IMPROVEMENT OF TECHNOLOGY OF multistage hydraulic fracturing iN HORIZONTAL WELLS
Annotation. The paper describes the features of development of low-permeability heterogeneous reservoirs and technologies to increase oil recovery, used in the oil fields of Bashneft; the problem of improving the technology of multistage hydraulic fracturing in the Udmurt fields is solved. The following technologies are currently used at the fields of Bashneft: hydraulic fracturing (HF), sidetracking (ST), simultaneous-separate injection (SSI), physicochemical EOR methods. There are technologies of multistage hydraulic fracturing (MSHF), which have been and are being successfully applied at many Russian fields. The effect of MSHF is expressed in the increase of coverage factor and productivity of wells. An analysis of the prospects for the use of MSHF in various fields of Bashneft was carried out. The process of calculating development options was carried out using the Tempest More PC of the ROXAR company. The simulation resulted in a technological effect in the form of 70 thousand tons of additionally gained oil for 20 years per one well.
Keywords: oil fields, enhanced oil recovery methods, thermal, gas, chemical EOR methods, surfactants, polymer, alkaline flooding.
