Abstract

The invention discloses a system for testing a ground performance of a torsion impactor, comprising a testing joint, a rotating circulation joint, a supporting platform, a base, a gland, a plurality of sensors, a drill, a liquid storage tank, a gate, a circulation pump, a data collector, and a monitor. The system can test the parameters such as pressure drop, amplitude, frequency, acceleration andvibration impact force under a working condition of the torsion impactor, determines the influence caused by the parameters such as the drilling fluid flow, drilling fluid density, drilling fluid viscosity and drill quality on the torsional impactor, provides an efficient and fast method for the ground testing of the torsion impactor, and provides theoretical basis and guidance for tool optimization and factory testing.

Description

technical field [0001] The invention relates to the field of oil and gas drilling, in particular to a ground performance testing system for a torsion impactor. Background technique [0002] With the deepening of the development of oil fields in the east of my country, the development of the west of China has been continuously intensified, and the proportion of exploration and development of deep wells and ultra-deep wells has also been increasing. However, with the increase of well depth, the hardness and plasticity of deep formations increase sharply, which in turn leads to the deterioration of rock drillability, and the sharp decrease of mechanical penetration rate, thereby greatly reducing drilling efficiency. A large number of research data show that the stick-slip vibration at the drill bit is the main cause of low drilling efficiency. [0003] In order to solve the problems of severe stick-slip vibration and low ROP of drill bits in deep hard-plastic formations, speed...
