无因次裂缝导流能力是油井增产作业中一个主要的设计参数 ,它是裂缝传输流体至井眼的裂缝传导能力与地层输送流体至裂缝的传导能力的比较。它在压裂设计上的应用追溯到 5 0年代水力压裂技术的最早时期。尽管在数值模拟方面有所进展 ,但也许因为在目前这样一种重要理论中它的相对简单性 ,因此连续使用 4 0年之后它仍是一个主要的设计参数。然而 ,作为任意设计参数 ,它的值与测定中使用的数据一样有价值。近年来文献中的测试报道和 70年代初期其他研究表明 ,多数工程师使用的裂缝导流能力的数据源对裂缝的有效渗透率估计过高 ,竟高出一个数量级。这一结果导致当今的水力压裂增产处理在生产能力方面受到限制 ,并且与油藏的潜在供油能力不相匹配。因此 ,了解该试验参数 ,使当今的工程师们可以测出输入数据 ,以便更精确地计算出无因次裂缝导流能力值 ,从而提高油井产能 Non-dimensional fissure Diversion capability is a major design parameter in well stimulation operations. It is a comparison of the fracture conductivity of fractured fluids to the wellbore and the ability of the fluid in the formation to transport fluids to the fracture. Its application in fracturing design dates back to the earliest stages of hydraulic fracturing in the 1950s. Although there has been some progress in numerical simulations, it may still be a major design parameter after 40 years of continuous use, perhaps because of its relative simplicity in the present important theory. However, as an arbitrary design parameter, its value is as valuable as the data used in the assay. Recent reports in the literature and other studies in the early 1970s show that the data source for the fracture conductivity used by most engineers estimates the effective permeability of the fracture excessively an order of magnitude higher. This result has resulted in today’s hydraulic fracturing stimulation being limited in terms of production capacity and incompatible with the potential supply of oil reservoir. Knowing the test parameters, therefore, enables engineers today to measure input data to more accurately calculate dimensionless flow conductivity values ​​and thereby increase well productivity
