摘要
老井侧钻水平井是挖掘油气田剩余可采储量潜力,提高油气藏采收率的有效方法之一。目前该技术已成为国内各老油田开发后期有效的增产稳产手段,不仅避免了钻新井或加密井的重复建设投资,而且能有效降低开发成本,完善开发井网,提高单井产量和储量动用程度,具有广阔的应用前景。通过对老井侧钻水平井开发技术的研究,结合苏里格气田致密砂岩气藏地质特征、开发现状以及剩余气分布,论述了该技术在苏里格气田开发的应用情况及效果,对今后老井侧钻水平井技术在苏里格气田的规模应用起到一定的指导作用。
The application of sidetracking horizontal technology in old wells, which is one of the effective methods for the potential of mining the remaining recoverable reserves and improving recovery in oil and gas fields. At present, the technology has become the domestic effective means to increase and stabilize production in later stage of development in old oil and gas fields, which has a broad application prospect, and it not only avoids the repeated construction investment of drilling new wells and infill wells but also reduces development costs, perfects well spacing, improves the single well production and reserves producing level. Based on the study of sidetracking horizontal technology in old wells, this paper discusses the application and effect of the technology in Sulige gas field development, which combines the geological characteristics of tight sandstone gas reservoir and the remaining gas distribution and development in Sulige gas field. It will play a guiding role of the large-scale use of sidetracking horizontal technology in old wells in Sulige gas field.
