Rock torsional impact generation test device

Abstract

The invention relates to a rock torsional impact generation testing device. The device comprises a multifunctional testing machine faucet center pipe; the top of a center pipe connector is in threadedconnection with the multifunctional testing machine faucet center pipe; the upper end of the center pipe connector is sleeved with a via hole type electric brush slip ring; the lower end of the center pipe connector is connected with an upper connector; the other end of the upper connector is in threaded connection with a lower connector; the lower connector is connected with an electric cylinderbase into a whole through a connecting piece sleeving the periphery of the lower connector; and the connecting piece is connected with the lower connector through double keys to realize impact torqueload transmission; a bearing plate is fixedly connected to the center line of the electric cylinder base; electric cylinders symmetrically mounted on the electric cylinder base on two sides of the bearing plate; and impact heads of the electric cylinders impact the bearing plate; and the via hole type electric brush slip ring and the electric cylinders are connected to transmit power electricityand control signals. The device is reasonable and compact in structure, can well simulate the working characteristics and parameter changes of a downhole torsional impact tool, and meets the requirements of a petroleum drilling downhole torsional impact tool simulation test.

Description

technical field [0001] The invention belongs to the field of oil drilling and production industry, and in particular relates to a rock torsional impact generation test device in an oil drilling and production downhole tool test system. [0002] technical background [0003] With the rapid consumption of conventional oil and gas resources, the exploration and development of deep and ultra-deep oil and gas fields have become more difficult and costly. In order to meet the increasing demand for oil and gas energy year by year, major oil fields have developed new downhole tools to increase the production and efficiency of oil and gas field exploitation. There are many types of downhole tools for oil and gas, and the market volume is huge, but they all work in the downhole of several thousand meters, and they are in the harsh working environment of high temperature and high pressure for a long time. If a fault occurs during the work, it cannot be repaired in the well, and it is di...

Problems solved by technology

There are many types of downhole tools for oil and gas, and the market volume is huge, but they all work in the downhole of several kilometers, and they are in the harsh working environment of high temperature and high pressure for a long time. If a fault occurs during the work, it cannot be repaired in the well, and it is difficult to judge, analyze and determine. The cause of the failure can only be repaired from a few thousand meters well, which wastes time, costs and reduces production efficiency, which virtually increases the development cost of oil and gas fields
