针对苏14井区储层低压、低渗、非均质性强的地质特点,开发先导性试验中大规模压裂沟通砂体效果不明显,增产效果不显著,以及80%以上的井钻遇盒8上、盒8下和山1等多层的实际,采用分层压裂沟通多个储层、合层开采提高储层储量纵向的动用程度,达到了提高单井产量,实现经济有效开发的目的.
針對囌14井區儲層低壓、低滲、非均質性彊的地質特點,開髮先導性試驗中大規模壓裂溝通砂體效果不明顯,增產效果不顯著,以及80%以上的井鑽遇盒8上、盒8下和山1等多層的實際,採用分層壓裂溝通多箇儲層、閤層開採提高儲層儲量縱嚮的動用程度,達到瞭提高單井產量,實現經濟有效開髮的目的.
침대소14정구저층저압、저삼、비균질성강적지질특점,개발선도성시험중대규모압렬구통사체효과불명현,증산효과불현저,이급80%이상적정찬우합8상、합8하화산1등다층적실제,채용분층압렬구통다개저층、합층개채제고저층저량종향적동용정도,체도료제고단정산량,실현경제유효개발적목적.
Su 14 well field has geological features of low pressure, low permeability and strong heterogeneity. Pilot development test showed that it didn't achieve the desired effect of sand connectivity by large-scale fracturing, and the production was not significantly increased. More than 80 % wells encountered layers of HeSrap , Hegbouom ?and Shan. In this condition, separated layer fracturing was applied to link up multiple zones, and multi-layer commingled production was used to improve the recovery extent of the vertical producing reserves. As a result, single well production was increased, and the purpose of cost-effective development was achieved.
