Abstract

The invention relates to a multifunctional test and experiment platform for a desk research of jet drilling. The multifunctional test and experiment platform for the desk research of the jet drillingcomprises a power module, an experimental condition control module, a test and detection module, a fluid circulation module, and a drilling assembly. The power module comprises a micro-drilling experiment device and a mud pump; the experimental condition control module comprises a center control unit and a confining pressure control unit; the test and detection module comprises a sensing detectionunit, a data acquisition unit, a data processing unit, and a display storage unit; and the fluid circulation module comprises a water faucet, a water tank, a sedimentation and a filtration ditch, a sewage pump, and a simulation wellbore with an opened upper end and a sealed and transparent lower end. According to the multifunctional test and experiment platform for the desk research of the jet drilling, a practical jet drilling process can be simulated in a laboratory, and necessary conditions can be created for carrying out the laboratory experiment of the jet drilling; and automatic controlcan be achieved in an experiment process, the non-visual jet drilling process in the underground can be visualized, and a semi-empirical research is transferred into a scientific and quantified research.

Description

Technical field

[0001] The invention relates to the technical field of jet drilling, in particular to a multifunctional test and experiment platform used for indoor research of jet drilling. Background technique

[0002] Jet drilling (Jet Drilling) is a kind of hydraulic action that uses pressure drilling fluid to generate high-speed jets when flowing through nozzles embedded in jet drill bits to assist the drill bit to break rocks and clean bottom hole cuttings, which can effectively increase the mechanical drilling speed. Drilling method. In the process of jet drilling, under the condition of the bottom of the well using the jet bit, the drilling fluid is ejected from the nozzle at high speed to form a jet, which is submerged by the drilling fluid in the wellbore, and its movement and development are restricted by the bottom and wall of the well. Belongs to submerged non-free jet.

[0003] The high-pressure jet formed in the process of jet drilling can well clean the bottom hol...
