    • 摘要: Nile Delta which covers approximately 60,000 square kilometers represents the most important gas province in Egypt whereas its fields provide two-thirds of the gas production in Egypt. The Nile Delta province begins to display its hydrocarbon potentiality in the early 1960s. Nidoco field is located in the shallow water offshore Nile delta. Abu Madi formation (Messinian age) is the most important formation through all the section where it represents the main gas producing reservoirs in the Field. The production of the field is coming from two sand reservoir levels;Abu Madi level 2&3 which are characterized by fluvial-deltaic sandstones. The purpose of this paper is to perceive the Messinian gas bearing reservoirs and channelized sand distribution inside Abu Madi formation using seismic attributes and amplitude versus offset (AVO) technique. The results indicated that the seismic attributes and AVO aided to give a complete picture about the Messinian reservoirs distribution and characterization in the field. Also the results show that there are still promising locations of prospective Abu Madi Level 2&3 which are proposed to be drilled in the field.

    • 摘要: 研究区位于珠江口盆地恩平凹陷北部隆起带,近几年在中浅层相继获得多个商业性油田发现,特点是目的层砂体厚度普遍小于15 m,主力油层通常具有“亮点”振幅异常和第三类AVO特征。老地震资料低频成分缺乏,分辨率不足,并且AVO特征与钻井吻合度低,难以满足中浅层小断层精细解释、以及储层和流体研究的需求,针对如上问题,开展了以鬼波压制为核心的宽频地震处理。与老资料相比,本次宽频处理数据分辨率和信噪比显著提高,小断层得到了很好的刻画,深层和基底成像信噪比进一步提升,井震标定效果、井旁道AVO特征与钻井的吻合度更好。基于宽频处理成果和老成果分别提取主力层的振幅属性和吸收衰减属性,对比表明,宽频处理成果预测的储层展布和含油气特征更合理,进一步证实了以鬼波压制为核心的宽频地震处理技术在储层和流体研究方面的可靠性和优越性。

    • 摘要: 孔洞型碳酸盐岩含油气性较好,是一种重要的储油载体,但目前碳酸盐岩孔洞内的流体性质没有得到充分研究。为降低碳酸盐岩孔洞型油气藏的开发风险,提高采油效率,对孔洞内的流体进行识别十分必要。通过数值模拟的方式对填充流体时碳酸盐岩孔洞的波场进行了正演模拟:首先,设计了具有不同横向尺度的孔洞模型,研究了利用AVO(振幅随偏移距的变化)技术进行流体识别时地下地质体的横向尺度问题,为进一步研究流体的性质作了较好的铺垫;然后,设计了填充不同纵横波速度比(v_(P)/v_(S))的流体的孔洞模型,研究了含不同v_(P)/v_(S)流体时的孔洞AVO响应特征,得到了相关的AVO响应曲线;最后,设计了含不同泊松比流体的孔洞模型,研究了含不同泊松比流体孔洞的AVO响应特征。研究结果表明,AVO现象具有横向尺度限制,即当孔洞的横向尺度在400m(5倍波长)~600m(7.5倍波长)之间时,振幅随入射角的增大而呈现出较明显的增大,而当横向尺度增加到1000m(12.5倍波长)时,振幅随入射角的变化趋势保持不变;当围岩介质的性质保持不变,而孔洞所含流体的泊松比减小时,AVO曲线的截距绝对值明显增大,而斜率无明显变化;AVO响应曲线的截距信息比斜率信息更有参考价值;针对不同的地质情况应该提取不同的地震属性,或者提取几种属性进行交会分析,才能更好地识别流体。该研究成果对孔洞内流体的识别具有一定的指导意义。

    • 摘要: Mediterranean Sea considered as a main hydrocarbon province in Egypt as a huge reservoirs have been discovered till now. Port Fouad marine is a gas and condensate field located in Eastern Mediterranean Sea about 30 KM off Egyptian coast, in a water depth of about 30 m. The Concession is operated by PETROBEL on behalf of Petrosaid (Port Said Petroleum Company). The field was put on production on April 1996, from the Miocene turbidities sands of Wakar Formation plus Pilocene Kafr EL Sheikh Formation. Darfeel field is located within Port Fouad Concession, seven wells have been drilled till now and producing from Pliocene section (Kafr El Sheikh Formation). Pliocene is the main reservoir in Darfeel field which characterized by turbidities sand stone. The aim of this work is to identify the distribution of turbidities sand and characterize sand reservoirs using AVO (amplitude verses offset) and seismic attributes techniques. The workflow is starting from conventional seismic interpretation, maps (time, depth, and amplitude), depositional environments, and finally structure setting. In addition to use some of unconventional seismic interpretation such as seismic attributes. AVO analysis and attributes had been applied in a temp of differentiate between gas sand reservoirs and non-gas reservoirs. The final result aid to identify the reservoir distribution and characterization of sand reservoirs through the field. So, the use of different seismic techniques is powerful techniques in identifying reservoir distribution.

    • 摘要: 地球物理反演的本质是利用物性和弹性参数揭示地下介质的属性和含油气特征。拉梅参数是储层预测和流体识别中最常用的弹性参数。根据纵、横波速度与拉梅参数的关系,基于Zoeppritz方程提出了一种新的以剪切模量、密度相对变化率为参量的反射系数方程,结合稀疏性原则和核模约束提高反演的横向连续性,添加先验信息约束,实现从叠前地震数据中直接提取剪切模量和密度信息,从而减少间接计算带来的累积误差,该反演方法比常规三参数反演具有更高的稳定性。建立4类AVO模型,分别利用该方法、Aki-Richards方程与Gray近似方程进行正演模拟、误差分析和条件数分析,结果表明了该方法的反演结果与原始数据吻合得更好且稳定性更高。基于最小二乘法对一维层状模型反演证明,该方法能更准确地反演μ、ρ,在井数据充裕的情况下,能够较准确获取拉梅常数λ。将该方法用于实际叠前地震数据反演,井位处的反演结果与测井曲线基本一致,能够准确识别岩性,为后续分析提供准确的弹性参数。

    • 摘要: 吉尔嘎朗图凹陷白垩系的赛汉塔拉组煤层为含气量较低的低煤阶褐煤,寻找含气量相对高的"甜点区"是该地区优化钻井部署所面临的难点.针对该区沉积环境复杂、煤层厚度横向变化大等特点,动态正演模拟分析了煤层的含气性、厚度以及顶板岩性对煤层AVO的影响,总结AVO的响应特征和AVO属性的变化规律,判定AVO烃类检测的可行性和适用条件.结果表明,P+G属性烃类检测效果与实际钻井含气量和累计产气量的吻合率达到75%以上,利用该属性并结合区域地质认识,指出了有利的勘探方向.

    • 摘要: 针对SRME和Radon变换压制自由表面多次波的近道多次波残留和伤害有效波等问题,主要采用基于AVO属性分析的多次波剔除法对近道多次波进行压制,该方法在迭代更新过程中,受近道多次波影响容易出现更新误差,同时迭代更新降低计算效率.本文对基于AVO属性分析的多次波剔除法进行改进,利用中远道地震数据进行约束,通过AVO正演模拟构建有效波的AVO属性抛物线,进而对近道多次波进行压制.该方法在构建有效波AVO属性抛物线过程中,无需迭代更新,提高了计算效率.同时该方法在多次波压制过程中不受多次波的影响.由模型测试及实际地震资料应用效果证明,本文方法能够较好的压制自由表面多次波,该方法为油气田进一步精细勘探开发提供可靠保障.

    • 摘要: With the development of exploration of oil and gas resources,the requirements for seismic inversion results are getting more accurate.In particular,it is hoped that the distribution patterns of oil and gas reservoirs can be finely characterized,and the seismic inversion results can clearly characterize the location of stratigraphic boundaries and meet the needs of accurate geological description.Specifically,for pre-stack AVO inversion,it is required to be able to distinguish smaller geological targets in the depth or time domain,and clearly depict the vertical boundaries of the geological objects.In response to the above requirements,we introduce the preprocessing regularization of the adaptive edge-preserving smooth filter into the pre-stack AVO elastic parameter inversion to clearly invert the position of layer boundary and improve the accuracy of the inversion results.

    • 摘要: The hydrocarbon detection method based on pre-stack gather data has higher accuracy and reliability than those methods based on post-stack data.This kind of method requires that pre-stack gather data have high SNR(Signal Noise Ratio)and obvious AVO(amplitude variation with offset)characteristics.Therefore,it is important to optimize the pre-stack gathers and enhance their AVO(Amplitude variation with offset)effect.This abstract proposes a gather optimization and AVO feature enhanced method for hydrocarbon detection.The gather optimization method based on the improved BEMD(bidimensional empirical mode decomposition).It starts from the original signal directly,and can be optimized as pre-stack gather steadily and quickly.Then,the characters of CTKEO(Corss Teager-Kaiser energy)algorithm which is strong sensitivity to interaction of two signals is fully utilized to enhance AVO features.The method proposed in this abstract provides a good data base for pre-stack inversion from gather optimization to AVO feature enhancement.
