14. HMSP advantages Absence of impact action.
Bigger square of opening per 1 m. of perforation (200 – 560 cm2).
Independent roller location.
The mill’s outlet from the perforator up to 80 mm.
The length of fissure is increased while column opening due to application of mill composite materials.

Opening of a number of steel marks of production columns.
The possibility of opening at different drive fluids.
The technology does not allow the possibility of the formed fissures pinch and cutting disks’ hooking in the fissures.
Direction of the resulted fissures with milling of 120О increases the possibility of overlapping with the direction of formation stress.
Application of pumping units type CA– 320 or their analogs.

*скважина № 305 до проведения ГМЩП на объекте Бб эксплуатировалась на объекте Т-Фм, и технологическую эффективность корректно рассматривать как входные параметры
*Before HMSP well № 305 at Bb site was operated at site T-Fm and technological efficiency is right to consider as inlet parameters
Results:
Primary average incremental oil rate– 5.9 t/day, current– 4.8 t/day
In wells №№ 174, 182_2 and 302 productivity ration increased at the average for 3 times.
Technological efficiency of HMSP exceeds the results of other methods application at formations of Bb fileds of “LUKOIL” OJSC

20. Conclusions:
The advantage of multifunctional hydro-mechanical slotting perforation (HMSP) is absence of fugacity, what allows not to break the Cement Sheath Integrity behind the column.
Opening area under HMSP in interval of 5 m. exceeds opening area under cumulative perforation 20 – 50 times, depending on thickness of the mill and type of HMSP.
HMSP application in arrangement with packer allows to reduce a lot the time of workover crew, regarding to other types of perforation, thus speeding up the bringing in a well.
HMSP application with phasing of 120О contributes to more efficient WT performance, as the direction of the fissures resulted after HMSP increases the possibility of overlapping with the direction of formation “stress”.
Performance of multifunctional HMSP after squeeze jobs, VIR allows to decrease production watering and reduce the possibility of wellbore leakage. 20
