The use of a liquid destructor with flow into the stream during the injection of the fracturing mixture

Abstract

For most modern development systems, hydraulic fracturing is the main method of intensification and maintenance of hydrocarbon production. Hydraulic fracturing is achieved with the volume of communicating voids between the granules of fractional proppant. The volume of voids should be maximized, which is achieved by selecting the optimal proppant fraction composition, and in addition, hydraulic fracturing fluid, the choice of which is based on a number of competing factors: high viscosity, which provides the necessary hydraulic width created at the buffer stage of the crack, as well as prediction of subsidence proppant in the fracture and subsequent premature stop of the injection, which creates additional costs. One of the new solutions, which will increase the efficiency and expand potential objects for hydraulic fracturing, is the use of a liquid destructor with a flow into the stream during the injection of the fracturing mixture.

Proposals for the adjustment of design solutions in the formation of a strategy for the effective operation of oil wells

“…To evaluate the effectiveness of infill drilling using tight wells, it is necessary to consider the above-mentioned geological and technological risks [9][10][11].…”

Features of bottomhole zone treatment and formation stimulation by large volumes of hydrochloric solutions

“…The main reasons for this difference in the nature of the impact on the formation are higher specific volume and acid consumption during treatment. Thus, large-volume selective acidizing with an increase in the specific volume of acid of more than 5 m3 per meter with a simultaneous increase in the acid flow rate of more than 5 m3/hour per meter of treated thickness at an injection pressure below the hydraulic fracture pressure increases the likelihood of inclusion of previously dead sections of the formation and additional oil reserves [9][10][11][12][13][14]. Most large-volume selective acidizing with increased acid composition flow rate are characterized by an increase in formation pressure while increasing or maintaining the productivity ratio.…”
