Xiliutongkou Regional Es₁^x Horizontal Well Development Adaptability And Production Process Optimization Research

This article through to have RaoYang sag at lixian county after slope nishiyanagi with mouth areas of horizontal well is analyzed and summarized,it is concluded that for horizontal well development of the reservoir geological characteristics,discusses the reasonable well pattern and water policy.Formulated on the basis of studying the applicability of design standard and method of horizontal well,optimization technology of horizontal well development policy.The main content of this study has four aspects: one is horizontal well geological applicability evaluation,including geological evaluation,design standard and method of horizontal well and horizontal well nishiyanagi with mouth for deployment of horizontal well block geological characteristics;Second,reservoir engineering applicability evaluation,including pattern,water injection policy and economic benefit evaluation;Three is the horizontal well development policy optimization technology,including the well type,well spacing,horizontal section length,fracturing fracture optimization research;Four is production technology research,including the way of well completion,perforation mode,production mode and the stimulation evaluation.For research purposes,the use of appropriate technology route,through nishiyanagi analysis of drilling horizontal well in mouth area summary for horizontal well development of the reservoir geological characteristics,summarizes the nishiyanagi with mouth area,the design method of the horizontal well optimized,establish standards for horizontal well design.Based on the research of the real drilling horizontal well,analyzes the applicability of the well pattern of horizontal well and water injection policy and economic evaluation.Works in horizontal well,on the basis of optimizing the development of concrete technology,select the appropriate production technology.Through study five know: it is a simple structure,stable sand body distribution,reservoir longitudinal small number of upper reservoir are the geological conditions of drilling horizontal well;From the drilled horizontal well mining effect,the good reservoir physical property of reservoir drilling horizontal well development effect is good.,poor physical property of oil,poor reservoir,most Wells in benefit edge;Three is for low permeability reservoirs,must advance with water,for conventional permeability of reservoir,the water injection timing requirements is not high;Four is USES the casing cementing completion,perforation,conventional process production is relatively appropriate;Fifth,acidification and fracturing is an effective method for horizontal well production.
