可调式井口连接模拟平台的研制与应用

Development of Adjustable Wellhead Simulation Platform and Its Application

龙王庙组气藏气井须安装井口泄压和放喷管线。为解决安装过程中油套管连接和技表套管连接难以现场加工油管丝扣短节,方井内油管丝扣连接难度大,现场安装时间长、效率低的问题,设计制作一种可调式井口连接模拟平台,根据现场测量数据进行室内加工实现"工厂化"预制、"集成化"安装、"标准化"建设。在介绍可调式井口连接模拟平台的原理基础上,从平台结构、制作方法、平台参数3方面详细阐述了模拟平台的设计制作流程。同时,在平台上模拟出装置中生产节流阀与套管阀、技术套管阀与表层套管阀的相对空间位置,将生产节流阀和套管阀相连、技术套管阀和表层套管阀相连并在现场安装应用,以缩短施工周期并提高施工标准和效率。

In gas reservoirs of Longwangmiao Formation, pressure relief and blowout pipeline should be installed at wellhead.But during this installation, thread nipples cannot been manufactured on the spot. Moreover, it's difficult to connect these nipples,resulting in some problems of long installation time and low efficiency. So, a simulation platform of adjustable wellhead was developed. It can finish an indoor process, and realize the factory prefabrication, integration installation, and standardized construction.This paper illustrates the platform laws, and the flow process in terms of platform structure, development method, and platform parameter. In addition, Though this platform, the locations of throttle valve, casing valve, and technical casing valve and surface casing valve are simulated. One connection of both throttle and casing valves and another connection of both technical and surface casing valves are installed on the spot. Consequently, operation period shortens and working efficiency increases.
