摘要/Abstract

摘要： 以鄂尔多斯盆地陕北地区延长组致密砂岩储层为研究对象，在岩石学、孔隙结构、储层物性特征研究的基础上，开展储层敏感性流动实验，以此评价该地区致密储层的敏感性及敏感机制。研究结果表明：陕北地区延长组致密砂岩储层敏感性主要表现为中等偏强速敏、中等偏弱水敏、无酸敏到弱酸敏、弱碱敏、强压敏；临界流速、临界矿化度、临界pH值3个特征临界值分别为1.0 mL/min、8 500 mg/L、8.5。敏感程度主要受矿物成分和孔隙结构的影响。研究区储层速敏的形成源于其孔隙填隙物——高岭石的存在；绿／蒙混层及伊/蒙混层矿物是引起水敏及盐敏的主要因素；铁白云石及含铁绿泥石等酸敏矿物的存在使部分岩样显弱酸敏；极其复杂的孔喉结构、极易受压变形的片状喉道以及岩样中云母、黏土等塑性矿物导致储层具强压敏性。

Abstract: Taking the tight sandstone reservoir of the Yanchang Formation in the northern Shaanxi as an example, and based on the reservoir characteristics about lithology, pore texture and physical properties, the core flow tests on reservoir sensitivities were conducted. Based on the results, the tight sandstone reservoir of the Yanchang Formation showed medium to strong velocity sensitivity, medium to weak water sensitivity, nil to weak acid sensitivity, weak alkali sensitivity,and strong pressure sensitivity. The results also gave three critical values:the critical velocity of 1.0 mL/min, the critical salinity of 8 500 mg/L, and critical pH of 8.5. Sensitivity is mainly affected by mineral composition and pore structure. The velocity sensitivity is the result of kaolinite in pores; chlorite/montmorillonite interstratified mineral and illite/montmorillonite interstratified mineral are the main factor causing water sensitivity and salt sensitivity; ankerite and iron-containing chlorite make part of the samples weakly acid sensitive; extremely complicated pore structure, easily compressed flake throat and plastic minerals in samples, such as mica and clay are the main controlling factors on the reservoir pressure sensitivity. The results provides theoretical basis for the subsequent development in the studied area.
