Abstract

Abstract:

Laboratory physical simulation experiments and reservoir numerical simulation methods were used to study the development mechanism of cyclic in situ combustion (ISC)of heavy oil reservoir and other related reservoir engineering problems. The research has shown that cyclic ISC has multiple action mechanisms, such as upgrading the crude oil through cracking and reducing the viscosity by heat and the dissolution of flue gas. Therefore, the development concept of cyclic ISC is tenable on a theoretical level. According to the reservoir characteristics of and the requirements of fire flooding for cyclic ISC, the well pattern design principle and the optimization method of cyclic gas injection volume and gas injection rate were given for the development mode of cyclic ISC. Meanwhile, this paper put forward the requirements for the ignition, anti-corrosion processes and other key technologies in the implementation of cyclic ISC. The result has been applied to the cyclic ISC pilot experiments of M8 block, Inner Mongolia, and has achieved technical success. This technology is applicable to the deep, ultra-deep and water-sensitive reservoirs difficult to be developed by steam injection.

Key words: cyclic in situ combustion, water-sensitive reservoir, physical simulation, numerical simulation, field test

摘要：

通过室内物理模拟实验和油藏数值模拟的方法，研究了稠油油藏火烧油层吞吐开发的机理和相关油藏工程问题。研究表明：火烧油层吞吐具有热力降黏、原油裂解改质和烟道气溶解降黏等多重作用机理，火烧油层吞吐开发理念在理论上是成立的。结合火烧油层吞吐面临的油藏特征和转火驱的要求，给出了火烧油层吞吐开发模式的井网设计原则、周期注气量和注气速度的优化方法，并指出了火烧吞吐实施过程中对点火工艺和防腐工艺等关键环节的技术要求。研究结果应用于内蒙M8井区火烧油层吞吐矿场试验中，取得了技术上的成功。该技术适合于深层、超深层以及水敏性等难以注蒸汽开发的油藏。
