Delicate Reservoir Description And Developent Adjustment Method For X37 Fault Block

At present,Most of the domestic oil fields has been in the later stage with the continuous production of crude oil and the influence of such factors as pressure changes and water content,the phenomenon such as injection-production doesn't work and high moisture content seriously affect the ultimate recovery of oil field.To meet the needs of the oilfield development and improve the development effect,it is necessary to conduct comprehensive geo logical research,fully implement the tectonic situation,describing the space of reservoir physical properties change rule and distribution state,and then put forward the development adjustment measures.In this paper,X37 fault block oil reservoir is taken as the research object to carry out fault block of fine reservoir description.Using fine reservoir description as the main research method.On the basis of a single sand body,I used a variety of disciplines theory and technology,such as modern stratigraphy,sedimentary facies,reservoir sand body description,phased reservoir modeling and reservoir potential analysis techniques.Through the analysis of logging data contrast,in the small layers divide and single sand body.To describe sedimentary microfacies distribution by fine dividing into small layers.Simulating porosity permeability and other physical parameters in formation distribution with 3D geological model.Through the analysis of historical data find out the problems existing in the development process.Through a series of basic data,to improve the leve of recognition of reservoir,to find out spatial distribution of sand and water-oil with utilizing the means such as reservoir,geological.O n the basis of fine reservoir description to evaluate the development effect,research of remaining oil distribution law with the 3D geological modeling.The comprehensive analysis about X37 fault block oil reservoir potential in order to put forward a reasonable development adjustment method.
