Xing North Zone Thin And Poor Reservoir Effective Use Of Technology Research And Application

Daqing Changyuan area Xingnorth zone has entered the high water-the main target of waterflooding has been transformed into high-permeability layer thin and poor reservoirs, improve development and adjustment has become thin and poor reservoir to improve the water flooding effect the focus of the work. Currently microscopic pore structure characteristics of thin and poor reservoir, porosity and permeability, percolation mechanism and macro development technology boundaries are not clear, and strengthen the system of injection and production methods are not clear, the need for further study. The purpose of this thesis is to provide the technical basis for the development of adjustment Xingnorth Zone thin and poor reservoir work, to provide technical support for the development and effective use of such oil to ensure smooth and efficient production Xingnorth Zone succeed.In this article, the main problems with high water-Apricot North Zone thin and poor reservoir exists to carry out plans to strengthen thin and poor reservoir through laboratory experiments, thin and poor reservoir percolation theory and technical boundaries of research and field trials, thin and poor reservoir explore NOTE mining systems approach to high water-Potential water flooding has important strategic significance.The main contents of this paper to study:First, to carry out a-three districts in eastern apricot, apricot six districts in the eastern block of the field test area geology fine anatomical study thin and poor reservoir sedimentary characteristics, distribution of reserves; the second is to carry out laboratory experiments thin and poor reservoir a study on thin and poor reservoir pore structure characteristics, relative permeability curves, lithology; third, to conduct thin and poor reservoir percolation theory and technical boundaries of research, study thin and poor reservoir flow characteristics and percolation mechanism to determine the difference between the thin reservoir layer flow mode; study thin and poor reservoir reservoir technology boundaries, including reasonable pressure systems, fluid productivity index, and proposes to strengthen thin and poor reservoir injection and production systems approach; Fourth, the experimental study of the field, through the implementation of reduced oil wells number ratio, thin and poor narrowed from reservoir wells, improve relationship between injection single sand body, different note like strengthening measures thin & poor reservoir injection-production system, the results of validation studies, research thin and poor reservoir performance characteristics, and based on the scene The test results, improve thin and poor reservoir reasonable technical limits..
