前言凉高山层的储油性质,不少同志先后进行过研究。有从电性上去探讨;有从裂缝上下结论;有从油层物理参数上去研究;也有从试采资料上去探索。各家均有不同的看法,有不同的解释。 构造上的许多钻井,没有取心,或取不上心,因此,直观的岩性研究法就有一定的困难。或者,有取心的油井,其储油参数与实际情况是两回事。因此,笔者试图从泥浆返上的岩屑(经过选择和剖面校对的岩屑)制成薄片,利用岩石偏光显微镜作直观研究。在谈及岩性对储油的优劣时,是从岩性出发接合试采资料的。 经过几个月的时间,通过十九口井的三百多个薄片观察,把工作心得写出来,重要的是希望得到指正和批评。
Preface The nature of oil deposits in the cool, high mountains has been studied by many comrades. Have to explore from the electrical; there are conclusions from the fracture up and down; from the physical parameters of the reservoir up to research; but also from the trial mining data to explore. Each has a different view, with different interpretations. Much of the structural drilling is either coring or out of focus, so there are some difficulties with the intuitive lithology method. Or, there are coring wells, the oil storage parameters and the actual situation are two different things. Therefore, the authors attempted to make thin slices of cuttings (cuttings of selected and sectioned proofs) returned from the mud and visualized using a rock polarized microscope. When it comes to the pros and cons of lithology for oil storage, it starts from the lithology and joins the pilot mining data. After months of observation, through the observation of more than 300 sheets of 19 wells, I was able to write down my work experience. What is important is that I hope it will be corrected and criticized.
