气井排液采气方式优选及排液采气井安全评价 

在油气田的开采过程中,随着气藏压力和天然气流动速度的逐步降低,气藏中产出水或凝析液不能随天然气携带出井筒,从而滞留在井筒中,形成“气井积液”;气井积液严重地影响了天然气产量,并导致油田经济效益的下滑,因此必须采取排液采气措施,来增加气井乃至气田的产量。但排液采气方式措施多种多样,并各有优缺点,而且不同的工艺...

致密油藏压裂井生产动态分析研究 

在进行低渗透油藏生产资料分析中,所面临的困难是其渗流会受到井筒储存效应的影响,会造成渗流过程持续很长时间。因此,计算最终采收率(EUR)以及储层性质,如裂缝半长、渗透率、排水面积和裂缝导流能力都是具有一定难度。本文选取新疆某油田作为例子进行研究,该油田为致密砂岩储层,本文通过选定模型和RTA软件的水平井应用分析功能分析...

降水井与仰斜排水管联合排水措施在危险边坡治理中的应用研究 

边坡因排水措施不足,雨季地下水头上升较快,导致边坡安全系数过低,在各种不利因素条件综合作用下,甚至会发生失稳破坏,因而为这类边坡增设降排水措施十分必要。论文以坝光收费站边坡工程为背景,针对既有边坡排水措施的缺点,提出一种“降水井+仰斜排水管”的联合降排水措施,具有可操作性强、免维护、排水效果好等优点,围绕这一“井管”结...
