查询词典 well drilling

Before target-entering into a horizontal well or in the process of drilling horizontal section,to confirm the controlling range of deviation angle and azimuth of hole section is not only an important measure to guarantee target rate and trajectory control accuracy of the horizontal well but also one of the important contents in trajectory supervision of the horizontal well.

在水平井入靶前或水平段钻井过程中，确定待钻井段井斜角和方位角的控制范围是保证水平井中靶和轨迹控制精度的关键，也是水平井井眼轨迹监控的一项重要内容。

Currently, in the oil-field exploitation, existing the phenomenon of garbling the lack thickness of stratum with vertical fault-throw in well logging identification of strata while meeting fault in drilling well. In most case, consider the lack thickness of stratum which contrast the imperfection geologic strata thickness to the well and the well as the fault-throw. The method which using very popular in oil-field exist shortages, it very much easily lead people into the areas of misplay. especially when the seismic person and geology confirm the fault-throw, It often appear inconsistent instance.

目前，在油田开发中钻井钻遇断层时，地质人员时常存在将测井分层与相邻井对比时缺失地层厚度与铅直地层断距混淆的现象，很多情况下把井与井对比缺失地层厚度等同于断层断距等，这些现今在油田非常流行的用法存在一些不足之处，容易把人们引入一些认识上的误区，特别是在地震与地质人员进行断层断距的确定时，经常出现矛盾的情况。

During drilling well, keeping wellbore stability is very important for drilling normally.

在钻井过程中，保持井眼稳定性是保证正常钻进的基础。

Natural gas drilling, as well as oil drilling, has scaled back significantly in recent months.

天然气开采，以及石油钻井，大大缩减了近几个月。

It is expected that hot melt drilling method have a good application prospect in drilling engineering, particularly in well cementing without casing.

热熔钻进工艺在无套管固井和工程施工中有很好的应用前景。

Unbalanced state was kept at the bottom of the well by downhole casing shut-off valve in whole process unbalanced drilling operation, the oil reservoir was protected by unbalanced drilling and non-snubbing service.

在全过程欠平衡钻井作业过程中，通过井下套管阀开关，保证井底始终处于欠平衡状态，成功地进行了欠平衡钻进、不压井起下钻等作业，有效地保护了储层。

In the process of the oil and gas field's exploration, when the well contains a great amount of supercritical fluid such as CO2 and H2S, the well blowout, erosion, wax problem and scale problems will take place more frequently. In the process of drilling, when the supercritical fluid emerged by conventional natural gas changes in phase transition, the well blowout will happen.

在油气田的开发过程中，井筒内高含CO2、H2S的超临界态流体，加速油井管柱的腐蚀、结蜡、结垢、灾难性的突发事故的出现；在钻井过程中，气侵的超临界流体在环空相态变化将可能引发钻井井喷。

It is known that exact calculation of formation pressure is significant not only for the proper and costeffective selection of drilling fluid properties, but for the prevention of drilling problems like blowouts, lost circulations and well caving.

地层压力的准确计算对于合理、经济地选用钻井液性能，防止井喷、井漏、井塌等复杂钻井情况的发生具有重要意义。

There is big difference between horizontal well logging while drilling and wireline directional well logging, and different logging response characteristics have become a new challenge for the welldeveloped wireline well logging interpretation.

水平井随钻测井和直井电缆测井具有较大差别，不同的测井响应特征对已比较成熟的电缆测井解释方法提出了挑战。
