Carboniferous–Permian marine transgressions in the Jiyang Depression

International Journal of Mining Science and Technology 2014年第1期24卷 87-92页

作者： zhang Kuihua Chen Shiyue zhang guanlong Department of Earth Resource and Information China University of Petroleum Qingdao Western New Prospect Research Center Shengli Oilfield

In recent years, great attention has been paid to oil and gas exploration in the Carboniferous-Permian strata of the Bohaiwan basin, especially the Carboniferous-Permian marine transgression, using data from drilling, outcrops and carbonate acid-insoluble residue experiments together with the tectonic evo- lutionary history of the peripheral orogenic zones of the North China plate and the Tan-Lu fault zones. The .＇;tudy concludes that marine transgressions took place on six occasions during Carboniferous-Perm- ian time in the Jiyang Depression. The marine transgressions were concentrated in the Late Carbonifer- ous： two marine transgressions occurred in the early Late Carboniferous, and the scale of the first was smaller and the time was shorter than those of the second. The other four marine transgressions hap- pened in the late Late Carboniferous, the first and the fourth of which were larger in scale and longer in time than the second and the third. The seawater came from the Jiaobei area, the eastward part of the Qinling-Dabie residual sea basin, and invaded progressively as a planar flow from south to north and from east to west. These findings have great significance for thorough analysis of the sedimentary characteristics and evolution of the Carboniferous-Permian strata in the livang Denression.

The rigid-plastic analysis of mental forming simulation is formulated as a discrete nonlinear mathematical programming problem with equality and inequality constraints by means of the finite element technique. An iteration algorithm is used to solve this formulation, which distinguishes the integration points of the rigid zones and the plastic zones and solves a series of the quadratic programming to overcome the difficulties caused by the nonsmoothness and the nonlinearity of the objective function. This method has been used to carry out the rigid-plastic FEM analysis. An example is given to demonstrate the effectiveness of this method.

Geochemical characteristics of Carboniferous volcanic rocks from the Wulungu-Luliang area, Junggar basin: constraints on magma source and tectonic setting

引用

Chinese Journal Of Geochemistry 2015年第4期34卷 515-524页

作者： Wei Liu Kuihua zhang guanlong zhang Peiming Zhou Qizhi Wang School of Resources and Geosciences China University of Mining and Technology The West Research Center Company of Sinopec Shengli Oilfield

The Carboniferous volcanic rocks in the Wulungu-Luliang area are mainly andesites of medium- to high-K calc-alkalic series. Volcanic rock samples have relatively high alkali(Na2O + K2 O = 4.7 % to 6.8 %) and low Ti O2contents(0.7 % to 0.9 %), relatively high Mg O(2.5 % to 3.4 %) and Mg#(49.9 % to 67.1 %), high rare earth element(REE) contents, and relatively high K2 O contents(1.7 % to 3.1 %). Chondrite-normalized REE patterns show light REE enrichment((La/Yb)N= 4.15 to 5.19)with weak Eu anomalies(d Eu = 0.75 to 0.92). These samples are enriched in large-ion lithophile elements but relatively depleted in high field strength elements. The trace elements and REE patterns are similar to those of Setouchi and central Ryukyu high-Mg andesites, indicating a highMg andesite source. Relatively high Y contents(16.7 to24.4 ppm), and relatively low Sr/Y ratios(17.2 to 38.8) and Ti O2contents(0.7 % to 0.9 %) exclude the possibility of slab melting. Low Sr/Nd(16.6 to 42.8), Ba/Th(66.4 to266.8), and U/Th(0.2 to 0.3) indicate that the influence of slab-derived fluids is low. The ratios of Ce/Th(4.9–7.3), Ce/Pb(1.8–4.2), Ba/Rb(7.99–22.03), Ba/Th(66.4–266.8), and La/Sm(3.6–4.3) are similar to ratios found in subducting sediment melts. Relatively high ratios of K/Nb(1357–3258),Th/La(0.28–0.42), Zr/Nb(8.8–27.1), and especially Th/Nb(0.48–1.25) suggest that the magma was assimilated and contaminated by upper continental crust. These characteristics, along with the ratios of La/Yb, Sc/Ni, Th/Yb, Ta/Yb,Ce/P2O5, and Zr/Ti O2, demonstrate that the earlier Carboniferous volcanic rocks in the Wulungu-Luliang area were generated in a continental island-arc setting.

通过对济阳坳陷二叠系砂岩储集层岩石的压汞实验分析,结合薄片分析与扫描电镜观察,利用能反映储集层孔隙结构特征及渗流性能的参数,分析该区二叠系储集层岩石的储集特征。结果表明,该区二叠系碎屑岩储集层以成分成熟度和结构成熟度均较高的中粗粒及含砾中粗粒石英砂岩为主,属于典型的低孔低渗—特低孔特低渗型储集层;主要储集空间为次生孔隙和裂缝,具有孔喉半径小、分选性和连通性较差、渗流能力较差的孔喉特征;最大孔喉半径是决定其渗流能力的主要因素,反映了次生孔隙的发育对其储集性能的重要性。研究结果还表明,控制该区二叠系碎屑岩储集层发育的主要地质因素是沉积主水道(高能河道或分流河道)的分布型式、酸性水介质溶蚀相的发育程度及构造条件。

准噶尔盆地下二叠统风城组为一套重要的烃源岩,对该时期沉积环境的认识存在海相与湖泊相的争议。根据研究区及邻区露头、地震、钻测井及岩心等资料,明确了准噶尔盆地南缘博格达山的形成时期与盆内地质结构,恢复了盆地早二叠世构造-沉积格局,并分析了风城组的石油地质特征。研究结果表明:石炭纪末期,东博格达山与伊林黑比尔根山东缘分隔了准噶尔盆地与吐哈盆地,准噶尔盆地由残留海闭塞形成了海迹湖。风城组沉积时期,盆地北部石西凹陷与石钱滩凹陷主要发育冲积扇;西北缘、中央坳陷与博格达地区为海迹湖沉积环境,继承了海洋的咸水环境与生物;受盆内凸起与水下低隆的控制,准噶尔盆地形成4个沉积中心,半深湖-深湖亚相在咸水环境下发育较好的烃源岩。准噶尔盆地腹部各凹陷与博格达山周缘下二叠统广泛分布,深埋藏条件下可能蕴含极其丰富的天然气资源,为下一步有利的勘探方向。

乌伦古拗陷是否发育石炭系烃源岩以及烃源岩发育层位一直存在争议。在乌伦古拗陷伦6井北发现了石炭系姜巴斯套组烃源岩露头,证实了乌伦古拗陷确实发育石炭系烃源岩。该剖面烃源岩以泥岩、粉砂质泥岩为主,为一套滨浅海相沉积。烃源岩潜力分析结果表明,该套烃源岩有机质丰度高,ITOC平均为1.23%;有机质类型好,以II1型为主,利于生油;烃源岩处于高成熟演化阶段。同时,烃源岩的饱和烃、芳烃特征反映该烃源岩形成于还原的微咸水环境,说明该区滨浅海相的沉积环境有利于烃源岩的发育,能够形成规模的源岩层,具备良好的勘探前景。
