【摘要】：徐家围子断陷营城组中基性火山岩分布广,普遍含气,资源潜力巨大,但埋深大,储层物性差,需通过老井中侧钻水平井或打新水平井获得较好的产能。另外,松辽盆地北部深层目前已经探明的2000亿方探明储量中,有较大比例的储量区需要采用水平井技术进行开发。该论文是针对火山岩地层的各向异性、非均质性强等因素的影响由于水平井测井响应与直井存在较大差异,针对垂直井火山岩评价技术不能完全适用于水平井资料评价,使测井解释符合率低、储层参数计算精度差等问题,针对古龙徐家围子深层火山岩储层水平井测井评价存在的难点,采用地质导向技术,确定了水平井井眼轨迹与地层位置关系;建立了基于井眼轨迹与地层位置的水平井火山岩储层测井资料逐点校正方法;形成了水平井层界面识别、有效储层划分、岩性识别、储层参数求取及流体性质识别的水平井火山岩储层评价技术,形成了一套火山岩储层水平井测井校正方法。并推出井眼轨迹计算方法,从而指导地质导向。
[Abstract]:The middle basic volcanic rocks of Yingcheng formation in Xujiaweizi fault depression are widely distributed, generally contain gas, and have huge resource potential, but they have great buried depth and poor physical properties of reservoir, so we need to obtain better productivity by sidetracking horizontal wells in old wells or drilling new horizontal wells. Of the 200 billion square proven reserves in the deep layers of the northern Songliao Basin, a large proportion of the reserves need to be developed by horizontal well technology. This paper is aimed at the anisotropy of volcanic strata. Due to the difference of logging response between horizontal well and vertical well, the evaluation technology of volcanic rock in vertical well can not be applied to the evaluation of horizontal well data, which makes the logging interpretation accord rate low. In view of the difficulty of logging evaluation of horizontal well in deep volcanic rock reservoir of Xujiaweizi deep layer in Gulong, the relationship between horizontal well trajectory and formation position is determined by geological guidance technology. A point-by-point correction method of horizontal well volcanic reservoir logging data based on borehole trajectory and formation location is established, and the horizontal well interface recognition, effective reservoir division, lithology recognition are formed. The evaluation technology of volcanic rock reservoir in horizontal well based on reservoir parameters and fluid property identification has formed a set of logging correction methods for horizontal well of volcanic rock reservoir and the calculation method of borehole trajectory has been deduced to guide geological guidance.
