渤海湾盆地锦州南油田太古界变质岩潜山储层裂缝三维地质建模
|
摘要
针对渤海湾盆地锦州南油田太古界变质岩潜山裂缝型油气藏的储层裂缝发育状况、分布规律的复杂性和多级性,以及较难开发的实际问题,为进一步研究古潜山岩性分布特征、储集空间分类及裂缝发育状况,综合运用岩心、录井、测井和地震等多学科资料,进行单井常规测井和成像资料的对比标定,对古潜山岩性进行识别,并根据储层成像测井响应特征,将储层自上而下分为残积带、风化壳、缝洞裂缝带、内幕斜交高角度裂缝带和致密结晶带,重点对储层裂缝发育区和裂缝发育方向进行描述和预测;进而建立了锦州南油田太古界变质岩潜山储层裂缝三维地质模型,落实了研究区储层裂缝发育状况及分布规律,提出高效合理的开发方案。实钻开发井表明,建立的潜山裂缝地质模型较好地预测了储层裂缝发育的有利部位。
Aiming at the fracture development condition, the distribution rule's complexity and multistage, as well as more difficult development problems of Jinzhounan Neo-Archean metamorphic buried hill fracture reservoir in the Bohai bay, and taking Frac-Man, RMS as platforms, this paper utilize integrated data, such as seismic, core, testing and logging and other information, as well as the buried hill lithological recognition and the fracture controlling factor analysis, the multi-disciplinary geological study is carried out, and then the three-dimensional geological model of the Neo-Archean metamorphic buried hill reservoir is established. Subsequently, the growth condition and the distribution rule of fracture reservoir in the research area are studied, and the highly effective development plan is proposed as well. The actual field drilling and well data show that the geological model of buried hill fracture reservoir predicts a favorable position for the development.
