华北油田复杂油气藏评价技术研究与应用

渤海湾盆地地质条件复杂,油气藏类型丰富.针对渤海湾盆地岩性油气藏、地层油气藏、构造一岩性复合油气藏、低渗透油气藏、复杂断块油气藏等复杂油气藏的评价技术难点,开展了油藏评价配套技术研究,建立了复杂油气藏评价的技术思路和技术对策,加大了适用配套新技术的研究和应用,深化总结和形成了针对华北油田复杂油气藏评价研究的主要做法,探索了一套适合复杂油气藏评价的实用技术,并在实际应用中取得了良好成效.

Research and application of complex reservoir evaluation technology in Huabei Oilfield

Bohai bay has complex geological characteristic and different types of reservoirs. The evaluation of complex res-ervoir meets many difficulties, such as evaluation of lithologic reservoir, stratigraphic reservoir, structural-lithologic composite reservoir, low permeability reservoir, complex fault-block reservoir, etc. To solve these problems, reservoir evaluation tech-niques were studied, and strategies for evaluation of complex reservoir were established. Research and application o{ new tech-niques suitable for the situation were conducted. The method for evaluation of complex reservoir in Huabei Oil Field was pro-posed. This paper gives a set of practical techniques adapt to complex reservoirs and good results has achieved in practice.
