.In one embodiment, according to not
Same type shale oil dessert Dominated Factors, determine the favourable enrichment region of shale oil in Dongying, Zhanhua depression.
The foregoing is only presently preferred embodiments of the present invention, be not used to limit the scope of the claims of the present invention, other are with this
The equivalence changes of the patent spirit of invention, all should all belong to the scope of the claims of the present invention.
