Abstract

Ekspanderbare foringsavsnltt, som f.eks. forings- glideskjøter (55,57) eller ekspansjonsskjøter (200,202), er anordnet på motsatte sider av et frakturinltleringssted for å gl rom for forlngs- og formasjonsbevegelse under frakturerlng av en brønn. Frakturlnltlerlngsstedet kan være tilvelebragt ved å utforme åpninger (36) gjennom brønnf6rlngen (20) og så utforme vlfteformede slisser (34) i formasjonen omkring fSrlngen (20). Disse slissene (34) kan være utformet av en hydraulisk stråle som er rettet gjennom åpningen (36) og så dreid generelt om åpningens midtpunkt. Disse vifteformede slissene (34) omskrives av en vinkel om forlngens akse (38) som er betydelig større enn den vinkelen som omskriver selve åpningen (36), gjennom hvilken spalten (34) ble utformet. Disse teknikkene er spesielt anvendbare ved frakturerlng av horisontale brønner, men er også brukbare ved vertikale brønner.Expandable liner closures, such as liner sliding joints (55,57) or expansion joints (200,202) are arranged on opposite sides of a fracture insertion site to allow for extension and formation movement during fracturing of a well. The fracture injection site may be provided by forming openings (36) through the well casing (20) and then forming arcuate slots (34) in the formation around the casing (20). These slits (34) may be formed by a hydraulic jet which is directed through the opening (36) and then generally rotates about the center of the opening. These fan-shaped slits (34) are circumscribed by an angle about the axis (38) of the extension which is considerably larger than the angle defining the opening itself (36), through which the gap (34) was formed. These techniques are particularly useful in the fracturing of horizontal wells, but are also useful in vertical wells.
