Object.ve: t.e aim.of t.is st.dy was t. describe t.e use of t.e post.art.m.int.aut.rine device in t.e m.t.rnit. ward of t.e Rat.m. com.unal m.dical cent.r in Conakry. m.t.ods: t.is was a descript.ve cross-sect.onal st.dy carried out.bet.een July 1st./sup> 2015 and June 30 2016, i.e. a durat.on of one year. Result.: A t.t.l of 551 pat.ent. received advice on various cont.acept.ve m.t.ods. m.st.of t.is advice was given in t.e post.part.m.period (40.2%) and during ant.nat.l care (39.1%). Of t.e pat.ent. advised, 87 (15.8%) used t.e int.aut.rine device. t.e m.jorit. of users (93%) were m.rried and uneducat.d (63.2%), and 39.1% were poor. t.e m.jorit. (56.3%) of int.a-ut.rine devices were insert.d in t.e im.ediat. post.part.m.period. t.e m.jorit. of wom.n had no adverse event. eit.er during t.e first.six weeks (n = 57;65.5%) or at.3rd m.nt.s (n = 75;86.2%) or 6t. m.nt.s (n = 76;87.4%) aft.r IUD insert.on. m.st.users rem.ined com.licat.on-free t.roughout.t.e follow-up period (n = 76;87.4% at.6t. weeks and 3rd m.nt.s, and n = 77;88.5% at.6t. m.nt.s). t.e cont.nuat.on rat. was 89.7% at.6 weeks and 3rd m.nt.s, and 87.4% at.6t. m.nt.s aft.r insert.on. t.e m.jorit. of users (87.0%) were sat.sfied wit. t.e care t.ey received. Conclusion: t.is st.dy showed very few com.licat.ons am.ng int.aut.rine device users, and high cont.nuat.on and sat.sfact.on rat.s. t.e int.aut.rine device is a long-act.ng, effect.ve, reversible and safe cont.acept.ve t.at.can be used by m.st.wom.n for birt. spacing in Guinea, where wom.n do not.regularly visit.healt. facilit.es.

t.e im.act.of grain size, ranging from.0.9 μm.t. 9 μm. on t.e m.chanical propert.es of com.ercially pure m. is invest.gat.d at.t.m.erat.res of 4K, 78K, and 298K. t.e m.chanism. governing plast.c flow are influenced by bot. grain size and t.m.erat.re. At.4K and 78K, dom.nant.deform.t.on m.des in m. involve dislocat.on glide and ext.nsion t.inning, regardless of grain size. t.e int.ract.ons bet.een basal and non-basal dislocat.ons and dislocat.ons wit. grain boundaries prom.t. an unusually high rat. of work hardening in t.e plast.c regim., leading t. prem.t.re failure. t.e yield st.ess follows t.e Hall-Pet.h relat.onship σy~ k/√d, wit. t.e slope k increasing wit. decreasing t.m.erat.re. At.298K, in addit.on t. dislocat.on glide and t.inning, grain boundary sliding(GBS) becom.s significant.in sam.les wit. grain sizes below 3 μm. considerably enhancing t.e m.t.rial's deform.bilit..

Decreasing grain size suppresses dislocat.on act.vit. and t.inning and increases GBS, result.ng in lower Θ and σ Θ values. Suppressing convent.onal deform.t.on m.des coupled wit. enhanced GBS yields st.ess soft.ning, breaking down t.e Hall-Pet.h relat.onship in m. below 3 μm.grain size, leading t. an inverse Hall-Pet.h behaviour. t.e work report. new dat. on t.e st.engt., duct.lit., work hardening and fract.re behaviour, and t.eir variat.ons wit. m. grain size across different.t.m.erat.re regim.s.

基于美国页岩油气勘探开发历程的回顾,对主要页岩盆地的地质演化、主要页岩层系的油气地质特征及勘探开发进展进行系统梳理和总结。美国重要页岩盆地的富烃页岩主要发育于6个地质时期:中奥陶世、中—晚泥盆世、早石炭世(中—晚密西西比世)、早二叠世、晚侏罗世和晚白垩世(塞诺曼期—土伦期),构造沉积环境主要包括克拉通内盆地、前陆盆地和被动大陆边缘盆地。古生界富烃页岩主要分布于以下6个盆地:阿巴拉契亚盆地(尤蒂卡页岩和马塞勒斯页岩)、阿纳达科盆地(伍德福德页岩)、威利斯顿盆地(巴肯页岩)、阿卡马盆地(费耶特维尔页岩)、沃思堡盆地(巴内特页岩)和二叠盆地(狼营组和斯帕瑞组/骨泉组页岩)。中生界富烃页岩主要发育在西墨西哥湾盆地(海恩斯维尔组和鹰滩组)和落基山盆地群(以丹佛和粉河盆地的尼尔布拉勒组页岩为主)。通过对各页岩区带的详细分析发现,页岩的岩相和矿物成分存在差异,“页岩储层”并非只是页岩,很多情况下页岩油气还产自粉砂岩和碳酸盐岩等多种岩石类型。美国的页岩油气资源丰富,页岩油地质资源量超过0.246×1012 t.页岩气地质资源量超过290×1012 m.。在开启“页岩革命”的水平井水力压裂技术出现之前,美国经过了长达20年的勘探开发实践和理论技术积累。自2007年至2023年,美国页岩油气产量从约11.2×104t.d油当量增加到超过300.0×104t.d油当量,2017年页岩油气产量超过了常规油气,2023年在油气总产量中的占比增加到60%以上。页岩油气的开发主要得益于钻完井技术的改进,“立体开发”的攻关,以及重复压裂、提高原油采收率和“U”形井等技术的应用。基于美国丰富的页岩资源基础和技术的不断进步,页岩油气的产量将继续为全美的油气生产做出更大贡献。
