Sequence sedimentary evolution and reservoir distribution in the third and fourth members of Sinian Dengying Formation,Gaomo area,Sichuan Basin,SW China

Based on comprehensive analysis of cores,thin sections,logging and seismic data,the sequence stratigraphy and sedimentary evolution of the third and fourth members of Sinian Dengying Formation(Deng 3 and Deng 4 members for short)in the Gaomo area of Sichuan Basin were investigated,and the favorable zones for reservoir development in the Deng 3 Member and Deng 4 Member were predicted.(1)Two Type I and one Type II sequence boundaries are identified in the Deng 3 and Deng 4 members.Based on the identified sequence boundaries,the Deng 3 and Deng 4 members can be divided into two third order sequences SQ3 and SQ4,which are well-developed,isochronal and traceable in this area;the SQ3 thins from west to the east,and the SQ4 thins from northwest to southeast.(2)The sedimentary environment from the depositional period of SQ3 to SQ4 has experienced the evolution from mixed platform to rimmed platform,and the platform rimmed system on the west side is characterized by the development of platform margin microbial mound and grain shoal assemblages.The intraplatform area is a restricted platform facies composed of a variety of dolomites,and there are local micro-geomorphic highlands of different scales and scattered intraplatform mounds and shoals.(3)The Deng 4 Member reservoirs,with obvious facies-controlled characteristic,are mainly distributed in the upper part of high-frequency upward shallow cycle and the high-stand systems tract of the third-order sequence vertically,and are more developed in the platform margin belt than in the intraplatform belt,and more developed in the Gaoshiti platform margin belt than in the west Suining platform margin belt on the plane.(4)Three types of favorable reservoir zones of Deng 4 Member have been finely delineated with 3D seismic data;among them,the mound and shoal facies zones developed in the ancient highlands of the intraplatform are the first choice for the next exploration and development of the Deng 4 Member.

膏摩法对衰老模型鼠外周血淋巴细胞DNA损伤程度影响的实验研究

探讨膏摩"足三里"延缓衰老的机理。方法:对臭氧衰老模型小鼠"足三里"穴实施膏摩法治疗后,用彗星实验(Comet Assay)检测小鼠外周血淋巴细胞DNA的损伤程度。结果:膏摩小鼠外周血淋巴细胞DNA的拖尾率显著下降(P<0.05),尾长显著减短(P<0.05),差异有统计学意义。结论:膏摩法能够通过提高机体自身抗自由基氧化损伤的能力,减轻淋巴细胞DNA的损伤程度,从而达到延缓衰老的目的。

川中高磨地区震旦系灯影组三、四段层序沉积与储集层分布

基于岩心、薄片、测录井及地震资料的综合分析,对四川盆地高磨地区震旦系灯影组三段+四段层序地层及沉积演化开展研究,并对其有利储集层发育区进行预测。研究表明:①灯影组三段+四段可识别出两个Ⅰ型和一个Ⅱ型层序界面,据此划分为SQ3和SQ4两个三级层序,这两个层序在区内发育完整,具有良好的等时性和可追踪对比性,SQ3西厚东薄,SQ4北西厚南东薄。②SQ3至SQ4经历了由混积台地到镶边台地的演变,西侧的台地镶边体系以发育台缘微生物丘和颗粒滩组合为特征,台内为多种白云岩组成的局限台地相,且存在规模不一的局部微地貌高地,发育星罗棋布的台内丘滩体。③灯四段储集层表现出明显的相控性,纵向上主要分布于高频层序向上变浅旋回上部和三级层序高位域;平面上,台缘储集层较台内发育,高石梯台缘储集层较遂宁以西台缘发育。④通过三维地震精细刻画出灯四段3类有利储集层发育区,指出台内古地貌高地丘滩相区是下一步灯四段勘探开发的首选区带。

高磨地区非均质储层转向酸导流能力研究

针对四川盆地高磨地区碳酸盐岩储层非均质性强、渗透率差异大的特点,分别从酸液含量、储层温度、注酸排量、酸液用量等方面开展了不同类型转向酸导流能力研究。实验结果表明:在相同条件下的高酸含量黏弹性转向酸体系刻蚀岩板形成的酸蚀裂缝导流能力高于低酸含量黏弹性转向酸体系的导流能力;随着酸液含量、储层温度、注酸排量及酸液用量的增加,酸蚀裂缝导流能力增大,但当酸的体积分数大于20%以后,转向酸酸蚀裂缝导流能力增加有限。研究的转向酸导流能力成果在高磨地区开展了现场应用,实现了气井的高导流能力,测试产气量达80.01×10^(4)m^(3)/d。

膏摩疗法对举重运动员腰肌疲劳的疗效研究

目的研究膏摩方配合推拿治疗举重运动员腰肌疲劳的效果。方法选取40名女子举重运动员,随机分为对照组和膏摩治疗组,周期为12周。研究前、研究后即刻、研究后5 min记录体表温度及VAS疼痛程度,并于训练后即刻和12 h检测血清睾酮(T)、皮质醇(C)、肌酸激酶(CK)和血尿素(BUN)。结果从体表温度变化情况可以看出,不管是治疗前与治疗后还是治疗前与治疗后5分钟推拿治疗和膏摩配合推拿治疗比较均有极显著性差异(P<0.001);VAS标尺测定法显示推拿治疗和膏摩配合推拿治疗比较都有极显著性差异(P<0.001);血清T和C水平在第6周和第12周相比于对照组有显著差异(P<0.05),而CK和BUN对结果意义不大(P>0.05)。结论膏摩疗法治疗腰肌疲劳效果显著,是比较安全且有效的治疗方法,值得临床推广。
