Productivity Appraising Research Of Yingtai Gas Reservoir

Oil fields are developed deeply year by year, low quality oil and gas resources need to be developed, Existing analysis and evaluation methods are not fully applicable. Yingtai gas reservoir is one such low quality gas reservoir which is composed off our blocks,although both of them are volcanic reservoirs, They are divided into volcano karst reservoir and clastic rock reservoir, and each block exploration wells testing gas deliverability is very different from each other(2-180 thousand cubic meters), less condensate oil is generated during gas testing. Simple static geological research methods are not accurate for reservoir identification, the control of individual well inter connecting confine,and shape description in complicate aeolotropy gas reservoir. Currently, well test, early production test dynamic materials are widely used in description of reservoir dynamic feature in domestic and foreign. Parameters of the control of individual well inter connecting confine, the reserve volume of individual controlling and other pivotal development parameters are fine described by a large number of high-precision testing pressure materials and fine analysis of materials. And it can forecast production performance, and guide development planning and main development technique.This article for ma series of advisable analysis and evaluation technology by phase diagram discrimination method, experience statistical method, multi-parameter deliverability analysis, gas well testing,deliverability estimation, gas well dynamic analysis, deliverability calculation method in Yingtai gas reservoir.In consideration of complexity of volcanic reservoir, and unique feature of Jilin oil field condensation reservoir.Now researchers need to deeply understand volcanic reservoir connectedness, individual well inter connecting confine, potential of gas well deliverability increasing, the influence bottom water coning, horizontal well effectiveness evaluating. It is very valuable to achieve security and efficiency of deep zone gas exploitation.
