英文摘要	The conglomerate reservoirs in the Dongying Depression, Bohai Bay Basin have such characteristics, poor physical properties, strong heterogeneity, and poor well adaptability. The use of radial drilling optimization studies can improve the utilization rate of reserves, balanced injection patterns, and ultimately improve recovery. In the longitudinal direction, the light flooding through, the use of poor reservoir implementation radial drilling, improve reservoir heterogeneity; in the plane, one fit well network by varying the direction of change inevitably cause stress direction well network do not match. the second is a variable length adaptation by well spacing, reducing the injection well spacing, improved utilization of reserves, the third is by plane to avoid flooding, water flooding achieve balance in all directions. Currently implemented in Wing 1 of low permeability sandstone and conglomerate reservoir radial boreholes 7, well productivity had increased more than 2 times after the implementation, and slowing diminishing reserves utilized effectively improve yield good results, but through the radial drilling hole balanced planar water flooding, improve vertical suction conditions, to achieve the purpose of adapting well network.; EI; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 113-117; 25
