【摘要】：研究井区葡萄花油层作为松辽盆地中央坳陷区主要的开发层系之一,2011年提交石油控制储量四千多万吨,具有良好勘探开发前景。然而,由于储层特性认识困难、测井解释精度不高等种种因素,导致油气勘探开发进展不明朗。论文首先运用薄片、X衍射及压汞等资料研究葡萄花油层的储层岩石学特征、储层孔隙特征等,然后有效地利用岩心资料和测井等资料,以地球物理测井理论及方法为基础,重点对测井解释方面研究,在建立储层参数模型与油层有效厚度标准解释处理井前,先对深侧向电阻率和声波时差资料进行了标准化,再得到有效厚度分布图。最后根据测井解释结果结合沉积、构造等因素,提出可部署加密井或扩边井的有利区和射孔、压裂及试油建议井。研究的结果表明:以3700系列的测井值为准校正量,深侧向电阻率无需进行趋势面法处理,声波时差校正值分布在-25~25μs/m间;得出划分油层有效厚度标准满足岩性在泥质粉砂岩以上,含油性在油斑级别以上,孔隙度大于等于10%,渗透率大于等于0.1×10-3μm2,含水饱和度小于等于61%,声波时差大于等于253μs/m,电阻率大于等于6Ω·m时,解释层段可能含油。针对断层附近及砂岩边界的剩余油,在主力砂组姚一段Ⅱ砂组预测了两类有利区还提出了让+1-1等9口井射孔方案。
[Abstract]:As one of the main development strata in the central depression of Songliao Basin, the Putaohua reservoir in the research well area was submitted to the petroleum control reserves of more than 40 million tons in 2011, which has a good prospect of exploration and development. However, because of the difficulty of understanding reservoir characteristics and the low precision of logging interpretation, the progress of oil and gas exploration and development is not clear. In this paper, the petrological characteristics and pore characteristics of the reservoir are studied by means of thin slice X diffraction and mercury injection data, and then the core data and logging data are used effectively, based on the geophysical logging theory and method. Before establishing the reservoir parameter model and the reservoir effective thickness standard interpretation processing well, the deep lateral resistivity and acoustic time difference data are standardized first, and then the effective thickness distribution map is obtained. Finally, according to the result of log interpretation combined with sedimentation, structure and other factors, the favorable areas and perforation, fracturing and oil test suggestion wells for deployable infill wells or extended edge wells are put forward. The results show that with the logging value of 3700 series, the depth lateral resistivity does not need to be processed by trend surface method, and the correction value of acoustic moveout is between -25 渭 s / m and 25 渭 s / m. It is concluded that the effective thickness standard for the division of reservoir meets the lithology above the argillaceous siltstone. If the oil content is above oil spot level, porosity is greater than 10, permeability is greater than 0.1 脳 10 ~ (-3) 渭 m ~ (2), water saturation is less than or equal to 61 ~ (-1), sonic moveout is greater than or equal to 253 渭 s / m, resistivity is greater than or equal to 6 惟 m, the interpretation layer may contain oil. In view of the remaining oil near the fault and the sandstone boundary, two favorable areas are predicted in the second member of the main sand group, Yao first member, and the perforation scheme for 9 wells of 1-1 class is put forward.
