环亚国际娱乐app下载塔河缝洞型油藏从2006年开始应用示踪剂评价井间连通性,各类现场应用示踪剂本底浓度逐年提高,常用的示踪剂地层本底浓度已逼近最低检测浓度的30%,随注水采油的快速推进,工区内储备的5类常用示踪剂必将难以满足现场的持续需求;此外,现用的示踪剂全为外单位引进,我方示踪剂的详细成分不了解,对检测设备、检测精度和结论难以有效把关,因此有必要开展新型示踪剂研发,全面评价新型示踪剂性能,掌握具体的检测技术,提高示踪剂技术的现场应用价值。

Products>>Project Development>>Evaluation experiment of water-soluble fluorescent tracer in fracture-whole model

Tahe fracture-hole reservoir has been using tracer to evaluate cross-well connectivity since 2006. The background concentration of all kinds of tracer used in the field has increased year by year, the formation background concentration of the commonly used tracer has approached 30% of the minimum detection concentration. With the rapid progress of water injection and oil recovery, the five types of commonly used tracer in field will be difficult to meet the continuous needs of the demand. In addition, all the tracer used are imported from abroad companies, the composition of the tracer is not clear, so it is difficult to check the equipment, detection accuracy and output. Therefore, it is necessary to carry out the research and development of new tracer, comprehensively evaluate the performance of new tracer, obtain the specific detection technology and improve the field application of tracer technology.

环亚国际娱乐app下载Synthesis technology of water-soluble fluorescent tracer. The specific contents include the structure design of water-soluble fluorescent molecules, the design of synthesis route and the establishment of specific laboratory synthesis methods.

Synthesis technology of water-soluble polymer fluorescent microspheres tracer. The specific contents include the design of fluorescent polymer microspheres, the laboratory synthesis methods, and the water solubility control of fluorescent polymer microspheres.

Formula of fluorescent tracer, including the concentration of tracer molecules in the formula of fluorescent tracer, the distinction of fluorescence emission, and the thermal stability control technology of tracer.

环亚国际娱乐app下载Fluorescent microspheres have very important applications in many fields because of their stable morphology and high luminous efficiency. In this project, monodisperse water-soluble fluorescent microspheres were prepared by in situ dispersion polymerization called “one step method” from the point of view of improvement of methods. The effects of fluorescence properties and compatibility of fluorescent materials and monomers on the doping content of monodisperse water-soluble fluorescent microspheres were studied, and a series of fluorescent microspheres used as tracers were developed.

环亚国际娱乐app下载In the course of implementation, the temperature stability of fluorescent microspheres, the stability of pH and the influence of underground well environment will be deeply investigated according to the special needs of tracer. The results are fed back to the preparation process, and the properties of fluorescent polymer microspheres were improved according to the requirements of tracer by adjusting the preparation conditions (including reaction conditions and reactant formulation, etc.). Therefore, the tracer produced by the experiment has strong and advanced technology, and there are no similar products in China.
