FV-1清蜡降粘剂研制与应用

针对Ｘ断块中间基原油（Ｉｎｔｅｒｍｅｄｉａｔｅ—ｂａｓｅｃｒｕｄｅｏｉｌ）在开采过程中出现光杆下不去，抽油机负荷增加，启抽困难，甚至不能启抽，回压升高或集输管线堵塞等问题；在分析原因的基础上，依据原油清蜡、降粘机理，应用６０多种药剂进行了以溶蜡速度、降粘率、降凝率、防蜡率为因子的４因素和４水平正交试验；研制出了高效、多能的ＦＶ－１清蜡降粘剂。这种清蜡降粘剂具有溶蜡速度快，降粘率高，防蜡效果好等特点，现场使用效果显著。

Development and Application of FV-1 Paraffin Thinner

During the process of inter mediate-base crude oil production in X fault block, there is a series ofproblems existed, such as polished rod can't run down, load on beam unit load increases and difficult to start andhigh back pressure, gathering line plugging etc. On the basis of cause analysis, according to mechanism of waxremoval and viscosity reduction, highly efficient, multifunctional FV-1 paraffin thinner is developed. The paraffin thinner has advantages of quick wax dissolution, high paraffin thinning capability and gOOd wax inhibition. Itsoil/water separation speed can meet the requirement of heat setting process unit and its field application resultsare very outstanding.
