油井

BEIJING, May 18 Xinhua, according to Singapore's "Lianhe Zaobao," reported the British oil company Gulf Harbour oil spill blocking some progress made , engineers plugged the day before yesterday in the oil spill oil on a straw, which began sucked part of the oil spill ...

中新网5月18日电据新加坡《联合早报》报道，英国石油公司封堵墨西哥湾海底漏油工作取得一定进展，工程人员前天在漏油油井上插上一只吸管，开始吸走其中的一部分漏油。。。。

The intensity of the ultrasonic wave will increase when the ultrasonic wave is focused by the sound lens in rock stratum.

然而 ，这种方法要受到两个因素的制约：一是增大超声换能器的功率，必然要增大超声换能器的尺寸，这在本身尺寸就很小的油井中是有一定限度的；二是当超声换能器辐射出的超声波的强度过大时，在超声换能器的周围要发生强烈的空化现象，产生大量的气泡，这些气泡将对超声波产生强烈的散射作用，导致超声波的衰减，反而降低超声波在岩层中的传播距离[1] 。

Based on the practice of the use of φ95mm subsurface sucker rod pump in Shengtuo Oilfield in recent years, the causes of the failure of the pump are analyzed, and relevant precautions are put forward:(1)selecting oil wells with sufficient fluid supply for pumping;(2)under the condition of the pump efficiency being the same, the submergence depth of the pump being somewhat larger than that of the small pump, and 450～500m being feasible;(3)adopting Grade H ultrahigh-strength rod string and fixing a sinker bar at the bottom of the rod string;(4)selecting long stroke and low pumping speed, and more than 5m stroke and less than 6min-1 pumping speed being recommended;(5)adopting zirconium oxide valve ball and seat ＋ spray welded plunger ＋ nitrided barrel.

根据胜坨油田近几年采用φ95mm有杆抽油泵提液的实践，分析了造成这种抽油泵失效的原因，包括与其配套的脱节器失效、抽油杆断脱、泵漏、电动机不配套和生产管理不善等。为增强泵的提液能力和工作可靠性，提出5 项预防措施：(1)选择有充足供液能力的油井；(2)在保持相同泵效的情况下，泵的沉没度应略大于小泵，推荐按450～500m设计；(3)采用H级超高强度抽油杆柱，并在杆柱底部配置一定重量的加重杆；(4)采用长冲程、低冲次的参数匹配，推荐光杆冲程大于5m，冲次小于6min-1；(5)为提高泵筒、活塞和阀座的防腐耐磨性，推荐采用&氧化锆阀球和阀座+喷焊柱塞+氮化泵筒&的结构形式。

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。

Metal surface heat treatment, electroplating, spray before the cleansing, extraction, transportation, refining, and oil pipelines, storage tanks, tankers, etc. grease, wax scale, coal tar, asphalt, such as cleaning.

金属表面热处理，电镀，喷漆前清洗，采油，输油，炼油，及油井输油管，储油罐，槽车等的油垢，腊垢，煤焦油，沥青等清洗。

Therefore a GD sand-screening pipe is developed, which is helpful to the environment protection. This new sand-screening pipe consists of center pipe, sand filter and guide shoe. The center pipe is machined from 64mm tubing, and the sand filter is made from silica sand, cement, additive.

这种环保型滤砂管由中心管、滤砂器及引鞋组成，中心管采用 6 4mm油管加工而成，两端为特种 6 4mm平式油管螺纹，管体上每米均匀分布 72个直径 10mm孔眼；滤砂器是根据不同技术标准筛选不同粒度的石英砂、油井水泥、添加剂和水按配比加工压制的。

The formation sand flow is one of an important factor to effect the nonnal production of oil wells. Sand pump technology is an effective way to control the fine sand in the artificially lifted wells. Sand control pump is main tool for sand disposal.

地层出砂是影响油井正常生产的重大因素之一，排砂工艺是针对细粉砂在机采井上采取的一种防砂工艺，防砂泵是目前主要的排砂工具。

Some say the man looks like he's wearing earphones; that's merely a road and an oil well.

一些人表示，这个人看起来好像带着耳机，但事实上那是一条公路和一口油井。

There are many oil wells in that area.

在那个地区有许多油井。

At present, three oil wells in the area have been successfully implemented and has achieved good results.

目前该区已有三口油井顺利实施，并且都取得了较好的效果。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
