| Based on a great quantity of dynamic and static gas reservoir data from well logging, well testing and exploitation ,this paper studied gas reservoir structural detail , reservoir spatial distribution and the relationship between gas well deliverability (QAOF)and reservoir factor(ΦH) systematically and in depth , described horizontal distribution of remaining reserves by using numerical model, and according to current gas reservoir preesureN fluid saturation and remaining reserves distribution, analysed the key affecting factors about gas reservoir exploitation, producing trouble area reserves in west and achieving the entire reservoir high efficiency exploitation. In this paper, geology demonstration about the horizontal wells optimized was dependable. This paper firstly used horizontal well technology to increase production in Sichuan province.Combining dynamic and static gas reservoir data ,this paper developed gas reservoir fine description about target area , established tridimensional geologic model, which reflect actual gas reservoir character; This paper first used gas reservoir numerical stimulation methodology, the relationships between geology target parameters and deliverability to predict development effects and obtained satisfactory result.Adopting modern well test analysis, this paper developed build-up testing and deliverability testing about horizontal wells, through these tests, acquired formation parameters , flow parameters , deliverability equation and AOF, which were dependable and offered scientific references for estimating horizontal well effects, establishing reasonably production schedule and managing production performance.Using practical drilling , drilling , production performance datas and well test analysis achievement of M75-H , and adopting numerical simulation methodology , the information of trial production for near 1 years has carried out history matching.On this research foundation, the development index of horizontal well... |
