| 6. | The calculation results show that the jack - up platform under dynamic ice loads is in safe condition and can perform drilling operation in winter ice zone
计算结果表明，该平台的桩腿在冰激动载荷下的强度满足安全要求，冬季继续在冰区海域进行钻井作业是可行的。 |
| 7. | Through analysis on the study of drilling cost both at borne and abroad , the main factors influencing the drilling cost have been found to guide to build up the forecast model on the drilling cost
摘要通过对国内外钻井成本研究的分析，寻找影响钻井作业成本的主要因素，可指导钻井作业成本预测模型的建立。 |
| 8. | Therefore , a positive research method was adopted to put forward two hypotheses during the oil and gas drilling works , i . e , a certain relation existed between operation ' s cost and drilling footage and cycle respectively
为此，采用实证研究方法，针对油气钻井作业的过程提出两个假设：钻井作业成本与钻井进尺呈一定的比例关系；钻井作业成本与钻井周期呈一定的比例关系。 |
| 9. | The optimization of underbalance pressure drilling cycle medium and casing program and the complicated circumstances ( formation water out , sidewall stabilization and so on ) being able to occur in underbalance pressure drilling job were analyzed and investigated
在欠平衡钻井循环介质的优选、井身结构以及欠平衡钻井作业中有可能出现的地层出水、井壁稳定性等方面进行了分析和研究。 |
| 10. | Based on methods above , an applied program in visual basic is developed to interpret logging data and geosteering in drilling horizontal wells . the program guides to evaluate the oil field in a complicated geological situation and drill in horizontal well while it is applied to the work of interpretation and geosteering in the research zone
在上述方法研究的基础上，结合塔里木油田和莫北油田的实际情况，利用vb语言编制了一套随钻测井资料解释和水平井钻井地质导向的应用程序。将该程序应用于工区的随钻测井资料解释和水平井钻井的地质导向工作中，较好地指导了复杂地质条件下的油气藏评价工作和水平井钻井作业。 |
