Abstract
Horizontal well fracturing technology is an effective way to develop the hard-to-produce low permeability reservoirs, but horizontal fractures (low angle) are usually formed when fracturing Chang-6 shallow oil reservoirs with low permeability, which affects the actual construction effectiveness. In order to better guide the ifeld fracturing design and construction for horizontal wells of Chang-6 shallow oil reservoir, the porosity, permeability, oil saturation, shale content and seepage coefifcient were used as main parameters, and the reservoirs of horizontal segment in Qiping-1 well was divided into 5 lfow units, and evaluation was conducted to typesⅠ,ⅡandⅢlfow units. According to the division of lfowing units, the parameter design of number of horizontal fractures, fracture location, half length of fractures was completed for Qiping-1 well. The analysis of ifeld fracturing effectiveness shows that this design meets the reservoir features and development requirement of Chang-6 shallow oil reservoirs in Yanchang Oilifeld. The productivity of single well was increased greatly. Horizontal well development of Chang-6 shallow oil reservoir enjoys a favorable prospect.关键词
