Three components of peroxide in the activator amongwhich have the different decomposed temperatures made the Vinyl-ester resinsolidified heat discharge increased that gained a bigger solidified degree. Theactivator-adopted quantity can dramatically affect the casting samples performance:eg. When use 1.0-1.4 portions of activator, the casing sample can reach its maximumTensile strength and Bend strength; when use more activator, the polymeric meshworkcontracted which embrittle the casing sample and reduce the dynamic performance; Inthe Pultrusion processing, when CF composed of about 60vo1%, more demould agentcan bring the better processing but degrade the CFRP, normally use around 1.2 portion.

采用具有不同分解温度的三组分有机过氧化物引发剂，乙烯基酯树脂的固化反应放热量增加，固化程度提高；引发剂用量对浇注体的性能影响很大，在用量为 1.0~1.4 份时，浇注体拉伸强度剂弯曲强度达到最高，过多的引发剂使聚合网络减小，浇注体变脆，力学性能降低；在拉挤成型工艺中，碳纤维的体积含量一般为 60%左右，脱模剂增加使加工性能好转但会使复合材料性能下降，一般用量为 1.2 份。

The Solidification temperature range was defined as 110-200℃ by DSC analysis. More accelerant used can increase the casing samples dynamic performance, but more than enough accelerant can induce a severe solidified reaction that result in a smaller polymeric meshwork and reducing the sample's performance. Normally the Accelerant dosage can be 2 portions; The Epoxy resin CFRP has a obvious better performances than the Vinyl-ester Resin CFRP, i.e. had a Bend Strength of 1516MPa, LSS of 85MPa, also Tg raised to 195~C~ When used the end-carboxyl polyether to reinforce the epoxy resin, the casing sample's SS, BS and Crack Elongation all increased geminately. The CFRP performance also increased a little, that is because the performance of the CFRP mainly contributed by the CF. The reinforced resin improved the interface between the CF and resin that contribute to the little increasing.

通过DSC分析确定了该环氧树脂的固化温度范围为110~200℃，促进剂增加会提高浇注体力学性能，但过多的促进剂会使固化反应剧烈，聚合网络减小，使浇注体性能下降，一般用量为2份左右；以环氧树脂为基体的复合材料性能明显比以乙烯基酯树脂的性能提高，弯曲强度达到1516MPa，层间剪切强度达到85MPa，同时Tg也上升到195℃；用端羧基聚醚增韧环氧树脂后，其浇注体的拉伸强度、弯曲强度及断裂伸长都成倍增加，复合材料的性能也有所提高，但提高幅度不大，因为复合材料的力学性能主要由碳纤维承担，树脂增韧后改善了复合材料的界面性能。

Therefore based on analysis of the status quo and the bottleneck points of the drilling and completion, effective measures have been put forward, including optimization of casing program, application of UBD and compound drilling, adoption of nonpermeable drilling fluid, diverting technology, rotating while cementing, casing optimization, horizontal drilling and extended reach well technology, etc.

为解决上述问题，在对钻井完井现状和难点进行分析的基础上，提出了有效的应对措施，主要包括优化井身结构，推广应用欠平衡钻井和复合钻井技术，采用非渗透钻井液、屏蔽暂堵技术和旋转固井技术，优选套管射孔完井，开展水平井和大位移井钻井工艺等。

Four years later, in a 1996 workover, well E-1 was successfully pressure tested above the deep casing collapse location, even though ovalization and tight spots existed above the collapsed casing.

4年后，在1996年修井，以及的E - 1是上述压力测试成功的深层套管崩溃的位置，即使ovalization和严密点以上倒塌套管存在。

The calculating results are compared with the test data in available literatures and FEM results. The research results show that the plastic hinge model is precise and correct, which can satisfy with the actual engineering demands. The collapse pressure of perforated liner casing decreases with phrase angle, initial ovalization and diameter-thickness ratio increasing, and increases with the yield stress. The phrase angle and initial ovalization have greatly influence on the collapse pressure. The collapse pressure of perforated liner casing is slightly changed with the diameter and density of perforation when the diameter and density are smaller than 12mm and 120 shots per meter, respectively.

计算结果表明：筛管抗挤强度的塑性铰模型具有很高的计算精度和准确度，可以满足工程实际需要；筛管抗挤强度随着射孔相位角、径厚比和初始椭圆度的增加而降低，随着屈服强度的增加而增加，相位角和椭圆度对筛管抗挤强度影响比较显著；在射孔直径小于12 mm、射孔密度小于120 孔/ m 时，筛管抗挤强度随射孔直径和射孔密度增加变化不明显。

They may be working piece of another advantage of the casing, is used in when you need to quickly shoot can be as early as the chip-chests, completed shooting the film, when finished in a roll of casing, the photographer can detach a movie-chests, and immediately put on a new cartridges and shooting miss the crucial moment, in case of shooting Assistant, the surprint rediscussion of the film took out a volume of the new film, this procedure can be repeated; in addition, most of the 120 SLR computers may also have a different format, such as on-chip Bronica SQ-A, he will have 6-by-6, 6 × 4." and " 5,135 quanjing 135a standards of film cartridges.

随时可不不装不不装片匣的另一个弊端，是用在需给飞快不断拍摄时可预早在众个片匣不不装妥胶卷，当拍摄完片匣洋的一卷时，拍照师可以不不装下片匣不独立即不不装上另一片匣，减众在拍摄洋错失重给工夫的可能性，如有拍摄帮手的话，则可把已曝平的胶卷取不入再换上一卷陈胶卷，这样的历程可以屡屡举行；此外，不小局部120独镜反平机也有差别片幅的片匣，如Bronica SQ-A，便有6×6，6×4.5，135&全景&及135尺量量的片匣。
