摘　　要：苏里格气田是典型的低压、低渗、低丰度岩性气藏,具有储层非均质性强、砂体横向变化快的地质特点。苏20区块位于苏里格气田中区,随着区块开发程度的不断深入,目前面临着地层压力下降、产量降低、低产低效井井数大幅度增加等困难,本文从开发老井目前产层生产潜力评价、未动用层生产潜力评价、井间干扰评价、层间干扰评价四个方面进行详细阐述,分析总结苏20区块老井补层成功经验,提出苏里格老井补层地质选井技术思路和方法,为苏里格气田开发中后期老井稳产增产提供有利保障。Sulige gas field is a typical low pressure, low permeability, low abundance lithologic gas reservoir with strong reservoir heterogeneity. Su-20 block is located in central Sulige Gasfield.With deepening of the degree of block development, some difficulties are faced, such as formation pressure drop, low yield and so on. In this article, old well layer production potential evaluation, unused production potential evaluation, evaluation of interwell interference, interlayer interference evaluation were carried out, analysis summary old well in Su-20 block fill layer of successful experience, put forward old well in a layer geological technology thought and method of selecting well, f for the middle and old Wells yield increase of Sulige Gas Field development guarantee.
