The use of these drilling fluid systems meet the requirements of drilling engineering , and avoids the downhole troubles 这几种钻井液体系满足了钻井工程需要，避免了井下复杂情况的发生。
Drilling instrument is the major application to monitor and analyze the drilling process , making drilling more safe and rational 钻井参数仪表是钻井工程监测钻井过程、进行科学分析和科学决策的重要工具。
Drilling parameters instrument is the important implement to monitor and analyze the drilling process , and to make scientific decision - making about drilling process 钻井参数仪表是钻井工程中监测钻井过程、进行科学分析和科学决策的重要工具。
The team ' s rich experience also includes organizing and co - ordination of various production activities , complete control of the hse , quality , schedule and cost of welll drilling projects 在组织、协调各项生产活动方面，以及全面负责钻井工程的安全、质量、进度、成本等方面积累了丰富的经验。
Based on the successful application of mudlogging data analysis in evaluations of oil and gas beds , formation preessure and monitoring drilling engineering in the pushen well no . 1 , one of the key - wells of the daqing oilfield , the authors explain the importance of this mudlogging technique in exploration of oil and gasp and emphasize the significance of the technique for the exploration projects of oil and gas of similar category 摘要根据大庆油田重点预探井葡深1井录井施工过程中综合录井资料在评价油气层、地层压力检测和钻井工程监测等方面的成功应用，阐述了该技术目前在油气勘探中的重要作用，及对今后同类油气勘探项目建设的借鉴意义。
In production , the technology can provide geologic foundation for objective stratum to take core localization , the drill - stem testing , the well completion work , the well logging interpretation , the well drilling project breakdown processing , and coordinate with other logging methods to carry on the scientific appraisal to the stratum , and has been used widely in exploration and development in jianghan oil region 在生产实践中它能够为目的层取心定位、中途测试、完井作业、测井解释、处理钻井工程故障提供地质依据，并与其他录井方法和测井方法相配合，对地层进行科学化评价，在江汉油区油气田勘探开发中广泛运用。
Because of the merit of continuity , economical efficiency , reliability and high resolution , the well logging has shown its advantages , especially in some drilling engineering problem , such as the prediction of rock drillability , selecting the drill bit types , prediction of formation pressure , calculation the in - situ stress , evaluating the borehole walls stability and determining the reasonable mud density , and etc . aiming at the engineering accidents , for example the well spout , well leak , well collapse and the drill blocking during the drill engineering in the t formation in north - east of sichuan , some farther studies of formation pressure in feixianguan from well - logging information are presented in this dissertation 尤其是在岩石可钻性预测与钻头选型、地层压力预报、地应力计算以及井壁稳定性评价、泥浆密度安全窗确定等钻井工程问题上。测井技术由于连续性、经济性、可靠性及分辨率高等特点，越来越多地显示了其优越性。本文针对川东北部三叠系地层在钻井过程中遇到的井喷、井漏、井塌和卡钻等工程事故，主要对飞仙关组地层压力的测井解释方法作了大量的深入研究工作。
The " exploitation operations " means all the work on designing , construction , installation , drilling etc . , and the related research conducted for petroleum production from the approval of the overall exploitation program , including the production activities conducted prior to the beginning of the commercial production （六） “开发作业” ，是指自油（气）田总体开发方案被批准之日起，为实现石油生产所进行的设计、建造、安装、钻井工程等及其相应的研究工作，包括商业性生产开始之前的生产活动。
Drilling footage and cycle were regarded as two independent variables , while the drilling data accomplished by the changqing drilling engineering company were taken as samples , and then those two hypotheses were testified by the method of statistical analysis to set up a drilling cost forecast model with a strong explanation 构建了钻井进尺和钻井周期两个自变量，并以2003年长庆钻井工程总公司完成的钻井数据为样本，运用统计分析方法来验证这两个很设，并构建成本预测模型，该模型的解释力度较强。
