Annotation:
The development of highly productive fields in the Russian Federation is characterized by oil production decrease, progressing water cut increase as well as by low-permeable areas of a heterogeneous reservoir, classified as hard-to-recover reserves [1]. The development of residual oil reserves concentrated in such conditions using traditional methods is characterized by low efficiency and is forwarded by a further increase of unrecoverable oil reserves share. By now, a significant number of technologies for oil displacement intensification have been developed [2]. One of the universal means of increasing wells productivity and the sweep factor and converting low-productivity deposits into profitable ones is hydraulic fracturing of a formation (HF) [2]. The article considers a technique to increase drainage capacity, reservoir coverage by intensification of production and oil reserves recovery in complicated geological-technological conditions, for example, in a thin-layered heterogeneous medium by increasing the accuracy of localization of main hydraulic fracturing cracks in the formation. The proposed method is based on preliminary selective pilot gas-hydraulic fracturing in the bedding plane of rocks of a thin-layered heterogeneous formation before the main hydraulic fracturing.
