摘要： Methods including the pumping of fracturing fluid carrying proppant. Simultaneously particulate is pumped made of substance that under subterranean temperature releases hydrochloric or etching acid precursor, wherein the said acid precursor reacts with the formation water and produces acid. The methods stimulate the inflow of formation fluid towards the well due to cleaning of the surface of hydrofracture and due to growth of its area.

摘要： This invention relates to the oil and gas industry, in particular, to methods affecting the formation productivity at the oil and gas production stage.A method for fracture propping in a subsurface layer, which ensures a reliable protection of wells from the proppant carryover from the fracture, has been proposed. According to the proposed method, a fracturing fluid is mixed with a propping agent and particulate binding material wherein the particles have an average length-to-width ratio of less than or equal to about 10; thereafter, a formation fracturing process is implemented. Then, the particulate binding material hardens and forms a homogenous firm mass with the propping agent, which impedes the closing of the fracture and precludes proppant carryover from the fracture. Or, a fracturing fluid composition obtained by mixing a propping agent with a binding compound in the form of a powder whose size varies from about 1 to about 500 μm. A gravel-packed filter is then constructed; the said filter is based on the application of the working fluid comprising a propping filler and particulate binder with a length-to-width ratio of less than or equal to 10, or comprising a propping filler and a binding compound in the form of a powder with a size varying from about 1 to about 500 micrometers.
摘要翻译： 本发明涉及油气工业，特别涉及影响油气生产阶段的地层生产力的方法。 已经提出了一种在地下层中的断裂支撑的方法，其确保了井与支撑物从裂缝中的携带的可靠保护。 根据所提出的方法，将压裂液与支撑剂和颗粒结合材料混合，其中颗粒的平均长宽比小于或等于约10; 此后，实施地层压裂处理。 然后，颗粒结合材料与支撑剂硬化并形成均匀的固体物质，这妨碍了断裂的闭合，并排除了支撑剂从裂缝中的残留。 或者，通过将支撑剂与尺寸为约1至约500μm的粉末形式的结合化合物混合而获得的压裂液组合物。 然后构建砾石充填过滤器; 所述过滤器基于工作流体的应用，该工作流体包括长度与宽度比小于或等于10的支撑填料和颗粒粘合剂，或包含粉末形式的支撑填料和结合化合物 其尺寸从约1至约500微米变化。
