Study On Testing Technology And Oil Of Jilin Oilfield In Southern Songliao Basin Block Pre Wells

In the process of oil and gas exploration and development, well testing technology is an important part of reservoir description technology, it is encountered in the process of drilling oil and gas shows make an accurate evaluation, under the production performance of oil and gas field development important means of reservoir parameters. Well test technology developed in the 1930 s, after constantly developing, has become an important means of understanding and evaluation of reservoir. With the continuous development of computer, the modem well test theory and interpretation technology is put forward by using system engineering theory to explain the process of well test data, the pressure curve of the early, middle and late three phases model choice, judgment, analysis of the inner border curve fit, dimensionless inspection, history curve simulation test and so on many analysis, to determine reservoir model and seepage parameters. On the basis of the evaluation of reservoir capacity, boundary types and properties, hydrodynamic characteristics, damage degree and the mechanism and dynamic characteristics of oil saturation, again by these characteristics determine the correct way of completion scheme and measures, to calculate the dynamic reserves, this makes the reservoir performance evaluation is becoming more and more precise.This study mainly aimed at the common problems existing in jilin oilfield well test technology to standardize research and comprehensive evaluation, based on the investigation of the similar oilfield in China, based on oil and gas industry standards, by means of well test interpretation software, focusing on technical difficulties in jilin oilfield well test research, the research for well test interpretation methods, so as to better standardize the field test and data interpretation, provide reliable basic parameters for oil and gas field development and adjustment. To do it from the device in oil production companies of jilin oilfield, the specification of the operation process, interpretation, evaluation, so as to improve the quality of dynamic monitoring and utilization of test data, meet the needs of reservoir engineering and geological research work. On the basis of comprehensive standardized study and focus on comprehensive evaluation for typical oilfield, the suitability evaluation study on the interpretation and evaluation method, give full play to the well test technology of dynamic monitoring.Existing in the oil field, this paper try to well test interpretation of "early, Wells, layering, and the pump test data of the determination of reasonable interpretation and shut-in time" five big technical difficult problem, the research developed a new method, especially through the studying of horizontal well and creating a Model of well test, this paper try to find out the way to interpret horizontal well suitably and effectively.and test and verify the way suitable and reliable by instance analysis.
