Abstract

Изобретение относится к геофизическим исследованиям нефтегазовых скважин и может быть использовано для определения параметров гидроразрыва пласта (далее в описании ГРП), в частности для определения геометрических характеристик трещин ГРП (азимут, длина, средняя ширина раскрытия, высота (интервал раскрытия)). Техническим результатом изобретения является возможность определения с высокой точностью большего количества геометрических параметров трещины, а именно азимута, длины, средней ширины раскрытия, высоты (интервала раскрытия) непосредственно в процессе ГРП. Технический результат достигается тем, что в способе определения параметров трещины гидроразрыва пласта в скважине, включающем измерение распределенных температуры и давления в скважине и вычисление по ним геометрических параметров трещины, дополнительно производят измерение механических деформаций обсадной колонны скважины, при этом измерение параметров механических деформаций производят с помощью тензодатчиков, размещенных на наружной поверхности обсадной колонны скважины в заданном порядке в пределах интервала перфорации. Благодаря проводимому в реальном времени мониторингу распределенных физических параметров скважины заявляемый способ позволяет определять азимут, длину, ширину раскрытия трещины, высоту (интервал раскрытия) трещины при выполнении гидродинамического воздействия на проницаемый коллектор, что, в совокупности с геомеханической моделью развития трещины, позволяет оптимальным образом уточнять режимы закачки с целью достижения целевых параметров трещины ГРП.The invention relates to geophysical studies of oil and gas wells and can be used to determine the parameters of hydraulic fracturing (hereinafter in the description of hydraulic fracturing), in particular to determine the geometric characteristics of hydraulic fractures (azimuth, length, average opening width, height (opening interval)). The technical result of the invention is the ability to determine with high accuracy a larger number of fracture geometrical parameters, namely azimuth, length, average opening width, height (opening interval) directly in the process of hydraulic fracturing. The technical result is achieved by the fact that in the method for determining the parameters of a fracture in a well, including measuring distributed temperatures and pressures in the well and calculating the geometrical parameters of the fracture, the mechanical deformations of the well casing are also measured, strain gauges placed on the outer surface of the casing of the well in a given order within the perforation interval. Due to the monitoring in real time of the distributed physical parameters of the well, the inventive method allows determining the azimuth, length, width of the crack opening, height (opening interval) of the crack when performing hydrodynamic effects on the permeable reservoir, which, together with the geomechanical model of fracture development, allows to specify the optimal way injection modes to achieve target fracture parameters.
