Abstract
Today oil industry – one of the most developing and priority industries of Azerbaijan which plays a huge role in national economy. The need for this mineral constantly increases therefore for improvement of quality and decrease in cost of the product mining companies need to modernize constantly not only the oil-field equipment, but also to improve production processes. Now the increasing number of high-sulphurous and high-paraffinic oil fields is brought into development. As a result, the corrosion rate of the oil-field equipment increases, the output of wells decreases and expenses of mining companies in general raise.
Highlights
In recent years a considerable part of oil production is provided with inclusion in process of development of fields with heavy, high-viscosity crude oil
The kinematic viscosity of Muradkhanli and Sangacal crude oils was checked in the reduced ratio of SNPX-2005 additive
To measure influence of oil samples on dynamics of their viscosity, SNPX-2005 was added to Muradkhanli and Sangacal crude oils of 0.8 kg/t
Summary
In recent years a considerable part of oil production is provided with inclusion in process of development of fields with heavy, high-viscosity crude oil. Production and transportation of similar to crude oil are complicated because of high viscosity and temperature of hardening, abnormal rheological behavior. The feature of these rheological properties of crude oil is shown in inconstancy of their dynamic viscosity depending on tension of shift and speed of the movement of liquid. At transport high-paraffinic the intensive parafinization of pipelines, decrease in their capacity occurs crude oil that considerably complicates operation and leads to growth of labor and material inputs. High-paraffinic oil at low temperatures show sharply expressed non-Newtonian (viscoplastic, viscoelastic, thixotropic) properties without which it is impossible to organize rational operation of wells, collecting, preparation and transport of crude oil. Renewal of process of transfer demands sometimes creation of such starting pressure which in size considerably exceed operating pressures of pipelines, fittings and the equipment
