随着油田采收率的不断提高,勘探难度越来越大,以前不作为重点的0.5m的薄储层逐渐受到重视,而从国内外测井技术来看,薄层(0.5m-1m)和超薄层(<0.5m)的划分及解释一直是各个测井公司的难点,而我们油田也有类似情况,许多不能划分和解释的薄层和超薄油层白白丢掉,每年因此而损失的储量也是巨大的,薄层侧向测井仪正是为了解决这个难题而在原来三侧向基础上改进研制的新型薄层测井仪器,主要用来测量地层侵入带及原状地层的电阻率。为了提高新型薄层测井仪器的纵向分辨率,更精确的划分油气水层,我们采取了以下措施。
With the continuous improvement of oil recovery, exploration is more and more difficult. As a result, there is a growing emphasis on the 0.5m thin reservoirs that have not been prioritized. According to the logging technology at home and abroad, thin layers (0.5m-1m) And the thin layer (<0.5m) division and interpretation has been the difficulty of logging companies, and we also have a similar situation in the oil field, many can not be divided and explained the thin and thin reservoirs in vain lost, so each year the resulting loss of reserves It is also great that the thin lateral logging tool is a new thin-layer logging tool developed on the basis of the original three-lateral method to solve this problem. It is mainly used to measure the resistivity of the stratigraphic intrusion zone and the original formation. In order to improve the vertical resolution of the new thin-layer logging tools and to more accurately partition the hydrocarbon layer, we have taken the following measures.
