有效的一体化模拟裂缝性致密油储层压裂生产过程是评价压裂设计的关键之一。为此，基于嵌入式网格的基质裂缝全域空间流固耦合数值模拟方法，进一步考虑天然裂缝影响下裂缝动态扩展、低速非线性渗流、基质与裂缝应力敏感，实现了裂缝性致密油储层压裂生产一体化多机理模拟。进而分析了天然裂缝、非线性渗流对裂缝扩展及生产动态的一体化影响规律。研究结果表明：模型可以在生产过程中任意时刻模拟压裂，为重复压裂、加密井的设计分析提供了有效工具。当基质岩石的抗拉强度由10.2 m.a降到2.3 m.a时，破碎带逐渐增大，滤失作用增加，导致主裂缝长度降低8%-9%，但可以增加累产油量17.5%至61.1%，影响作用显著且主要影响早期的日产油量。与启动压力梯度模型相比，低速非线性渗流可以更好地预测致密油生产动态。该方法为裂缝性致密油储层压裂生产一体化的动态预测、规律分析、工艺优化提供了高效工具。

Ho.m.um.o.ide Film.as a Saturable Abso.ber fo. 2μm.Q-Switched Fiber Laser

Chinese Physics Letters 2017年第5期34卷 48-51页

作者： m.F.A.Rahm.n m.F.m.Rusdi m.Q.Lo.m.n m.B.H.m.hyuddin A.A.Latiff A.H.A.Ro.o. K.Dim.ati S.W.Harun Departm.nt o.

Electrical Engineering University Teknologi Mara Shah Alam 40450 Malaysia

This wo.k repo.ts o. the use o. the ho.m.um.o.ide （Ho.o.） po.ym.r film.as a saturable abso.ber （SA） fo. generating stable Q-switching pulses o.erating in a 2μm.regio. in a thulium.do.ed fiber laser cavity. The SA is prepared by diluting a co.0}ercial Ho.o. po.der and then m.xing it with po.yvinyI alco.o. （PVA） so.utio. to.fo.m.a Ho.o.-PVA film. A tiny part o. the film.abo.t 1m.×1 m. in size is sandwiched between two.fiber ferrules with the help o. index m.tching gel. When inco.po.ated in a laser cavity driven by a 1552-nm.pum., stable Q-switching pulses are o.served at 1955nm.within the pum. po.er range o. 363 491 ro.. As the pm.p po.er increases within this range, the repetitio. rate rises fro.0}26 kHz to.39 kHz, as the pulse width dro.s fro.0}4.22μs to.2.57μs. The laser o.erates with a signal-to.no.se ratio.o. 47dB, and the m.xim.m.o.tput po.er and the pulse energy o.tained are 2.67m. and 69ng, respectively. o.r results successfully dem.nstrate that the Ho.o. film.can be used as a passive SA to.generate a 2μm.pulse laser.
