Abstract: A method is described for making an opening (100) through a casing pipe (12) in a well (10) in which equipment is tipped to cut out the opening and cut out pieces from the pipe wall are captured, and also that a drill wedge is fitted in the pipe adjoining the opening to later conduct a drill string through the opening and drill a multilateral well in a formation. The method is characterised in that a module package with at least one cutting module (32) and a drill wedge module (38) suspended in a drill string (11) are lowered down into the well (10) and after the cutting, vibrations /strokes are generated to loosen the cut-out pipe parts that are caught by the module package, after which the drill wedge (38) is moved to a position adjoining the opening (100) and securely locked to the pipe (12) and the remaining module package with the cut-out pipe part is pulled up to the surface. Also described is a tool for making an opening (100) through a casing pipe (12) in a well (10) comprising equipment for cutting out the opening and capturing cut-out pieces from the pipe wall, and it is characterised by a module package of at least one cutting module (32) and a drill wedge module (38), and possibly a stroke/vibration module (34) and a retrieval module (36) for the capturing of loosened casing pipe pieces and the modules are mutually connected and suspended in a drill string (11). Also described is an application of the method and the modular tool.

Abstract: A method includes positioning at least one fluid nozzle disposed upon a distal end of a fluid conduit in a cased borehole penetrating a subterranean formation at a target zone of the subterranean formation. An abrasive laden fluid is then continuously pumped through the fluid conduit and through the at least one fluid nozzle at a pressure adequate to form at least one slot through the cased borehole. The abrasive fluid contains an aqueous medium, an abrasive, an optional acid, and a viscoelastic surfactant. While continuously pumping the abrasive fluid through the fluid conduit, the wellbore may be cleaned by returning debris and material generated in the operation to the surface with the fluid. In some instances, a portion of the forming a slot through the cased borehole is conducted simultaneous with the cleanout of the wellbore.

Abstract: Изобретение относится к нефтяной промышленности и может быть использовано для повышения нефтеотдачи посредством наиболее полной выработки пластов в осложненных горно-геологических условиях. Способ вторичного вскрытия продуктивных пластов геликоидной перфорацией, включает перфорацию, которую выполняют перемещая перфоратор вдоль оси скважины и одновременно вращают его вокруг собственной оси с образованием перфорационных каналов, причем скорости перемещения и вращения перфоратора выбирают исходя из условия, что полученная в результате перфорация представляет собой геликоиду с образованием полого пространства в обрабатываемом пласте, при этом в качестве перфоратора используют гидравлическую перфорационную насадку (гидравлический перфоратор), а шаг полученной геликоиды составляет 10 см., причем шаг геликоиды составляет 0,7 максимальной высоты щели. Перфорационные каналы объединяются друг с другом в пласте, благодаря малому шагу геликоиды и в заколонном пространстве образуется цилиндрическая горная выработка радиусом более 0,5 м. Площадь фильтрации жидкости из пласта в скважину в 5 раз выше, чем для открытого ствола скважины, что приводит к снижению скин-фактора до уровня гидравлического разрыва пласта без разрушения кровли или подошвы пласта или перемычек внутри пласта. Изобретение позволяет создать открытый забой скважины (полости) радиусом более 0,5 м, снизить фильтрационные сопротивления, снизить степень риска получения «стопа» при гидравлическом разрыве пласта и повысить эффективности фильтрации.

Abstract translation: 本发明涉及石油工业，可用于通过在困难地质条件下更完整的加工地层来改善石油采收率。 使用螺旋孔穿孔重新开采生产地层的方法涉及穿孔，其通过沿着钻孔的轴线移动穿孔器同时围绕其自身的轴线旋转而进行穿孔，从而形成穿孔通道; 穿孔机移动和旋转的速率在所产生的穿孔为螺旋形状的条件下选择，同时在待加工的地层中形成中空空间; 其中，穿孔器为液压穿孔附件（液压穿孔器）的形式，所产生的螺旋体的间距为10cm，螺旋形的间距包括间隙最大高度的0.7。 由于螺旋体的小间距，穿孔通道可以在地层内彼此联合，并且在柱周围的空间中形成半径大于0.5μm的圆柱形挖掘开口。 从地层到钻孔的液体过滤面积比开放井眼井中的5倍大，因此将皮肤因子降低到地层水力压裂的水平，而不会破坏地层的顶部或底部或障碍物 形成。 本发明允许产生半径超过0.5m的开放井面（空腔），以减少过滤阻力，从而降低地层水力压裂“停”的风险，并提高过滤效率。
