Ordovician Reservoir Of The Tahe Oilfield Reasonable Capacity And Oil Production Rate,

The exploratory development process of Oil Field is a ceaseless process to know a reservoir. Though there has been lots of methods and techniques to know and evaluate a reservoir at present, it is still very difficult to evaluate the Tahe Oil field, which is too complicated to be known clearly with those current techniques. We have to face the complexity of it and study the productability of a well and the best production rate of the reservoir to keep a long-term high and stable rate. In the development of the Tahe Oilfield, it has a great impact on gaining as much as possible from the wells and developing the field more economically .This paper gives some advice on the ranges of reasonable well productability and the best production rate of the reservoir basing on summarizing the geological characteristics and performing analysis to make the development adjustment of the reservoir more available. It includes:It emphasises on the anisotropism of the reservoir both on portrait and landscape orientations which cause the difference of productabilities of wells to show the complexity of the Tahe Oilfield.We study the relations among the production index, reservoir richness, tectonic location, flowing pressures, productabilities and decline rates and summarize the trends of production, water cut and decline rate basing on the perform data we've got now.We give a rough plot of the blocks according the productabilities and study the best production rate of wells and the reservoir in different blocks and under diferent well numbers by the means of contrast, formula caculation, and simulations.The economy evaluation is also been done to make sure that the suggested production rate is available at current economic condition.
