Our PumpMate multi-function well head controller is equipped for a wide range of uses, whether the application is for a basic, reliable well intermitter or a full feature, automated well control system.

我们的PUMPMATE 多功能井口控制器使用很广泛，不管是应用于基本的，可靠的井间歇气举控制器，还是全功能的，自动井控制系统。

The problems encountered in deepwater well cementing are low temperatures of boreholes,narrow gap between pore and fracturing pressures in formations,high susceptibility to fluid intrusion,and creation of interzonal channellings.

本文讨论了深水固井中存在的问题：固井温度一般比较低；地层孔隙压力和破裂梯度之间的窗口比较窄，地层易漏；容易发生水、气窜等。

A method of velocity tomographic inversion based on Fermat principle is presented by using travel times of transmitted waves from one borehole to another.

利用井间透射波旅行时，给出了一种以费马原理为基础的井间地震弯曲射线速度层析成象方法，数值计算表明了该方法比直射线法反演成象精度高。

Based on the 3-D acoustic equation and Tarantola′s generalized inversion theorem, taking into consideration the character of cross-well survey, a 2.5-D cross-well waveform tomography method in the frequency domain is presented here.

从频率域3-D声波波动方程出发，结合井间观测方式的特点，基于Tarantola广义反演理论，提出了一种频率域2.5-D井间波形层析成像方法。

For sustainable utilization of water resources, development of systems of well irrigation with well drainage and canal irrigation with ditch drainage was needed.

为水资源的可持续利用，要发展井灌井排渠灌沟排，以开发利用当地浅层地下水包括微咸水和咸水为基础，以引调可利用的地表水补源。

In the controlling over water irruption flooding of main shaft in Dougguashan copper mine, the author makes an introduction to an application of gravity high pressure grouting system in the grouting on the working face of shaft floor.

本文介绍了在冬瓜山主井突水淹井治理过程中，深井自溜高压注浆系统在井底工作面注浆中的应用。

When processing of data from single-point test, the value of α is generally taken by 0.25 for calculating the open flow potential of gas well, and the result is far from that from modified isochronal test.

目前，在处理一点法试井资料时，取函数α为定值0.25来计算气井的无阻流量，其结果与修正等时试井有很大的偏差。

Moreover, the modified isochronal test should be based on the principle that the flow rate is determined by the physical properties of reservoirs.

进而指出修正等时试井的适用范围，提出了修正等时试井应该根据储层物性确定测试流量的原则。

To resolve the problem, based on backpressure test theory and superposition principle, this paper designed a new test method, named Backpressure Isochronal Test.

以回压试井理论和渗流叠加原理为基础，提出了"回压等时试井"产能评价方法，该法所需测试时间与"单点法"大致相同，但能较准确地评价低渗气井产能。

Based upon the above causes, taking the Hongmiao colliery"coal bed 5-1 south working face conveyance laneway on Sector 5 of Pit 2"for the project example, it can be known through primordial rock stress test result that Sector 5 of Pit 2 belongs to high-stress area, whereas wall rock is a class V terrane with terribly labilization.

基于上述原因，以红庙矿"二井五采区5-1煤层南一工作面运输巷道"为工程实例，通过原岩应力测定成果可知，二井五采区属于高应力区，围岩属于V类极不稳定岩层。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
