川东北飞仙关组储层孔隙度计算方法探讨

川东北飞仙关组储层岩性、储集空间复杂,非均质性强,具有典型的缝洞性储层特征。常规测井响应受其影响较大,直接用三孔隙度测井曲线计算孔隙度难以满足要求。因此,本文结合川东北飞仙关组储层的具体地质特征,在详细讨论缝洞对三孔隙度曲线影响的基础上,提出了在用 Pe (U)法或三孔隙度曲线交会法准确识别岩性基础上建立计算模型求取孔隙度的思路。经实际资料验证,孔隙度计算精度有较大的提高。     

用多尺度形态学方法实现成像测井电导率图像的缝洞参数表征

裂缝和溶蚀孔洞为缝洞型储层提供了主要的储集空间和渗流通道,其分布的随机性和复杂性严重影响了对缝洞储层的定量评价。基于高覆盖率和高分辨率的电成像测井数据,采用多尺度数学形态学方法提取电导率图像中的缝洞孔隙度谱。选择不同尺度和形状的结构元素,构造不同种类的形态学滤波算子,实现井壁裂缝和溶蚀孔洞的电导率异常边缘检测。针对缝洞异常的边缘检测结果,用椭圆形函数拟合溶蚀孔洞,用多项式插值函数拟合裂缝边缘,继而提取缝洞参数并获得缝洞孔隙度谱。实验结果表明,用多尺度数学形态学方法对电导率图像的边缘检测有效地实现了缝洞的自动识别,验证了该方法计算缝洞孔隙度谱的准确性。

缝洞型储层缝宽动态变化及其对钻井液漏失的影响

以塔河油田12区为例,根据缝洞型碳酸盐岩储层的地质特征,建立考虑溶洞存在和漏失动态的有限元模型,研究裂缝的宽度变化规律及其对钻井液漏失的影响。结果表明:缝洞型储层裂缝宽度对井筒有效压力极为敏感,在几兆帕的正压差下,裂缝宽度增量便可达毫米级;钻井液漏失使得裂缝变宽,裂缝形态也相应地发生改变,增加了漏失控制难度;除了缝洞发育外,缝洞型储层的强应力敏感性也是井漏的重要原因之一;钻井中精细控制井筒压力,保持井筒压力微过平衡,并在钻进储层段前随钻加入毫米级高酸溶性暂堵堵漏材料,可以有效预防大部分漏失发生。

本期导读

本刊第一期是以突出报道“罗家寨”这一科技事件为主题目的,向读者展现了罗家寨构造的勘探、开发科学研究进展。而本期则着重于向读者展现我校的天然气开发与注气学术方向的研究现状。我校天然气开发与注气学术方向的科学研究团队,是“油气藏地质及开发工程”国家重点实验室的重要组成部分之一,为“中国加拿大天然气勘探开发技术培训中心”和中国石油集团公司“天然气成藏与开发”重点实验室提供重要学术与技术支持。本期刊登的专题报道《以天然气为特色,以提高油气采收率为目标,服务于石油天然气工业》,是由本刊编委会完成的。它以该团队的“学术思想、研究特色、主要研究方向。主要研究内容和成果”等几个侧面,向读者作了较详细的介绍。作为我国著名的气田、凝析气田开发专家,李士伦教授一直致力于复杂气田开发的新方法新技术研究,本期《提高凝析气藏采收率和气井产量新思路》是他学术思想新的结晶。如能对读者的学术研究或生产实践有所裨益,是我们的最大心愿。我国的天然气工业发展迅猛,西气东输工程不仅带动了全国各行各业的发展,也深刻地变革着广大人民对清洁能源的认识和利用。松辽盆地、莺歌海盆地等地区CO2的发现,使低渗透油田的注气开发有了资源保证。本期的特邀专栏重点探讨了气田开发与注气方面的理论与技术问题,对天然气工程及其相关领域的研究具有重要的指导意义。《基准面旋回层序与油层单元划分关系》由陈景山教授等人完成,论文所针对的是存在于“按基准面旋回层序界面的小层划分方案与传统的油气层四级划分方案”之间的矛盾问题,研究提出了不同级次湖泛面沉积的泥质盖层或隔、夹层为边界的,跨基准面旋回层序界面的砂体和油层四级划分方案。有一定的创新性,在实际应用中也具有可操作性。汤勇等作者撰写的《高温气藏近井带地层水蒸发和盐析研究》,建立了适于含极性物质水的烃类混合物气液液三相相平衡理论模型及地层水蒸发与近井带含水饱和度与地层水矿化度的函数关系,提出了高温高地层水矿化度、低含水饱和度的气藏,在降压开采过程中必须考虑“盐析”可能引起的地层伤害问题。《沁水盆地南部煤层气藏特征》由石书灿等人完成,提出了沁水盆地南部晚古生界煤层在经历了印支燕山两期煤化作用生成的煤层气,在喜马拉雅期遭受改造后的煤层气藏的特征及其成藏问题。作为我校石油工程领域的后起之秀,年轻的林元华教授为本期撰写了《计算膨胀管膨胀力的新方程》,所建立的膨胀管膨胀力理论模型,对钻井工程及其相关领域的实际问题具有可借鉴意义。李传亮教授在平常的交往中是一位保持低调和与人为善的人,但在学术与技术问题上则迥异。从质疑到追根溯源的探究精神,不仅在教学中使学生们受益匪浅,并且在其科研活动中屡获突破。《异常高压气藏开发上的错误认识》是他为本刊撰写的第二篇探讨与争鸣性论文,值得推荐。此外,本刊较大幅度地提高了论文的刊出量以回馈作者与读者对本刊的厚爱与关心。为作者服务是我们的力源,为读者服务是我们的宗旨,为社会的进步作出一份贡献是我们的最终目的。期待您的反响与支持。     

四川盆地纵向结构及原型盆地叠合特征

位于扬子克拉通西部的四川盆地在前震旦纪基底形成之后经历了多旋回构造演化,长期以来对其在不同地质历史时期的构造动力学性质、盆地类型存在争议;而理清不同时期盆地类型及其叠合特征对于上扬子克拉通盖层演化及油气勘探具有重要意义。作者利用穿过盆地的北西-南东向区域地震反射大剖面,结合钻井、野外地质、区域地质资料,对四川盆地的构造-沉积演化进行剖析,识别出5个区域不整合面,划分出5个盖层构造层,认为在纵向上形成了海相克拉通裂陷盆地(Z-S)、海相克拉通拗陷盆地(P_1l-T_2l)、海陆交互相断陷盆地(T_3x^1-T_3x^3)、陆相拗陷盆地(T_3x^4-J)、前陆盆地(K-Q)等原型盆地的有序叠合。
