Problems solved by technology

[0002] A hierarchical and cascaded method for evaluating the oiliness of channel sandbodies has been developed to solve the problems of shallow channel sand reservoirs with complex oil and gas enrichment rules, single oil and gas assessment methods, and poor integration of seismic and geology.
[0003] In recent years, the success rate of exploratory wells drilled for channel sand body reservoirs is less than 30%. On the one hand, it is due to the fact that with the continuous advancement of the exploration process,

Embodiment Construction

[0025] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.

[0026] like figure 1 as shown, figure 1 It is a flow chart of the method for evaluating the oiliness of river channel sand in the present invention.

[0027] In step 101, a joint analysis of structural background and fracture features is performed.

[0028] Starting from the analysis of the distribution characteristics of the discovered oil and gas accumulation belts for the entire sag, determine the reservoir-controlling effect of faults and structural ridges, and use advanced coherence technology to interpret layers and faults in detail, clarify the characteristics of structural development, and then select macroscopically. study zone. The process goes to step 102.

[0029] In step 102, analysis of reservoir-cap combination configuration an...

Abstract

The invention provides a river channel sand oiliness evaluation method comprising the steps as follows: step 1, making conjoint analysis of the structural setting and fracture features, and selecting a research zone; step 2, making reservoir-cap combined analysis in the selected research zone to determine the main oil-bearing series, and making fault activity conjoint analysis; step 3, characterizing the structural ridge in the determined main oil-bearing series to indicate the dominant path for oil and gas migration; step 4, applying a fluid test method under different lithological combination conditions; and step 5, classifying sand bodies and comprehensively evaluating the oiliness. According to the river channel sand oiliness evaluation method, the oiliness is evaluated scientifically and reasonably through comprehensive analysis of various factors, the multiplicity of solution is reduced, a favorable target is provided for well placement, and efficient offshore exploration is realized.

Description

technical field [0001] The invention relates to the technical field of oilfield development, in particular to a comprehensive evaluation method for the oiliness of channel sand bodies. Background technique [0002] A hierarchical and cascaded method for evaluating the oiliness of channel sandbodies in shallow channel sand reservoirs has been developed to solve the problems of complex oil and gas enrichment rules, single evaluation method for oil and gas properties, and weak combination of seismic and geology. [0003] In recent years, the success rate of exploratory wells drilled for channel sand body reservoirs is less than 30%. On the one hand, it is due to the fact that with the continuous advancement of the exploration process, the exploration direction and exploration targets have changed, that is, from the main part with structural background to the To the wing, look for lithological bodies with more complicated accumulation conditions; on the other hand, the oil and g...
