Paper Title:
Design and Practice of Steam Flooding on Anisotropic Heavy-Oil Reservoir with Edge-Bottom Water
  Abstract

Liaohe block J is a super heavy oil reservoir with relatively strong anisotropy and active edge-bottom water condition. After more than two decades of huff and puff production, the block now reaches a low production rate period, and the local part of the block also encounters serious edge-bottom water invasion. Now steam flooding is used as a switching method to invert the production decline tendency. Applied with thermal recovery process and numerical simulation method, reservoir pressure at flooding conversion, pressure control in steam flooding, injection-production parameters and well pattern are used to optimize the key techniques of steam flooding design. The design results are as follows: the reservoir pressure at flooding conversion as well as during steam flooding process should be controlled below 5 Mpa; the unit volume steam injection rate is 1.65t/d.hm2.m and the bottom-hole steam quality of injecter is no less than 53%; the injection-production ratio is 1.1:1 and inversed 9 point pattern with a 83m well space is used. The steam flooding pilot has been carried out for more than 2 years and obtains favorable benefits.
