摘要

水平段长度直接影响水平井的控制储量、单井产量和钻井成本等指标，是决定水平井开发效果的关键因素。针对靖边气田碳酸盐岩气藏的低渗、薄层、强非均质特点，在水电模拟实验研究气井渗流机理的基础上，综合数值模拟分析、经济评价和现场应用效果优化水平段长度。研究表明：水平井泄气面积近似椭圆，水平段跟端和趾端为主要渗流单元。当水平段长度大于1 000m时水平井稳产5年配产可以达到直井的3倍以上|当水平段长度为3 000m时，经济效益最优|综合考虑产量目标、效益目标和实钻效果确定马五₁₊₂气藏水平井合理水平段长度为1 000～1 500m。该研究成果已经用于靖边气田产能建设中，也可为其他类似气田水平井设计提供借鉴。

Abstract

The length of the horizontal section of a horizontal well has a direct effect on controlled reserves,single well output,drilling cost and other indicators.It is a key factor to determe the development performance.For carbonate reservoir with low permeability,thin layer and strong heterogeneity in the Jingbian Gas Field,based on the hydro-electrical analogy on gas percolation mechanism,to optimize the length of horizontal section,a comprehensive analysis has been carried out,including numerical simulation,economic evaluation and field application.The evaluation results show that a horizontal well gas drainage area is approximately elliptic,the major percolation parts are on the heel end and toe end.When the horizontal length is greater than 1000m,after 5-year plateau the production allocation can reach three times more than a vertical well|when the length is 3 000m,the economic benefit is optimal|for the targets of output and efficiency,as well as drilling result,it was determined that the reasonable horizontal length of well Ma5₁₊₂ is 1 000m to 1 500m.The research results have been applied in the production capacity construction of Jingbian Gas Field,and it provides a reference for other similar horizontal gas wells design.
