A Study On Steam Injection Development Technology Of Heavy Oil Reservoir For Cretaceous System In Pai 612 Area Of Chunfeng Oilfield

Pai 612 wellblock of Chunfeng Oilfield locates in the northeast of Chunfeng Oilfield, it’s characterized by high crude oil viscosity, shallow buried depth, thin thickness, low formation temperature, insufficient natural energy, Conventional exploit methods is difficult to effectively develop, resulting in no large-scale development be carried out in quite a long period of time. For the purpose of scientific and effective development of the reservoir, using integrated knowledge and techniques of reservior geology, logging geology, structure geology, the thesis analyzes the reservoir characteristics of this area. Based on the study of reservoir characteristics, using the techniques of numerical simulation, exploration and development data of this area, depending on test data of drilling, logging, oil testing, indoor experiment, establishing the reservoir numerical simulation model of this area, fitting production history data and researching on the development technical limits of the steam drive well type, reasonable well pattern, well spacing, injection production parameters, steam injection intensity. Researches above provide the basis for the compilation of the steam injection development scheme of Cretaceous of Row 612 wellblock of Chunfeng Oilfield, prediction of development indexes, and realizing the development efficiency and the ultimate recovery rate maximization in the end.
