In this paper, a new method called Integrated Evaluation Model is proposed, which uses sonic and other related well log data to evaluate pore pressure, that is, with giving consideration to the effect of clay content, porosity, vertical effective stress of shale sand formation on sonic velocity.
提出利用声波速度等测井资料检测地层孔隙压力的“综合解释方法” ,即同时考虑砂泥岩地层的泥质含量、孔隙度、垂直有效应力对声波速度的影响 ,先由相关测井资料求取泥质含量和孔隙度 ,再由声波速度计算垂直有效应力 ,最后通过有效应力计算地层孔隙压力。
3) sandstone formation
砂岩地层
1.
Acidizing is an effective method of rebuilding formation in sandstone formation, but it can also bring formation damage taken by forming oil-wetting formation, clay dispersing and flocculating, interfacial film and stringy milk.
砂岩地层酸化是改造地层的一种有效手段,但对砂岩地层酸化的同时,又可能形成油湿地层、粘土分散和絮结、界面薄膜和粘稠乳液对地层造成伤害。
2.
Tested samples were taken from different sandstone formations of Changqing, Erlian, Jilin Oilfield, Sichuan and Tarim Basin and Venezuela and hydraulic fracturing treatments would be performed in these formations.
采用长庆油田、二连油田、吉林油田和四川盆地、塔里木盆地以及委内瑞拉将要进行水力压裂施工的砂岩地层的岩样,用该方法测定最小主应力,将测定结果与长源距声波测井和微压裂测定结果对比,误差一般为2～3MPa,证实这是一种经济可靠的方法。

补充资料：泥岩
| 泥岩 mudstone 一种层理或页理不明显的粘土岩。矿物成分复杂，主要由粘土矿物（如水云母、高岭石、蒙脱石等）组成，其次为碎屑矿物（石英、长石、云母等）、后生矿物（如绿帘石、绿泥石等）以及铁锰质和有机质。质地松软，固结程度较页岩弱，重结晶不明显。常见类型有：①钙质泥岩。含适量碳酸钙，常见于大陆红色岩系和海洋、潟湖相的沉积岩层。②铁质泥岩。含较多的铁矿物，如赤铁矿、褐铁矿、针铁矿等，多见于红色岩层。③硅质泥岩。SiO2含量较高，不含或极少含铁质和碳酸盐质物，常与铁质岩、硅质岩、锰质岩相伴生。泥岩具吸水、粘结、耐火等性能，可用于制砖瓦、制陶等工业。
