摘要: 针对胜利油田渤南洼陷浊积岩油藏水平井钻井中存在的井壁易失稳、滑动摩阻大、携岩困难等问题,通过线性膨胀试验评价了有机胺的抑制性,通过高温高压滤失试验评价了"原油+极压润滑剂"的封堵效果,并分析了原油加量对钻井液流变性和润滑性的影响规律,最终研制出高混油有机胺聚磺钻井液。室内研究表明,高混油有机胺聚磺钻井液的抗温性、流变性及抑制性好且性能稳定、润滑性能优良,可以达到现场要求。该钻井液在渤南区块应用了9口井,均未出现井壁坍塌和黏卡事故。其中,义123-9HF井三开井段平均井径扩大率5.8%,三开水平段钻进摩阻保持在60~80 kN,显示出良好的抑制防塌和润滑性能。由此可见,高混油有机胺聚磺钻井液可有效解决胜利油田渤南洼陷浊积岩油藏长水平段水平井钻井中存在的问题,也可为同类储层的提速钻进提供新的技术支持。Abstract: To address problems such as hole instability, high sliding friction and poor cuttings transport encountered in drilling horizontal well in a turbidite reservoir of the Bonan Depression, Shengli Oilfield, the inhibition of organic amine drilling fluids was evaluated by linear expansion test in laboratory, the plugging effect of both"crude oil and extreme-pressure lubricant" was evaluated by a HTHP filtration experiment.Then the effect of the oil content on drilling fluids performance was also evaluated, by which an organic amine sulphonated polymer drilling fluid containing a high content of crude oil was developed.Lab test results demonstrated that organic amine sulphonated polymer drilling fluids with high contents of crude oil possess satisfactory temperature tolerance, rheology, inhibitive behavior, lubricity and stable performance, which can meet field requirements.This drilling fluid system has been applied in 9 wells in Bonan Block, with no hole collapse or pipe sticking.Typically in Well Yi 123-9HF, the average hole enlargement rate at the third spud section was 5.8%, the friction at the horizontal section remained at 60-80 kN, which demonstrates the good hole collapse prevention ability and the lubricity of the drilling fluids.Therefore, organic amine sulphonated polymer drilling fluids with high contents of crude oil can effectively resolve problems in drilling horizontal wells in a turbidite reservoir of the Bonan Depression, Shengli Oilfield, and provide new technical support for raising penetration rate in drilling similar reservoirs.
