Orthogonal experiment under special condition showed that modifier M has marked effect on properties of no bake sand. Other factors such as modifier B,phosphate concentration and aluminum hydroxide have some impact on properties of binder. It can be found by experiments that strengths of no bake sand are raised notably by binder that modified by modifier B. Modifier B can reduce the strength of no bake sand at high room temperature apart from condition of low room temperature that it can accelerate the reaction and strengthen the sand. Modest content of modifier M in binder has some improvement to anti-wettability of sand. But modifier B has not such notable effect. Electronic microscope shows that near cracks in no bake product there are fibrous shape substances formed when the samples are moistured in high humidity air for sometime.
通过改性剂B对粘结剂自硬砂的性能影响试验发现,改性剂B能显著提高粘结剂自硬砂的强度,在0℃左右很低的环境温度下改性剂M有利于提高自硬砂的反应速度和砂型强度外,但在较高环境温度下,改性剂M均降低粘结剂自硬砂的强度,但是适量的改性剂M有利于改善自硬砂的抗吸湿性,而改性剂B对于改善自硬砂的抗吸湿性的作用不如改性剂M明显,电镜观察发现抗吸湿性较好的自硬砂在高湿度下存放一定时间后,在粘结膜裂纹处会形成一种绒毛状物质,该物质对裂纹具有愈合作用,这种绒毛状物质中具有改性剂M中的某种成分,且含量很高,由此说明改性剂M对提高抗吸湿性有利。

Using maximum flooding surface and local explosure erosion surface as the correlation framework surface in the 4-th hierarchical base-level cycles, sand-body in the 3-th hierarchical base-level cycles formed in the 4-th hierarchical base-level cycles may be correlated layer by layer. The law of the sand-body and the characters of reservoir heterogeneity formed in the 4-th hierarchical base-level cycles are discussed. The study shows:①During early period of the 4-th hierarchical base-level cycle rising, subaqueous distributary channel formed, continuously stacked vertically, and migrated in limit range laterally, and channel sand-body stretches farther longitudinally, and lacks interbeds of mud rock and siltsand in sand rock, reservoir heterogeneity is relatively weak.②During mid-period of the 4-th hierarchical base-level cycle rising, subsaqueous distributary channel migrated actively, channel divided and converged strongly to form netted sand-body and sand sheet mainly, but interbeds of mud rock and siltsand increases gradually in sand-body, reservoir heterogeneity increased.③During later period of the 4-th hierarchical base-level rising and early period of the 4-th hierarchical base-level falling, reservoir sand-body was poor, and only form thin sand-body of subsaqueous distributary channel, subsaqeuous creveas and distal mouth bar, sand-bodys are surrounded by mud and silt rock.
进一步采用以第4层次基准面旋回中相当最大湖泛面的相转换面和具有区域性暴露侵蚀作用的层序边界面为等时地层对比框架的边界,对发育于MSC2—MSC4三个第4层次基准面旋回的第3层次基准面旋回内砂体进行了逐层等时对比,探讨第4层次等时地层对比格架内储集砂体发育分布规律,及储集砂体的非均质性特点,研究发现:①第4层次基准面上升初期发育的水下分流河道,砂体呈连续叠置、侧向迁移受限,纵向上呈长距离延伸的带状产出,砂体间泥、粉砂岩夹层少,储层非均质性相对较弱;②在第4层次基准面上升中期发育的水下分流河道侧向迁移活跃,纵向延伸过程中分流汇合作用强烈,以形成网状或席状连片砂体为主,但砂体间泥、粉砂岩夹层逐渐增多,储层非均质性增强;③第4层次基准面上升晚期和下降早期,不利于储集砂体发育,仅出现少量薄的水下分流河道、水下决口扇、远—河口砂坝砂体。

Compressive strength curing 7 days of lime-polishing powder binder is slightly higher than those of lime-fly ash binder, but amplitude of strength curing 28 days is obvious high, average amplitude is up to 190% and maximal amplitude is up to 210% comparing to fly ash-lime binder. Lime-PP binder preceded lime-FA binder in intenerate index of 7 days and 28 days under the same ratio of PP to lime condition.
结果表明:在相同配比条件下,石灰-抛光砖粉结合料与石灰-粉煤灰结合料相比,前者的早期抗压强度略有提高,28d抗压强度增幅明显,平均增幅达190%,最大增幅高达210%;前者的7d、28d软化系数均高于后者,具有更好的水稳定性。
