手撼試驗-
Abstract : the stimulation treatment of & quot; loosening rock by the dilatancy of explosive waves & quot; is tested in the casing well 4242 for studying its result and its influence on casing. the result of the field test shows that this test is successful in technology, the oil production of the well is 4 times as much as that of it before the test ; the deformation of casing is local, and the result of the strength calculation shows that the deformation will not destroy casing
文摘:為了研究「壓脹松動」增產技術的增產效果和對套管的影響，在延長石油管理局子長油礦對4242井進行了現場實驗.該技術採用強動載波在地層深處疊加的方法，造成壓脹條件，松動巖石，增大近井帶滲透率，提高油井產量.施工后，該井產量增加為原來的4倍多.本次實驗工藝上是成功的，首先是按設計要求引爆了炸藥，其二是由於採取了保護措施，使套管變形局限在施工段處，不影響下泵，不影響油井生產;套管強度校核分析也證明了套管不會破壞.施工后地質效果明顯 -
Look back generally to elaborate the development and present situation of the stress - strain model of soil. according to a great deal of data of the test and research of zipingpu reservoir concrete faced rockfill dam ' s material, suggest the more reasonable stress - strain - volume change equation to contain strain softening, dilatancy ( shrinkage ) of the no viscous moraine and gravel. suggest the method to gain the model ' s parameter
較全面回顧闡述了土體本構模型的發展和現狀，根據紫坪鋪面板堆石壩築壩料的大量試驗研究，提出相對合理的應力應變關系方程，以反映土體的應變軟化、剪脹性，並提出模型參數的求取方法，求取模型參數。 -
Lastly, by comparison between calculation results of the three models and the test results, it has been found that the three models can all stimulate the softening and dilatancy characteristics of loess
最後，將三種模型的計算曲線與試驗曲線進行比較，表明三種模型均能模擬土的軟化和剪脹特性。
