| 摘 要： | 地层孔隙压力是钻井工程设计、施工的重要参数,获取准确合理的地层孔隙压力剖面是钻井工程井身结构设计优化和钻井液密度窗口确定的重要参考依据。川东北YB地区油气资源丰富,纵向沉积巨厚海、陆两相沉积体,发育多套含气层系,勘探开发潜力巨大,但是该区地质条件复杂,纵向地层孔隙压力剖面预测困难,严重影响了该区钻井工程设计优化及安全高效钻井。利用测井资料,运用伊顿法地层孔隙压力预测理论,分段建立陆相地层正常压实趋势线及海相地层等压趋势线,开展纵向海陆两相地层孔隙压力剖面综合预测研究,经实钻资料验证,预测结果与实钻符合率较高,能有效指导现场钻井施工。

| Abstract: | Formation pore pressure is an important parameter for drilling engineering design and construction. An accurate and reasonable pore-pressure profile can be a major reference for optimizing casing programme design and determining mud weight window. YB area in northeastern Sichuan Basin is abundant in oil and gas resources, in which longitudinally deposits marine and continental facies sedimentary bodies with huge thickness. And several gas-bearing beds develop. Therefore, the area has a great potential for e... |
