摘要

海上稠油热采井多为定向井或者水平井,井斜角大,注汽管柱在重力作用下会与套管内壁接触,导致注汽管柱尤其是隔热管接箍位置隔热效果变差,热损失大。为此,研制了一种新型隔热油管扶正器,并开展了隔热性能和耐温耐压性能检测。该扶正器主要由隔热机构、扶正机构以及固定机构组成。隔热机构采用复合隔热结构设计,确保隔热功能;扶正机构采用多组扶正块及组合圆柱型弹簧周向均匀排列结构设计,确保弹性扶正功能,保证管柱居中效果。室内性能检测表明:该扶正器耐温为350 ℃、耐压为21 MPa,隔热等级达到D级,且具有良好的遇阻收缩性能。现场应用结果表明:新型隔热扶正器保障了封隔器的坐封和密封效果,解决了海上热采水平井注汽管柱“躺壁”的问题,有效降低了井筒热损失,保护了套管与固井水泥。该技术可为海上稠油油田安全高效热采开发提供有力的技术支撑和保障。

Abstract

Offshore heavy oil thermal production wells are often directional or horizontal wells with large inclination angles. Under the influence of gravity, the steam injection string may contact the inner wall of the casing, leading to a decrease in the thermal insulation effect, especially at the thermal insulation coupling positions, and resulting in significant heat loss. To address this issue, a new type of insulated tubing centralizer was developed, and its thermal insulation and temperature-pressure resistance performance were tested. The centralizer mainly consists of a thermal insulation mechanism, a centralizing mechanism, and a fixing mechanism. The thermal insulation mechanism is provided with a composite thermal insulation structure designed to ensure thermal insulation functionality. The centralizing mechanism is designed with multiple centralizing blocks and combined cylindrical springs evenly distributed circumferentially, ensuring elastic centralizing functionality and guaranteeing the centralization effect of the string. Indoor performance tests indicate that the centralizer can withstand temperatures of 350 ℃ and pressures of 21 MPa, with a thermal insulation rating of Class D, and it also has good resistance to contraction when encountering obstacles. The site application results show that the new insulated centralizer ensures the seating and sealing effect of the packer, solves the problem of the steam injection string "lying against the wall" in offshore thermal production horizontal wells, effectively reduces the heat loss in the wellbore, and protects the casing and cement sheath. This technology can provide strong technical support and assurance for the safe and efficient thermal production development of offshore heavy oil oilfields.
