Prediction Of The Dolomite Reservoir And Favorable Targt In The Upper Part Of The Sha-3 Member Of Eogene System In Binnan-Lijin Fault Belt

Binnan Lijin fault belt sand three dolomite fracture special lithologic reservoir exploration and development due to reservoir prediction technology and cracks of the techniques described in the control has not been effective development.In view of the present mining situation and the dolomite reservoir prediction is very difficult,of Binnan Lijin fault with dolomite fractured reservoir are studied.Describes the development and distribution of dolomite reservoir in this area,Discusses the dolomite reservoir space mainly by dissolution pores and fractures,reservoir space is small,poor permeability,belonging to the low porosity and low permeability reservoirs.Take the logging curve reconstruction,to judge the dolomite,and find out the development characteristics of dolomite reservoir.Based on the detailed stratigraphic correlation,syntheticseismogram calibration using multi well,realize the fine structure interpretation of dolomite,According to the characteristics of dolomite reservoir,from various inversion methods to chose suitable inversion method,the implementation of logging constrained inversion,dolomite reservoir layer plane distribution characteristics for the implementation of.The multi-scale pixel imaging technology,multi-scale and multi-attribute(curvature and coherence),multi-scale and multi-scale frequency dividing coherent body and high-precision curvature body are integrated into consideration of the fracture prediction.Describes the rules of reservoir fracture prediction of dolomite,dolomite reservoir fracture development and the development direction of the main enrichment zone.Reservoir prediction layer crack fracture development belt mainly dolomite along the top interface of present-day tectonic of the second step(semi deep lake)distribution,crack and fracture systems associated.The upper part of the upper middle and lower part of the upper part of the sand three is in the development,and the middle and lower part is relatively poor.High yield oil gas wells are usually associated with moderate scale meshfractures,while the large scale fractures and faults may play a destructive role in oil and gas production.By studying the various properties of structural position,sedimentary environment,fracture distribution and seismic inversion,the combination of hydrocarbon accumulation conditions and main controlling factors,the implementation of comprehensive evaluation,and select the favorable target.
