对渤海BZ19-6区块变质岩潜山数口钻井的铸体薄片、常规物性等数据展开综合分析,依据矿物组成和岩石结构、构造等建立该区块变质岩的岩性划分方案。研究结果表明:除黑云二长片麻岩、黑云斜长片麻岩和黑云钾长片麻岩外,其余变质岩的浅色矿物(石英、长石为主)含量均较高,暗色矿物(黑云母等)含量较低;有效储集空间主要为构造运动产生的未充填裂缝和斜长石的粒内溶孔;当石英含量为25%~35%(体积分数)、斜长石比率为0.4~0.6时,物性最好;碎裂岩、二长片麻岩、二长混合花岗岩、斜长混合花岗岩的浅色矿物含量高,孔隙度和渗透率高,是形成优势储层最有利的变质岩岩性。但是,各岩性之间的浅色矿物含量、物性、抗压强度等相差不显著,指示岩性确实起到基础作用,但是构造作用可能是有利储层形成最主要的控制因素之一。

渤海油田潜山储层岩性多样、地质条件复杂、非均质性强,传统机械比能模型对潜山储层储集性能响应的敏感性较差,难以高效指导勘探作业决策。为此,基于微钻头钻进实验和滑动窗口理论,分析了机械比能对工程参数的响应规律,构建了机械比能标准化模型和改进型机械比能模型,形成了潜山储层储集性能解释标准。结果表明:渤海油田潜山储层钻压系数为0.309~0.605;改进型机械比能小于0.80时为Ⅰ、Ⅱ类储层,改进型机械比能为0.80~1.15时为Ⅲ类储层,改进型机械比能大于1.15时为致密储层。研究成果在渤海油田36口潜山探井作业中进行了应用,储层储集性能解释符合率平均值为80.2%。该研究可为中途测试、完钻等勘探作业决策提供技术支持,具有很好的借鉴意义。

随着渤海油田勘探开发的不断深入,潜山地层蕴含的石油储量已成为重要的储量增长点。潜山岩性复杂多变,非均质性强,变质岩潜山尤为明显。由于井场岩屑相对细碎,无法观察出岩石原貌,且当前还没有被普遍认可的元素与岩性之间数据关联或规律,使得应用元素录井数据识别变质岩潜山岩性成为难题。应用数据降维及随机森林两种算法,对元素录井数据进行降维处理和岩性判别建模,建立基于元素录井数据的变质岩潜山岩性判别模型,对研究区13口井的变质岩潜山岩性进行了判别。结果表明,岩性识别准确率由60.0%提高到86.5%,实现了对变质岩潜山岩性的有效智能识别。
