Research On Horizontal Well Deployment And Tracking Adjustment Of The Hainan No.3 Block

Hainan 3 piece of oil and gas are mainly distributed in the north of 15-15~11Wells in Hainan area,about 74.6% of Hainan 3 piece of total reserves.Aiming at Hainan 3 pieces of 15-15 bloc,from 3 d seismic fine interpretation,reservoir inversion,as well as the structure,reservoir geological modeling,sedimentary facies and residual oil distribution,etc,to carry out the research,the concrete research content is as follows:First from the deployment of major reservoir horizontal well screening;The main reservoir reservoir fine description and geological modeling;Major reservoir residual oil distribution study;Hainan 15-15 pieces of horizontal well deployment;To deploy horizontal well track adjustment from several aspects such as research,and carried out on the oil reservoir fine description,provide data for 3d geological modeling basis;The Petrel software,establishes the structure modeling,sedimentary micro facies model and property model,predicted the interwell physical parameters of distribution.Second,about 15 to 15 pieces of the development phase,from the different stages of oil field production characteristics,production characteristics,see who characteristics are summarized.On this basis,the main types and the status of the water drive reserves of waterflooding effect,the comprehensive utilization rate of water cut and water injection,energy level,the oil layer use condition,oil recovery rate,encryption effect,way of recoverable reserves of oilfield development,formation,,well pattern well spacing adaptability conducted a comprehensive analysis,the block reservoir longitudinal distribution is relatively concentrated,the hole is not too long,reservoir conditions,reservoir types,and reserves abundance(300 x 104t/km2)is lower,unfavorable and slicing.Is 300 m spacing on the implementation of oilfield.Under Ci Jing distance,better sandbody connecting,connecting factor 83.6%,basic reasonable well spacing,injection-production system is difficult to improve the exist in the mining at the same time,the problem such as the contradiction between the layers.Finally,optimize the Hainan 3 blocks in horizontal well deploymen,through the analysis,thinking that the lower level of reservoir using still has large potential,based on the comprehensive analysis of the economical efficiency of oilfield development,at the current price of $70 a barrel,the static payback period is 1.2 years.Through research on Hainan 3 piece of horizontal well deployment and tracking adjustment,which can guide horizontal well’s deployment of this module and provides the theoretical foundation for the future of deepening development,adjustment,and the improvement of development effect.
