低渗透砂砾岩油藏油水运动规律研究
STUDIES ON THE OIL-AND-WATER MOVEMENT LAWS OF LOW-PERMEABILITY GLUTENITE RESERVOIRS
摘要
Abstract
Yan No. 22 Block of Yanjia Oilfield (Shengli Oilfield) belongs to deep low-permeability glutenite oil reservoirs. In the course of the oilfield development by water flooding, the movement laws of both oil and water are becoming more and more complex. On the contrary, the movement restricts the development effects. Therefore, the laws must be mastered soundly to effectively control the underground movement of both oil and water. Considering the above, the oil and water relative permeability curves in the production horizons are changed into the relation curves between water saturation and the ratio of the above two permeabilities. Then integrating the implication of watercut, the laws of water production is analyzed. On the basis of the above, the vertical and horizontal distributions of both oil and water and the vertical movement laws are studied with the help of capillary pressure study of the production horizon. All the achievements studied above have provided a certain evidence for the adjusting and tapping decisions at the late period of oilfield development.关键词
