为开展潮间带石油勘探,查明黄河三角洲前缘及潮间带地貌特征和工程地质条件,山东海洋学院地质系与胜利油田钻采院协作,于1983年3月至9月,在小清河口至湾湾沟口之间长约150公里的黄河三角洲前缘及潮间带上,进行了典型地段地形坡度测量、地貌特征现场描述和拍照;采集了表层沉积土样75个,并做了粒度和矿物分析;在三条典型工程地质剖面上,用XV-100型地质钻机,钻孔7个,孔深均在3米左右,取原状土样24个,做了实验室土工试验、粘土矿物和微结构分析测定.同时,还开展了现场标准贯入试验、十字板剪切试验及外附力和内聚力现场试验等.提出了各土层粒度、外附力、内聚力、贯入击数、相对密度、十字板前切强度及容许承载力等参数指标的变化范围,并绘制了级配曲线图、沉积物应力强度图及强度包线.提交了“胜利油田沿岸潮间带地基地貌勘察报告”、“取样点与钻孔布置图”等成果.
In order to carry out the intertidal oil exploration and identify the topography and engineering geology of the front and intertidal zone of the Yellow River Delta, the geology department of Shandong Ocean University collaborated with the Drilling and Production Institute of Shengli Oilfield. From March to September 1983, On the front and intertidal zone of the Yellow River Delta, about 150 km long between Hekou and Wanwan Mizoguchi, terrain slope measurement and geomorphic characteristics were described and photographed. A total of 75 surface soil samples were collected and analyzed Particle size and mineral analysis; in three typical engineering geological sections, using the XV-100 geological drilling rig, drilling 7, the hole depth of about 3 meters, take the original soil samples 24, made laboratory tests, clay minerals And micro-structure analysis and determination.At the same time, also carried out on-site standard penetration test, cross-plate shear test and external force and cohesion field test, etc. The particle size, external force, cohesion, Relative density, cross-section shear strength and allowable bearing capacity and other parameters of the index range, and draw the gradation curve, sediment stress intensity maps and strength of the envelope. Submitted “Shengli Oilfield coastal tidal flat geomorphology survey report ”,“take Point and drilling layout ”and other achievements.
