A Study Of The Karlov-Oxfordian Sedimentary Facies In The Eastern Part Of The Right Bank Of The Amu Darya River In Turkmenistan

The thesis block is located in the eastern part of the right bank of the Amu Darya in Turkmenistan,the subject Jurassic Upper Jurassic Callovian-Oxfordian carbonate formations,XVhp,XVa1,XVa2 and other layers of the block is the main oil and gas reservoirs.Althoufh many wells have been put into operation,but sedimentary microfacies,characteristics and distribution situation is not very clear,so the reservoir sedimentary characteristics of the study area is necessary to carry out detailed studies.Preferably the favorable reservoir facies,provide the basis for the exploration deployment.In this paper,based on the sedimentary petrology,multidisciplinary carbonate reservoir geology,sequence stratigraphy as the theoretical guidance,and combined with logging,cores,flakes,geochemical analysis experiments and seismic data from the 10 welldrilling,sedimentary facies spatial distribution characteristics and distribution of favorable reservoir facies belts carried out a detailed study.Research by the target horizon rock thin section,paleontological features,logging facies,seismic facies analysis,combined with previous research,the study confirmed that the block is slow ramp carbonate platform sedimentary facies,the target layer bit sedimentary facies mainly slope facies.By single well facies analysis,and compared well tie profile,drawing even well sectional comparison chart,clear the area of sedimentary facies study the spatial distribution characteristics,structural factors Finally,experiments and other mercury porosity and permeability data to determine the favorable reservoir facies distribution characteristics and draw favorable reservoir facies distribution map,Provide the basis for the exploration deployment.
