苏里格气田苏54区块气井控水配套技术研究

Study on Water Matching Technology of Gas Well in Su 54 Block of Sulige Gas Field

苏里格气田气井产液主要有7种类型:返排工作液、凝析水、储层内层窜水、原生层内水、次生层内水、套管外水窜、边水。在单井施工过程中,不同的工序采用不同的控水配套技术可以有效的防止气井产液。主要得气井控水技术有:井位井型优选、阵列感应测井识别气水层、物理下沉剂控水、气举阀助排压裂液。

There are 7 types of gas well production in Sulige gas field ： flowback fluid, condensate water, reservoir water channeling, primary layer water, secondary layer water, casing water channeling and side water. During the construction of a single well, different water control techniques are adopted in different processes to effectively prevent gas production. The main gas water control technology： location selection, type of array induction logging identification of gas layer, physical control of sinking agent water, gas lift valve help fracturing fluid.
