Способ выбора объектов в пробуренных скважинах для проведения гидроразрыва пласта на месторождении с применением системы поддержки пластового давления - ППД, включающий исследование бурящихся скважин наклонометром, выделение с его помощью природных субвертикальных и вертикальных трещин на указанных участках, в том числе не пересекающих ствол скважины, построение на основе статистической обработки показаний наклонометра полярной диаграммы - «розы» распределения азимутальных направлений вертикальных и субвертикальных природных трещин в продуктивном пласте, отличающийся тем, что производят совмещение полярной диаграммы - «розы» распределения азимутальных направлений природных вертикальных и субвертикальных трещин в продуктивном пласте с координатами их вертикальной и субвертикальной пространственной ориентации в околоскважинном пространстве в диапазоне 60-90°, зарегистрированных для каждого продуктивного объекта в конкретном стволе скважины, с положением этой скважины на карте месторождения с показанным расположением на ней остаточного невыработанного целика нефти и положением контура вытеснения нефти водой через нагнетательные скважины, и выбирают для ГРП ту скважину, в раствор «розы» азимутальных направлений природных трещин с угловой характеристикой в пределах 15-20° которой попадает менее 20% величины поперечного контура площади заводнения с применением системы ППД.The method of selecting objects in drilled wells for hydraulic fracturing in a field using a reservoir pressure support system - pressure maintenance method, including the study of drilled wells with a tiltmeter, the identification of natural subvertical and vertical fractures in these areas, including those that do not intersect the wellbore, the basis of the statistical processing of the readings of the tiltmeter of the polar diagram - “roses” of the distribution of azimuthal directions of vertical and subvertical natural wells in the reservoir, characterized in that they combine the polar diagram - “roses” of the distribution of azimuthal directions of natural vertical and subvertical cracks in the reservoir with the coordinates of their vertical and subvertical spatial orientation in the near-wellbore space in the range of 60-90 °, recorded for each production object in a particular wellbore, with the position of this well on the field map with the location on it of the remaining untreated target for oil and the position of the oil-water displacement circuit through the injection wells, and choose the well for hydraulic fracturing, into the “rose” solution of the azimuthal directions of natural cracks with an angular characteristic of 15-20 ° which contains less than 20% of the cross-sectional area of the waterflood using the system PPD.
