Research On The Control System Of Oil Extraction Joint Station Based On PLC

This thesis is focused on the Sulige gas field characteristic of permeability, low pressure, low-yield, using the horizontal well technology to develop the thin gas, to research the horizontal well completion and the segmented transformation integration technology. The aim is to improve development effect and recovery ratio.Domestic horizontal well completion and piecewise transformation integration technology is still in its infancy. A variety of difficulties and shortcomings is needed to overcome. According to rock mechanics, fluid flow mechanics theory and consider Sulige horizontal wells feature, establishing the mathematical model of horizontal well completion staged fracturing optimization, and solve this model, studying the staged fracturing for horizontal well completion optimization theory. And using a combination of mechanics, reservoir engineering, modern mathematics and modern computing technology, multi-disciplinary, combined with the Sulige gas field reservoir characteristics, Sulige gas field horizontal wells flow mathematical model, further in-depth study of horizontal wells gas-water percolation mechanism and the system of Sulige gas field horizontal wells percolation characteristics.Evaluation staged fracturing development effect of the horizontal well completion. Integrated to optimize the development mode, and determine the optimization technology of the horizontal well completion and staged fracturing transformation.
