摘要： Wellhead apparatus as set forth for installation on a producing gas well which has a certain measure of condensate therein. The device includes an alignment tube which is precisely constructed for easy transition from the tubing string. That connects to a master valve which connects to a tee thereabove. A lateral flow line connected with a gas valve regulates gas produced from the well. The master valve is just below the tee, and the tee extends upwardly into a lubricator extension tube. The two are connected together by a lubricator extension union sub which utilizes a lock nut engaging a pair of matching shoulders. A method of timed production is also disclosed.

摘要： Wellhead production apparatus is set forth. It is adapted to be connected to a cased well having a production tubing string therein. It cooperates with a plunger traveling freely in the production tubing string. The wellhead apparatus connects typically through a flange at the wellhead, a master valve, a vertically extending tube which connects into and comprises a tee. The equipment extends thereabove so that the plunger can travel above the tee and is rebounded for reciprocation. The tee is formed of two cylindrical members which are arranged concentric of one another to define an annular flow space therebetween. The annular flow space being connected through an opening into a lateral production flow line. The tee thus cannot be blinded by stalling the plunger even with the lateral flow line.
摘要翻译：井口生产设备列出。其适于连接到其中具有生产油管柱的套管井。它与在生产油管柱中自由行进的柱塞配合。井口设备通常通过井口的法兰连接，主阀，连接到并包括发球台的垂直延伸的管。设备在其上方延伸，使得柱塞可以在三通上方行进并且反弹以进行往复运动。发球台由两个圆柱形构件形成，它们彼此同心地设置，以在它们之间形成环形流动空间。环形流动空间通过开口连接到横向生产流动管线中。因此，即使使用横向流动管线，三通也不能使柱塞失速。
