The Application Of Fine Reservoir Evaluation In HeXiWu Tectonic Belt

In recent years, with the constant improvement of the degree of exploration and development, in northern hebei central resource to replace the situation is very tense, insufficient reserves available for development has become increasingly severe, XinOuDai, new oil and gas exploration in the field of more and more difficult, at the same time the increase in water cut in old oilfield, production decline is serious. In order to realize low cost, benefit and sustainable development, while strengthening exploration for new discoveries, is bound to increase reliance on reservoir evaluation on the basis of integration of production, this is not only China, huabei oilfield objective actual needs of the complex geological conditions, and solve the contradictions of the resources to succeed and improve overall benefit of oilfield exploration and development needs.Look from oilfield are faced with the situation, it is after many years of exploration and development of reservoir evaluation objects more complex, the difficulty will be more and more big;2it is high quality for the development of reserves, less stable oil field production base is large, risk and difficulty also bigger and bigger; Three is drilling, development cost rising, the high cost will make the pressure of rolling exploration and development faces great difficulties.The research of this paper is to solve the key problem to reservoir evaluation under this situation, through the HeXiWu tectonic belt, the direction and method of reservoir evaluation work to find, find out the key factors to reservoir evaluation progress has been slow. In this study to deepen the geological understanding at the same time, in combination with drilling, logging and seismic data, the known researches in reservoir, from known to unknown, construction of oil and gas accumulation mode, partition fine piece of layered system to carry out the various traps, according to the "based on zones, the overall evaluation, step-by-step implementation, the key breakthrough" the principle of selecting the location, obtained a better effect, achieve production reserves in order to succeed. Mainly embodied in the "five fine", that is, fine stratigraphic correlation, fine horizon calibration, fine fine fine structure interpretation, reservoir research, trap evaluation, in fine of conventional oil and gas evaluation at the same time, to break the bondage of inherent ideas, emancipate the mind, innovate ideas, reconstruct hydrocarbon accumulation pattern, In11fault block, deployment22well, Among them4appraisal well,18mouth development well, a preliminary calculation of new proven oil geological reserves of245.62×104t.
