SX火山岩油藏氮气吞吐选井方法
WELL SELECTING METHOD FOR THE NITROGEN HUFF AND PUFF IN SX VOLCANIC-ROCK OIL RESERVOIR
摘要
Abstract
In order to solve the problem of the high watercut in the late period caused by the low porosity and heterogeneity in volcanic rock oil reservoirs,according to the geologic and development characteristics of SX Carboniferous oil reservoir and the features of the volcanic rock oil reservoir,the influencing factors of the nitrogen huff and puff were researched.With the help of the following analyses i.e.the remained oil distribution,the attic/loft oil location,the constant-volume body location,the bottom water energy,the single well potential,the wells with a certain nitrogen huff-and-puff potentials were selected.Taking the typical well as the example,the numerical simulation was conducted for the nitrogen huff and puff to predict the oil incremental condition.Finally the well selecting method in a block shows as follows:the remained recoverable reserves is more than 0.5 × 104t,the top of the structure,avoiding the reservoir peak,taking the reversed "Z" type watercut curve as the main form,the initial production of the oil well is up to 20 t/d.The method possesses a certain reference value for solving the problem of the water invasion in the volcanic rock oil reservoir.关键词
