摘要:
准噶尔盆地阜康凹陷东部斜坡区中侏罗统头屯河组是区域性重要的勘探目标层。依据研究区重点探井实测地层压力数据,分析异常高压在头屯河组中的纵向及平面分布,根据压力系数将研究区分为超强压区、超压过渡区—超压区和常压区。结合钻井、地震、测井以及薄片资料探讨了研究区异常高压的形成机理,认为沉积作用和构造作用是形成研究区异常高压的主要因素。区域性的异常高压是多个影响因素共同作用的结果,其中构造运动是研究区普遍存在异常高压的关键因素。
Abstract:
Toutunhe formation of the Middle Jurassic in slope area of eastern Fukang sag (Fudong slope area) in Junggar basin is a significant exploration target zone in this region. Based on the measured formation pressure data from key wells in this study area, this paper analyzed the vertical and horizontal distributions of abnormal high pressure in Toutunhe formation, presented three zones such as ultra?intense pressure zone, transition to overpressure zone and normal pressure zone in terms of the pressure coefficients, and discussed the formation mechanisms of these abnormal pressure zones by means of drilling, seismic, logging and thin?section data. The influencing factors for forming the abnormal pressure in this area are sedimentary facies and diagenesis as well as tectonic movement. The formation of the regional abnormal pressure is the result of multifactor combined actions, among which the tectonic movement is the key factor
