Study On Classification And Effect Evaluation Of Horizontal Wells In Luliang Oilfield

In this thesis the research object is126developed horizontal of9wellblock anteclise, Xinjiang oilfield land cretaceous wall of Hutubi river group40lenticular low amplitude, high permeability, thin layer edge and bottom water reservoir.In horizontal well water cut rising fast, rapid production decline and development problems such as difficult control, is the main purpose of this paper of carry out the horizontal classification, mining effect evaluation research and development characteristics.Horizontal wells technology at home and abroad and the related theoretical research is presented in this paper, based on the combination of horizontal Wells in prophase anteclise geology and development of numerical simulation and research results, application of geological, logging, reservoir engineering and numerical simulation methods such as theory, geology, logging and production performance, the combination of fine dissecting typical lens side bottom water reservoir, deepen understanding reservoir distribution, low resistivity zone and edge-bottom water distribution of oil-water distribution characteristics and reservoir oiliness, flow characteristics of oil and water distribution and the main classification elements, with horizontal reservoir thickness and oil content, physical factors for attributes elements such as, viscosity, and better solve the problem of horizontal classification.And applied to numerical simulation and the same kind of horizontal Wells and vertical Wells contrast, similar horizontal contrast, such as different types of horizontal contrast analogy method, the comprehensive understanding of horizontal type, development characteristics and effectBased on the classification of horizontal Wells, from the horizontal factors, geological and mining factors in three aspects, studies the influence factors of horizontal well development effeet.For reservoir exploration, provides theory basis for horizontal well governance, etc, and has reference to the similar reservoir horizontal well development research.
