摘要:

泡排是目前长庆气田的主体排水采气工艺,部分泡沫到达地面管线后仍然未能消泡,需要辅助消泡剂以降低泡沫对污水处理系统造成的危害。由于液体消泡剂作用时间短、消泡效果差、自动化程度低,近年来长庆气田加大了固体消泡装置应用,但与之配套的固体消泡棒成本高、适用性差,导致消泡效果不明显,严重制约了工艺的推广应用。根据长庆气田水质特征,以二甲基硅油与气相SiO2颗粒为原料制得硅膏,并辅以固化剂蔗糖及乳化剂S?185,通过熔融反应,冷却后制成固体消泡剂DFS?1。采用Q/SY 17001-2016《泡沫排水采气用消泡剂技术规范》对其进行室内测试,消泡时间小于等于12.1 s,抑泡时间大于10 min,采用模拟地层水对比评价,各项性能参数均符合要求,可满足长庆气田现场应用需求。

Abstract:

Foam drainage gas recovery is the main drainage gas recovery process in Changqing gas field,some of the foam has not been defoamed after reaching the surface pipeline.Auxiliary defoaming agent is needed to reduce the damage of foam to the gathering and transportation system. Foam drainage gas recovery process is the main drainage gas recovery process in Changqing gas field at present. Some foam still fails to defoam after reaching the surface pipelines, so auxiliary defoaming agent is needed to reduce the damage caused by foam to the gathering and transportation system.Because of liquid defoamer has short action time,poor defoaming effect and low degree of automation,the application of solid defoaming device has been increased in Changqing gas field recently,but the supporting solid defoaming rod has high cost and poor applicability, which leads to the non?obvious defoaming effect and seriously restricts the popularization and application of the process.According to the water quality characteristics of Changqing gas field, dimethyl silicone oil and gaseous silica particles were used as raw materials to make silica paste, sucrose as curing agent and S?185 as emulsifier. After melting reaction, solid defoaming agent DFS?1 was produced after cooling.Q/SY 17001-2016 technical specification for defrosting agent for foam drainage gas recovery was adopted to test its performance. The defrosting time was 12.1 s and the bubble suppression time was longer than 10 min. The comparison test of simulated formation water shows that all the performance parameters meet the requirements, which can meet the field application requirements of Changqing gas field.

Key words: Defoaming agent, Silica, Foam drainage, Solid, Changqing gas field
