INTRODUCTION

Chemical medicament injection valve assembly includes chemical valve and fixed chemical injection joint, which is a wellbore equipment for controlling chemical medicament into tubing. Fixed injection valve is attached to fixed nipple before running in wellbore. A control line is connected to chemical valve and wellhead. Chemical medicament is injected into the production string by the surface chemical injection pump through control line, and fixed chemical injection valve.

It may be unnecessary to connect control line, it can be injected into production string directly through annulus of tubing and casing.Chemical medicament injection valve assembly includes chemical valve and fixed chemical injection joint, which is a wellbore equipment for controlling chemical medicament into tubing.
