By systemic researching and simulating experiment, the text gains such results as follows,1. On the base of sufficiency research on the oil-gas hydrocarbon systemic chemistry composing and the physical chemistry characters, we traverse the mechanism of the paraffin's deposition. Then we consider that paraffin deposition is a complex process ofphysical chemistry, which includes more than one single mechanism.2. Traversing and comparing the literature in detail on different factors that has effect on paraffin deposition, the available experimental methods on paraffin deposition, prevention of paraffin deposition, and removing of the deposited paraffin on the spot.3. Ameliorated the laser equipment of solid particle inspecting system and the corresponding test methods. Determine WCT of dead oil and live oil from KS101 well under different pressure with this system. The result implies that dead oil has opposite regulation on paraffin deposition temperature to live oil.4. A vapor-liquid-solid envelop is drawn by superposition regular vapor-liquid envelop and WCT curve thereby explained that the departure and quick raising of the curve in the low temperature zone is caused by the appearance of paraffin in solid phase.5. Estimation is made to determine the depth of paraffin deposition in the well.

通过系统的研究和实验模拟，本文取得了以下研究成果：(1)在充分调研油气烃类体系的化学组成及其物理化学特征的基础上，详细研究了石蜡沉降的机理，认为石蜡沉积是一个复杂的物理化学过程，是多种机理共同作用的结果；(2)深入调研并综合阐述了影响石蜡固相沉积的各种主要因素，对目前国内外常用的有机固相沉积实验研究方法和现场清防蜡措施也做出详尽的描述，并加以对比评价；(3)改进了油气藏开发重点实验室自行研制组装的高温高压下测定固相沉积的激光装置和测试方法，并用该套设备测定出柯深101井的井口脱气油样和凝析气平衡油样不同压力下的析蜡点，实验结果表明，脱气油和平衡油析蜡规律相反；(4)将常规气-液两相相图和析蜡曲线叠加得到了气—液—固三相相图，从而解释了气-液两相等液量线在低温区域偏离正常并快速上翘是由于体系有石蜡固相出现；(5)利用实验测试的析蜡温度预测析蜡位置，表明只有在距井口465m油管以上会有蜡析出。

Rigs can be supplied with a slant hole mast, hydraulic roughneck, power slips and the Schramm LoadSafe automated pipe handling system.

钻机能够装配倾斜钻进桅杆、液压井口大钳、井口液动卡瓦和雪姆全自动换杆系统。

I think that only the wellhead big blue sky at night, I like facing the wellhead few stars, up to count 20 different stars.

我认为，蓝天只有井口那么大，晚上，我喜欢对着井口数星星，最多能数出20颗不一样的星星。

Pteris nervosa L. were discovered and confirmed as another arsenic hyperaccumulator in field investigation, could accumulate arsenic up to 1000mg/kg in pinnate in field. P. vittata L. and P. nervosa L.

通过野外调查，发现和证实了大叶井口边草是一种As的超富集植物，并发现蜈蚣草和大叶井口边草对多种重金属都具有很高的耐性。

ABSTRACT :Parade car belonging to coal production system is an important part, it refers to the meaning of the wellhead, the bottom of the machinery, telegraph equipment in the closed conditions, in accordance with the logic of the design cycle process moves auxiliary cage complete upgrade mandate.

摘 要：矿井井口液压站设计，副井操车系统是煤矿生产中重要的一部分，它的含义是指井口、井底有关机械、电报设备在规定的闭锁条件下，按照设计的逻辑程序循环动作，辅助罐笼完成提升任务。

It is dangerous to walk anywhere near a shaft opening; the whole area is often ready and waiting to slide into the shaft, along with the curious.

在井口附近的区域走动是危险的，因为一般来说整个井口周围已经不那么牢固，行人很有可能会滑入竖井并受到惊吓。

It uses advanced completion pipe string and sand fracturing pipe string in completion process to attain the goal of layer fracturing and selective zone production of the parent well and its branch.

XQ90井是我国在川西地区所钻成的第一口气井分支井组，该井在完井工艺上采用了先进的完井管柱和加砂压裂管柱，达到了主、分支井分层压裂，分层开采的目的；其自行研制的双管采气井口可以分别控制主、分支井井口油压，为后期的采气作业提供了可靠的保障。
