针对靖边气田年年开采,井筒积液日趋严重以致影响生产的情况,为排清气井井筒积液和方便工艺实施,在现场泡排剂试验及室内评价的基础上,编制出泡排采气工艺软件。首先,选择LabVIEW作为软件编制平台,确定软件的5项主要功能,设计出功能实现的相关程序流程:然后,用现场数据验证和筛选理论计算方法:优选Orkiszenski法判断井筒流态,王毅忠模型预测临界携液流速、流量,统计热力学法预测水合物生成,依据室内实验结果确定起、消泡剂用量,计算气-液混合物流经时间以确定合理消泡时间;最后,用两口产水气井做试验,结果表明:1#井日均产水量增加1.88m~3,日均产气量增加3780m~3;2#井日均产水量增加4.0m~3,日均产气量增加952 m~3。在软件指导下的泡排试验排出了井筒积液,效果良好,说明该软件对靖边气田产水气井的泡排生产,既好用,又理论联系实践。
In view of the annual mining of Jingbian gas field, the wellbore fluid is becoming more and more serious, which will affect the production. In order to conduct the wellbore effusion and facilitate the process implementation in the gas field, based on the field test of foam-releasing agent and indoor evaluation, Process software. First of all, we choose LabVIEW as the platform of software compilation, and determine the five main functions of the software to design the program flow of the function realization. Then, using the field data verification and screening theoretical calculation methods: Orkiszenski method is preferred to determine the wellbore fluid flow, Carrying liquid flow rate, flow rate, statistical thermodynamic method to predict the formation of hydrate, according to the indoor experimental results to determine the defoamer dosage, calculate the gas-liquid mixture through the time to determine the reasonable defoaming time; Finally, The results showed that daily average water production increased by 1.88m ~ 3 and average daily gas production increased by 3780m ~ 3. Average daily water production increased by 4.0m ~ 3 and average daily gas production increased by 952m ~ 3. Bubble discharge test under the guidance of the software discharged the wellbore effluent with good results, indicating that the software is good for both use and production of bubble production in Jingbian Gas Field.
