摘要： Hydraulic fracturing an individual reservoir fracturing layer of a subterranean formation to produce heterogeneous proppant placement is given in which pillars of proppant are placed such that the pillars do not extend the entire height of the fracture (for a vertical fracture) but are themselves interrupted by channels so that the channels between the pillars form pathways that lead to the wellbore. The method combines methods of introducing slugs of proppant-carrying and proppant-free fluids through multiple clusters of perforations within a single fracturing layer of rock, with methods of ensuring that the slugs exiting the individual clusters do not merge.

摘要： A method for producing minerals and, more specifically, for producing hydrocarbons, by hydraulic fracturing of the rock, can be used for the optimization of formation fracturing crack processing conditions. The method includes splitting a main stream of a propping agent suspension in a fluid at a mixer output into at least two flows having different volume delivery rates, and comingling the at least two flows before delivering to the hydraulic fracturing zone.

摘要： A method is given for creating a fracture, in a subterranean formation, that has a fluid flow barrier at the top, at the bottom, or at both the top and the bottom. The method is applied before or during a conventional hydraulic fracturing treatment and is used to limit undesired vertical growth of a fracture out of the productive zone. A lower-viscosity pad fluid is used to initiate the fracture; a higher-viscosity fluid containing barrier particles is then injected; a lower-viscosity particle-free fluid is then injected to promote settling (or rising) of the barrier particles and to finger through the slug of barrier particles and cut it into an upper and lower portion. If the barrier is to be at the bottom of the fracture, the barrier particles are denser than the fluids; if the barrier is to be at the top of the fracture, the barrier particles are less dense than the fluids. Optionally, between the barrier transport stage and the subsequent lower-viscosity stage, there may be a stage of a higher viscosity particle-free fluid that pushes the barrier particles farther into the fracture. To provide both upper and lower particles in one treatment, the pad stage may be of higher-viscosity, or the barrier particles may include particles less dense than, and more dense than, the fluid.
摘要翻译：给出了一种在地层中产生断裂的方法，该裂缝在顶部，底部或顶部和底部都具有流体阻流。该方法在常规水力压裂处理之前或期间应用，并且用于将不合要求的垂直生长限制在生产区域外。较低粘度的垫液被用于引发断裂; 然后注入含有阻挡粒子的较高粘度流体; 然后注入较低粘度的无颗粒流体以促进阻挡颗粒和手指通过阻挡颗粒的塞子的沉降（或上升）并将其切割成上部和下部。如果屏障位于裂缝的底部，则阻挡颗粒比液体更致密; 如果屏障位于裂缝的顶部，则阻挡颗粒比流体密度低。任选地，在阻挡输送阶段和随后的较低粘度阶段之间，可以存在将阻挡颗粒推入裂缝中的较高粘度的无颗粒流体的阶段。为了在一次处理中提供上部和下部颗粒，衬垫台可以具有更高的粘度，或者阻挡颗粒可以包括比流体密度小，密度更高的颗粒。
