  聚合物的分布
     In order to study polymer distributing law after polymer flooding and the feasibility of polymer recycle,two three-dimensional anisotropic models of 50×50×10 cm were designed. One of the models had a clapboard to simulate the polymer distribution under multi layers condition,and one model had no clapboard to simulate polymer distribution under a single oil-bearing layer. The rule of polymer adsorption post polymer flooding was studied by analyzing the gross polymer production volume and absorption volume.

Objective This study was aimed to visualize the polymer distribution within the microspheres, to localize the encapsulated drug, and to evaluate the potential of confocal laser scanning microscope(CLSM)as a characterization tool for microspheres. Methods Microspheres were prepared by complex coacervation. Model protein drugs(BSA) and polymers (gelatin and arabic gum) were covalently labelled with a fluorescent marker prior to microsphere preparation. By applying CLSM, the polymer distribution or changes in polymer matrix composition under the influence of the drug were visualized, and three-dimensional reconstruction and image analysis of the microspheres were performed by scanning different coplanar sections throughout the object. Results A homogeneous distribution of both gelatin and arabic gum throughout the microspheres was observed. The addition of fluorescently labeled BSA as a macromolecular model compound to the coacervate resulted in a homogeneous distribution of BSA within the microspheres; concurrently, the distribution of gelatin and acacia indicated that their deposition was not influenced by the presence of BSA-FITC. Conclusion CLSM allows the inspection of internal microsphere structures without prior sample destruction. It can be used to localize the encapsulated compounds and to detect special structural details of the microsphere composition.

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry ( MALDI-TOF MS) is a newly-developed platform especially suitable for accurate weighing and structural analysis of biomolecules. It is characterized by high sensitivity, high accuracy, inherent simplicity, broad mass detection ranges, high resolution and low sample consumption. This technique is extensively used in verifying sizes and purities of biomolecules, such as peptides, proteins, oligonucleoti-des, and polysaccharides, investigating higher order protein structures (molecule interactions, con-formational differences in allosteric proteins and posttranslational modifications) , identifying sequences of proteins and oligonucleotides and assaying macromolecule polymer distribution ranges.

Re-use of retained polymer underground is a new method of enhanced oil recovery(EOR) after polymer flooding.Based on oil-water two phases network simulation model,the microscopic simulation model for polymer flooding was provided together with polymer seepage mechanism.Laws of retained polymer distribution and its influence factors were studied by microscopic numerical simulation,which can provide necessary information for EOR after polymer and proper re-use of retained polymer underground.Simulation results indicate that retained polymer occupies 61.7% of injected polymer because of polymer retention in pore/throat due to absorption and(or) entrapment.The amount of retained polymer in larger pores is larger while with smaller polymer concentration.Pore/throat radius and shape factor are main factors that can influence polymer's retention.The concentration of retained polymer located in pore /throat presents inverse ratio to the product of pore/throat radius and shape factor's square root.

再利用地下滞留聚合物是聚合物驱之后进一步提高原油采收率的新途径。基于油水两相流网络模拟模型,综合考虑聚合物渗流机理建立起聚合物驱微观模拟模型。用微观数值模拟手段研究了地下滞留聚合物分布规律及影响因素,为有效地开采聚合物驱后剩余油、合理利用滞留地下聚合物提供必要的依据。模拟结果表明,由于吸附和捕集作用将引起大量聚合物滞留在孔喉中,滞留聚合物占注入聚合物的61.7%。总体上看,大孔喉中聚合物滞留量较大,但滞留聚合物浓度较小。孔喉半径和形状因子为聚合物滞留的主要影响因素,孔喉滞留聚合物浓度与孔喉半径和形状因子平方根的乘积成反比。
