胡尖山油田安83区块超低渗油藏井网适应性分析

胡尖山油田安83区块长7油藏是以"三低"(低压、低渗、低产)为特征的典型特低渗透油田,资源潜力大,目前控制地质储量1.3亿吨,但储量丰度底,隔夹层较发育,储层物性差,开发难度大,投产井单井产能低。本论文通过对该地区的构造特征、沉积相特征、油藏特征、及所采用的6种不同开发试验井网井排距(矩形、菱形反九点、正方形、水压裂、水平井等井网)的试油、试采、工艺改造措施等进行分析对比,探索出一套适合长7油藏合理的开发技术政策,认为水平井井网在胡尖山油田长7油藏开发中有更好的适应性,为胡尖山油田的快速上产提供了强有力的支撑和保障。

The oilfield safety Hujianshan 83 block of ultra-low permeability reservoirs well network adaptability analysis

Hujianshan oilfield safety 83 blocks long reservoir based on "low" (low-voltage, low-permeability, low-yielding)is characterized by typical ultra-low permeability oil fields, resource potential, currently controlled by the geological reserves of 130 million tons, but reservesabundance end interbeds relatively developed poor reservoir properties and difficult development, into production wells well productivity. The papers by the structural features of the region, and sedimentary facies characteristics, reservoir characteristics, and six kinds of different development test wells net wells row spacing the inverted nine (rectangle, diamond, square, water fracturing, horizontal wells well net) oil testing, production test, process modification measures is analyzed and compared, to explore a set of suitable length the 7 reservoir reasonable development technology policy, and that the horizontal well in the long Hujianshan oilfield 7 reservoir development better adaptability to provide strong support and guarantee for oilfield Hujianshan's fast on the production.
