Abstract

The invention discloses an automatic system for drilling fluid water analysis and detection. The automatic system comprises an inner cup taking component, an inner cup recycling component and a filtrate detection component. The inner cup taking component comprises a forward placing station, a cup taking mechanism, a clamping device, a conveying mechanism used for moving the clamping device, a grouting device located on the conveying path of the conveying mechanism and a pressurizing plug located on the conveying path of the conveying mechanism. The inner cup recycling component comprises an inner cup clamp used for receiving an inner cup from the clamping device, a first rotating mechanism, a second rotating mechanism and a lifting component; and the filtrate detection component comprisesa filter cup, and a liquid receiving cup, a liquid taking cup, an injection pump and a position changing mechanism which are sequentially connected with the filter cup. The problems that in the priorart, drilling fluid filtration loss detection is low in automation degree and consumes manpower, and only one type of ions can be titrated at a time are solved, and the purposes of improving the automation degree of the inner cup taking and recycling process and rapidly conducting titration detection on different ions are achieved.

Description

technical field [0001] The invention relates to the field of drilling fluid measurement, in particular to an automatic system for drilling fluid water analysis and detection. Background technique [0002] The drilling fluid (mud) is affected by the pressure difference in the well, and part of the water seeps into the formation. This phenomenon is called the water loss performance or fluid loss characteristic of the drilling fluid. The water loss (filter loss) of the drilling fluid has a very important impact on the stability of the drilling fluid system, and is an important parameter for maintaining the stability of the wellbore wall. Therefore, at the drilling site, the drilling fluid engineer or drilling engineer will frequently check the It is measured. The measurement methods in the prior art are all measured by API water loss meter or high temperature and high pressure water loss meter. The process includes: turning the instrument upside down and opening the cover, pou...
