Abstract:
A re-fracturing method using a perforating gun system in a multistring wellbore casing with an inner well casing installed in an outer well casing. The charges in the perforating system includes include a case, a liner positioned within the case, and an explosive filled within the liner. The liner shaped with a subtended angle about an apex of the liner such that a jet formed with the explosive creates an entrance hole in the inner well casing and the outer well casing; the liner having an exterior surface, the exterior surface substantially conical proximate the apex; the subtended angle of the liner ranges from 100° to 120°. The method includes covering the existing openings with the inner casing, perforating with the perforating system and creating constant diameter entrance holes in the outer casing and fracturing through the inner casing and outer casing.

Abstract:
Изобретение относится к горному делу и может быть применено для дилатансионного торпедирования скважины. Способ включает размещение в скважине в границах продуктивного пласта торпеды, содержащей рассредоточенный заряд взрывчатого вещества, состоящий из п точечных зарядов (n≥2), массу которых определяют из анализа диаграммы объемного деформирования породы продуктивного пласта при условии достижения максимального радиуса зоны дилатансионного разуплотнения. Затем их взрывают с заданным временем задержки, определяемым из условия совпадения фаз сжатия во взрывных волнах от соседних зарядов. При взрывании образуются взрывные газы. Торпеда содержит, по меньшей мере, один невзрывной газовыделяющий элемент, образующий при взрывании точечных зарядов дополнительный объем газов, суммирующийся с объемом взрывных газов, полученным от взрывания точечных зарядов взрывчатого вещества, и обеспечивающий увеличение радиуса зоны дилатансионного разуплотнения. При этом согласно изобретению, для получения необходимого дебита скважины в расчетном интервале значений коэффициента прироста дебита скважины (1,5-15), рассчитывают длину взрывной волны и массу невзрывного газовыделяющего элемента по предложенным заявителем формулам. Изобретение обеспечивает прогнозируемый прирост дебита скважины.
Abstract:
The present disclosure envisages a shock/blast wave assisted fracking method which includes explosive heating of a fracking fluid. The method includes heating the brine solution using either an electrical heater or laser beams or microwave generators. Brine solution is filled up in a chamber comprising a plurality of pilot cracks. The brine fluid can be heated using a plurality of electrical coils or a laser beam generator or a microwave generator. The boiling of the brine solution results in formation of high pressure steam, which is subsequently directed through a plurality of valves, towards the cracks inside the oil well. The rapid flow/release of the steam through the valves results in creation of shock waves/blast waves. The shock waves are exerted upon the existing cracks thereby inducing crack propagation.
