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This thesis is to analyze the project of ertan hydropower station in order to have an optimizing selection of the place for sand & stone by the means of systems analysis. this thesis will built a system to seek a best scheme about optimizing selection of the place for sand & stone by the means of analyzing and counting the basic data, building different mathematical modeling on base of man - made & machine - made stone, using dug stone and different sources of crude stone and the mixture of several material
