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。
