致密油储层自然条件下很难产出油气,需要进行大规模的压裂改造才能见到效果,支撑剂的选择直接影响压裂裂缝导流能力的大小,因此本章将分析支撑剂嵌入对裂缝导流能力的影响,主要采用实际地层岩板,使用仪器模拟地层条件,对不同铺砂浓度、闭合压力下支撑剂的嵌入进行研究,共计11种方案,总结支撑剂嵌入的影响因素及规律,为致密油气藏得压裂设计提供科学依据。
In tight oil reservoirs, it is very difficult to produce oil and gas under natural conditions and large-scale fracturing reformation is needed to see the effect. The choice of proppant has a direct impact on the flow conductivity of fracturing fractures. Therefore, The influence of flow capacity on the formation of proppant is studied by using actual strata and using instruments to simulate the formation conditions. The embedment of proppant under different sand concentrations and closing pressures is studied. A total of 11 schemes are summarized, and the influencing factors and regularities of proppant embedding are summarized Tight oil and gas reservoirs have been fractured to provide a scientific basis for the design.
