Effect of sedimentary facies distribution of special low abundance oil layer on horizontal well pattern development

LIU Yue-tian,ZHOU Fei,ZHANG Yun-xin(Key Lab of Petroleum Engineering of Ministry of Education,China University of Petroleum,Beijing 102249,China)  
The special low abundance oil layer is particularly thin, so,the fluid diversion of formation,namely,the feed flowing capacity,is the key factor affecting the development.The feed flowing capacity depends on formation physical properties and sandbody thickness,and these 2 factors are relative to the distribution of sedimentary facies.So,the effect of sedimentary facies distribution on horizontal well pattern should be considered.Different location and direction relationships between the horizontal well and sedimentary facies belt and matter sources direction have been designed,and numerical simulation method has been applied to the research on the effect of matter sources direction and facies belt distribution on horizontal well pattern development to optimize well spacing.The horizontal hole section direction ought to be vertical to the sediments source direction,and when the horizontal well penetrating many facies belts,the distribution sequence of facies belt has no obvious influence on development results.When the horizontal hole section is in inter-river sand bar and is adjacent to the drainage line,the cumulative oil production of horizontal wells is higher than that of the horizontal hole section in the drainage line and in sand sheet.
