Problems solved by technology

During the drilling process, problems such as large frictional resistance and underpinning pressure are also likely to cause downhole failures such as differential pressure sticking, especially when sliding drilling, it is impossible to apply real and effective WOB to the drill bit, which reduces the drilling efficiency and prolongs the drilling time. cycle

Abstract

The invention discloses an experiment rack, an experiment system and a test method used for testing a drilling tool. The experiment rack comprises a tool clamping mechanism and multiple support columns (20). The tool clamping mechanism includes clamping arms (16) corresponding to the support columns (20) one by one. One end of each support arm (16) is connected with a corresponding support column(20), and the other end of each clamping arm (16) is capable of clamping and fixing a to-be-tested drilling tool (8). The clamping arms (16) are capable of rotating by taking the central lines of thesupport columns (20) as axes and are telescopic. According to the invention, working performance of the to-be-tested drilling tool (8) can be compositely evaluated, and the optimal working state and the working parameters of the tool are obtained; support is provided for selection of drilling tools in all kinds of types and sizes in a working place; probability of occurrence of underground accidents is reduced; and objectives of optimization of working characteristics of tools and reducing of expenditure and cost are achieved.

Description

technical field [0001] The invention relates to the field of oil drilling experiment equipment, in particular to an experiment rack for testing drilling tools, an experiment system for testing drilling tools, and a method for testing the vibration and shock characteristics of hydraulic pulse jets. Background technique [0002] With the depletion of shallow oil and gas resources, oil and gas drilling has shifted to deep wells, ultra-deep wells, high-pressure oil and gas wells, marine deepwater drilling and other fields, and the number of extended-reach wells and long horizontal wells is also increasing. Drilling projects have to face more and more complex situations, drilling deeper and deeper, poor formation drillability, high requirements for high temperature resistance of drilling tools, difficulty in pressurizing drill bits, complex geological conditions, etc., especially in deep formations. The low drilling speed severely restricts the drilling speed of deep wells and di...
