查询词典 well drilling

Based on seismic, well logging, drilling and core data, five super sequence boundaries have been identified by using methods of sequence stratigrphy theory in deep formations of Shengping area, northern part of Songliao basion. They are the top boundaries of bed rock (SSB1), the bottom boundaries of Shahezi group (SSB2), the bottom boundaries of Yingcheng group (SSB3), the bottom boundaries of Denglouku group (SSB4) and the bottom boundaries of Quantou group (SSB5) respectively.

应用层序地层学基本理论，在综合分析工区地震、测井、岩心等资料的基础上，确立了超层序界面、准层序和准层序组识别标志，进而对松辽盆地北部升平地区深层进行超层序界面识别，共识别出五个超层序界面，分别为基岩顶面(SSB1)、沙河子组底面(SSB2)、营城组底面(SSB3)、登娄库组底面(SSB4)和泉头组底面(SSB5)。

首先利用在钻井过程中随钻测量起钻后地面回旋的方法，自行研制开发出能够抗180℃高温，具有抗震功能的测量仪器；其次，在原有模型基础上，利用实例数据进行分析，考虑固相和多相流加速度压降的影响，研制开发了流钻欠平衡钻井环空多相流井底压力的计算模型，并推导出机械钻速影响井底压力增量的计算公式；最后，为验证模型精度，开发了钻井监测与分析计算软件，软件计算结果与实测数据叶比，误差小于3%。

Firstly, variables which were acquired for the above two kinds of classification system were obtained from field and laboratory investigation of the core samples as well as test of supersonic waves in drilling holes. Secondly, distribution functions and parameters of all variables are determined using statistic method. Thirdly, 20000 RMR values or BQ values and cumulative distribution function of these RMR or BQ values have been obtained utilizing Monte—Carlo method and the results are plotted. Finally, risk analysis can be made from above results.

风险评价方法步骤如下：（1）首先通过岩芯样品的现场观测和实验室试验及钻孔岩体超声波测试获得两种分类所需的变量；（2）通过统计分析和判断得出各变量的分布函数及参数；（3）运用Monte—Carlo模拟方法获得2万个RMR值或BQ值及相应的累积分布函数，并将结果绘成岩体质量描述图；（4）运用以上结果作出岩体质量风险分析。
