井口

Let's assume a two-foot square opening and a ledge width of 1-1/2 inches.

让我们假设井口有两英尺见方，井缘宽度1-1/2英寸。

By analysising cost and output for low yield oil wells, in the paper, the method of flow switch is used to judge if the well bore has the oil flows, which change the traditional experienced method (touch the beam hangers temperature and look if it has the oil film) and the present automatic liquid level monitoring manner, and it is the closed-loop control and reduce the intensity of labour and the cost of the production. The hill-climbing mathematical method is considered as the most effective way.

论文中采用了流量开关的方法判断井口是否出油，打破了传统用经验判断(看抽油杆是否发热、是否附有油膜)的方法和现有的自动液位监测仪判断方法，形成了闭环控制，降低了劳动强度和减少了生产成本；并将数学方法上的瞎子爬山法用在了本优化控制系统中。

落地式多绳摩擦提升机更换罐笼工艺复杂，施工方法主要由固定东侧罐笼钢丝绳，摘西罐底尾绳并固定，将西罐与悬挂装置脱开，拉出西罐，新罐笼进入井口，新罐笼与悬挂装置、尾绳连接，新罐笼改由提升绞车牵引，解除东罐笼钢丝绳的约束，试运行等步骤组成。

It just means you'll set them lower and give the stock more room to move around before you trade out of it.

只是因为你'剑下，给他们定房间走动股市更在你的贸易出井口。

Steam pipe line as one of the main facilities which is used in the steam line system of the thermal production ,the main reason for the decline of well head steam quality, the key factor of the decreasing energy efficiency .

输汽管道作为热采输汽系统的主要设备之一，是井口蒸汽干度降低的主要原因，也是降低能量利用率的重要因素。

In order to make the right evaluation of the state which is the consumption consume of the steam line system, we make an test of the heat loss of the steam line network. And we also probe into the heat loss of the steam line system and the factors. In order to solve the heat inefficency of the steam line system, we look into the present situation of the steam line network and the state of heat preservation. Then we found the open questions and the weak points of heat preservation. We make the evaluation and affirm the reason of the heat inefficency of the system. We adopted the combination of bench test and engineering optimization, then we screened out high-quality adiabator, and designed the best heating composition. We designed and developed the software"The analysis and optimization of energy of the steam line system in thermal production" It can offer convenience to the computational analysis of heat loss of the steam line system. It can also be used for design calculation and experimental verification of steam pipeline feasible radial-radius, so it can offer technical support for the reduce of heat loss of the system, the raise of well head steam quality and the raise of heat efficicency of the steam injection system.

为了对输汽系统的用能状况作出正确的分析评价，对输汽管线热损失进行了测试计算，对输汽系统热量损失及影响因素进行了探讨；为了解决输汽系统热效率低的问题，从输汽管网现状及管道保温状况调查入手，掌握存在的问题和保温薄弱环节，做出分析评价，确认导致系统热效率低的原因，采用室内试验与工程优化相结合的办法，筛选出优质保温材料，设计最优保温结构，同时设计开发了&热采输汽系统能量分析及优化软件&，为输汽系统热量损失计算分析和保温结构优化提供了方便，还对输汽管线合理辐射半径进行了设计计算及实验验证，从而为降低系统的热能损失，提高井口蒸汽干度，提高注汽系统的热效率提供了技术支持。

Before the pitcher is shattered at the spring, or the wheel broken at the well.

瓶子在泉旁损坏，水轮在井口破烂。

6Remember him-before the silver cord is severed, or the golden bowl is broken; before the pitcher is shattered at the spring, or the wheel broken at the well

12：6 银链折断，金罐破裂，瓶子在泉旁损坏，水轮在井口破烂

The results of tests show that the technology pipe string is advanced and reliable and has an obvious social and economical benefit.
