Description
Существующие способы гидроразрыва не позвол ют получать н пласте вертикальные трещины.Existing fracturing methods do not allow vertical fractures to be produced on the formation.
Предлагаемый способ не имеет этого недостатка, так как в скважину спускают обсадную колонну с ослабленными участками в виде продольнььх пазов или сверлений, разрущаемых при нагнетании жидкосги гидроразрыва. Способ заключаетс в том, что перед спуском эксплуатационной колонны в скважину, в теле колонны, с наружной ее стороны, в местах, расположенных против продуктивного пласта, создают участки , ослабленные вдоль оси колонны- Ослабление участков обеспечиваетс наличием пазов со сверлени ми на концах или сверлений.The proposed method does not have this drawback, since a casing with weakened sections is lowered into the well in the form of longitudinal grooves or bores destroyed during the injection of hydraulic fracturing fluid. The method consists in that, before lowering the production string into the well, in the body of the string, from the outer side, in places located opposite the reservoir, create areas weakened along the axis of the string. .
После спуска в скважину обсадной колонны и ее цементажа производ т гидроразрыв. При нагнетании жидкости гидроразрыва ослабленные места колонны деформируютс , а так как прочно сцепленный с колонкой цемент вл етс хрупким и не способен к большим деформаци м , как сталь, то в нем, до разрыва колонны по ослабленному месту, образуетс вертикальна трещина. После разрыва колонны жидкосгь гидроразрыва входит в трещину, расшир ет ее и вызывает образование вертикальной трещины в пласте.After the casing and its cementing are lowered into the well, hydraulic fracturing is performed. When the fracturing fluid is injected, the weakened areas of the column are deformed, and since the cement strongly adhered to the column is brittle and is not capable of large deformations, like steel, a vertical crack forms in it until the column breaks along the weakened area. After the fracturing of the column, the fracturing fluid enters the fracture, expands it and causes the formation of a vertical fracture in the formation.
Предметизобретени .The subject invention.
Способ гидроразрыва пласта, отличающийс тем, что, с целью образовани трещины в продуктивном пласте, в скважину опускают колонну с ослабленными участками в виде продольных пазов или сверлений , разрушаемых при нагнетании жидкости гидроразрыва.A method of hydraulic fracturing, characterized in that, in order to form a fracture in a producing formation, a column is inserted into the well with weakened sections in the form of longitudinal grooves or holes that are destroyed when a fracturing fluid is injected.
