某区块主要储层为F油层,岩性为砂泥岩,厚层较发育,但沉积类型复杂。对应这样的储层,油水层识别存在很大困难。为了进一步搞清本地区的油水层分布规律,提高解释精度,因此,本文通过储层测井曲线值的响应特性,建立了油层、油水同层和水层的油水关系判别图版,一改往日的只产油或水,不油水同出的观点。通过这一尝试,把这一解释方法应用到该区的测井解释当中,取得了较好的效果。
The main reservoir of a block is F oil layer, lithology is sandstone and mudstone, thicker layer is developed, but the sedimentary type is complex. Corresponding to such reservoirs, oil-water layer identification has great difficulties. In order to further clarify the law of oil and water distribution in this area and improve the accuracy of interpretation, this paper establishes the oil-water relational discrimination map of oil layers, oil-water layers and water layers based on the response characteristics of well logging curve values. Only oil or water, not oil and water with the point of view. Through this attempt, this interpretation method is applied to log interpretation in this area, and achieved good results.
