Abstract


The paper presents the results of laboratory tests of a drill pipe centralizer-turbulator developed at the Department of Oil and Gas Well Drilling of the Almetyevsk State Technological University. Laboratory tests were conducted on a laboratory stand for simulating inclined-horizontal drilling (INGD) for four values of fluid flow rate: 0,001 m3/s; 0,003 m3/s; 0,005 m3/s; 0,007 m3/s. During laboratory tests of a prototype of a drill pipe centralizer-turbulator, the following dependencies were determined: frequency and amplitude of turbulent flow on fluid flow rate. It was found that the peak amplitude of the turbulent flow at a flow rate of 0,003 m3/s without the experimental sample of the centralizer is equal to 0,0001 mm/s, with the experimental sample it is equal to 0,001 mm/s, which indicates the operability of the experimental sample of the centralizer capable of creating a turbulent flow of liquid, which can reduce the possibility of sludge settling in inclined and horizontal sections of the well.

Key words:
